First off I couldn't believe that something so big fit in such a little box! It comes with the foam already compressed in.  It took awhile to break the clumps apart, and roll it around to speed up the fluffing. And fluffed it did, I thought it was pretty full after I did that, and it looked good. Well, the next day it was sitting taller and looked way more full! Its pretty heavy, but not nearly as heavy as a traditional bean bag chair which is a major plus! I've sat on it, and I'm on the heavier side of weight, and didn't sink to the floor. My kids ages 6-8 love sitting on it, and have lounged across it 2 at a time. I was worried this size would be too small, but it's more than enough space for them at this age and for years to come. Love it!
