ABSTRACT:
A device is disclosed for facilitating rotation of a mattress in a horizontal plane carried by a box spring or a platform. In order to facilitate rotation, slick surfaces between the mattress and the box spring or platform are selectively placed in contact in order to reduce the normal friction therebetween. The slick surfaces may be provided by two (2) separate covers; one cover for the mattress and one cover for the box spring or platform. A first cover is provided with a slick and non-slick surface. In order to further facilitate rotation, a second cover includes a slick surface on one side and forms part of a levitation device. The other side of the second cover may be formed with a slick or a non-slick surface. A levitation device creates an air cushion between the mattress and the box spring under the influence of an air supply which lifts the mattress and allows the mattress to be rotated in a horizontal plane virtually effortlessly.
