Comments: The Cosco Topside is a very simple booster–it’s just a booster. No cup holders, rotating armrests, etc. Walmart sells this seat as well.

While most parent feedback on this seat is positive, dissenters note the utter lack of padding in the seat—so this booster might be best for short trips or very occasional use. Yes it is very lightweight, but it is also smaller than other backless boosters (and hence might not fit larger kids). Rating: B
