Experience support for more than just your body with the Harmony Collection. Innovative materials work harmoniously to bring you restorative sleep with improved support, advanced motion isolation and a lush cover made from plastic bottles diverted from the ocean. The Precision Support System™ offers consistent support across the entire mattress, from head to toe, so you and your partner sleep undisturbed. Up to 50 plastic bottles collected by hand from coastlines and ocean-bound waterways* have been transformed into premium fabric to create a lush, durable sleep surface that helps contribute to cleaner water. A breathable, moisture-wicking fabric helps you sleep comfortably throughout the night. Pressure-relieving foams help ease aches and pains while also creating airflow throughout the mattress. Step-ups feature the additional cooling comfort of Infinicool® and premium foams for enhanced pressure relief. All models are crafted with a lofty, quilted top, making them perfect for those who prefer a lifted feel and want rejuvenating sleep each and every night. *Collected from areas within 50km of coastlines. Plastic bottles collected vary by model ranging from 30 to 50.
