This Mainstays high-back office chair is a practical seat for indoor desk work, study, and everyday workspace tasks. It pairs a fabric seat with a mesh back and sits on a black nylon base, giving it a clean, simple look that settles easily into home offices, studios, and shared work areas. The flip-up arms are the standout detail: they lift up when you want added support and move out of the way when you need more room at your desk. Pneumatic seat-height adjustment lets you raise or lower the chair to match your setup, with an overall assembled height that ranges from 37.5 to 42.25 in. A pronounced lower lumbar support panel follows the shape of your lower back, while a padded foam seat and five dual caster wheels round out the seating and mobility hardware. It is designed for indoor use and wipes clean with a damp cloth. Minimal assembly required. Model: MS53100081252BK.
