A cushioning layer for lowering the unit area pressure between a supporting surface and an irregularly shaped body and comprising a flexible base layer (10); and a plurality of resilient, shaped protrusions (11), each protrusion upstanding from said base layer and arranged to contact a surface of said body; wherein said cushioning layer is capable of resilient compression by way of deflection of said protrusions (11) thereby to reduce the unit area pressure between the supporting surface and the body, and to permit air to circulate between the protrusions (11) and to contact the body surface. |
