Basic polyurethane foam is the most common type of foam used in mattresses and is a staple in bedding material. The low density and soft feel makes for a comfortable addition to bedding that is also cost-effective and economical. Polyfoam also has an open cell structure, conducting heat away from your body with greater efficiency than viscoelastic foam. Basic foam is available in a wide range of firmness values, allowing it to work well with a variety of other mattress supports. This type of foam is ideal for back and stomach sleepers.
Visco memory foam or viscoelastic foam is the term for basic memory foam, which has been around for forty years. It has the same cellular structure as polyurethane foam, but is bolstered with chemicals to give it that “memory effect”. The main benefits of visco foam is the durability, resistance to sagging, no motion transfer, and ability to conform to your body’s shape for optimum spinal alignment.
With all the advantages of viscoelastic memory foam including no motion transfer, softness, and spinal support, gel memory foam has one advantage over regular memory foam, and that is in its cooling technology. Microbeads of gel are infused into the foam, designed to wick away heat and give you the ultimate sleeping environment. Gel memory foam mattresses are often made up of layers of support for a lovely weightless feeling for those who always wondered what it would be like to sleep on a cloud.
