But I use it as one of a pair of mattress toppers. I had back pain, lousy sleep, etc . but I just bought a new mattress and I didn't want to try to return it. I bought a decent king-sized mattress topper and it helped. Then I bought this one and use both toppers at the same time. It's awesome. Frankly, sleep is extremely important, so it's worth spending a little money. If I had to do it over again, I'd buy TWO of these and put one one top of the other. The loops on the corners and a fitted sheet will keep them in place. Its a bit extreme, but you will sink into softness and sleep better than you had before, a lot better. Just do it.
