The Graco SlimFit3 LX is a 3-in-1 convertible car seat that transitions from rear-facing harness (5-40 lb) to forward-facing harness (22-65 lb) and highback booster (40-100 lb), making it suitable for infants through older children. Measuring 16.7 inches wide, it is designed to fit three across in most vehicles, a feature highly praised by users for compact cars and families with multiple children. Key features include a 10-position No-Rethread harness, breathable mesh AirFlow channels, InRight LATCH, and a Rapid Remove cover; however, some users report that seat belt installation can require extra effort to achieve a tight fit, and the crotch buckle is shallower than other models.

Actually a slim car seat!

SwissMrs19

This is actually several inches slimmer than the other “slimfit” graco car seat and has made it so much easier for us to fit three car seats across in our 4Runner! We currently have the other slim car seat (that isn’t very slim at all lol), an infant seat and this seat and they fit snug but comfortably. We will definitely be buying this one again when our baby outgrows the infant seat! It was very easy to install.

I’m overall great car seat

Vrod149

I got a month ago and it’s been great. Toddler loves the seat. Easy install and gave much more space.

Great compact seat for 3 across

MrsWelch

Bought these so we could be 3 across in the back of my sedan. They’re a great size and I actually like that they hug my kids a little closer, and cup holders are closer too than in our old seats. Installation and safety are always my top reasons for choosing Graco. It’s very straightforward and simple and trustworthy!

Best car seat for multiples

Cruz Family 20

I have 4 kids (11,4,3, and 1) when our 3rd baby was born we struggled finding a carseats that would fit in the back of our sentra. We could fit 2 but then our bigger kid was squished. Then we found these. We started with just one then ended up buying our 3rd last year when our youngest was born. They all 3 fit in the car and are easy to install. They are also easy to take apart to clean and button back together like a charm. Anytime we need to adjust straps we can do it with them in the seat in like 5 seconds. We will never buy a different carseat these are the best!

Fits great and safe

SumYan

We bought 2 one for our child forward facing and one backwards facing. We love them, the kids love them. We can fit 2 scroll in our Kia carnival, VW Atlas and ford focus. It has mesh on the sides to allow air come in. We would recommend

Excellent carseat

Ambi

The car seat was very easy to set up. It is slim and fits well in a small car. I really like how easy it is to adjust the height and straps.

Great car seat

Jjjj9

This car seat is comfortable for our child, and allows for us to fit 3 car seats in a small backseat. Very happy with the limit.

Good car seat, slim function is ideal

AFrodo

Purchased this car seat to move our 18 month up while we used her original car seat for new babies. Hoping to graduate the twins to the same in a year and half or so and fit the three across a bench seat in vehicle. Car seat is a little harder to install than the ones with the separate base. I feel that even though the recline is set correctly, our daughter’s head does tilt forward a little. I would be hesitant to use with young babies.

Exactly as advertised

bob273443

I was looking for a car seat that fits into a small car, and can be easily carried around. We have two cars, and I am often moving the seat from one car to the other. SlimFit is easy to install with the latches, and light enough that it is not too hard to carry.

Great car seat for compact fit

Sammie E

This car seat is constructed with high quality materials and was very easy to install. It is also very compact making it the perfect second car seat for our compact sedan. We previously had the Graco Turn2Me and have been very satisfied with both the quality of Graco car seats, the lifespan of the seats compared to other brands, and the amazing Graco customer service. We are already looking forward to buying a second SlimFit for our other car.

Great car seat

PhilH

Very narrow and shallow. Fits great in the cars and the kids still find it comfortable

comfy slim car seat

CKent

great car seat!! love the slim design so it fits in our cars better for our growing family. Easy and simple to install and never have to worry about safety with a graco product! Comfy car seat for my boys!

Great car seat

Sarah C D

Perfect fit it our car and our little girl loves it

Slimm

A Garcia

Its slim, fits perfectly. The new clips makes it easier to dettach.

