Office Chairs

Look for adjustable seat height, adjustable armrests, lumbar support, a tilt control and a wheeled base. Seat depth should support your thighs without pressing the back of the knees; a breathable back helps over long sessions.

Mesh is breathable and stays cool — good for warm rooms or long sessions. Leather or faux-leather is more cushioned and formal but warmer against bare skin. Both can offer solid lumbar support; it's mostly climate and look.

Set seat height so feet are flat and thighs level; adjust the lumbar to your lower-back curve; set armrests for 90-degree elbows when typing. Take a short break every 30-60 minutes regardless of chair quality.

Standard hard casters can mark hardwood. Use a floor mat, or swap to soft polyurethane casters made for hard floors. For a stationary base, felt pads under the feet also protect the surface.

Most take about 15-30 minutes — fitting casters and the gas lift to the base, the seat to the lift, then the back. The hardware needed typically ships with the piece; some steps are easier with the chair upside down.

With daily use, a quality chair often lasts 5-10 years. Wear shows first in cushion compression, armrests and the gas lift. Cleaning the fabric and lubricating moving parts yearly extends life; replace if the lift sinks or upholstery tears.
