I could not get it installed

april

I received this product for free in exchange for my review. I was very excited to try it out with my twins! We loved that it seemed very comfortable and that it has 2 cup holders. I followed the instructions in the book included and could not get the top to stay attached to the bottom. I had 2 other adults attempt to help me and it would not stay together. I searched online for helpful videos and found nothing. I contacted customer service and a week later I have still received no response other than the canned email saying we will respond soon. I cannot recommend this seat because unfortunately we couldn't even use it.

Great lightweight booster combo

KQ

I received the Boost-and-go All-in-one Harness Booster Car Seat in exchange for leaving a review. I was so excited to receive this all in one booster as my daughter still needs the harness, but will soon be transitioning to a traditional high back. I love the versatility of the all in one car seat! It's also much lighter than the other ones we own, which is a major plus. My only dislike is that is is harder to install into the car than other brands we own. However, if you're installing it in one car and leaving it there, this will not be an issue. The color combo is wonderful, a maroon ish purple and tan, just the right neutral. The fabric is also very soft and my daughter loves it. I would recommend to anyone looking for a more light weight combo seat.

Best High-Backed Booster Seat

Mom of Two

After opening the box, we immediately transitioned the forward-facing car seat to a high-backed booster seat for my 6-year-old daughter. Unlike other car seats that I have used in the past, this was super easy to transition and took only a few minutes to complete. My daughter absolutely loves the seat and says that it is the softest and most comfortable seat that she has ever had. The two cup holders are great too as they allow her the ability to have a place for a drink and snack while in the car.

Great seat upgrade

Phyllis

We recently added a new baby to our family and needed another seat for our 5 year old. This was the perfect upgrade. He was already forward facing and ready to transition into a Booster seat. The base is finially small enough that given me room to sit between the two kids. My son loves that his feet hang comfortably and do not make his legs fall asleep. He can easily buckle and unbuckle himself with the car seat belt. I love that I can take out his cup holders to clean them frequently.

Not the best

Not good

This was being used by a 3 year old. From the first time taking it out of the box the back wasn't connected to the base AND wouldn't stay connected

Different design, stiff buckles, comfy seat

Lydia Long

I got this as part of a promotion in exchange for my opinions on it- yay! I picked it for my 4yo who can buckle and unbuckle herself in her car seat. I liked that it turned into a booster seat but didn't realize the top just kind of hooks into the bottom. It doesn't latch in but it still feels secure unless you're moving the seat around. It's cute and looks comfy- typically shoulder straps should be at or above when forward facing and these straps barely go above her shoulders so I'm not sure how much longer she can use it and we are not ready to move to booster yet. She struggled with buckling and unbuckling- they're super stiff and even I had trouble unbuckling her at first but hoping they will loosen up. Overall she loves it- it's cute and looks comfy! The cover for the strap button to loosen and the cup holders come off super easy- we haven't had to wash it yet.

Fantastic economical option for kids seat

norm

At only a little over 100 dollars retail, you can not beat this booster seat. It expands dramatically for a toddler to a 8 year old. Its comfortable, well padded for long drives and isn't so wide. My 5 year old sits happily in his seat and falls asleep on long road trips without his head bending at unnatural angles. It is priced so well, we purchased some for grandparents vehicles also.

A decent car seat

Brianna

I was excited to try this carseat but wasn't super impressed overall. It looks nice, but doesn't feel very sturdy in comparison to my other seats. I also didn't love that even though it is a 5 point harness, a kid can't sit in it until they weigh 30 lbs. the colors are nice and it works for a basic seat!

Comfy, Safe, and Easy to Use

Neenashabeena

We love this seat! My kiddo said that it's very comfy. My husband likes how easy to install it. I like that it's not super bulky, light, and will grow with my child. It's easy to switch from one car to another and from one mode to another. The cup holders are a convenient feature as well.

Overall good product

Mich29

I received this car seat in exchange of a review.The fabric is soft and the seat is lightweight and compact. The cup holders are a plus. I did find it difficult to install and to unbuckle the harness. Overall, I was satisfied with the car seat.

Good quality

Plp

I had an graco forever for my oldest and it was decent. My mild child has outgrown her carseat and we got this one as her replacement. It was ready to install and my daughter loves that she is in her big girl carseat.

Boost and Go - All in one!

CGall

I switched my daughter over to this, and it's been a great change! She fits better size wise; but still has the protection of her prior seat. The cushions are a great add to be able to adjust it as she grows.

Beautiful and Functional!

Kikimarie76

I love that this folds - my husbands truck and the cars that require a seat to fold over rejoice, this solves that issue!! It's soft beauty and easy to clean! So glad we got this - perfect!!

