Minimising peak pressure increases patient comfort and reduces the risk of pressure ulcers. Castellated visco-elastic foam delivers a high degree of pressure reduction as it conforms to the shape of the body. Smaller castellation’s at the heel and shoulders improve redistribution of pressure over bony prominences. The Memaflex high density visco-elastic support surface offers zonal pressure redistribution to reduce peak pressure. Welded seams and a covered zip reduces the risk of fluid ingress.
