摘要：
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).
