Revolutionize the way you sleep with this luxurious Serene foam mattress topper. The next generation in comfort, this mattress is engineered with billions of microscopic air capsules that act as individual shock absorbing cushions, releasing air independently as pressure increases. The unique function of the cells consistently lifts and supports your body while reducing pressure on the hip and back areas. The modern design far outperforms traditional mattresses. Zero gravity support reduces energy transfer, so you remain undisturbed by the movements of others. Comfortable and cost efficient, this fantastic foam mattress topper offers a restorative, peaceful night's sleep, night after night.
