The perfect compromise for those who enjoy benefits of both traditional innerspring and memory foam mattresses, the TEMPUR-Flex Prima fuses the best of both designs to create a supremely adaptive mattress with a firm, supportive feel. Starting with a Dynamic Response layer, made up of densely packed precision coils engineered to actively react to your body's movement, this mattress delivers highly responsive, targeted support. A layer of TEMPUR-Response material enhances the adaptive qualities, providing body-contouring comfort with a springy feel. TEMPUR-ES material at the sleep surface offers the adaptive, pressure point relieving comfort that TEMPUR-pedic is known for, while the integrated SmartClimate system wicks away excess body heat and moisture to maintain a cool, comfortable sleep surface that will keep you sleeping soundly and allow you to wake feeling refreshed. 10 Year Warranty.
