This "bean bag" chair material is made of a sturdy microfiber type material. It looks better from far away then up close, but I don't worry at all about the wear.
Some reviews complain about the foam....and yes, its a chunks of foam "bean bag" chair, not those little styrofoam balls. You can not feel the chunks. You just feel like you are sitting on foam. They are very similar to the LuvSack. I personally find it very comfortable!
The size is large, and can easily fit two 250lb adults on it, even in the sitting position.
The picture is slightly misleading....the only way you can "sit up" on this chair, is if you have it against something (a wall, a couch, etc).
The instructions say that they specifically take off the zipper handle, BUT if you want to open it, you can attach a paperclip.
It does have a lot of static, so lint does stick to it pretty easily, that would be my only complaint.
This was our third FufSack. I think they are a great value, and the size is right for the price!
