Abstract

At least a pair of separate cushioning members are interconnected by an overlying face of a cover and disposed side by side at the side regions, border strips are secured each along one of their edges to a corresponding inner skin overlying one main face of a cushioning member, at the opposite main faces corresponding cover sheets are secured at the other edges of the border strips; the interconnecting cover overlies the inner skins and is secured along its periphery to them and to the first-mentioned edges of the border strips. The method includes joining two border strips each to one edge of an inner skin, drawing them round a cushioning member and securing a cover sheet to each, over laying an additional cover sheet over both skins and securing it peripherally to them and the adjacent edges of the border strips forming two pouches one to both sides of a hingeable fold zone of the overlying cover sheet. A matress is provided, foldable for transport on stairways and access to a support with a corresponding hingeable base board.

Foldable cushioning comprising:

a pair of separate cushioning members, each cushioning member having opposed faces and peripheral side regions extending between said opposed faces, said cushioning members being disposed side by side with respective portions of said side regions being disposed adjacent to and extending substantially parallel to each other;
a pair of border strips, each border strip extending around and over a respective cushioning member side region and having first and second edges;
a pair of inner skins, each inner skin overlying one face of a respective cushioning member and being secured to the second edge of a respective border strip;
a pair of cover sheets, each cover sheet overlying the other face of a respective cushioning member and being secured to the first edge of a respective border strip;
and
a further largest cover sheet overlying both of said inner skins, said further cover sheet having a peripheral edge which is secured to at least a portion of the second edges of the respective border strips in a manner such that a pouch is defined between said further cover sheet and each of said inner skins and such that the portion of said further cover sheet extending between the adjacent portions of the side regions of said cushioning members comprises a band-like portion constituting a hinge-like fold zone.
