A foldable, inexpensive, easily assembled recreation chair-pad combination can be folded into a compact manually carried luggage piece. Basically, an exterior, double folded cover is separately formed into three closed compartments and a cover extension. Each compartment is formed and separately secured by the three doubled cloth hinges, which are secured by securing means such as multiple grommets disposed and secured along the three hinge lines. A foam pad two inches thick by about 15×15 inch square is disposed and secured in one first end compartment. Similarly, a ¼inch thick plywood backing sheet, and a 2 inch thick foam pad of equal area to the above are disposed in the two adjacent compartments. Velcro matching fastener strips are adaptively sized, placed and secured on the opposed sides of the cover, positioned to cohere to each other on folding the chair-pad into a multiple folded piece of luggage, folded at the three hinge lines. The chair-pad can be arranged and positioned into an A-frame structure in which the two plywood panels are structurally erected in two adjacent compartments directly facing each other, and a soft foam seat compartment rests on a canvas extension compartment. The body pressure of a human sitting on a soft foam seat anchors the A-frame chair pad in position. The chair-pad can also be folded out into a flat pad.
