Beautyrest® Harmony features exciting new innovations in support, comfort, and cooling working together in harmony to unlock your best sleep. First, we've developed a new support system that features a patented dual-stage coil design to provide additional support under heavier compression. Positioned within the center of the mattress, this new coil provides additional support where you need it most. We've also introduced new comfort technologies, including a premium memory foam infused with charcoal that provides natural cooling and pressure relief. Each new Harmony mattress also features natural cooling via eco-friendly TENCEL fabric, or step-up to enhanced cooling with cool-to-the-touch technology on select models. Beautyrest has also expanded our partnership with Seaqual™ to offer their unique sustainable fabric technologies within each Beautyrest Harmony mattress. Seaqual is a leader in ocean plastic recovery and upcycling efforts, and together this partnership will help promote cleaner oceans with every mattress sold.
