Ease Of Use

Simple to use and adjust, even for specific features.

Simple to switch vehicles with easy seat belt installation.

I have a five year old that has been refusing to sit in his bigger car seat, this is perfect for him it's less bulky and makes him feel like a big boy while still keeping him safe. Super light weight too. I like the esthetic it goes well with my black interior.

Exactly what I needed

Cosco Kids

This booster seat is great. It's a great size and it's lightweight. It was very easy to install and makes it very easy for my child to get in and out and buckle themselves in. I would definitely recommend for anyone with a child outgrowing a full car seat.

Very comfortable and functional!

We used this for our 7 year old who hates car seats. This one he actually enjoyed. The padding was great and he found it very comfortable. In the past he would fight us on riding in a booster but this one he actually liked. He was able to see out the window which he generally complains about not being able to do. All in all a great booster and would use this for our other children. My son was getting out of the car when I took the pic so didn't have chest belt on, but it sits right where it needs too with the booster.

I would definitely buy this product again.

This booster seat is extremely lightweight and easy to switch from car to car. The fabric is nice and provides enough padding to keep my little one comfortable. It comes in a variety of stylish shades. Easy to install, easy to clean, and keeps my child safe. . . what more could I ask for. Thank you Cosco.

Lightweight and convenient

Great for children over 5 years old as well! Love the neutral colors. Easy to install. Actually, VERY easy to install. Keeps you legal on the road and the kids safe!  I was surprised how simple it was to use and the perfect high for seatbelt adjustment.

Amazing product

I received the car seat booster for free and I had to leave an honest review. This car seat booster was easy to install. It's being using by my 8 year old who weights 52 lbs. She fits there comfortably and said that it's comfortable to sit in it for hours. We took a long trip and she was not complaining that's for sure. I'd say it's com-probable to other brands. I'd definitely recommend it to others if you are in the market for a good booster car seat for your child.

Great Booster Car Seat!!

I really do enjoy the ease of this si.ple booster seat. It's super easy to install and super easy to use. UT grows with your child and I like the fact that I can swap it out to different vehicles with ease. Very comfortable material and stains cam be wiped away very easily. Will definitely be using this for years to come when my younger children need a booster seat.

Super easy to install. Very easy to use.

I really like how light this booster seat is.  It will be great for taking on an airplane and traveling with.  It isn't super padded - but again, it will be great for traveling.  The one bummer was that the manufacturer date was July 2022, so as of November 2023, we have lost out on over a year of use of this seat.

Lightweight booster

*I got the product for free in exchange for writing the review.* I really love how this booster seat is light weight and easy to use. It's also very convenient to move from car to car. I do believe it is best for kids that are a little older and have outgrown their 5 point harness car seats but are still too small for a seat belt alone. Personally I would not put my child who is younger than 6 years old in it because I feel that it can be a little unstable when not enough weight is on it.

Very convenient

Thanks Cosco for kindly sending me this booster seat in exchange for my honest review! This seat is extremely lightweight and budget friendly which make it the perfect option for grandparents, babysitters, and traveling. For our every day seat we prefer a few more bells and whistles like a cup holder and plush padding, but this is the perfect backup seat! However, if you don't desire those extras, want an option that saves more space, or want a great budget item then this seat is perfect for you!

Inexpensive and lightweight making this a perfect backup!

Cosco Kids Topside Backless Booster in black, a lightweight, compact booster car seat with contoured armrests and a smooth, machine-washable fabric cover featuring the Cosco Kids logo, designed for forward-facing children to keep seatbelts properly positioned and car seats unmarked.
