Designed using cool blue technology, this topper has the advantage of keeping you cool as you sleep. The member foam cradles you in the same way as regular memory foam however its very low (almost zero) viscoelastic threshold and high reactivity prevent it from completely molding around the sleeper which is the major contributing factor to the excessive warmth associated with sleeping on memory foam mattresses for some people. Available with a soft cover for extra comfort. White Noise Size: Kingsize (5')
