iComfort Savant EverFeel Firm Twin XL Mattress

Our most popular iComfort® model combines Firm, cushioning comfort with advanced support and is now enhanced with Serta's exclusive EverFeel™ Technology. A layer of our EverCool® Memory Foam works with the Cool Action™ Dual Effects® Gel Memory Foam to gently contour and cradle at the sleep surface. This not only helps relieve pressure build-up, it also helps provide your body with proper and targeted support throughout the night. - See more at: http://www.serta.com/buy-mattress/icomfort-sleep-system#models-tab
