I suffer from scoliosis and have a hard time sleeping and lying down. The first night sleeping on this mattress was the best sleep Ive had in a long time. I actually overslept and was late getting the kids to school. The mattress is firm enough that it supports my weight and doesn't add extra pressure on my shoulders and lower back. It is very thick and the material on the top of the mattress is very soft. The only con I have with this mattress is that I placed it on top of another mattress, so it constantly slides. If placed on a box spring or a platform bed, this shouldn't be a problem. I used to dread bedtime, but now because of this mattress I'm excited to go to bed now.
