Features

All Beautyrest Harmony mattresses are made with Seaqual Fabric–a sustainable, premium fabric made from recovered ocean plastics. They also feature HeiQ V-Block on the mattress surface which kills 99.9% of bacteria on contact, helping your mattress stay fresh and last long.

The Diamond Series features Micro Diamond Memory Foam–a premium foam infused with diamond particles that helps regulate your temperature throughout the night by conducting heat away from the body.

This line also features advanced pressure relief from high-density, supportive and comfortable foams in conjunction with a precision support system powered by T2 Pocketed Coil Technology.
