<p>The method is using a foldable bed bottom (10) on a bed structure. The bed bottom (10) has a head portion (12) rotatably attached to a back portion (14) that is rotatably attached to a sit portion (16), that in turn, is rotatably attached to a thigh portion (18). The thigh portion (18) is rotatably attached to a first leg portion (20) and a second leg portion (22) so that the first leg portion (20) is separate from the second leg portion (22). The bed bottom (10) may be placed on a bed structure and easily removed therefrom by simply lifting the bed bottom (10) therefrom. The bed bottom (10) may then be folded into a compact size and then be expanded again before being placed on a second bed structure.</p> |
