A Premium Comfort Adjustable Mattress

Superior Construction, Quality, and Technology

The Firm Comfort Q4 brings together comfort and adjustable firmness at a lower cost than our Plush and Ultra-Plush Comfort beds.  Unlike the Firm Comfort Q2 and Firm Comfort Q3, The Firm Comfort Q4 includes a 2″ layer of convoluted foam for increased comfort and contouring above the air chambers as well as the support layer of support foam below the chambers. The customizable two-sided system allows for both sides of your mattress to be adjusted through touch screen controllers on both sides of the bed. The Firm Comfort series comes standard with a breathable, diamond white, damask quilted cover that is removable for cleaning and will provide lasting comfort and support.
