Four inches of hotel bed, built on top of the one you already own. A firm mattress is a different problem from a sagging one, and it needs a different answer. Most plush toppers solve it by being soft the whole way through — which feels wonderful for a week and then lets you settle onto the same hard surface you were trying to escape.
The Hybrid's ComfortFusion technology is two layers doing two different jobs. On top, a quilted pillow-top carrying 470 GSM of fill — nearly twice what other hybrid toppers hold. Underneath, two or three inches of gel-infused memory foam that doesn't give way. Plush where you feel it. Structure where you need it.
