Royal Ultime is a multilayered hybrid mattress designed to allow you to enjoy restful sleep while keeping your body at an ideal temperature. It is made of gel infused memory foam and several layers of different types of foam (foam technology). Royal Ultime has an added transition foam layer that is meant to add responsiveness to the multiple layers of foam while significantly supporting your pressure points and enhancing the air flow properties of the mattress. At the base of the mattress, you can find a thick 5-zone pocket spring layer and supportive base foam.
