Upgrade your mattress to the Nectar Classic 5.1 Mattress. RefreshRest cooling and antimicrobial technology is woven into the soft cover. Moisture-wicking, breathable fabric dispels heat and fights bacteria for a fresh and comfortable sleep. 1” of therapeutic gel memory foam provides perfect pressure relief and a responsive contouring feel for soft comfort. 3” of gel foam gives responsive back support and promotes proper spinal alignment. A 8” layer of conventional foam ensures stabilized support and maximum motion isolation for an undisturbed sleep. Lastly, a soft stitchbond cover keeps the inner core of your mattress in place and prevents each of the layers from shifting on top of each other.
