A watermattress (11) comprising a bladder (17) formed of water impervious sheet material and having a major top panel (21), a major bottom panel (23), and a side panel (25). The bladder (17) can be filled with water. The side panel (25) has an initial shape when the bladder (17) has no water within it and a first particular shape when the bladder (17) is filled with water. A sidewall (27) extends laterally of the bladder (17) for supporting the bladder (17). The sidewall (27) has a top surface (29), a bottom surface (31), and a side surface (35) facing the side panel (25) of the bladder (17). The side surface (35) of the sidewall (27) has a second particular shape when the sidewall (27) is in a generally uncompressed state. The first particular shape is generally complementary to the second particular shape. A mattress cover surrounds the bladder (17) and the sidewall (27).
