Viscoelastic foam is used in memory foam mattresses to relieve pressure points and give contouring support. Memory foam reacts to body heat by shaping to the shape of the sleeper and equally distributes weight. For a more pleasant sleep, this promotes spinal alignment and relieves pressure points. The motion-isolating qualities of memory foam mattresses make them ideal for couples or people who are sensitive to movement. They can provide a soft and firm sleeping surface that conforms to the shape of the body and promotes a comfortable and pleasant night's sleep.
