1. A bed comprising:
- means for defining an upwardly facing support surface;
a mattress supported on said support surface and having first and second inflatable cells, said first inflatable cell having a wall defining an inlet for receiving a pressurized fluid, the second inflatable cell having an inlet for receiving fluid for inflating said second cell;
an outlet coupling member spaced from said first cell inlet for transmitting fluid input through said first cell inlet; and
means selectively connectable to said outlet coupling member for joining said second cell inlet to said outlet coupling member, whereby fluid received in said first cell inlet is also received in said second cell.

6. A bed comprising:
-
means for defining an upwardly facing support surface;
a mattress supported on said support surface and having first and second inflatable cells;
a housing for defining a first fluid-flow path, said housing including a first fluid-flow port in communication with said first fluid-flow path, and an upper wall adjacent to said inflatable cells, said first fluid flow path being adjacent to said upper wall, said housing further defining a second fluid-flow path and having an intermediate wall positioned between said first and second fluid-flow paths, a second fluid-flow port in communication with said second fluid-flow path; and
means for coupling selectively said first and second fluid-flow paths to a cell. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)
