I purchased the seat & back pad as I was suffering from a compressed disk and Lumbar Strain. Both great products. They give ample support while being light weight. I thought they may become warm during use as some memory foam does but surprisingly, they stay cool. With a quick unzip, the covers can be removed to be washed which is a major plus. The pads work well on couches with deep backs as well allowing you the ability to center your feet beneath you before standing. I would recommend both the seat & back pad for those suffering from chronic back pain. ..More
