The above object of the present invention can be achieved by a chair having the following structure. That is, the gist of the invention is that between the leg portions that are erected at a certain interval, a reversible seat portion that has a double structure of a backrest and upper seat portion and a lower seat portion whose base ends are connected and supported is , The base portion front side of the backrest and the upper seat portion and the leg portion are connected and pivoted together, and the middle portion of the lower seat portion and the leg portion below the lower seat portion are connected and pivoted together by a connecting rod, A reclining chair with a variable seat height, characterized in that a backrest is attached to the rear of the leg. Further, the auxiliary leg portion is extended to the tip of the lower seat portion, or the leg portion is provided with a stopper portion for locking the lower seat portion after the reclining conversion.

[0005]

The function of the reclining chair of the present invention is shown in FIGS.
As shown in FIG. 3, by inverting the backrest / upper seat 4 in the direction of the arrow A in the figure, the seat height, the seat angle, and the inclination angle of the backrest / upper seat 4 are moved while the lower seat 5 moves forward. It can change at the same time and reclining conversion. The lower seat portion 5 is fixed in place by the stopper portion 10.
