Armless office chairs lessen the likelihood of running into and damaging tables made of soft materials, such as the edge of an office desk made from wood. Since these chairs do not have armrests, they take up minimal space and are suited for small workstations and cubicles.

Adjustable-arm office chairs have movable arms that raise, lower, flip up, or slide to one side to accommodate individual seating preferences. The armrests reduce the load on shoulders, neck, wrists, and arms and aid with getting in and out of a seated position.

Fixed-arm office chairs have supports that reduce the load on shoulders, neck, wrists, and arms and aid with getting in and out of a seated position.
