Does your office chair keep on leaning forward?

Is it very uncomfortable and annoying?

Or worse, does it give you back and leg aches?

It should. Which is why you need to fix this problem immediately.

Unfortunately, when this happens, a lot of people tend to think their office chairs are done for good. That it’s best to replace it.

Hold up!

Your office chair isn’t broken. It just ran into a common problem that you can fix yourself.

Here, we’re going to show you the 3 ways you can fix your office chair that leans forward.

So let’s get to it!

Why Do Office Chairs Lean Forward?

To be able to fix a problem, you need to first know what the problem is.

This will help you get to the point right away.

Why do office chairs lean forward?

Well, with a fully adjustable office chair, this is actually an included feature.

It can improve posture, give better back support, and help blood flow in the legs.

So it’s a good thing.

But, it becomes a problem when it leans too forward and when you can’t position it any other way.

In this case, it provides the opposite of what it’s supposed to provide.

If you’re facing this problem, there are 3 reasons why you can’t lock the forward tilt mechanism.

The first one is rather simple. This is because the forward tilt knob is loose.

Another reason why this happens is that the forward tilt knob is stuck.

Finally, it happens when the forward tilt knob gets dislodged or broken.

Since it all has to do with the forward tilt knob, fixing the problem is easy enough.

Let’s take a close look at how to fix each problem.

The 3 Ways to Fix an Office Chair That Leans Forward

These 3 ways we’re going to mention will each solve one of the 3 possible causes of this problem.

1. How to Fix a Loose Forward Tilt Knob

It’s very easy to fix this problem. We’re not even sure if we can term this as “fixing a problem”.

Still, people that aren’t familiar with office chair adjustments need to know this.

All you need to do to “fix” a loosened forward tilt knob is to tighten it.

If it’s loose, it’ll lean the office chair forward because of the weight of your legs. If it’s tightened, the mechanism will hold the office chair in one position, despite the weight.

How do you tighten it?

Find the knob that handles the forward tilt mechanism. Once you find it, turn it clockwise.

That’s it! as easy as that!

One thing to note. Make sure your office chair has the right forward tilt for you before tightening. Maybe between 0 to 4 degrees.

If you feel you need more or less tilt, you can readjust by loosening the knob.

2. How to Fix a Stuck Forward Tilt Knob

What if the forward tilt knob is stuck?

No matter how hard you turn it, it won’t budge.

And since you can’t tighten it, your office chair will lean forward.

To fix this, you have to ask one question.

“Why is the knob stuck?”

The usual answer is because the knob’s mechanism is either very dirty or rusted or both.

To undo that then, you need to clean it out.

This requires a bit of disassembling since you want to get to the mechanism’s housing.

First, remove the seat. For some office chairs, this step isn’t necessary but it’ll make access to the housing a lot easier.

Below the seat is the housing. Again, there are some office chairs that have a covering for it, which you’ll have to pry open with a screwdriver .

Inside the housing, you’ll see all the knob and lever connections. Find the one that connects to the forward tilt knob.

This is the one you’ll need to clean.

To remove all the dirt, grease, and rust, spray WD-40  on it. Or you can also use a grease oil, like Lucas Oil Heavy-Duty Grease .

Once the dirt, grease, and rust are gone, the forward tilt knob will be able to turn freely. Allowing you to tighten it and get rid of the leaning forward problem.

3. How to Fix a Dislodged or Broken Forward Tilt Knob

How do you know if the forward tilt knob dislodges or breaks?

If you keep turning to tighten it but nothing happens, your office chair still leans forward.

To fix this, you’ll need to open up the housing.

Again, remove the seat, pry open the covering if there’s any, and find the forward tilt knob’s mechanism. It’ll be easy to find since it has a dislodged or broken pin.

During a dislodge, you can place it back yourself. All you need to do is fit the pin into its section. To avoid it getting dislodged again, you can put a clamp or glue it.

If the pin is broken, though, you’ll need to replace it.

In this case, it’s best to address the situation to the manufacturers. You can ask them for a replacement pin. They can even do the replacement for you.

If you want to do it yourself, make sure you follow their instructions carefully.


To summarize:

  1. Tighten the forward tilt knob if it’s loose.
  2. Clean the knob’s mechanism from dirt, grease, and rust to free it.
  3. Place the pin back into its section if it’s dislodged. If broken, you need to replace it.

So these are the 3 ways you can fix an office chair that keeps leaning forward.

If you’re facing this problem today, you can fix it within a few minutes. Don’t let this problem counter everything an office chair offers.
