Abstract
A chair is provided with adjustable armrests. The chair has two vertical guiding bars, each of which extends down from a lateral side of a back thereof, and each of which has engaging trenches spaced along it. Each armrest has a connecting space extending vertically through a rear end thereof, and is up and down movably connected to a corresponding guiding bar at the connecting space thereof. A lever is pivoted to a bottom of the rear end of each armrest. Each lever has an engaging projection, which can be fitted into one of the engaging trenches of corresponding guiding bar to make the armrest unmovable by means of pivoting the lever to the locking position. When the levers are in the unlocking position, the armrests can be adjusted in height.
