Memory foam, also referred to as visco-elastic foam, is a material known for its superior pressure relieving quality, which helps reduce tossing and turning. Customers generally like the idea of memory foam being supportive, pressure relieving, durable, resistant to bacteria, mold, mildew, and mites. It reduces motion transfer across the mattress and provides the signature molding/melting feel. Higher quality products made from high-density foam from at least 5lb/ft3 are significantly heavier; they are typically firmer, and more durable with shorter response time – faster recovery to its original shape.

Memory foam doesn’t breathe well and some customers find it hot. For some it is also difficult to turn around in it and there are numerous complaints about outgassing of the new mattresses causing respiratory irritation. High-density memory foam is not ideal for small children and adults with lower body weight, since their weight doesn’t’ allow for proper foam depression. Less expensive products will by substantially thinner, generally made from only two layers – regular polyurethane foam support layer or support core and thin layer of memory foam (1-2” only)
