This 6" firm mattress has a tight top and a low-motion transfer, so it stays in place even if your partner tosses and turns. It features multiple layers of supportive memory foam as well as a gel-infused top layer that helps regulate temperature and keeps you cool throughout the night. Wrapped in a breathable polyester cover, the surface feels soft and smooth to the touch. We love that this mattress arrives in a compact box for easy transport and expands quickly, so you can start sleeping comfortably right away.
