This is a great product, especially for someone with a bad back, (such as mine), and who has a very firm mattress. I am, however, old enough that while my firm mattress works great for my back, my shoulders, hips and elbows have begun hurting in the morning. I tried several toppers, all were too soft for my back. This topper however is perfect!...supports my back, but releives the joint pain. And the price is right.
