The CoolX offers cold-touch fabric that delivers cool comfort. Our tagline, "Cool Nights Sleep," embodies the luxurious and refreshing experience our customers enjoy with every rest. We offer three distinct product lines tailored to different sleep types, while maintaining the core Marquis Mattress promise of superior comfort and innovation. Marquis mattress is a different kind of company. We have designed our products from the ground up, using feedback from customers as to what features are most important. We’re different because of the components we use. By sourcing quality Made In America materials you can rest assured that your mattress will maintain its feel and support for many years. At Marquis Mattress we pay attention to the little things, like the way our mattresses look and their fit and finish. Our state-of the art manufacturing equipment and skilled team allows US quality and consistency in every mattress we build. Our mission is to provide our customers with their best night’s sleep. It’s hard to get a great night’s sleep when you feel you’ve overpaid for your mattress, which is why Marquis Mattress offers high quality mattresses at affordable prices. Our CoolX line gives you a choice of plush and medium firmness levels. Both start off with a cool touch cover that provides an initial cooling sensation when you climb into bed. We use layers of cool gel memory foam that draws excess heat away from the body, while providing excellent pressure point relief as well as a luxurious feel. By placing layers of memory foam below the cooling gel layer, it gives the Cool X line additional pressure point relief while supporting your individual body type. Our breathable base layer provides years of support while allowing the cushioning above to gently support your body’s natural curves.
