A mattress or mattress topper

A mattress comprising a core layer 110, a quilt layer 122A, and an upholstery layer 120 between them comprising a moisture transport layer 124A and a moisture holding layer 124B where the holding layer has a greater water absorbency by weight than the transport layer and the transport layer is formed of a pleated non-woven web of fibres. Also claimed is a mattress topper without the core layer. Preferably the fibres of the holding layer are smaller and less densely packed than the fibres of the transport layer. Preferably the fibres of the non-woven web in the transport layer are in an anisotropic arrangement. In use the transport layer draws sweat away by capillary action and it is absorbed by the holding layer- it can then evaporate away when the mattress is not in use.
