In a method for preparing a mattress for storage or transport, a mattress is used in which an elastically deformable cushion structure and a support apparatus, adjustable by electric motor and having a dimensionally stable base body, are accommodated in a casing. The support apparatus has at least two support parts that are pivotable relative to one another. The mattress is introduced into an essentially gas-tight wrapping, and the wrapping is sealed essentially gas-tight, and a negative pressure is generated in the wrapping to achieve vacuum-induced compression of the cushion element of the mattress. In the compressed state of the cushion element or during the compression of the cushion structure, the support parts are folded together, and the casing is sealed essentially gas-tight so that the mattress in the compressed and folded-up state forms a compact storage and transport unit.

A pressure sore prevention mattress is provided alternating pressure points on the body of an occupant that is easily transformable between two stable configurations. The four-layer mattress construction has a top foam pad, a webbing layer, a dynamic layer of deformable panels trapezoid-shaped four-bar mechanisms that deform to produce an undulating pattern of peaks, and a base. Panel geometry can determine peak height. The mattress has a spatially hollow geometry that allows natural air convection through the breathable top foam pad to enable drying of moisture as well as the use of forced air convective drying or cooling. The mattress can be transformed from one configuration to the other while the occupant is on the mattress.
