I ordered one of these because one of my coworkers had one and it was pleasant to sit on and felt like it would help. I purchased one and when I got it it was hard as a brick. I asked my coworker if his was the same when he got it and he said no. I tried it for a couple of days and finally contacted LiBa and they said it was defective. So I proceeded to order another because they assured me it was a one time issue. The second one came JUST AS HARD. I tried to soften it by placing weight on it and bending and such but it is still HARD AS A BRICK. DO NOT ORDER ONE OF THESE....YOU WILL BE DISAPPOINTED!
