Visco elastic sponge has been developed to compensate for the pressure on the spine. This technology was discovered by NASA for astronauts. Formulated with body heat and weight, visco contributes to healthy blood circulation by supporting the spine perfectly.
HR Sponge has high density and high resistance. Thanks to these properties, HR Sponge which is used as a thick layer under Visco provides balanced distribution of body weight to the surface. It is the only sponge structure that provides an ideal environment for a quiet sleep.
