Office chair Knob and Lever:

Office chairs come in different shapes and sizes. Manufacturers design the chair in such a way that almost everyone can use it comfortably according to their height.

That’s why the chair Manufacturers use a tilt tension knob and height adjustment lever. By using these two functions, a chair can use most of the person.

Sometimes, people buy these chairs without having the knowledge of how they work or what these knobs and levers are for. We will explain the Tilt tension knob and seat height adjustment lever. Let’s find out what they do and how to use them.

1. Tilt Tension Knob:

Before knowing about Tilt tension Knob, let’s discuss tilting. Tilting is basically allowing yourself to rock back and forth and also recline while sitting.

Adjusting this function is related to your height and weight. If you are taller or heavier, you will need a tighter tilt tension.

On the other hand, if you are a short or lighter person, then you will need less tight tilt tension. The tilting Knob helps you to just find the sweet spot.

You will find the knob at the bottom of your Office Chair. Every good and ideal office Chair has this knob, which will allow you to adjust tilting while you are sitting on it.

You can adjust to increase or decrease the required force for tilting. This feature will allow you to decide how much you want to recline on your Office Chair.

What does the tilt tension adjustment knob do?

The tilt tension knob allows adjusting the tension or firmness of the backrest while reclining. For example, if you are rocking on your chair, with this adjustment knob if you tighten the knob it will increase the resistance of the rocking motion and vice versa.

How to use:

  • Find or locate the knob at the bottom of your office chair. 
  • Rotate the knob clockwise to tighten.
  • Rotate the knob Anti-clockwise to loosen.
  • Keep adjusting until you find a sweet spot which provides perfect tilt tension for you.

Also, if you sit on your chair for long hours daily, this feature will reduce your chances of developing back pain.

2. Seat Height Adjustment Pneumatic Lever:

Seat Height adjustment is one of the common features that can be found in every office chair. While sitting on a chair, almost all of us have the tendency to adjust the height so that we can sit comfortably.

If you are looking to purchase a chair, always check that the chair has this option or not. Having this feature enables us to work for long hours and make us productive.

How To Use: 

  • To lower your seat: Find the adjustable height lever(it’s usually on the right side of a chair or at the bottom), then place your body weight on the chair, and push the lever down, then it will gradually lower the seat height.
  • To raise your seat: place your body weight to your feet and then pull the height lever up, then the chair height will gradually start to rise.

Why is it important: Sitting down on a chair properly is important. Generally, the best way to tell the proper seat height is to simply sit on the Office chair and adjust the height lever until your two feet touch the floor completely, and your knees are at a 90-degree angle.

If you are not using this method to properly sit on your chair, you might feel discomfort to your back and knee. It will ruin your back posture.

In the long run, you might suffer from back pain. When you are sitting on a chair, always try to adjust the seat height to your comfort position or if you don’t know what’s your comfort position, then simply try the method we mentioned above.

Benefits of Having These Adjustable options:

1. Increases Comfortability:

Fixed chairs don’t have these tilting and height adjustment options. So, they aren’t comfortable for everybody. Maybe it will be comfortable for certain people but won’t be for most of them.

If you are a taller person or shorter than the average, you might find it very uncomfortable to sit on them and work for hours upon hours. These two options can help you adjust the tilt tension and seat height to sit more comfortably.

2. Increases your Productivity:

Long hour job can be overwhelming as well as frustrating. While you are working for a few hours, you might want to recline or adjust the seat height to make you comfortable.

If your office chair doesn’t have these features, then you might have to go out and be relaxed as your sitting experience will not be comfortable. This might kill a lot of time while you are working, but the chairs with these options will help you stay productive for long hours.

3. Help You Sit Ergonomically:

These features will help you to sit properly and with correct posture for long hours. Thus you will get the ergonomic benefits and will be able to avoid physical and health issues that arise from prolonged sitting habits.
