This plush latex mattress blends a 3-layer Serenity core with a Harmony topper to reach a total height of 13 inches. The top soft layer sits in its own organic casing, creating an extra-luxurious surface and making it particularly appealing to side sleepers who want gentle contouring and pressure relief without sacrificing overall support. The combination delivers a plush, pressure-relieving feel with breathable performance for everyday comfort.

It features four 3-inch layers—Dunlop-based Serenity core plus a Talalay topper—that can be customized by layer and by side for Queen and King sizes. The zippered outer cover is 100% certified organic cotton, with a wool flame barrier for safety. Easy to set up, it includes a 90-day layer-exchange policy and a 20-year warranty. Designed for versatile foundations, it can be used with adjustable bases and should be paired with a solid foundation if not using a base built for this system.