Happy

Cydney B

This carseat was incredibly easy to install. Its sturdy, comfortable, and most importantly it is safe for my one-year-old. And the color is amazing.

Perfect for small suv

Sb1239987654321

Great size and not too cozy for as heat. Easy install and just overall love graco products! Tried even flos slim car seat model of this and returned it for this one instead!

Great car seat!

Jer M

This car seat is great! It fits really nicely in our car, and is really easy to get our child in and out of. The installation was easy and it seems comfortable for our baby. I love the fact that the cup holders can detach for extra space!

Perfect for 3 across

Caroline r

Just moved my baby to this convertible seat. It fits perfectly in my suburu outback with two Diono seats for my other kiddos. This seat is really nice, fit is snug but comfortable.

Comfy and fits well

MommaX7

It can be so hard to find something that fits well in a vehicle that a lot of seats just aren't built for. This seat was exactly what we needed to get our 1 year old safely out of her infant seat in our 12 passenger Ford Transit. It also fits well in our sedan with room for her older siblings next to her. The seat is comfortable, the color is cute, and she was so excited to have her own cupholders.

Graco slim fit

Ckenny23

This seat is great and works well. I like the slim design on it so grown ups can still have room sitting out back. I wish that you could remove the fabric in the seat to be able to put it in the washing machine and clean it easier.

Great in smaller cars

Catie R

We got the slim fit car seat for my crossover sized vehicle and it fits great. There is still plenty of room in the back seat for another passenger, and our baby is very comfortable in his car seat. Super easy to install too.

My research paid off, love this car seat!

C Fred

I did a lot of research before purchasing this car seat. I had my daughter in an infant carrier and she was getting too big, so I knew it was time to move up to a convertible seat. We drive a small car, a 2013 Kia Rio, and we are hoping to have another baby soon. My biggest priority was finding something that could fit in our backseat alongside an infant carrier. Specifically, I needed a car seat that would fit behind the driver when my husband was driving with the seat pushed back, because our infant carrier does not fit there when he’s driving, so if we are going to have another baby my daughter will have to be in that spot. Budget wasn’t my top concern, but I didn’t want to pay the price tag of some luxury brands. I found all of the resources on Graco’s website very helpful as I was measuring out the car and planning what to expect. I ordered the seat to be delivered to us and it arrived just a couple of days later, quite a bit faster than the shipping indicated it would take. The seat itself is awesome. Very high-quality, compact, and lightweight. It delivered on everything it promised. The safety features are top tier, and the latch system was super easy and quick to install. Not only will this fit next to our infant carrier, I believe there would be room to add a third car seat of this type in the back, although I certainly hope we have a bigger car by the time we are ready for a third baby! In the end, all my research paid off and I’m really happy with this purchase. I feel confident this car seat will be able to adapt to accommodate my growing family as our needs change. I would recommend it highly to others.

Great car seat

Mickey B

We like these car seats. They are compact, and fit my 3 year olds well. We needed new car seats after the foam inserts started falling off our old ones. After shopping around, and even buying a different one and returning it, we settled on these. I like that my kids are safe, and I appreciate all the protection, but it does make it hard to get them in the car seats. Our old design was much easier and sleek (though not as safe) I also wanted to rear face to the max size, but these car seats didn’t have a very high rear facing limit, and it was extremely difficult to get them in and out when rear facing. They are 33 lbs, so technically they still could, but this car seat doesn’t lend itself for that. Ultimately it was worth it for us to have a little bit more of a hard time as long as it keeps our kids safe.

Slim & Comfy

Bunny Mummy

It is so slim, I was worried my toddler wouldn’t be comfortable in it. But he seems to love it so far. It doesn’t have all the extra bulky padding, but is still soft and comfy. Also, love the airflow features.

It works.

Thomas I

No need for an overly drawn out review. The car seat does what it's intended to do.

Worth the price!

Mimi CJ

I was hesitant on the price, as I was purchasing for triplets, but these are high quality and provide peace of mind when it comes to safety.

Great Seat for 3 in a row!

