Pressure relieving mattress
This invention relates to mattresses such as a pressure relieving mattress and in particular ones for profiling beds. The mattress comprises a base portion 11, a carriage portion 12, an upper portion 13 and an inflatable pressure relieving underlay 14 disposed between the carriage 12 and the upper portion 13. The facing surfaces 15 and 16 of the base portion 11 and the carriage portion 12, respectively, are coated with a low friction material so that the two slide easily relative to one another. This sliding movement is restricted to longitudinal relative movement by the engagement of co-operating formations 17, 18. The combination provides particularly flexible mattress arrangement which also avoids the problem of the leg section of the mattress kicking upwardly when a profiling bed is articulated.
