Designed exclusively for Rooms To Go, the Harmony Glen mattress is ideal for anyone who enjoys a firmer sleep surface and doesn't want to choose between the advantages of a traditional innerspring and premium gel memory foam technology. Featuring an advanced Smart Response pocketed coil innerspring system designed to promote proper sleeping posture, this mattress moves with your body to ensure that you're supported throughout the night. AirCool memory foam with GelTouch enhances the support of the innerspring system, conforming to your body to deliver superior pressure point relief while pulling excess body heat away from the mattress for a cooler night's sleep. Together, the Harmony Glen's advanced pocketed coils and premium memory foams create a firm, supportive sleep environment that works to replenish your body during the night so that you can wake feeling restored and rejuvenated. 10 Year Warranty.
