Adjusting an Office Chairs
Choosing the Correct Chair

To avoid back pain and problems, you should sit on a properly adjusted office chair when working at a desk height for computer work or studying.

People who sit for long periods of time on unfitted ergonomic office chair commonly develop seriously overstretched ligaments in their spines, as well as disc problems.


Method 1- Adjusting An Office Chair

workstation is the right height

Make sure your workstation is the right height.

Ideally, your workstation should be able to be adjusted in height, but few do.

In the event that your workstation cannot be adjusted, you will have to adjust the height of your chair.

Make sure that the highest point of your workstation is just below your kneecap if your workstation can be adjusted.

When you sit with your hands resting on the desk top, adjust your office chair height so that your elbows form a 90-degree angle.

Workstation angle affects elbow angle

Workstation angle affects elbow angle.

You should sit as close to your desk as you feel comfortable in office with your upper arms parallel to your spine.

You should rest your hands on the surface of your workstation or your computer keyboard, depending on how often you will use them.

It is ideal for them to be 90 degrees apart. Under the seat of your chair, feel for the height control as close as possible to your workstation. On most computers, it is located on the left side.

If your hands are higher than your elbows, the seat is too low. Once your body is raised off the seat, press the lever. The seat will rise as a result.

Lift the lever and let go when it is at the desired height. Once you’ve reached the desired height, keep seated and release the lever.

Your feet should be level with your seat

Your feet should be level with your seat.

Sitting position in an office chair with your feet flat on the ground, slide your fingers between your thigh and the edge of the chair.

You should have a space about the size of your fist (about 5 cm or 2 inches) if your calf is touching the edge of the chair.

The height of your office chairs and workstation will need to be raised if you are very tall and there is more than a finger’s width between them.

To attain a 90-degree angle at your knees, raise your feet flat if you have difficulty sliding your fingers under your thigh. By using an adjustable footrest, you can create a higher surface for your feet flat.

calf and the front of your office

Distance between your calf and the front of your office chair should be measured.

Try to pass your fist between your office chairs and your calf. Your calf should be separated from the edge of the chair by a fist-sized space (about 5 cm or 2 inches). The adjust seat depth of the chair is determined by this measurement.

You’ll need to bring the backrest forward if it’s tight and difficult to fit your fist in the space. In most ergonomic office chairs, you can do this by turning a lever on the right side of the seat.

Use a low back or lumbar support if the chair’s depth can’t be adjusted. You can adjust the back backward if there is too much space between your calves and the edge of the chair.

A lever will usually be located on the right side of the seat below the seat. In order to avoid slumping or slouching at work, the depth of your office chairs must be correct. A good lower back support will minimize the strain on your back and help you avoid low back injuries

Adjust the height of the backrest.

Adjust the height of the backrest. 

With your feet down and your calves a fist’s distance from the chair’s edge, move the backrest up or down to fit your back properly.

It will provide the best back support this way. Over the lower back’s lumbar support, you should feel firm support.

A knob should be located on the back of the chair that allows the backrest to be adjusted.

The backrest is easier to raise while standing than to lower while sitting, so start by raising it all the way. 

Once you are seated, adjust the backrest of the chair so that it fits in the small of your back. You may not be able to adjust the backrest height on all chairs

front edge of the seat curves towards the floor

Adjust the angle of the backrest to fit your back

Sitting in your preferred good posture should be supported by a backrest at a comfortable angle. You shouldn’t have to lean back to feel it, nor should you have to lean forward further than you usually do.

The back of the chair will have a knob that locks the backrest angle in place.

Lean forwards and backwards while watching your monitor while unlocking the backrest angle. After you have reached the right angle, lock the backrest in place. It is possible to adjust the angle of the backrest on some chairs, but others do not.

When the armrests are at a 90-degree angle

When the armrests are at a 90-degree angle

They should barely touch your elbows. While resting your hands on the desk top or computer keyboard, the armrests should just barely touch your elbows.

Your arms will have to be positioned awkwardly if they are too high. You should be able to swing your arms freely. Resting your arms on the armrests while typing will place additional strain on your fingers and supporting structures.

The armrests of some chairs can be adjusted with a screwdriver, whereas others can be adjusted with a knob.

The lower portion of your armrests should be checked. Chairs with adjustable armrests are not available on all models. Whenever the armrests in a chair are too high or cannot be adjusted, remove them to prevent shoulder and finger pain.

Assess your resting eye level

Assess your resting eye level.

If you are working on a computer screen, your eyes should be level with it. Close your eyes, point your head directly forward, and slowly open your eyes while sitting on the chair. 

