I stood on the wooden area and it broke some, but the item's still usable. For context, I'm 5'5 and 130lbs and can comfortably fit on this thing for sleep. The back section is made of wood and has very little padding. There are two different kinds of stuffing in the other panels. The hard wooden edge requires me to use a pad on top. 
Side note: the pillow is AWESOME and is my favourite part of the whole item.
