We have developed a new mattress fitted sheet RISAS through a new generation of intelligent fibers. The tissue (Tencel) of these fibers, with induced polyurethane, makes it a superfine membrane.
Tencel is as refreshing as the linen, as warm as wool, as soft as silk, as strong as polyester, and more absorbent than cotton. Those properties makes itself a thermoregulatory fiber, that is, that it keeps the body temperature.
The mattress fitted sheet protector RISAS is waterproof, breathable and it is recommended specially to memory foam and latex mattress.
