The Round Hill 12-inch Queen Hybrid Mattress combines gel memory foam with individually pocketed innersprings for a medium-firm feel. A 7-zone support layer targets pressure relief, while pocket coils limit motion transfer and a breathable cooling layer is meant to sleep cooler than standard foam. It ships compressed in a box and expands over 48 to 72 hours. It suits couples and back or side sleepers who want spring support with a foam comfort layer, though hot sleepers and fans of very soft beds may want to look elsewhere.

This is a 12-inch queen size hybrid mattress that ships compressed in a box. It combines gel memory foam with individually pocketed innersprings and has a medium-firm feel.
A 7-zone ergonomic support system contours to the body's natural curves to relieve pressure on the neck and back. The pocket springs isolate motion, so a partner's movement is less likely to disturb sleep. A reinforced perimeter provides edge-to-edge support and helps prevent sagging and roll-off.
A breathable cooling layer is 30% more breathable than standard memory foam. The mattress is CertiPUR-US and OEKO-TEX certified. It expands fully in 48 to 72 hours after unboxing.