Mom of 3 in Car Seats

Perfect car seat when you have 3 littles in seats still. This gives me the option to have all of my children in the 2nd row since they are slim enough to fit side by side. Very easy to install and also easy to take apart to wash. This is my 3rd seat and will be ordering more to put in their dad's truck.

Only purchase Graco!!!

Danie C

With two young boys and busy work schedules we have a total of four Graco car seats and love the safety features on all of them! We also have two strollers and cannot express how much we love the durability of each product!

Excellent compact car seat

AS8765

This car seat functions perfectly for us. It fits well in the small back seat of our FJ Cruiser. We have installed the infant car seat beside it proving it would work well for 3 across. It fits well in the center with plenty for room for my 6’4” husband to drive.

Three across!

Rosie Lord

I am super happy with how slim and still comfortable these car seat are! I drive a crossover and am able to fit 3 car seats across! Huge money saver not having to upgrade my car! Graco is such a reliable brand and our family trust them!

Great product!

Different one

We have loved our SlimFit3 LX 3-in-1 Car Seat for our little one. We purchased this a little over a month ago to transition out of the infant carry car seat and for our little one to use as she grows. The quality of this product has been great! We love the base latch on this model for ease of removing and switching to a different vehicle. With our older child we had the basic latches and the quick release of these is a game changer!

Love this car seat

Brower

I originally purchased this carseat in 2024 when my daughter went from an infant carseat to a convertible carseat. Recently we were in an accident where the rear of the car took the biggest hit. Long story short, her seat needed to be replaced, so naturally we re-purchased this model since it had kept her safe and basically injury free from the impact. We loved the slim profile and the mesh vents before, but we have a whole new appreciation for the durability and safety of this seat.

Great size car seat

LouC

Excellent car seat ! Love how it fits in car beside other seats

Great car seat!

Brittney E

We love this car seat and how much room it gives us in our car. My only complaint is installing it rear facing for infants. I find it a bit challenging. I'd recommend this more for children over the age of 2.

Love it

Your Public Name

It was easy to install and fits my 5 and 2 year olds perfectly. Helped us fit 3 across.

Great Slim Car Seat.

Samuel S

The slimmest model you can find in the market. Yes, this will fit 3 across, which wasn't the main reason we bought this as we only have 1 child. We bought this because we have a small car and didn't want the back seat to be taken over by 1 car seat. It is also very light, easily removeable and to install with the click in latch system. The meshed materials also keeps the child cool and happy in long car ride. We have taken this car seat in 3 international trips (Croatia, Mexico, Italy) and our child who is now 3 has no complaint. It is easily removable to wash. We also have another model (the TriRide, which is about half or 2/3 the price of SlimFit3LX) in another car, and I would say it is worth spending the money on the SlimFit3LX. The materials, latch systems, size, weight, construct is much much better.

Great car seat

DeniseP

This is my 4th Slimfit3 and 8th Graco car seat. Easy to adjust and install. I've bought nothing but Graco since one of their seats saved my family in a rollover car accident by stopping the roof from fully collapsing several years ago.

Finally a way to have 3 kids fit in back seat!

ChrisBJ

Finally all 3 kids can fit comfortably in the back seat of my small SUV! No complaints from the kids after a couple of 14 hrs trips (well, plenty of complaints, but none that related to the seats or to their comfort!)

Perfect for growing family!

Chloe B

I wish I just bought these to begin with. I bought different carseats, but the SlimFit3 LX 3in1 makes the most sense if you plan on having three across in most cars! The quality makes me feel like my babies are extra safe and relieved my anxiety! If you are thinking about best choices with a growing family this is it!

Fit three in a compact car!

Mamadriver

This is my second one and it has been working great for us! Easy to put on and off to wash and gives us the option to put three car seats in a compact car. We once had to give our friend’s four year old a ride and we fit two of the slims and one reg size Graco car seat no problem!

Great carseat

Veronica C

Easy to install, roomy. I was afraid it being slim, that my child may not have enough room, but she had no issues! I’ll be getting another for my other toddler. We have a 9 yr old and she doesn’t feel squished in the back either.

