Abstract

The utility model discloses a folding bed. A liner layer is arranged on the bed surface of the folding bed; and the liner layer comprises an outer sleeve and a foaming filler arranged in the outer sleeve and composed of foaming tubes. The foaming tubes are made of a porous elastic material containing an ingredient which is similar to sponge, and differences of the material from that sponge are as follows: the foaming tubes are directly formed to be tubular during the production process; and therefore, each foaming tube is provided with a hollow tube cavity along the own axis direction. Because the foaming tubes are provided with the hollow tube cavities, before compression, the liner layer filled with the sponge is lighter than the liner layer filled with the foaming tubes in weight, wherein the thickness of the sponge is same with that of the foaming tubes; and after the compression, the tube cavities of the foaming tubes can not occupy space, and the liner layer filled with sponge is smaller than the liner layer filled with the foaming tubes in volume, wherein the thickness of the sponge is same with that of the foaming tubes. Therefore, by using the foaming filter taking the foaming tubes as main bodies, the purposes of reducing the weight of the folding bed and reducing the volume of the liner layer after being compressed can be realized on the premise of ensuring the thickness of the liner layer.
