I bought a firm tempurpedic bed a decade ago, and lately have found that my hips were a bit achy, so I began the quest for a topper. I wanted something soft but not so soft that I would sink into it, as I sometimes struggle to move around in very soft memory foam beds. I elected to go with this topper, which has a thick memory foam with a quilted mattress cover and am very happy with it. I get the softness/cushioning I need (no more sore hips) while avoiding the sinking-in trap. The only reason I didn't give it 5 stars is that occasionally the quilted mattress cover portion makes a lump that I have to smooth out. Princess and the pea, I guess ;)
