Ergonomic mesh office chair with lumbar support and headrest

What a good chair does

A chair has one job: hold you in a neutral posture for hours without you noticing it. That means a seat height you can set so your feet are flat, a backrest that supports the curve of your lower back, and armrests that let your shoulders relax. Everything else is comfort, not health.

Features worth paying for

Adjustable lumbar support (height and depth), seat depth adjustment so two or three fingers fit between the seat edge and the back of your knee, armrests that move up and down, and a tilt that locks. A breathable mesh back helps in warm rooms. Headrests only matter if you recline a lot.

Size, weight and warranty

Chair sizes vary more than people expect. Check the seat height range against your own desk height, and the weight rating against your weight. ANSI/BIFMA X5.1 testing is based on a 275 lb user; if you are heavier, choose a chair rated for you. Read the warranty for the gas cylinder and mechanism separately.

What should I look for in an office chair for back pain?

Lumbar support that adjusts in height and depth, seat depth with two or three fingers of clearance behind the knee, armrests that move and a tilt that locks at a slight recline of 100 to 110 degrees. Check the seat height range against your desk and the weight rating against your weight.

FAQ

Is a $150 chair good enough?

Often yes, if it has adjustable height, a real lumbar support and a return window. Our under-$200 guides list the ones that hold up.

Mesh or foam?

Mesh stays cooler and keeps its shape; foam feels softer at first. For long days most people do better with mesh or a hybrid.

Why does my back still hurt in a good chair?

Usually the chair is set wrong or the desk and screen are off. Run the Ergonomics Self-Check.
