Bought the Extra Thick Bamboo Mattress Pad - Removable Pillow Top to go with our new Sleep Number mattress based on a recommendation found on another site. It was definitely worth the money spent. Although the new mattress is comfortable the pad takes it to another level. It fits well on our mattress and provides another layer of cushioning. Plus, it doesn't trap heat as many others do. We are very pleased with this topper!
