Cushion structure

Abstract

A cushion structure is provided. At least one roller unit is provided on the bottom of a sliding cushion. Corresponding to each of the at least one roller unit is a guiding rail positioned on the top end of a base so as to allow each of the roller unit to move within the guiding rail, respectively. A combining portion is positioned on two sides of the sliding cushion, respectively; each combining portion is screwed on the two sides of bottom of the sliding cushion, respectively. The inner side of each of the combining portion is provided with a guiding trail for containing each of the protrusion so as to allow each of the sliding cushion to move back and forth. Therefore, the present invention has the advantages of energy saving, easy to use, easy to carry, space saving, easy to assemble, low manufacturing cost, and good stability. The present invention is also suitable to use for any age group.