Really nice!!

Twinstatus09

This car seat is really great. It is made well and I can tell that it is a car seat built to last. It seems quiet comfortable and was easy to install

Great quality

Quality car/booster seat!

Samantha Reed

My four year old hopped right into this car seat and said how beautiful, and how much more comfortable they were in this booster seat! You can tell when putting booster/car seat together the quality of the materials used, the padding, the belt buckles, no detail too small. Looks like I bought a luxury booster seat, for a fraction of the cost. Will grow with your child from ages 3-8 if you forward face early based on weight and height requirements. Such a quality investment for my child, and helps give me peace of mind knowing they have a quality product to help protect them in case of any unforeseen accidents.

Great unisex color and super soft

Hmerr

I like the color and how plush the fabric is. It has a five-point harness for added safety and an optional back cushion for extra comfort. I had an older version of this seat and the fabric pilled badly, so I am hoping this one holds up better. It is definitely more attractive and doesn't take much room in my sedan. I did have some trouble with the bottom latches not being able to completely tighten due to a seam on the carseat's strap, so I used the car's seatbelt under tension in addition. It was still a bit looser in the front than I like, but I am used to an infant car seat.

Light weight car seat.

Pchugh1202

We just buy a second car. For our new car we need a car seat. This booster seat works well. It's lighter than the other one and easy to put in place when we need it. It has nice adjustability features, and can accommodate him as he grows.Cup holders? Yep - it's got two of 'em. The material is soft and comfortable. I love how it is so versatile, so it will grow with your child. It is easy to buckle the child in the car seat, and the headrest part moves up and down easily.I like it, the kid likes it too!

The only car seat you need to buy!

Rizz

Thank you Dorel for the Boost and Go all in one car seat. I wish this car seat was around for all of my kids. The car seat is at least half the weight of my previous car seat and as my daughter grows I don't need to continuously buy new seats. It is great that it grows with her. The biggest advantage is the ease of moving between cars and adjusting to other children. As a father of three I highly recommend this product!

BMW of car seats

Kimmykk

Safety 1st US Boost-and-Go All-in-One Harness Booster Car Seat does not compare with others. This is your BAR FAR THE BEST!! HANDS DOWN I was excited to get this car seat! This is BMW of car seat. It was so wonderfully built to comfortably Give your newborn, by cradling them. Up to younger children! our BAR FAR THE BEST!! HAND My 6 week old has hated the car seat from week 1. I tried everything from covering it, to cracking the Windows, music/no music, pacifier, sitting in the back with her... NOTHING worked. So I searched and searched of things to try and came down to getting a different seat. I didn't want to try another infant seat and waste money so I decided I would try a convertible one knowing that she would eventually use it anyway as she grows. It was fairly easy to install I used the seat belt and hooked the latch system as well just because I'm a crazy mom like that (this is my first baby) i have a 2011 Toyota Corolla I did have to move the passenger seat forward to make sure the car seat was reclined all the way... Once I can go to position 2 there will be plenty of room I believe. Any ways my daughter did a lot better. Where as when I wouldn't make it more than maybe 5-10 mins away without her screaming we made it pretty far before she got fussy and even then it was for about 10 mins And she passed out. Before she would cry for 30 mins + and I would Have to pull over to calm her down. I think she likes that she can see outside more being up a little higher and the sea

Seamless Safety and Comfort in Every Journey

Ner Sam

I recently received the Safety 1st Boost and Go All-in-One Harness Booster Car Seat, and it has been a game-changer for our family. I was initially drawn to its promise of versatility, and it has exceeded my expectations. As a parent, the ability to seamlessly transition from a harness to a booster seat without sacrificing safety is a feature I never knew I needed until now. The safety features offered by the Boost and Go provide unparalleled peace of mind. The secure harness system and side-impact protection make me confident that my child is in good hands, or rather, in a good seat, every time we hit the road. Long journeys have become much more enjoyable for my little one. The thoughtful design and adjustable features ensure a comfortable and snug fit. The customizable headrest and harness adapt effortlessly to my child's growing needs, making every ride a joy. One of the standout features for me is the ease of installation. The latch system and clear instructions make securing the car seat a quick and hassle-free process. It's a relief to have a car seat that's not only safe but also user-friendly. I can confidently say that the Safety 1st Boost and Go is a must-have for any parent on the lookout for a reliable and versatile car seat. Its seamless transitions, safety features, and comfort make it a standout in the market. My recent purchase has truly made a positive impact on our family's daily adventures. If you're in the market for a car seat that goes beyond the basics, providing safety, comfort, and adaptability, the Safety 1st Boost and Go is the perfect choice. I highly recommend it to fellow parents looking for a hassle-free and enjoyable travel experience with their little ones.