Great car seat!

PigTails

I also have a Graco Extend2Fit. And I honestly wish I just had 2 of these. While I have not tried to clean it yet. I love how much more airflow this car seat has. It also has some nice design features that really make it feel quality.

Good carseat

hedgehog

Happy with this car seat. I like that the cup holders can open or close for more space.

Easy installation!

Mo Lewis

Purchased for grandmom’s car and are extremely happy with ease of installation and fit.

Safety first

Kdillon430

We recently purchased a second SlimFit for our other car because we loved our first so much. We appreciate the ease of install and how secure and comfortable our son is. It gives us peace of mind knowing he’s safe.

Easy install!

asimonette33

Super easy to install and love that it’ll last for so long!

Long time user!

ABreeze

I’ve used Graco products for almost 14 years. Grateful for an affordable and quality product!!

Slim fit 3in1 for the win!

Benjamin99

Knowing that my baby girl is gonna be safe for years to come has put my mind at ease. I have trusted graco products to move and protect my baby since day 1 and I’ve never had any sense of regret. Love this product and this company.

Great seat!

Missy89

My son absolutely loves this seat. It’s extremely comfortable and easy to install. I got this because of the safety rating and it’s ergonomically friendly. I love the adaptable cup holders as well.

Safe

KimRK

I bought this for my grandson. I don’t have much to compare it to as car seats are much different than they were 35 years ago. But it seems comfortable to him and seems very safe.

Love this seat

Christina218

We love this seat! It is such a cute color and it was easy to install. We love that the cup holders don’t come completely off so we can’t lose them. Straps are comfortable and safe. My only complaint is that the purple color shows every single stain and is impossible to keep clean.

Easy and basic!

LBme512

Recently purchased and I am pretty happy with it. One complaint I have is the size of the cup holders, they are too small for some of the water bottles I have. This is the first seat I have had this issue with. Other than that, I would say it is a decent seat overall.

Great Car Seat!

TheGreatOne

This car seat sat perfectly in my car. Easy to install and the best part is that its stable when it comes to driving. Graco is great! I definitely would shop again when I need a new car seat!

Easy install

Ed6092

Installation was super easy and my baby seems to like the comfort of the pads.

Great size for small SUV

Jazmin D

This is our second SlimFit 3-in-1 car seat and we love it. We have a small SUV and there is still space in the middle seat, after installing both car seats on each side in the back.

Great features!

Faprouse

My son is super comfy. Installation was easy. Safety ratings are encouraging. Cup holders are a plus!

Comfortable and safe

Nikkki

This is my second of this carseat. My child finds it and has always found it very comfortable. We got a second because of a car accident. My child was unharmed and didn’t have any whiplash. The seat seemed fine but getting a new one when in an accident is always safest.

Buy it now! Comfy and cute!

Mommy P

My one year old twins love this car seat! They are both some comfortable and love the cup holders! It has much more cushion than our formers car seats. We will be a graco family! We love the color and how it will grow with the children!

We LOVE it!!

MommyOf2xo

I love the versatility and how easy it is to install! We have a smaller vehicle and it fits perfectly. It had two setting for rear facing, 1 sits baby up more, 2 leans back a bit. I haven’t tried the others out since she haven’t gotten there yet but for far i love it! Our 1 year old seems to be pretty comfy in there!

Quality.

Mike S

Quality product for the price. Works very well. Comfortable for kids.

Perfect for my toddler

Hannah27

Love this car seat! I love how the cupholders can fold in making it easier to fit next to our other car seats. I also love the lower anchor belts on this one, way easier to install and uninstall, they work like regular seat belt buckles with the click part. Also I love the name of the color, my son’s name is Silas so it was meant to be! We also have the 3 in 1 snug fit in pink for our newborn and that one is also amazing!

Great fit, easy to install

KayF

2 of these fit well in the back of our Honda Accord with room to spare. That's the main reason we bought them! They're nice too, cupholders are a plus. Nothing fancy which I don't mind!

