It looks like it could be a pretty nice seat. I had to search to find the height limit, which is 35" (in the comments section of this link).

I have super tall kids, so DD1 was 35" at 18 months. DD2 was around 22 months. It seems like it might actually last most kids up to age 2.
I can't find the actual weight of the seat anywhere. Is it comparable to the Snugride 35?
