Cosco Topside Booster Car Seat Reviews Summary

Comfort and Design

Pros:

• "They fit great! The kids love them and were actually fighting for the new car seats."
• "This booster seat is perfect for our 10 year old. He's at that age/height where he still wants to sit up a bit higher. This seat helps the seat belt rest properly."
• "I like how it is tapered in the back to better fit the seats in my car and most cars as the seats are not flat but shaped like a butt, it makes it easier to buckle the child up."
• "Love these, my boys have used for two years and just got my daughter one. Fits three across without any issue, fit in my contoured seats, easy to clean (removable cover) and no complaints in comfort ever."
• "These are great! I bought 2 for my kiddos. They are very lightweight and I loved how easy it was to remove and wash covers!!"
• "Very lightweight and slim design is perfect. We have 6 children in car seats and these slimmer designs allow us to fit 3 car seats in a bench more comfortably."
• "This is perfect for my oldest son. He is 10, but still on the small side. He just moved from a high back booster to this. It is small, easy to use, positions him correctly, and is unobtrusive."

Cons:

• "This is hard as a rock. Cushion is only like 1/4 thick. Less when kid sits on it. I don’t recommend this unless you need it just for 5 minutes trips."
• "Purchased for my 6 and 7 yr old daughters--they are about 50 lbs, and mid 50%ile height and weight. The LAP BELT RIDES TOO LOW--on their legs, rather than over hip bones = not safe."
• "I am not happy with this booster. The seat belts sit weird on it, and is not safe how the belt will lay in kids legs and across their chest."
• "This Booster Seat seemed ideal. It was a good price point and not too bulky. The main issue is the lap belt arms that hold the lap belt down are shallow and the lap belt pops up over the arms this makes the seat ineffective and a risk for potential internal bleeding if you were in an accident."
• "I'm surprised this gets so many great reviews. For older kids... this seems like a very narrow and uncomfortable seat."
• "Not good. Small in width, not comfortable and cheap. You get what you pay for on this one."
• "The most uncomfortable booster I have ever purchased. The padding is so thin that my grandchild is miserable sitting on this."

Safety and Security

Pros:

• "This is a basic booster seat for a child who is not quite tall enough for the regular seat-belt shoulder strap. It provides some height as well as side support to keep the child from slipping side to side."
• "I had been searching for months to find booster seats that would fit 3 across in our Honda Accord."
• "The Cosco booster seat fits perfect."
• "These fit great in my 2010 Toyota Highlander and all 3 kids said the seats were very comfortable!"
• "I was having a really hard time finding a booster seat to fit my Scion TC, with the bucket seats in the back."
• "Seats in my Model 3 were too narrow for my kid’s old booster seat but this fits perfectly and doesn’t cover up the seat belt buckle."
• "Easy to install, keeps the seatbelt at the proper height."

Cons:

• "I had to buy 3! No they do not have a LATCH so if no kids are in seats and you have an accident (hopefully never have an accident with such precious cargo) the boosters could possibly slam front seat passengers in back of head."
• "This seat feels cheap. It is not very tall, which made the seat belt cross my kiddos neck dangerously."
• "It’s smaller (the only plus) but it’s hard to use. My 5 year old had a hard time getting the seat belt under the arm. It doesn’t seem that sturdy."
• "No possible way this product should have passed safety regulations."
• "This booster is described as ‘light weight’. That’s it’s problem. WAY TOO LIGHT! My granddaughter was sliding all around the backseat."
• "These are very small and flimsy."
• "Arm rests are so low that you cannot secure even a 40 lb child, much less 100 lbs."

Convenience and Portability

Pros:

• "The product itself seems fine. Light and functional. Smaller than my other booster seat as well which was useful as it's a bit squeezy trying to see at that back of the car with 2 boosters. What I am not happy about though is the state it came in."
• "These are exactly what I was looking for- something light, cheap, and able to fit into a dump truck seat next to built-in tool consoles."
• "simple design, very light to carry. was helpful during our travel to Disney."
• "Exactly what I was looking for in a booster seat! Light weight, easy to use, and so much better than all the bulk of a carseat. Price point was on point too! Bargain and bang for your buck."
• "Very lightweight and convenient. The price made it affordable to but several of these for my different vehicles, convenient."
• "I can carry this after use when I walk around NYC and just pop it in when I need it."
• "This booster seat is small and lightweight. It's easy to store and perfect for when we need to use it last minute as a backup."

Cons:

• "For the price you can't beat it, but there are no frills. You get what you pay for."
• "Great minimalist car booster seat. However, a primary reason to buy such a booster is to have it for traveling on airplanes. Yet, it doesn't have handle or a place to attach to luggage with a hook."
• "Very cheap material. The box said to follow the enclosed instructions. There were none."
• "Cheap and functional. My 5 year old complained that it wasn't comfy."
• "These were purchased to be used in TCs, taxi and extremely light traveling."
• "The quality wasn’t great, and we didn’t feel like it was a good quality for the price."
• "Amazon doesn't have any good just booster seats like this from Graco for girls... This brand is smaller, considerably, and is just not ideal but will do in a pinch."
