A height-adjustable armrest for a chair, in particular an office chair, has an arm support, which is retained by an armrest holder. The armrest holder is pivotable and a pivoting causes the armrest to be adjusted in height. An arresting device fixes the armrest holder in a height position. The arresting device is arranged at the upper, alterable-height end of the armrest holder and has a linearly movable latching element. The latching element is connected via a guide element to the armrest holder such that each pivoting movement of the armrest holder induces a linear movement of the latching element.

A lift chair includes a lift mechanism that maintains a continuous seating position during forward and elevated movement by supporting the occupant's seat, arms and back. The mobile section of the chair will also lower the occupant to the normal seating height. The gel cushion seating surface is attached at least to the moveable section of the lift chair. The gel cushion seating surface of the chair has a plurality of gel cushion cylinders arranged in a grid that provide a rhythmically changing support area at multiple points on the occupant's buttocks and thighs. This provides a comforting massage which reduces stress on the body associated with prolonged seating.