Amazing

NV96

I absolutely love this car seat! I got it three years ago for my first and definitely had to order another when my second was born. The seat literally grows with them so you save money in the long run.

Better for forward facing.

Sean123

Solid car seat and easy to use, for rear facing little ones legs to rest against the back of the seat.

Highly recommend for First Time Moms

Rocky1130

Great car seat for multiple little ones. Not bulky and fit wonderfully! Easy to install and take out. Cleaning and adjusting for growing kids is also easy. 5 stars!

The only way to ride

Just Dad

Now this is the how we ride. My boy been riding in style with the slim fit 3 in 1. It’s comfortable for him and I’m glad that we have a seat that will grow with him.

Excellent car seat

Shannynanny

I love the ease of loosening the straps, pads are washable, and buckles hang over the sides to keep out of way. I’m a nanny and purchased the car seat so I always have one on hand. I love that it’s easy to use and safe.

Excited to try

Loretta

One car seat versus multiple purchases. Hoping to fit multiple seats in the back of the SUV

Pink comfort

LaylaG

I like the quality and comfort of the car seat. It was easy to install.

Good seat

B945

Pretty good seat overall. Only using with a 6 month old so we'll see how it works as she grows.

Amazing!

Nia M

This seat is perfect for my daughter. She can ride comfortably in the front facing position. And I’m happy to have it as she grows until she needs the high back booster. Amazing!

Great, affordable car seat

Natalia I

I purchased this car seat as a second seat for trips home to visit family. Assembly was straightforward, the chair is compact, and the seat has excellent safety reviews and ratings. It was very affordable, and I highly recommend it to others.

Love IT!!

Daisy888

The color is amazing. The features are great. Love the reclining and the sitting features. The cup holders are pretty cool.

Easy to use/set up

LKpp

Easy to use and doesn’t take up much space. We had the infant carrier until this and this is notably less bulky. I have a midsize suv (rav4) and fits fine. Being able to move the harness straps up and down with the button is nice too and makes it easier to adjust as needed

Comfortable and reliable with child safety in mind

MayaC

The material is easy to clean , love that the seats grows with your child and can be used for few years . Easy to install , Fits well , in my car without taking up too much space. Overall , high quality , and well designed .

Great carseat!

CaitlinW

This car seat has been great for our family. We have a Honda CR-V, infant and dog and we can fit them all in the second row. It is tight but I'm glad we have the SlimFit seat so our dog has a little bit of room!

Felt Safe! LongLasting.

MarthaS

Loved it. My Son fit perfectly in this until 2 years of age. And I knew my son was safe. Was very durable. Made with great material and comfort. Easy to install.

Fits well in the back seat

AngieR

The Graco SlimFit Platinum 3-1 Car Seat has been a great addition to my family. I love that it grows with my child, which it is a good investment and I don’t have to buy another car seat. The slim fits better in the back seat specially when you have other kids in the back as well. It keeps my son safe and comfortable. It is easy to clean after any mess and the straps are easy to use.

reliable and practical

SofiaK

It is a great combination of comfort, safety and convenience. It gas a slim design that saves space in the car without sacrificing comfort for the child. The seat feels sturdy and well-made, the padding is soft, and the adjustable headrest makes it easy to grow with your child.

Save space, good carseat

I have 2 of these and I love these. It slim and still give my kids space for seat, not tie on them. It good because my infant can sleep straight without interupe or hot or tight in the carseat.

Comfy, compact

PaigeV

With three kids, I wanted a compact and safe car seat I could trust. My kids love them and they say this is the comfiest seat we have for them compared to grandparents seats

Safe and comfortable

Yinery G

The best investment for my baby's safety! This Graco chair gives me a lot of peace of mind because of its reinforced structure and how robust it feels. The harness system is very easy to adjust and level indicators help you make sure it was perfectly installed. It feels of a higher quality and my son is very protected. Totally recommended!

