How to adjust an ergonomic chair?
As mentioned above, an ergonomic chair features many different adjustments so that it can fit your sitting posture. Learn how to adjust an ergonomic chair right below.
How to adjust chair height?
The first step to getting your ergonomic chair adjusted to your body is getting the seat height correct. Adjust the height of the seat pan to just below your knee caps.
Sit in your chair with your back firmly against the chair back and adjust the seat cylinder to the proper height.
Adjust the height of the chair so your feet are flat on the ground and your legs form a 90-degree angle. Your knees should align with or rest slightly lower than your hips.
Over time, if you feel pressure near your butt, raise the chair a little. If you feel pressure at the front of your leg, lower the chair.
Adjust seat depth
This feature allows you to lengthen or shorten the chair seat pan. The depth of your seat can make all the difference in comfort.
A shorter person will want the seat closer to the chair back and a taller person will want it a little further away.
You should have at least a two finger width gap behind your knees and the front edge of the seat when sitting.
To change the length of the seat pan, you will need to hold the lever/bar and slide the seat forward or back on the base.
Sit on the chair and keep your feet flat on the floor, then check that the clearance between the seat and your calves.
If the front of the seat is digging into the back of your knees, slide the seat back a little. If you have too much room and your knees are sticking out, slide the seat forward.
Adjust lumbar support
Adjustable lumbar support is a feature most people seek out when looking for an ergonomic chair.
The lumbar support should fit right in the natural curve of your spine, typically at the small of your back directly above your belt line.
Some chairs have built-in lumbar, while others allow you to adjust it.
Depending on the type of chair, the lumbar support may be adjusted by raising or lowering a lumbar bolster, or sometimes the entire chair back moves up and down on a ratchet mechanism or post.
Place the lumbar portion of the chair so that it is comfortable for you and fills the hollow in the small of your lower back.
Your arms should rest comfortably at your side to relieve strain and pressure from your upper back and shoulders.
Armrests are usually height adjustable, but many ergonomic chairs include armrests that are depth adjustable and have the ability to pivot both in towards your body and away as well.
Your armrests should always be at the same height. They should sit at about elbow height when your arms are vertically against your sides.
If your armrests have width or can pivot, move these until they fit you comfortably.
There is typically a button on the side or bottom of the armrest that allows you to move it up or down.
There may also be a knob or latch on the underside of the armrest where it meets the chair base that allows you to move the armrest in or out.
If your ergonomic chair has a headrest, make sure it’s properly adjusted as well.
Adjust the headrest to the base of the back of your head. Your head should not feel like it’s being pushed forward or downward.
There are many types of headrests. Some features a height adjustable headrest.
The feature set which causes the most confusion is the chair rock and tilt mechanisms. People often pull the tilt lever on their chair once, experience the fright of nearly being ejected out of their seat or falling back suddenly, then never touch that lever again.
Chair tilt rock/lock: When locked, this lever prevents the chair from rocking back.
When unlocked, the chair is able to rock back and forth like a rocking chair.
The adjustment is typically found on the right side of the seat pan, and may be a lever you pull up or push down, or could be a knob you pull out or push in.
Seat tilt: Seat tilt works in conjunction with the chair rock feature above.
The seat tilt lever/knob is typically located closest to the front edge of the seat and allows the seat pan to tip forward when unlocked and with the chair in rock mode.
On many chairs, to lock or unlock the seat tilt, you must first unlock the tilt rock and physically rock back in the chair.
In this rearward leaning position, unlock the seat pan tilt by adjusting the knob or lever.
To lock the seat tilt back into a flat position, rock back in your chair again and move the seat pan knob back to its starting position.
Tilt tension: This knob controls the amount of resistance required to move the chair when in the rock mode.
The tension knob is typically located under the seat pan, or on the right side of the chair.

Ergonomic chairs are an excellent choice. However, keep in mind that simply owning one is not enough to preserve your back.
Once you have determined the optimal height of your desk, you will need to select appropriate seating. You need to adjust it to your individual proportions.
Adjust the height of your chair
Sit as close to your desk as you comfortably can. With your upper arms parallel to your spine, place your hands on the surface of your desk.

Adjust your backrest
With your body situated against your backrest, form a fist and place it between the back of your calf and the front of your chair.
If you do not have enough space for your fist, your chair is too deep and the backrest needs to be adjusted forwarded.
You can use a cushion or a rolled up towel to achieve low back support in case the back of your chair cannot be adjusted.
Place objects within arm’s reach
Keeping the items you use most frequently within arm’s reach help you reduce your need to stretch and consequently reduce your risk of straining a ligament.
This prevents the need to break your current position and helps you maintain correct posture for longer periods of time throughout the day.
Practice correct sitting posture
Preserving the health of your spine also requires active muscle use in order to maintain correct posture.
To minimize the amount of stress placed on your back, you should sit as close as possible to your desk with your head upright, your upper arms parallel to your spine, and your hands rested at a 90-degree angle on your work surface.
Your legs should also be positioned at 90 degrees, directly above your ankles.
Last but not least, don’t forget to stand up and walking around after a long sitting time.
Stretching will help relieve your body of the aches and pains that develop from being stationary, work-related back pain can also be the result of stress.
