The Sealy Pearl Memory features weight responsive Posturetech springs for total body support with memory foam to correctly support and align the spine. Sealy’s advanced spring system aims to provide the underlying support your body needs for a refreshing nights sleep. Gradually getting firmer as pressure increases, the springs are designed to improve spinal alignment and reduce aches and pains. The Memory foam top is an innovative material designed to shape itself to the contours of your body and then spring back into shape when pressure is released. Memory foam mattresses can offer valuable sleep support in a number of ways, such as enhancing circulation, equalizing pressure to relieve back problems, promote better spinal alignment, and reducing the effect of allergens for a fresher, healthier night’s sleep.