Light & Easy to Install

Anonymous

My Boost-and-Go Essential 3-in-1 Booster Car Seat is my new go-to travel car seat. It's light, quick to install, and easy to clean. I can easily move it from car to car, and drop it with the grandparents. I love that it will grow with my child and can adjust to 3 different modes. It's a great one time, affordable investment. We'll see how it holds up over time, but seems comfortable and safe! I received this booster from the Stellar Product Testing Panel.

All in one booster seat - amazing

Anonymous

This was one of those items that I never thought I would be excited for, but here I am. I am so ready to move at least one of my kids out of a traditional car seat. I love that the Boost and Go is all-in-one. It has a 5-point harness that will make the transition from super big car seat to booster seat a little less scary (for me). I particularly love the color, because it will hide stains from normal wear and tear.

Wonderful car seat

Anonymous

I love that this car seat has so much range for age. It stylish and comfortable. Easy to install. Right now my child is using it as a high back booster and it is perfect with great cup holders. It keeps his head in the right position when he falls asleep.

The booster is ok

Anonymous

I received the Safety 1st US Boost-and-Go All-in-One Harness Booster Car Seat for free to review through the BzzAgent sampling program. Thank you for that. I have used this booster for a week and it is my first booster car seat that is used for my son. My first impression is the booster's color is very nice and clean. It is easy to set up in the car. It has 2 cup holders that is very convenience to put the drink or snacks for my son. They are removable so we can take them out to clean or wash. The seat is soft and quite comfortable to sit on for a long journey. The headrest can be adjustable to fit with the kid's outgrowth . Especially, the booster can be converted to the backless one when the kid grows up. However, and the most important thing is that I do not like the harness buckle, it is very hard to open although I use all of my strength to press the buckle. Most of the time, I could not open it and my husband just could open it after struggling with it for 5-10 minutes. If we were in an emergency, I could not imagine what would happen if I could not open the buckle to take my son out. So inspite of the pros of this booster, I do not use it anymore.

Comfortable forward facing booster

Anonymous

Safety1st sent me this free car seat in exchange for my honest review. I have an older child who is in a forward facing high-back booster so we were not able to use this seat as a forward facing harness. My child really likes this high-back booster more than her old seat because it has arm rests and the cup holders are bigger than her old one. She also says the seat is comfortable. Once it was in the car, I didn't have to do anything else to it so installation was very easy. I like that the headrest was easy to adjust and that the cup holders are dishwasher safe. Also, it is very lightweight so it is easy to move if we need to use in a grandparent's car. The button to unlatch the harness at the crotch was incredibly hard to push so I'm glad I don't have to use that every day. The instructions on how to remove the harness were lacking, and the only way I could see to do it meant that it would be incredibly difficult to put back together if I ever needed this seat for another child. Also, the seat arrived with the back detached. I put it back together as the instructions stated however the back kept falling off. Overall, we will continue to use this booster seat for years to come as it can be used in multiple modes.

long-lasting, reasonably priced car seat.

JennieLl

At four years old, my daughter weighs thirty-seven pounds. We used the forward-facing harness booster mode while using these carseats. She felt comfortable and thrilled with her new carseat. For comfort, I wish there had been a bit more cushioning on the seat. This carseat was simple to install. I appreciate how the seat can quickly switch between modes and grows with your child. This seat is lightweight and portable between cars with ease. The seat's relative slimness is also a big plus.Overall, we're very pleased with it, and I'd suggest it to anyone searching for a long-lasting, reasonably priced carseat.

Low Profile Great for Bigger Kiddos

Momma of 6

I have 6 children, 5 of whom still use car seats. This seat was versatile enough for my 38lb 5yr old and accommodated my 9 yr old perfectly as well. While it was great for 4 of my children, I would not feel confident putting the youngest (3) into this seat on a daily basis. The way in which the back attaches to the seat is simple but it is also not very durable. The double click never feels secure. Overall this car seat is worth the purchase price. It will get plenty of use by the bigger kiddos! I would recommend this seat to anyone with a preschooler needing a booster.

Easy to use, comfortable

Aprilm1987

I really liek this boost and go all in one harness booster seat. It was easy to snap together. The harness adjusts super easy. The seat is very nicely padded. My daughter said it was very comfortable. I like that it has 2 cupholders. Very easy to install.

