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