What Is The Twist Knob Underneath An Office Chair?

The ‘tension‘ feature is a knob that allows you to change how much force is required to tilt the device. Therefore, a tension tilt feature effectively lets you choose how much effort is needed to recline in a chair and how far you want to recline.

This knob is also known as the tilt tension knob or the tension knob. This feature allows you to adjust the force required to tilt or rock your office chair. While reclining, you can adjust the backrest’s resistance by turning the knob.

The twist knob is typically found on the front of the chair, underneath the seat. There should be a plus (+) sign and a minus (-) sign for directions. Turning the knob clockwise will increase the recline tension, making it harder to tilt, while turning it counterclockwise will decrease the tension, making it easier to tilt.

Several standard adjustable parts can be found under office chairs. These features allow you to customize your chair to fit your needs and provide maximum comfort while sitting.

Tilt tension knob

One of the most common adjustable features is the tilt tension knob, which we discussed in the previous section. This feature allows you to adjust the resistance of the backrest while reclining or rocking.

Seat height lever

This lever allows you to adjust the height of your chair by compressing or removing air from a gas cylinder inside the chair. Adjusting the seat height is essential for achieving a comfortable and ergonomic sitting position, as it allows you to sit with your feet flat on the ground and your knees at a 90-degree angle.

Tilt lock

Some office chairs also have a tilt lock feature, which allows you to lock the chair’s tilt at a certain angle. This can be useful to maintain a specific posture while sitting. For example, if you are working on a task that requires you to lean forward, you can lock this chair feature to prevent it from reclining.

Back height

In addition to these standard features, some office chairs have other adjustable features, such as a back height adjustment mechanism, which allows you to adjust the height of the backrest. This can be useful for providing additional support for your lower back and helping to maintain good posture while sitting.
