Then what makes a chair ergonomic?

Seat height

What makes a chair ergonomic is its seat height adjustment.

Everyone is different, so it is important that the seat height can be altered. The optimal seat height should allow you to place your feet flat on the floor.

A seat height that ranges from 16 to 21 inches off the floor should work for most people.

Seat width and depth

Proper seat depth should leave between 2 and 4 inches between the edge of the seat and the back of your knees.

If the seat is too far forward, it may put undue pressure at the back of the knees.

Seat tilt

What makes a chair ergonomic is also the seat tilt.

Good ergonomic chairs allow the seat to tilt for correct positioning of the pelvis. Anterior pelvic tilt is a posture problem that affects almost everyone who sits a lot.

So it’s important to keep the pelvis in a neutral position when sitting, with 80-degree angles at the hips, knees and ankles.

Backrest lumbar support

The support given to your lower back is an essential feature of an ergonomic chair. This is what makes a chair ergonomic.

An adjustable backrest allows users to align the curve in the chair with the curve in their spine.

Ergonomic chairs support the natural S shape of the spine, which prevents slumping and reduces stress on the spine and the pelvis.

Backrest recline

An adjustable backrest is what makes a chair ergonomic. It allows people to move the backrest to more specifically support their natural spine position.

A good ergonomic chair is made out of comfortable materials. The material should not cause the user’s back to sweat.
