Also sometimes referred to as a visco memory foam mattress pad, this bed accessory has the ability to react to your body heat while retaining it at the same time. This attribute is more dominantly associated with high density memory foam mattress pads which react to your body heat by softening while simultaneously conforming to the shape of your body to give it the right amount of support it needs. Heat from bed accessories such as electric blankets can deform the foam’s visco-elastic properties and reduce its moulding abilities, so it is recommended that such products are not used with a mattress pad.