Graco SlimFit® 3-in-1 Car Sea

Baby01

5 stars for the Graco SlimFit® 3-in-1 Car Seat. The slim design is a huge plus, especially in a small car or when fitting multiple seats across the back. It’s very adaptable, with a smart 3-in-1 design that grows with your child, and the comfort is excellent thanks to its supportive, ergonomic build. Installation was straightforward, and it feels secure and well-made. Safety was a major factor for me, and this seat gives real peace of mind. Overall, it’s a practical, comfortable, and space-saving car seat

Great chair

MarcoLima

The SlimFit 3 is the best chair out there. Easy to set up and has all tje great security features to make a trip safe for your baby

Flexible and comfortable

Ariana9

I recently bought two of these car seats as my son already has one and I bought an extra two for my Car seat rental business . These car seats work wonderfully they're very comfortable they're easy to change depending on the age and size of the child they're very easy to install and I like how they are just slightly slimmer than a general model so it's easier to fit them in more cars. It is a great purchase and I would do it again in the future if I need more car seat seats for my business.

Cool stuff

Fun trips

Easy to install and remove. I feel very safe having my grandson in the seat when driving.

Great features and comfort

JW26

We just switched our son to his first big boy car seat and the Greco turn to me is perfect! It was easy to install, the turning feature is so convenient, and our son looks so comfortable and has way more room compared to the infant bucket car seat he was in. Overall, we are very happy with this car seat.

Really does fit 3x

ellbunns

Installation is so easy on this! Also it really does fit 3 across even in a compact sedan (Nissan Sentra).

Easy to install, perfect for 3 across!

Fish12

Installing this car seat is fast and easy. It has improved padding from previous version that makes a smooth ride for our kids.

Quality Car Seat

Delcal

It's a great budget quality car seat. The adjustments for the bottom strap is more difficult than our other Graco seat but our son is comfortable in both seats.

Great caraeat

This is a great car seat. It’s super snug and good fitting on my toddler. It is narrow just like advertised.

It is very good the truth, mainly for the price and the quality it gives to our little ones, it lasts from being an infant to very big, and what I like the most is that my car is not big and it is special in the

Best car seat!

ArionaB

My family and i absolutely love our graco car seats! We have had these for all 3 of our children. It is incredibly easy to take out & install, and it’s very comfortable for my children. I also love that all 3 can car seats can sit together in the back seat!

The Only Car Seat You Need

morganlea26

We absolutely adore the Graco Slimfit 3 in 1 car seat. The recline, padding, fit, and buckle are easy to use. It installs easily and fairly quickly. The weight limits are also great. It is wonderful for growing kids as it can be used for infants, rear facing, forward facing and as a high back booster seat. It work well in all of our vehicles including Honda CR-V, Honda Passport, Honda Pilot, and RAM 1500. It also has other beneficial accessories like cupholders which can fold back in when not in use. You can also fit 3 side by side in most vehicles. This is my go-to car seat for all my children!

A car seat the grows with your child

AbbyH

This car seat had an easy setup and was light enough to maneuver. Our son has been able to grow with the seat. The headrest is able to extend to fit the child’s height. The buckles are easy to work and tighten/loosen when needed.

Washes up great

Amy Mayhem

Crazy to use. Great support for my kids. Install was easy

Graco slim fit

Great car seat, light weight but still sturdy and safe!

Wonderful car seat!

TeBe

So easy to install and adjust to our baby. Literally took me 5 minutes from unboxing to the perfect fit!

Great seat, needed help to stablize

NCTM

Great car seat size for my second row bucket seats. It is relatively easy to attach to the seat. However, it is difficult to get the seat stable. It requires a lot of downward pressure to have a stable fit. I am a grandparent and needed help anchoring the seat.

SlimFit 3 Lx 3 in 1 car seat

Fits the backseat of car well and room for 2 children/adults passengers.

Good Quality - Some reading required

Dani H

I like the product. it does require some reading and youtubing to understand how to adjust the straps.

Exactly what I wanted in a car seat!

