If they have decent head control, they can sit in it whenever. See siggy pic! The back is high enough that it gives a lot of support. DD won't sit it in for very long right now though. They are hilarious!
just be careful. One of my gf's sons got reflux from leaning his tummy against the middle part of it.
I had the same thing happen to a friend! Also, putting them in there too early can mess with their spine develpment. Same as putting them in jumpers and excersaucers too early.
