Abstract
A chair includes a chair base, a seat mounted on top of the chair base, a backrest pivotally attached to a rear of the seat, and a chassis mounted below the seat. When the backrest is tilted rearward, the seat moves forward and urges a movable member of the chassis to shift. The chassis further has a positioning mechanism with at least one positioning plate for retaining the backrest in a desired inclination angle. The positioning plate carries a rear end of the seat upward when the backrest is tilted rearward, thereby further improving the sitting stability.
