My 12 year old loves these.  They are very versatile.  You can lay on them like a little mattress,  You can sit on them like a chair, and adjust the seat height/back height as you decide where to fold it.  You can place it on a corner and lounge on it in a banana shape seat.  The material is very sturdy but not uncomfortable.  I probably should have given a 5, but I can't ignore the fact that bean bag chairs, in general, tend to look a little untidy.