Allison123

Love it! It’s slim and can fit 3 in one row. Exactly what I wanted

Huge upgrade!

easy123

My 1yo absolutely loves it! She was getting a bit cramped in her infant carseat and is really appreciating the upgrade!

Great slim fit

We are tall and this helped us all fit in my husbands sedan rear facing!

Pros and Cons

Halfdeadmar

I was so impressed with this seat right out of the box. However it’s not the easiest to tighten and it seems like the head protection is too high but it’s where it has to be for the straps to come right above the shoulder in forward facing. I do love how narrow it is though. Not my favorite but it will do.

Fantastic product

Anonymous

We bought this car seat originally for our first born and came back to it for our second child. Both fit great in the backseat. They are comfortable and safe for the babies. Easy to install and adjust as needed for best sitting posture/ ergonomics. Highly recommend it for new parents, small or big vehicles.

Slim without sacrifice

Looks sleek but comfortable, definitely slim without sacrificing any safety or comfort. Love!

Fits a Honda Pilot middle seat in the second row!

Anonymous

This seat is almost 3” narrower than my Safety 1st seat that it replaced. I was trying to find something narrow enough to fit in the center seat of my 2016 Honda Pilot and that was easy to pull the harness strap tight and this seat is perfect. I have an evenflo dual ride shyft, this graco seat, and a graco backless booster all in my second row and everyone fits just right. My favorite part though is how easy it is to tighten the straps. The seat it replaced never felt tight enough despite strong arming it every time. I’ll be getting another once my infant is out of the infant seat.

Easy to install, comfortable.

Mike Sss

Very easy to install, move around, even travel with. Great that it grows with the kid.

Very satisfied

Reasonably priced, excellent quality, slim fit is just what we needed Bob

Little Traveler's Seat

My young boy really seems to enjoy it, I also like the way when he falls asleep his head does not go forward, instead it goes towards the side.

Comfortable and versatile

Brianna_bellew

I love how many different options you have with this car seat. It will fit any child for a long time and my child looks so comfortable and relaxed in it!

Easy installation and removal

JasonC2

Easy install and removal, not too heavy, very soft comfy padding, and very secure. Will not disappoint.

Comfy and safe!

Amichelle

The fabric and seat seems very soft, padded and comfy for my little one. It was not too difficult to install and I love that it has cup holders too. Definitely a little more leg room on my extend to fit but not cramped at 1.5 years.

Perfect Car seat for Grandma

Gaga B

I am a grandma and purchased this car seat to be able to transport my grandchild as needed. It is extremely easy to install and remove from my vehicle. My grandchild seems to be very comfortable in the seat and I have no safety concerns.

Toddler’s head tilted & chin was touching chest!!

PepeNoah

First of all. I LOVED how slim & compact it is & that it is easy to install. Loved the removable cupholders also. HOWEVER, my toddler's head tilted forward when she fell asleep & her neck literally bent down (chin touching chest). I tried adjusting her head and it was so unsafe. I had it for not even a week & returned it to purchase and E2Fit 3-in-1 (which we had one & is a favorite in our book).

Slim indeed

Bobba27

This is our second time purchasing this model, and it continues to work great. Fairly easy to install, comfortable for our child, and we can fit a small adult in between 2 of these carseats in our sedan.

True to claims

Kye R

Bought to fit in my Subaru Crosstrek and they really do fit 3 across. I love that! The detachable cup holders are great, and deep enough to actually hold a cup. They are also lightweight for a car seat, and easy to take in and out of a vehicle. I would definitely purchase again.

Great car seat (though not so great for newborns)

Lilyrose

I bought this 2 years ago for our son. It is a sturdy carseat with a slim profile (which we appreciate in our VW Jetta TDI from 2014). I believe it's in thanks to this seat that we will be able to fit 3 across when our third comes. It's also well padded, and (IMO) way easier to clean and reassemble than our Grao 4Ever DLX slim. I like too that there is mesh on the sides to promote good airflow. Over all, it's a sturdy, well-put-together seat. That being said, be aware that this is not a great newborn seat. Although you can get a good buckle fit, the recline is not ideal in most cars for a newborn.

