Seat Height:

A good ergonomic chair is highly adjustable to meet the requirements and dimensions of its user. Everyone’s height is different; therefore it is crucial to get a chair with adjustable height. As per guidelines, your feet should lie flat on the floor. For most people, a seat height of average 16 to 21 feet is generally suitable.

Seat Depth and Width:

A good ergonomic chair allows its user to sit without any pressure to the back of his knees and provides support through the backrest, buttocks, & thighs. It leaves around 2 to 4 inches between the seat edge and back of your knees. The average seat depth is around 17 to 20 inches.

The forward and backward tilt can be altered. The prolonged sitting with pressure on your knees can affect your blood circulation and cause deep venous thrombosis conditions.

Seat Tilt:

When a person sits for a long time, a condition called anterior pelvic tilt arises. It is due to pressure on the pelvis. And to correct the positioning of the pelvis, an ergonomic chair provides support to keep the pelvis in a normal position.

Lumbar Support:

The lumbar refers to your lower back. This feature should essentially be present in your ergonomic chair. Since prolonged sitting can cause back pain, it is important to have this feature on your ergonomic chair.

An ergonomic chair provides lumbar support by supporting the natural S shape of the spine without restricting the movement. It prevents slouching and stress given to the spine due to long sitting times. It is recommended to change the back setting two to three times a day to avoid giving pressure to your back at one point.

There are three types of lumbar support provided by ergonomic chair:

  • Fixed lumbar support
  • Adjustable lumbar support
  • Dynamic lumbar support

Neck Support/ Head Rest:

A headrest or neck support aid in supporting the back of the head or upper neck. It is not a default feature. But if you suffer from neck pain or stiffness, then you should go for this feature. By supporting your head, it reduces the stress in your upper torso.


An ergonomic chair supports the natural curve of your spine taking some pressure off from your disc and back. This feature adjustment comes with both vertically and forward & backward positions.

Furthermore, the height and width of the backrest should be appropriate to support your back so that it doesn’t restrict your movement. It is usually around 12 to 19 inches wide.

Quality castors

An ergonomic chair has one or two castors to supports your whole body weight when entering or exiting your chair. Cheap quality castors break down easily making your chair useless. Therefore, when you buy an ergonomic chair, it is important to look for the quality of castors.

Seat material

The seat material of a good ergonomic chair is always good. It is always comfortable and well padded. The fabric used should not only be sweatproof but also enough breathable to not cause sweat. The most preferred material used is Mesh. It is breathable and easy to clean. The other material used is Leather which is also easy to maintain and has high durability but it is expensive.

In terms of shape, a waterfall edge seat helps relieve pressure on the back of the thighs and regulates the blood circulation to your legs.


The armrest of your ergonomic chair provides support to your upper body by taking the weight off your shoulders and thus reducing the tension to your upper body.  The armrest is adjustable for both height and width in a good ergonomic chair and can be pivoted inwards and outwards.

That being said, you should not use an armrest while typing or only support your elbows as this increases the tension in your wrists and can cause strain.


Whether it’s a conventional chair or ergonomic chair, a swivel helps in rotating the chair in all directions to reach every area of the desk without straining yourself.


Often overlooked, wheels are an important part of an ergonomic chair. if you use the chair on a hard surface, get the chair with rubber wheels. But if you want to use the chair on the carpet, consider getting the one with hard wheels.
