NEW Improved comfort as we have just replaced our memory foam with GRAPHITE Gel Memory Foam...sleeps cooler, feels better, more natural Medium not to firm not to soft comfort Made in one day so its arrives fresh with no stale chemical smell Made in the USA Our 10-inch mattress, featuring two inches of conforming graphite gel memory foam over six inches of support foam for medium comfort, is wrapped in a white textured eight-way stretch fabric with a luxurious pebble gray border. The next-generation graphite cooling gel is fully immersed throughout the memory foam, making it cooler and more comfortable than foam with only gel-infused beads. The open-cell Visco elastic foam allows air to move freely throughout the mattress, helping to regulate temperature and keeping you more comfortable. The mattress reduces motion transfer as the foam absorbs movement, preventing disturbance to your partner and providing individual support for all sleep positions. Complete with a pre-installed cover, the mattress arrives vacuum-sealed. Once opened, allow one day for the foam to fully expand, with any new foam smell dissipating within a day or two. It is compatible with any box spring, flat platform, or adjustable base and meets or exceeds all 1633 and 1632 fire safety standards. Our mattress, tested and accredited by Certi-PUR US to meet or exceed strict standards for content and emissions, is 100% handmade in America, including the fabric, foam, and labor, with the finished size potentially varying.