Kay4x

I regret spending the money on this seat. I’ve used it for three separate kids and all three have severe head slump. 6 year old forward facing, 2 year old forward and rear facing and 9 month old rear facing. Installed correctly with bubble in the correct spot. I put my kids back in chicco seats and they are able to sleep correctly with no head slump. This seat now sits in my closet for a back up seat in case of an accident to hold us over for new ones.

Slim fit!

Phill S

Great product! And excellent customer service! Fits in so many different configurations and three across!

Exactly the Slim, Lightweight Seat We Needed

Hebaish

bought the Graco SlimFit3 LX because I wanted a less bulky car seat, and it completely delivered. At under 17 inches wide, it saves a massive amount of space in the backseat compared to the standard SlimFit, and it was a lifesaver for travel since it’s so light and fully FAA-approved. The only reason I’m giving it 4 stars instead of 5 is that getting a tight rear-facing installation with the seatbelt takes a bit of extra muscle without a built-in lock-off, and the cup holders can be a tight squeeze for wider bottles. Overall, it’s a fantastic choice if you want to trim the fat without losing safety features or comfort.

Great

Mileva

Honestly this car seat is elite, super slim and my toddler loves it and is comfy in it

JUST WHAT I WAS LOOKING FOR!

Anonymous

This slim car seat was for my new great grandson joining his two older sisters in the back seat! It was just what my granddaughter wanted so all three siblings would fit in her vehicle! PERFECT and I saved 20%!

Great!

Compact, but comfortable for the little. Easy to install and buckle.

Absolutely the best car seat I’ve ever had , it’s not bulky its lightweight, easy to install

Reddit users generally recommend the Graco SlimFit3 LX for its narrow width enabling three-across installations in smaller vehicles, though installation difficulty and some design quirks are noted.

positive sentiment100% match

The seat is praised for its slim profile and ability to fit three across, which solves a major pain point for families in smaller cars.

  • Opinions on Graco SlimFit3 LX in a sedan, compared to Extend2Fit

    I have a Mazda 3 sedan and can fit three across with two SlimFit3 LXs and an infant seat. The Extend2Fit is easier to install and more compact front-to-back, but the SlimFit3 LX is the narrowest option for three-across. I find the seat belt install on the LX takes some muscle but is doable.

  • Convertible car seat opinions: Graco SlimFit LX vs 4Ever DLX

    We have the SlimFit3 LX and love it. It's lightweight, easy to install on a plane, and narrow enough for tight spaces. My 3-year-old still fits rear-facing, and we've used it for travel without issues. Compared to the 4Ever, the SlimFit is much better for three-across or smaller cars.

  • Help choosing between Graco SlimFit3 LX and other narrow seats

    I tried installing the SlimFit3 LX in my CR-V and struggled to get it tight with the seat belt. The belt path is smooth but tightening it enough to eliminate movement was tough. Some CPSTs note that it can be a difficult install compared to other Graco models.

  • Stuck between Britax Poplar or Graco SlimFit3 LX

    I'm comparing the Poplar S and the SlimFit3 LX. The LX is 16.5" wide vs Poplar's 17", and the LX is cheaper. However, the Poplar might install easier. Several parents said the LX's installation was finicky, but once in, it was solid. I chose the LX for the slightly narrower width to fit three across.

  • Three car seats in one car with SlimFit3 LX and others

    We have three SlimFit3 LXs in our Ford Explorer and they fit great. We tried the Evenflo Revolve360 Slim but it was too deep front-to-back. The SlimFit3 works better for extended rear-facing beyond 2 years. The only gripe is the shallow crotch buckle, but overall it's a great seat for multiples.

  • Graco SlimFit3 LX in Mazda CX-5, feedback on fit

    I have a CX-5 and can fit two SlimFit3 LXs side-by-side with a backless booster in the middle. The narrow width is key. Installation was a bit of a learning curve with the seat belt, but after a few tries it's secure. I recommend removing the cup holders for a better fit.
