After a month of use, we were quite enjoying the seat despite some issues but started to notice our daughter was developing nicks on her feet. It wasn't a major concern until after a 10 minute car ride with a screaming baby we found blood all over the bottom of the seat and were horrified to discover even with socks, she had bashed and scraped her feet against the silver plastic guard on the bottom of the seat while moving her legs causing her heels and ankles to be cut in several places.

She's only a month old and normally a sleepy baby in her car seat. Apparently it doesn't take much for infants to catch their feet on this design flaw. Maybe some babies are more docile with their legs than my daughter, but why chance it? I'm so disgusted with this seat and am returning it promptly.

This car seat is extremely well designed - convenient to install and to carry (and it's compatible with the maxi-cosi stroller adaptors, so fit our stroller easily). At a car seat installation session we went to, the guys working there said of the thousands of car seat fittings they've done, the Aton is their new favorite and by far the easiest to install. Despite being suitable for infants up to 32 pounds, the seat is fairly light and quite convenient to carry, and is compact enough to fit well into smaller cars.

I started my search bylooking for the most lightweight system, and purchased the Graco Snugride. However, this seat was absurdly long and made the passenger seat in front of the seat practically useless (not to mention dangerously close to the airbag). I have since learned that virtually all rear-facing seats have this problem, unless you place the seat in the middle of your vehicle. This is of course not an option if you have two car seats or do not have a middle position.

This seat is only slightly heavier than the Graco and is much better quality. The infant insert is very comfortable and our baby loves to sleep in it for hours outside of the car. The base is really good quality as well and has a interesting device to cinch down the straps that is highly effective.

Another review mentioned that the "Cybex" logo has sharp edges that can cut feet. It does! Thanks to that review I put a strip of packing tape over the logo and traced the outline with a razor to... Read more
