Description

Relieve pressure points as you rest with the targeted support of Beautyrest’s Harmony Coastal Medium Firm Mattress, maintaining an ideal sleep temperature throughout the night. Sustainable, cooling, and comforting, a luxurious Seaqual™ fabric cover promotes cleaner oceans, while the innovative NaturalCool™ cover with Tencel® yarn keeps the mattress fresh and cool at the surface. Flawlessly contouring to your body— AirCool® foam, plush comfort foam, and gel memory foam alleviate pressure-induced aches and pains, allow high airflow, and exceptional breathability. The T1 Pocketed Coil® innerspring unit and foam encased perimeter stabilize the sleep surface to each edge and ensure that your body receives proper support at the center where it’s needed most.
