Thereafter, the fixing member 124 is coupled to the knee plate 160 via the rotating shaft 161, and the knee plate 160 is detachably coupled to the supporting rod 122 or the connecting rod 230 by the fixing member 124, and the knee plate 160 is freely rotatable about the rotating shaft 161.

[0081] In other embodiments, an angle adjustment device may be disposed between the knee plate 160 and the fixing member 124. The knot device is used to adjust the angle of the knee plate 160 to the horizontal plane. Since the force that the knee plate 160 is subjected to will generally be less than the force that the seat plate 110 is subjected to, the angle adjustment device may preferably consider a frictional setting scheme.

In the present embodiment, as shown in FIG. 8, the table top 210 is further provided with a stopper 211 for preventing the object from slipping off, and the stopper 2 11 is detachably disposed on the table top 210. In this embodiment, the stopper 211 is provided on the table top 210 near the chair 100.
