Chair

A chair, comprising:

• a seat;
• a supporting leg set capable of being supported on a supporting surface, the supporting leg set comprising a first supporting leg set, the first supporting leg set being pivotally connected to the seat and being capable of switching between a leg unfolded position and a leg folded position relative to the seat;
• a first driving member movably disposed on the seat, connected to the first supporting leg set and extending along a first direction, the first direction being parallel to the supporting surface, wherein pivoting of the first supporting leg set relative to the seat drives the first driving member to slide relative to the seat;
• and
• a locking mechanism slidably disposed at a bottom of the seat along a second direction and located outside the first driving member in the second direction, the second direction being parallel to the supporting surface and different from the first direction, wherein sliding of the locking mechanism relative to the seat locks or unlocks sliding of the first driving member relative to the seat.

• and
• a folding mechanism, the folding mechanism comprising:
• a first driving member connected to the first supporting leg set and extending along a first direction, wherein pivoting of the first supporting leg set relative to the seat drives the first driving member to slide relative to the seat;
• and
• a guiding member movably disposed on the seat and linked with the first driving member for guiding the first driving member to slide relative to the seat, thereby guiding the first supporting leg set to fold or unfold relative to the seat.
