My chair arrived fully assembled and I used it as soon as I got it out of the box. (My kids Love the box :)). I'm small, and it is a little bit big in all the best ways. So soft and you just sink right in and feel like you're getting a big fluffy hug. My little sons Love it too and often ask me to sit elsewhere so they can sit there together to watch TV. It does not rock when the legs are up. Fine, but we just didn't know till it got here.
