I was expecting a cute little bean bag chair under my bed for my small room, instead I witnessed a Kraken rose from its slumber. I may have underestimated 4 feet because when I open the box, the fluffing was terrifyingly expanding. And when I read the little pamphlet it came with and it says that it should expand for 7-14 days, I was worried. This thing could get bigger I am currently sitting at it and I now understand. I am 411 and I am comfortably sitting. The thing is bigger than my 4x6 ft. rag and pops back to its place as soon as my bottom leaves (lets see how long does the foam hold up to). I am very happy honestly. This is exactly what I need after a long, tiring day. Be careful though, it comes in this unusual chemically smell. This may not be an issue in the coming days. Have fun yall.
