Viscofoam has a ball rebound resilience value of less than 20%, as compared to 35% of Conventional Foam. Viscofoam is ideal for body contact products as it provides an even pressure distribution, assisting the flow of blood & significantly reducing the risk of pressure sores whilst greatly increasing comfort levels. Slow Recovery Foam was initially developed by NASA for astronauts, to negate the effects of loss of gravity, while in space.
