It weighs just over 9 pounds, features 1-click LATCH installation, an adjustable head pillow and harness, and a removable dishwasher-safe cup holder. The seat uses PureCosi™ fabric made without added fire retardants and EcoCare 100% recycled materials; some users note the harness adjuster can be stiff and the seat may be best suited for compact travel rather than everyday use.","url":"https://kidsy.co/products/new-maxi-cosi-romi-2-in-1-convertible-car-seat-sea-shadow","brand":"Maxi-Cosi","condition":"new","product_category":"Baby & Toddler > Baby Transport > Baby & Toddler Car Seats > Convertible Car Seats","material":"EcoCare fabric (100% recycled polyester), PureCosi™ fabric","weight":"9","item_weight_unit":"lb","age_group":"infant","image_url":"https://cdn.shopify.com/s/files/1/0805/9325/6728/files/new-maxi-cosi-romi-2-in-1-convertible-car-seat-sea-shadow-9693683.jpg?v=1775621156","additional_image_urls":[],"images":[{"id":"img-1783485471439-0","url":"https://cdn.shopify.com/s/files/1/0805/9325/6728/files/new-maxi-cosi-romi-2-in-1-convertible-car-seat-sea-shadow-9693683.jpg?v=1775621156","width":832,"height":832,"alt_text":"New Maxi-Cosi Romi 2-in-1 Convertible Car Seat (Sea Shadow) product image (primary)","position":1,"attributes":{"mood":["neutral","calm","safe"],"text":"WARNING.

I really liked that this carseat was ultra light for travel but the installation is actually pretty difficult and the seat does not seem to sit very 'secure' once installed in the vehicle. The chest clip does not stay in place at all & the straps are much too short/tight with little room for adjustment. Overall I am not loving this car seat for my little one.","reviewer_name":"Syd"},{"date":"2 years ago","title":"Decent product but not perfect","rating":3,"content":"This product was provided to me for free for a review. I'm the person who does hours of research prior to purchasing a new seat. For a budget friendly seat this seat meets most of my important items. It does seem slightly flimsy and i struggle to get it snug in the seat. Weight and height restrictions are comparable to other brands. It is very light weight which if nice if you plan to move it often. Overall i would recommend if the friend needed a budget friendly option.","reviewer_name":"Dlprh3"},{"date":"2 years ago","title":"The straps for the car seat is horrible for  my son","rating":1,"content":"I would not purchase if I haven't realized that the straps are too tight! You cannot make them stretch longer. Great price for a maxi cosi! But not worth the money! My son legs are so squeezed tight within the buckle that it makes him so uncomfortable to be in! Please do not purchase! Not great for any child.","reviewer_name":"Moe"},{"date":"2 years ago","title":"Perfect travel companion","rating":5,"content":"We were kind of annoyed lugging around a 20lb car seat every time we traveled. But then we discovered the Romi. This super lightweight car seat is perfect for traveling families who fly. Easy to carry and comfortable enough to get from the airport to your destination without any discomfort to you or your little one. The seat is also approved for airline use so you can be assured that there will be no problem bringing it aboard.","reviewer_name":"DJ_intrinsic"},{"date":"2 years ago","title":"So tight on the legs","rating":1,"content":"it is does not work for our son whatsoever. He is not a big kid, and the straps on his legs are so tight that they bruise him. We have tried adjusting it in so many different ways and ultimately cannot get him comfortable. I think it is due to the buckle being so far back and not having any slack. Anyway, I do not recommend this product. There is no way it can fit a 40 lbs child if it doesn't fit my 27 lbs son.","reviewer_name":"Kk"},{"date":"2 years ago","title":"Very light but comfortable!","rating":5,"content":"I received the Romi Convertible Car Seat in exchange for my honest review. I like that this car seat had no bright prints or characters on it. The black looks sleek. The seat isn't overly padded but my child is comfortable in it for even long rides. This car seat is excellent for travel since it is so light weight. It was easy to bring through the airport. Install in the car is simple too.","reviewer_name":"Chelsea D"},{"date":"2 years ago","title":"The Perfect Travel Companion, Wonderfully Simple Carseat","rating":5,"content":"This carseat doesn't have any fancy bells and whistles because It's not overly complicated, it's perfectly simple. Fast and easy to install (forward or rear facing), it's a great carseat to have for travel or switching cars a lot. It's the lightest carseat I've ever seen, without being $400+ and feeling super flimsy! This honey is sturdy, super easy to clean, feels safe, very affordable and the best travel companion. My toddler dumps food and gets sand all over this and it is so easy to shake off or remove the cover to throw in the wash. Easiest carseat I have ever cleaned! I keep this carseat in my husband's truck, and our \"fancier\" maxi cosi pria in my mini van, but whenever we travel or go in a friend's car we always use the Romi because it's so light weight, more compact than a typical toddler car seat, and easy to transfer/install! About to buy another one for baby #2 because this is the best car seat ever!","reviewer_name":"All hippy dippy"},{"date":"2 years ago","title":"Great convertible seat","rating":5,"content":"We loved this car seat.

It’s soft and comfortable, but not very durable. Which is disappointing since we travel often and I was hoping for something more hard-wearing long term.\nOverall, it’s a great option for travel, but I wouldn’t recommend it as an everyday car seat.","reviewer_name":"Mreis"},{"date":"a year ago","title":"The weight is right but the rest isn't.","rating":2,"content":"I purchased the Romi for a up coming 6 hour flight to Seattle my troller in and for the car rental. Found a good number of reviews that recommended as super light weight and great for traveling. My honest opinion after a solid week of use is I wouldn't use this car seat. Yes, it is very light weight, but the positioning of the opening for the car seat belt is terrible. When in the rear facing position when strapping in my kid, it would dip down. And this was after repositioning the car seat belt a number of times. No confidence it would be in any type of semi fixed position in a crash. The tightening scrap was constantly getting stuck in both directions. If your taking this for a flight, it will more than likely only for in the forward direction, as rear facing the seat is right up against the seat in front. Also, the aircraft seat belt buckle will sit under your childs lower back when tight, not a good feeling. Honestly, I can't recommended the Romi. Yes, it is cheap and light weight, but that's the only good things.","reviewer_name":"Maxxxx179"},{"date":"2 years ago","title":"I wouldn't but for toddler only infant","rating":2,"content":"I'm not able to adjust straps even though it says I can","reviewer_name":"Mom of 11 month old"}],"target_countries":"US","canonical_url":"https://kidsy.co/products/new-maxi-cosi-romi-2-in-1-convertible-car-seat-sea-shadow","reddit_insights":{"match":{"notes":"Threads discuss the Maxi-Cosi Romi travel car seat, its lightweight, flame retardant free fabric, ease of travel, and comparisons.
