Peak 12" Hybrid King Mattress

The Ashley Sierra Sleep Peak layers foam and wrapped coils into a medium-feel hybrid that covers the basics well. Quilt foam and luxury loft fiber make up the top comfort layers, with gel memory foam underneath targeting lumbar support. A base foam layer anchors everything, and the individually wrapped coil unit — built with Ashley's Edge perimeter reinforcement — handles support across the full surface while limiting motion transfer from one side of the bed to the other. The 4-way stretch Hyper Cool knit cover is designed to move heat away from the sleep surface, which helps if you tend to run warm at night. Compatible with adjustable bases. Backed by a 10-year non-prorated warranty.