Very hard to unbuckle!

alyjh

With a 5 year old that is about to transition to a booster car seat, I've been eager to convert her current car seat to that mode. This was made easy with Safety 1st Boost-and-Go All-in-One Harness Booster Car Seat! I first tried the 5 point harness but my daughter had a difficult time unbuckling herself without any help. Even I had difficulty pressing the bottom buckle to get my daughter out! This won't work with the quick drop off's to school in the morning. I moved the car seat to a booster mode, and that made it a lot easier for her to use. Installation was very easy, which cannot be said about many car seats. However, the cushioning feels thin and my daughter said the seat did not feel comfortable to her for long trips. For the 10 minute car ride to school and back this car seat is really nice to have but for longer trips, I would not use it. Safety 1st US kindly gave me this Boost-and-Go All-in-One Harness Booster Car Seat for free so that I could review it.

A Solid Budget Booster Seat

Anonymous

**I received this booster seat for free in exchange for my honest review** The pros: -it is neutral in color and would work great with any car and any gender -it has deep and well positioned cup holders that are easy for my child to use -it feels safe for my child to use -the material is soft -my child is comfortable in it The cons: -it feels somewhat cheaply made in comparison to the leading booster seats that I normally use -the material feels too loose on the seat -the instructions leave a lot to be desired so initial set up is tedious All in all I believe this booster seat is safe and that kids will like it. I think if you're looking for a budget booster or if you're not interested in a booster with all the bells and whistles this one will definitely fit your needs!

Light weight & great size

Anonymous

If you need 3 car seats in the back row of your car this one will be perfectly fit. It's thin and doesn't take much space, my kids can reach the buckle and fasten themselves. It's lightweight therefore it's easy to move in and out. The cup holders are a bit small.

Slim and compact!

Anonymous

Love that it is so slim and compact. I can see it fitting 3 in a row easily. Compared to our Maxi Cosi, it took up a lot less space. The seat is light weight. The fabric is soft. I like the smooth operation of the straps. It will last us a long time! It came as 2 pieces, with booster and back not attached. When I tried to connect them, I didn't get a satisfying click even though I tried a few times and followed the manual. The installation straps do not lay completely flat on the carseat which makes me a little uncomfortable. There's also no safety mechanism/lock to keep the installation seat belt extra snug like my other carseats.

Skip this product and buy a better quality one

Notaregularmom

We received this booster seat for free from Safety First in exchange for our honest review. This is the fourth brand of car seat that we have owned between our two kids who are four and under but it was our first booster seat only style. When we installed it we found it difficult to use the anchor system and even after tightening as tight as we could, it slid around too much for our comfort. This made me question whether it would fully protect my child in an accident. The quality of the booster seat is noticeably cheap. The head cushion and seat cushion are sufficient but the arm rests are just plastic with a thin cloth covering it. It does seem easy to switch from one car to another and for us, one size child to another with an easy to adjust head rest and harness strap. After installing and using for a few days, we will only ever use this booster seat as a back up product.

Perfect investment for your growing child!

Anonymous

The Safety 1st US Boost-and-Go All-in-One Harness Booster Car Seat is a well made, comfortable, and safe seat. I received this booster for free from Safety 1st as a part of Bzzagent Testing Panel in exchange for my honest review. I personally love the fact that this is a seat that grows with your child. Its a one time, affordable investment as It features 3 different seating options. Forward facing harness is recommended for children 30-65lbs. High-back belt-positioning booster and backless booster is recommended for children 40-100lbs. It is easily converted, from one seat to the next as your child grows. This seat is not to heavy, and my child feels safe. As her parent, I feel she is safe in this seat. ​The head rest is easily adjustable with one hand you can pull it up and down. It features 2 cupholders, padded armrests, and washer and dryer safe seat pads. I have three daughters in car seats and I could fit 3 of these comfortably in my backseat, with most other car seats its a very tight squeeze. It was one of the easiest car seats ive installed. The cup holders twist on and off making it very easy to clean. My daughter got in her seat and buckled herself up, she did need some assistance getting it unbuckled. I dont mind helping unbuckle, that just ensures me she cannot get out of her seat while we're driving. Its very nice, clean and sleek looking. Overall this is a safe, durable car seat that I wouldn't hesitate to buy. I love that it grows with my child, it's comfortable when she falls asleep in the car, she can bring a drink with her, it's not big and bulky, I would purchase more for my other kids. Definitely recommend! You will not be disappointed.

Great, Lightweight Booster Seat

Happy mamma

I was so impressed with how light this seat was when we took it south of the box. It was easy to install and my son was excited to sit in his new booster seat. It has a slim design so you can fit three across in the backseat of a car. The padding was comfortable and soft. I received this product for free in exchange for writing a review.

AWESOME!
