I bought this for my mother for Christmas. She has suffered for years with low back problems. However, after receiving the gift and opening up the box, I was the first one to jump at the chance to try this out. After having stood at the sink washing dishes that could not go into the dishwasher my lower back needed it. This was wonderful. I felt the release of tension immediately. Needless to say, she had to ban me from her present for fear I might try to take it home with me.
