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.

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

Trying to figure out the least bulky way to move our 5 year old from his 5 point harness to booster was harder than I expected. I wanted versatility and ease and this cosco backless booster hit the spot! Able to fit 3 seats across in the car and transfer to van with ease. Simple easily and non-complicated

Lightweight and compact

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 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.

Even though our youngest is outgrowing his carseat quickly, we knew that we still wanted something for him to use while in our van. The Cosco Kids Topside Booster Car Seat is lightweight enough that youre not hauling a heavy item from car to car if needed. It gives more "width" to our child while using the seatbelts, a concern of ours since our youngest is on the slimmer side and I for some reason (mommy anxiety) I always think he might slip out of his seatbelt if we were involved in some sort of accident. There are a few things that I think could use improvement: cushioning and density. The padding on the booster is not that thick - I could knock on the seat and immediately feel and hear the plastic shell underneath. Granted I like that its lightweight, but the base is hallow. Im not sure how thick the shell is, but by the sound of it, I could only guess that its pretty thin. Its easy enough to use and a good back up for when going to grandparents house.

Lightweight and portable

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!

This is a good economical seat. It is very light weight and easy to use. I would say the size is more compact than others out there so it could be a pro for a smaller back seat. My son is on the bigger side for his age and did not have any complaints. There are no cup holders which is a bummer but not a deal breaker.

Easy, light weight and economical
