An alternating pad consisting of transverse inflatable cells ( 1 and 2 ) alternately inflated and deflated. An internal cell ( 5 ) is provided at the outermost edges of each transverse cell ( 1,2 ). The internal cell ( 5 ) is constantly inflated at a higher pressure than the traverse cells ( 1, 2 ). The internal cell ( 5 ) is at a lower height than the cells ( 1,2 ) and preferably of a chamfered shape to provide optimum pressure relief across the whole surface of the pad. The internal cell ( 5 ) provides stable patient exit, entry or transfer from a bed or seat.
