I wanted this for behind the bed to use as a wedge to not only sit up but also sleep. It's hard as a rock. It's not flat on the end of the wedge so you feel it on the lower back and it's so uncomfortable with your head that you are feeling bricks. It comes to your home folded and in this plastic bag where they suck the air out and when you open the bag, it expands and pops out... IN OTHER WORDS>>> you can't return it. It's absolutely impossible to return this because it's huge, heavy and you cannot shrink it and fold it.. so you are stuck. I dont even know how to throw it out... will be donating it to good will. Very upset with this one. Threw away money... dont buy it.
