Abstract
A support surface assembly comprises a support surface and a multi-zone chamber comprising two or more inflatable bladders forming the support surface. In an example, first and second bladders of the multi-zone chamber are arranged in a head to toe configuration and are substantially free to move with respect to one another. In another example, a flexible joint is included between first and second bladders, the flexible joint including one or more releasable fasteners. In another example, a fluid communication conduit between first and second bladders couples the first and second bladders in a series fluid communication. In another example, the bladders form an array of bladders arranged in series from a head to a foot of the support surface, wherein each of the bladders has substantially the same dimensions.
