PROBLEM TO BE SOLVED: To keep a comfortable posture by forming each middle part of two bar shape frames to be projected upward by means of bending in a folding bed where a seat back part and a foot rest part are pivotally supported at the both end parts of a seat part in a front and rear direction, which is constituted by means of suspending sheet bodies over a part between a pair of left and right bar shape frames, to be freely rocking possible. SOLUTION: The horizontally arranged seat part 10 for supporting a part between the buttock part and the thigh part of a user is formed to be a frame structure where the two seat part frames 11 consisting of pipe materials are arranged in parallel in left and right. The respective seat part frames 11 are formed to be a shape where a center part is projectingly bent upward and outward. The backrest part 20 is pivotally supported in one end of the seat part 10 and the foot rest part 30 is in the other end so as to be freely rocking possible and also leg bodies 40 and 40 are disposed at both the ends of the seat part 10. Then three synthetic resin belt bodies 60 are stretched over the whole length of the folding bed 1 and also the sheet bodies 12, 22 and 32 are suspended over the seat part 10, the backrest part 20 and the foot rest part 30 to respectively cover the belt bodies 60 so that the user can sit on it.
