My husband's hip was hurting while sleeping on our mattress. As the mattress is still fairly new and I don't have any problem with it, I decided to buy this mattress padding on our bed. The mattress topper was wonderful! His hip pain went away after couple of days of sleep on this new topper. One less star as the topper is warm and I feel like I need 2 layers of sheets as my back is sweating after laying down on it for a while. I needed to put oversized mattress pad on top of this mattress topper and then put the sheet to take extra moisture away. Overall, it is a great product.
