Sealy® foam mattresses use a combination of advanced gel and gel memory foams to deliver custom body-hugging support for every part of your body. The carefully layered foams conform to your shape, distributing your weight evenly to relieve pressure points so you wake up feeling refreshed. An upgrade in cooling comfort, the Lacey mattress features a thicker layer of ComfortSense™ Premium Memory Foam, layered with breathable gel foams to deliver body-hugging support. The soft knit cover with SealyChill™ is cool to the touch, while Surface-Guard Technology™ keeps the mattress protected. Available in a Soft or Firm feel.
