How to Choose the Right Office Chair for Your Height and Body Type

The right office chair can be the difference between pain and no pain during long hours of desk work. Since the human body wasn't built to hold one position for hours at a time, an ergonomic chair helps reduce strain on the back and supports better posture.

Price and quality

Top-tier chairs, which can cost more than $2,000, offer extensive adjustability and long warranties, but they're aimed at people who spend many hours a day in their seat. Budget models around $200 tend to suit only average-sized bodies, while chairs starting around $500 typically include adjustable lumbar support and seat depth, making them suitable for most people.

Posture and lumbar support

The ergonomic goal is to keep the back straight and fully supported, thighs parallel to the floor, and feet flat on the ground. Because the spine has a natural S-shaped curve, lumbar support helps prevent the discomfort caused by sitting in a hunched position. Chairs with lumbar support that adjusts both vertically and horizontally are recommended for a better fit to the back's curve.

Armrests matter less than expected

Ergonomics experts note that arms can hang naturally at the sides of the body, so armrests aren't strictly necessary — they're mainly useful when leaning back. On cheaper chairs, armrests are often bulky and can get in the way of good posture.

Seat height and depth

Ideal seat height depends on height: 14 to 16 inches for people 5'2" and under, 16 to 19 inches for average heights, and 18 to 22 inches or more for people over 6 feet tall. Seat depth should be chosen similarly, leaving two to three fingers of space between the knee and the edge of the seat. Desk height matters too — a standard 29-inch desk is too tall for many women and a fair number of men.

Considerations for larger-bodied people

People with larger builds are advised to avoid cheaper mesh chairs, which can restrict circulation, and to pay attention to a chair's weight rating and seat width. Finally, experts recommend trying a chair in person before buying to confirm it's the right fit.
