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 50 km of coastlines. Plastic bottles collected vary by model ranging from 30 to 50. Color: Waves. Material: Polyester Blend.