You should focus on the center of the screen and be able to read everything on it without straining your neck.  You can raise the computer screen’s level if you have to move your eyes down to reach it.

To raise a monitor to the proper height, you could slide a box under it. The computer screen can be lowered so that you can view it directly when you have to move your eyes up to reach it


Method 2 – Choosing The Correct Chair

chair is the right size for your body

Make sure the chair you choose is the right size for your body.

The majority of chairs are designed to fit around 90 percent of people, but those at the extremes may not fit. As there is no “average” person, chairs are made in sizes that can be adjusted to fit most people.

You may need a custom-made chair if you are extremely tall or extremely short. In the absence of a custom-made chair, you should purchase a fully adjustable chair so that you can adjust it according to your body type

Choose a chair with controls

Choose a chair with controls that can be easily operated while sitting

A chair with easy-to-operate controls will allow you to adjust your office chair to fit your body perfectly while sitting. By putting yourself in the chair, you can adjust all the pieces directly to your body.

Choose a chair with a height

Choose a chair with a height- and tilt-adjustable seat

It is very important that the height of the chair can be adjusted according to your body and needs when adjusting a chair. Sitting correctly requires tilt as well.

front edge of the seat curves towards the floor.

Make sure the front edge of the seat curves towards the floor.

With the curve along the edge, your knees will have more space and your thighs will be more comfortable. Additionally, the seat should not put pressure on the knees or the back of the thighs.

non slippery fabric chair

Non slippery fabric and breathable is the best choice for a chair.

When choosing a desk chair, consider these factors: you don’t want to get too sweaty or slip around a lot while working. 

Adjustable Height

Adjustable Height

Make sure your chair has a backrest that can be adjusted in height and angle to support your lower back. By adjusting the backrest to fully support your lower back, you can avoid pain and injury.

Armrests should be spaced evenly

Make sure the chair has a stable five-point base.

While sitting on the chair, it should have a five-point base that provides balance and stability. Depending on your preference, the base should be on wheels or casters.

Make sure your chair has adjustable armrests.

Make sure your chair has adjustable armrests.

While typing or working, armrests should never restrict your movement. Armrests that are adjustable can be adjusted to fit your body size and arm length.

How Important Is It To Have A Good Workstation?

Workstations should allow workers to sit comfortably and carry out their duties while allowing for correct position changes.

Workspaces have three contact points that affect worker posture: the seat, the worksurface (usually a desk or keyboard) and the floor. A good posture depends on two factors that can be adjusted.

The only thing you should not do is neglect to invest in a fully adjustable chair. A fully adjustable desk would be another option, and perhaps the best. This option, however, may not be practical due to its high price. For postural comfort, an adjustable chair and footrest are also effective (and cheaper).

How To Adjust Office Chair If It Is Fixed In Height?

You should be able to sit comfortably at your workstation once your chair has been adjusted for your height.

Workstations that are too low for you or do not allow you to move your legs freely are too low for you and should not be used regularly!
Workstations that are too high require you to elevate your arms to reach the work surface comfortably. Make sure your elbows are about the same height as the work surface by adjusting the chair height. Place your feet on a footrest if you cannot place them flat on the floor.
Both feet should be supported by the footrest, which should be adjustable. The footrest should be firm and flat so that the feet are kept flat.


Why is there a knob on the bottom of my office chair?

It is a knob that can be adjusted to increase or decrease the force needed to tilt the device. By using a tension tilt feature, you can decide how much force is needed to recline a chair.

How do the levers on my chair work?

To lock or unlock the tilt of the chair, some manufacturers use levers or paddles similar to those used for seat height office chair adjustments, or they use a single lever or rod.

Should you sit higher or lower at your desk?

Support your sit-to-stand movement by raising your chair
A low-level seat will cause contact stress and possible pain in these joints with prolonged use. A comfortable seat height is one at which you can easily place both feet on the ground and bend your knees and hips at 90 degrees.

how does my office chair not lean back anymore?

The recline lever of your office chair may be damaged or worn out if it no longer leans back. Check the recline lever on the chair upside down for damage or denting.

Do I need to adjust my chair if it’s too high?

It is correct to sit at a chair height when your feet are flat on the floor and your knees are slightly lower than your hips (with shoes on).

Is there a way to fix an adjustable chair that won’t stay up?

The most common solution for fixing an office chair is to use a hose clamp. It’s easy, cheap, and you can do it at home in just a few minutes – you don’t even have to disassemble the office chair. Although there are other alternatives, such as using a PVC pipe, hose clamps are more popular
