A PRESSURE RELIEVING MATTRESS

摘要

This invention relates to mattresses, such as pressure mattresses comprising a base portion 11a and an upper portion 11b overlying the base portion and having an interface 11 c between the portions which has a coefficient of friction low enough such that the portions can slide relative to each other. This enables relative movement of the portions, when the mattress is lying on a profiling bed and the bed is being profiled.
