Abstract
A chair has a backrest assembly, a foot tube assembly, and an armrest assembly. The armrest assembly comprises an armrest slidably connected with an armrest base. The armrest base is operatively connected to an upper portion of the foot tube assembly. A back end of the armrest is operatively hingedly connected to the backrest assembly. An elastic member is operatively connected to the armrest and the armrest base. The elastic member extends in a direction of sliding of the armrest relative to the armrest base. A lock is moveable between an engagement position wherein the armrest is fixed to the armrest base and a disengagement position wherein the armrest is slidable relative to the armrest base under bias from the elastic member. The chair may be foldable.
