Advanced comfort technologies include a new carbon fiber foam for consistent support, gel memory foam directly below the quilted sleep surface for immediate pressure relief, and a premium memory foam featuring actual diamond particles to help conduct heat away from the body. Plus, each mattress includes a suite of cooling technologies to help you fall asleep and stay asleep.Beautyrest is also partnering with Seaqual™ to offer their unique sustainable fabric technologies within each Beautyrest Harmony Lux mattress. Seaqual is the leader in ocean plastic recovery and upcycling efforts, and together this partnership will help promote cleaner oceans with every mattress sold.
