By changing the engagement position of the rod, the easy chair can be used as a seat, and the inclination angle of the seat part of the seat can also be adjusted. Reference numeral 4 denotes a vertically elongated U-shaped rear leg lever that intersects with the front leg lever so as to be openable and closable. are bent 6 outward, respectively, and the bent portions are engaged with the locking holes 3. Support rods 7 are formed in an inverted U shape and are installed on the upper surfaces of both sides near the bottom of the front leg lever, and support the upper end of the rear leg lever when folded. Connecting rods 8 are installed on both sides of the lower end of the rising section, and connecting rods 9 are installed on both sides of the upper ends of the rear leg rods, a seat cloth 10 is stretched between the connecting rods, and an inverted U is installed on the upper end of the rising section. backrest frame 1
1 is pivotally extended with a pivot 12 to form the main body of the chair, which includes a backrest part 13, a seat part 14, and a footrest part 15.
A series of mats 15' are attached to the main body of the chair.
