Common Knobs Under An Office Chair

I would point out that the knobs we have mentioned in this article may not be part of your office chair. There are hundreds of designs and types of office chairs on the market.

However, since we’re talking about the most common ones, it’s likely your office chair will have one, or even all, of these knobs.

Last but not least. There might be the same mechanics in your office chair, but it is located somewhere else. The chair might also be shaped differently.

Tilt Tension In Chair

Have you ever felt the need to recline in your chair for a short break from your computer?

The tilt tension of the office chair now allows you to do so!

You can adjust the tension of the chair by turning this knob. The knob must also be lowered to reduce the tension, causing the office chair to rock. To increase the tension, turn the knob the other way if you want it to lock at a certain position, such as a little bit reclined.

Since the knob has a + and – marking, you know which way to turn it.

Using a Channellock or a wrench, you can adjust the knob if it’s hard to turn.

Under the seat, toward the front, is where the chair tilt tension is most commonly found. The knob is usually the biggest one. Nevertheless, some office chairs provide tilt tension at the side of the chair, either as a knob or even as a crank.

That’s why this is a great office chair mechanic to have because you can determine the tilt that’s most comfortable for you.

Adjust Height

There is nothing more annoying than selecting an office chair that is too short or too tall for your height by mistake or lack of knowledge.

Several hours of sitting on it will result in your legs and feet feeling a lot of pressure. I have noticed this more often than not.

The height adjustment knob is another of the most common office chair mechanics. With this knob, you can individually adjust the chair’s height.

For easier access, the height adjustment knob sticks out of the side of the seat. The knob in the middle is usually the one that sticks out if many knobs are sticking out.

Pull the knob while adding weight to make the seat sink if you want to lower the height. You can heighten it again by pulling on the knob, but this time, do not add weight. It’s that simple.

The mechanism works by attaching the knob to a hydraulic or pneumatic metal shaft below the seat. This shaft allows the seat to move upwards and downwards.

Eventually, the metal shaft and knob cease to function, which is something that always happens over time. Office chairs always sink when sat upon. Learn how to fix this problem if it happens to your office chair by clicking here.

With this knob, you don’t have to worry about whether your office chair is too short or too tall for you.

Adjustment Of Back Height

If the height of your office chair is fine, but the back support is too high or too low for you, how can you adjust it?

Is your office chair’s backrest bulging to accommodate your lower back, but it’s too high or low for you to relax?

For that, there is a knob, too!

This knob is located under the backrest. After you release tension, adjust the backrest to the height that is most comfortable for you. Adjust the knob until you find the right position.

In newer chair models, the height adjustment is usually controlled by a ratchet rather than a knob.

In this case, you can adjust the backrest by pulling upwards while placing your hands on the base of the backrest. As the height pawl locks onto the ratchet with each pull, you’ll hear a clicking sound.

Slide down the backrest after pulling it all the way up until it no longer clicks.

Ratchets have fixed heights, so use them at your own risk. You can adjust the knob’s height to suit your needs.

However, the ratchet technique is easier to adjust.

Adjustment Of Seat Angle

In order to keep your spine upright and have good posture whilst sitting for hours in your office chair, it’s best to maintain an upright position with an arched back.

Even if your office chair’s backrest bulges, the seat angle still plays an important role in ensuring an upright posture.

The first knob sticking out from the front controls the seat angle adjustment.

By turning this knob clockwise, the front of the seat will dropdown. Similarly, if you turn it counterclockwise, the dropdown will be on the back of the seat.

Office chairs usually allow the seat to be tilted forward or backward by 6° or 3° respectively.

Adjust Seat Depth

In addition to promoting good posture, the seat depth adjustment also helps with lumbar support.

It also ensures that your legs’ circulation isn’t slowed down.

Having your knee touch the seat might reduce blood circulation if there is pressure on the knee. Also, keep the back of your knees from being too far from the seat to avoid backaches.

It is best to leave a distance of at least 2 fingers between your knee and the seatback.

Adapting the seat depth on your office chair is easy if it has one.

This knob is the only one on the left side, so you won’t have a problem finding it.

When you lift the knob, the seat will move inward and outward.
