Cal King Beautyrest Harmony Cayman Plush Mattress

The Beautyrest Harmony Cayman Plush Mattress is a plush yet supportive mattress that provides sustainable comfort and cooling technologies that work together to deliver a comfortable, restful sleep.

All mattresses in the Beautyrest Harmony collection feature a SEAQUAL Sustainable Fabric Cover. By partnering with SEAQUAL, a leader in ocean plastic recovery and up-cycling, this mattress helps promote cleaner oceans and sustainable materials (recovering the equivalent of up to 25 water bottles from the ocean for each mattress!). The cover also features integrated HeiQ V-Block antimicrobial technology that attracts, breaks down and eliminates bacteria on contact maintaining both the appearance and lifespan of your mattress.

The targeted support system is powered by T1 Pocketed Coil technology that offers support where your body needs it most and adapts to different levels of compression. New NaturalCool features TENCEL fabric that keeps your mattress fresh and cool by wicking away moisture.

The AirFeel Foam that lies at the surface provides airflow with an open cell structure. The Charcoal Infused Memory Foam works alongside multiple luxurious foam layers for personalized comfort and advanced pressure relief as well as natural temperature regulation. The AirCool foam allows for additional advanced airflow providing further temperature regulation and a cool sleep throughout the night.

This mattress features plush premium foams just beneath the surface, so if you are looking for a plush mattress that supports sustainable initiatives, provides advanced temperature regulation, and features innovative support and comfort then you will love the Beautyrest Harmony Cayman Plush Mattress!
