Memory foam

Memory foam

We offer a wide range of visco-elastic foams in various densities ranging from 45 kg/m3 to around 80 kg/m3. These qualities are extremely suitable for the production of pillows and mattress top cover plates. VA foams were originally developed for space research to distribute body weight, absorb energy and regulate heat.

The visco-elastic grades have a low temperature sensitivity and offer an optimum pressure distribution on the area of contact at any temperature. This means that our foams maintain their optimum (visco-elastic) characteristic within a wide temperature range. The higher densities have been specially developed for situations where reduction of pressure points on the body, moisture and heat regulation in combination with comfort are of importance. This foam is ideal for medical mattresses and mattress covers.
