The reviews had a an average of 4 stars. Some drawbacks were not enough padding and uncomfortable, while pluses were affordable and a recommendation from Consumer Safety Reports for safety (which is most important anyway, right).

I'm curious how the one mom knew the comfort level...did she sit in it for 45-minutes? Or did her toddler tell her that? Maybe he/she just hates car rides? I dunno, just saying :/
