A mattress structure (30) having a plurality of side-by-side lower support elements (50), a layer of material (54) underlying the lower support elements (50), and a plurality of side-by-side upper support elements (52) overlying and being supported by lower support elements (50) is described. The upper support elements (52) are connected by a plurality of tethers (128) to the layer of material (54), with the tethers (128) extending between adjacent lower support elements (50). Each of one of the upper support elements (52) and lower support elements (50) is an inflatable air bladder with specified sets of air bladders defining tube set zones (142, 144, 146). The pressure of the zones (142, 144, 146) is controlled by an air pressure system (170).

Les éléments (52) de support supérieurs sont reliés à la couche de matériau (54) par une pluralité d'attaches (128), lesdites attaches (128) s'étendant adjacentes aux éléments (50) de support inférieurs. Chacun des éléments (52) de support supérieurs et des éléments (50) de support inférieurs est une poche gonflable, des ensembles déterminés de poches à air définissant des zones (142, 144, 146) d'ensembles de tubes.
