<p>A mattress system is disclosed which permits the, or each, user to select readily the mattress firmness either for a single bed, or independently for each half of a bed to be used by two people. Regardless of the firmness chosen, the overall thickness is maintained constant. The mattress (11) comprises a plurality of foam mattress elements (12-16, 22-26), of different firmnesses, together with a substantially rigid core (17, 27) element; alteration of the sequence in the set changes the firmness. A two person mattress includes two sets of mattress elements. Additionally, a torso board can be included to provide a localized firmer surface. The system also provides an essentially smooth transition between two sets when used, for example, in a double bed.</p> |
