<p>A cot (1) having side (4,5) and end rails (6,7) is provided in which the end rails (6,7) are mounted to at least one side rail (4,5) in a manner enabling the end rail (6,7) to move between a first position generally parallel to the side rail (4,5) to a position generally perpendicular to the side rail (4,5). Pairs of opposed side rails (4,5) and end rails (6,7) are constructed and arranged to form a frame (100). A bed sheet (10) is supported on the frame (100). The bed sheet (10) has a tension device (80,81) associated with it permitting a user to vary the tension of the bed sheet (10) with respect to the frame (100).</p> |
