Beautyrest Harmony features new innovations in support, comfort, and cooling working together in harmony to unlock your best sleep. First, weâ€™ve developed a Targeted Support System powered by T1 Pocketed Coil Technology designed to offer additional support where your body needs it most. The T1 Pocketed Coil is placed within the center of the mattress to power the new support system. This patented, dual-stage coil design was invented by Beautyrest and provides additional support under heavier compression. In addition, we've introduced new comfort technologies, including a premium memory foam infused with charcoal that provides natural cooling and pressure relief. Choose from breathable and eco-friendly TENCEL fabric, or step-up to enhanced cooling with cool-to-the-touch technology within our Emerald Bay Series.Beautyrest has also expanded our partnership with SEAQUAL to offer their unique sustainable fabric technologies within each BeautyrestÂ® 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.
