These mattresses feature SLEEPMAKER Pocketed Coil technologies as used by many luxury hotel groups globally such as Marriott, Starwood and Shangri-La to name a few. The innovative SLEEPMAKER Pocketed Coil product delivers not only an exceptional guest sleep experience, but also amazing durability that makes our products truly special. Each coil works independently, contouring to the curve of the body and preventing motion from being transferred from one side of the bed to the other.
