Why does my office chair lean to one side?

So, why does your office chair lean to one side? It could be due to an uneven floor, unleveled seat cushion, wrong positioning of wheels, or loose screws of the chair.

There can be many other reasons as well.

Here is a list of some of the mains reasons why your office chair leans to one side.

Uneven floor

The first reason could be the uneven floor. If the floor is uneven, it can cause your chair to lean. This will happen especially if your floor is made up of tiles or wood.

The seat cushion is not leveled

When you sit on a chair and keep leaning towards one side, this could be because your seat cushion is not level with the backrest. If this is the case and you check that there are no loose screws in the chair mechanism, then you may find that it’s time to get a new office chair.

Wrong positioning of wheels

Your office chair leans as a result of the wrong positioning of wheels under the frame. You might need to adjust them again if they are unevenly positioned due to any reason (including shipping defects).

Improperly positioned wheels can disturb the balance of your chair.

Wrong practice of sitting on a chair

Another reason why your office chair leans to one side could be the wrong practice of sitting in the chair. Many people tend to sit in the chair without putting their feet on the ground, leading to one side of the chair being more weighted than the other.

You push back a lot

Pushing back your office chair while it is upright can lead to leaning if you lean too much, causing that side of your body to take more pressure and hence making you lean towards that direction. This could be as a result of sitting for long hours at a time or due to weak legs which cannot hold up against gravity anymore.

Caster whee needs adjustment

The caster wheel of your office chair may need adjustment if it leans because it is misaligned with its frame. Adjusting them accordingly will help eliminate this issue.

The backrest is not leveled

If you use your chair for prolonged hours or your backrest is not leveled with your seat cushion, then this could be one reason why your office chair leans. If so, consider getting a new chair because the other reasons listed above may no longer apply in such a case.

Loose screws

Checking for loose screws can also solve the problem of an office chair leaning if that was its cause. However, adjusting the caster wheel will require taking apart your entire office chair which requires setting up again after adjustment.

How do I stop my chair from leaning to one side?

You can solve the problem of an office chair leaning to one side by adjusting your caster wheel, leveling the seat cushion and backrest with a spirit level, cleaning up your floor, or replacing your chair.

If your office chair leans to one side and there is nothing wrong with it mechanically, then you’ll have to change the way you sit in it.

Here is what you do: First of all, if you push back a lot when sitting on your chair, fix that by sitting upright and not leaning or pushing back too much.  

Secondly, don’t lean towards the backrest but keep your spine straight as it can cause your body weight to lean to one side after long hours.

Thirdly, adjust your seat cushion level with the height of your backrest so as to balance everything out.

If none of these work for you, then get a new office chair since yours is probably damaged or past its use-by date.

What is tilt tension adjustment?

The tilt tension adjustment is the knob on the right side of your office chair, which controls how much you lean back with each movement.

If you turn this knob to a higher setting (counter-clockwise), it makes it harder for you to lean back and hence would discourage leaning back in the chair. You will also be required to apply more pressure while leaning back and thus preventing both from leaning too far backward or forward.
