Is your office chair lift broken? Or perhaps you’re having trouble repositioning yourself in your sagging chair?

All of the pertinent information has been provided for your perusal right here. Take a look at these four simple approaches!

It’s true that working long hours is exhausting in its own right. This is why having a cup of coffee and a comfortable chair becomes increasingly crucial as the day goes on.

The sinking office chair is a common complaint when it comes to office supplies. This can lead to decreased productivity. Even the most up-to-date office chairs can become unsteady after only a few weeks of use.

The bright side, though, is that the problem can be solved quite simply. The most important thing is not to immediately toss your sinking chair.

The Anatomy of Your Office Chair

In order to fix your chair, you must understand how it works. Don’t worry, we won’t get too deeply into the weeds of technical jargon. When it comes to current height-adjustable chairs, there are two primary types of fluid power technologies: hydraulic and pneumatic.

Hydraulic or pneumatic, hypothetically, all office chairs sink during the course of their lifespan.

In contrast to the first, pneumatic chairs are built on compressible gases. Hydraulics can produce more power, which is why huge machinery often employs hydraulics. Most computer seats, on the other hand, use pneumatic systems.

Why does my chair constantly sinking? Probably because it has a pneumatic system. No fluid leaks are possible because the pneumatic technology is employed to manage light weight loads.

The pneumatic mechanism on your sinking computer chair may be a mystery to you, but if you keep reading, we’ll explain what you need to know to get a clearer perspective.

Moving on, let’s have a look at the chairs’ materials. In the end, you’ll know for sure “why my computer chair keeps sinking.”

Components Of A Pneumatic Chair

  • These chairs have three to five wheels each.
  • A backrest with soft padding
  • Adjusts the chair’s height with a lever on either the right or left bottom.
  • Adjustable height with pressurized air stored in this little gas cylinder

Components Of A Hydraulic Chair

  • Two chambers: a seat and a base
  • The compressed liquid is contained in one chamber, while the pressured gas is contained in the other.
  • a tube that runs across both chambers and joins them
  • A lever that can be used to adjust the chair’s height.

Why Does My Office Chair Keeps Sinking?

No matter how new or ancient the chair is, it sinks. You don’t have to worry if you acquired a new piece and it sank inside the first month. Even if the chairs are brand new, there is a simple reason why this can happen.

A sinking computer chair does not necessarily mean that it has already worn out. In simple terms, it signifies that you need to fix the chair’s raising mechanism because it isn’t operating any more.

How To Fix A Sinking Chair?

We spend a lot of money on our office chairs because we want them to be comfortable and ergonomic for lengthy workdays. A sagging office chair is something no one should have to put up with, regardless of how much money they’ve spent on it or not. Here are a few quick and easy solutions to your problem.

Method #1. Duct tape and a hose clamp

Temporary, Non-Adjustable, and Quick Fix are the main points.

Using duct tape and a hose clamp is a common DIY remedy or hack. In order to keep your chair from sinking, you can use this option.

For this method to work, a hose clamp with a diameter of 20 mm or 13/16 “-1-3/4” is required. It serves as a stop by being positioned at a specific height around the cylinder piston. The clamp is held in place using duct tape.

In the short term, this might work, but it’s not guaranteed to last. This means that before you know it, your chair will be falling again. Even if you are at home or at work, this is not a good look.

Method #2. Plastic spacer or pvc pipe

Temporary, non-adjustable, low-cost fix

Another way to prevent the cylinder from sinking is to use a piece of PVC or a plastic spacer. It is possible to wrap the plastic spacer around the cylinder piston by slicing it in half.

You’ll have to do extra work if you’re using PVC or an uncut spacer (taking apart the cylinder to slide on the spacer). This spacer, like the hose clamp, acts as a stopper and cannot be adjusted in height.

When you sit in your chair for long periods of time, the plastic can break or shatter. This is a major drawback. Consequently, this method may not be appropriate for usage at work.

Method #3. Changing the cylinder (recommended)

More or less, it costs around $30, it is a long-term remedy, and it is adjustable.

Hose clamp and spacer solutions are just temporary, do not allow you to sit at a specific height, and do not appear to be very professional. As a result, we recommend a cylinder replacement. Our recommendation if you’ve invested in a high-end office chair, such as one that includes a massaging function.

Your office chair will continue to look and feel like new for at least another six years if you simply replace the cylinder. Most desk chairs are built in the same way, so you can easily replace many of their parts.

A simple fix can be found if your office chair continues to sink while you’re seated. Your chair will be like new when you replace the cylinder.

Method #4. Components should be oiled

For mechanical components, you should check to see if you can feel any friction while using your chair or its lever. Due to the lack of lubricant, you should be happy that your office chair is sinking. Apply grease to your chair’s joints and see whether they’ll get any better with time.

What causes office chairs to sink?

There’s no such thing as a new or old office chair that doesn’t sink. If you recently purchased a new piece and it fell inside the first month, you don’t need to worry.

For some reason, even if the seats are brand new, this can happen. A sinking computer chair does not necessarily mean that it is worn out. This is merely an indication that the chair’s rising mechanism has failed, requiring repair.

Why do I have to perform maintenance on my chair?

Your workplace chair is subjected to a great deal of abuse. Things might become loose due to the constant weight and movement they encounter. At addition, sitting in an office all day might cause your chair to develop dirt and other debris, which could affect how effectively it functions.

How often does it need to be done?

In general, it is recommended that you undertake basic maintenance on your chair every six months. You can, of course, take care of your chair anytime you feel that it needs some attention. It’s possible that you’ll receive a note like this when you initially purchase your furniture, indicating when it’s time to have it serviced. Keeping track of when you last had your chair serviced and scheduling a reminder every six months in your calendar or on your phone will help you keep track of when it’s time for a checkup. We’ll talk more about how often cleaning is necessary later on in this post.

What should I do?

If you want to get the most out of your chair, you should take the following steps:

Cleaning your chair

Your chair requires regular cleaning. Whether your chair is made of fabric, plastic, vinyl, mesh, or leather, a weekly vacuuming will assist remove the filth, dust, and grime that can build up over time.. Only use vacuum attachments safe for your chair, and keep suction as low as possible to avoid any permanent stains or scratches. Weekly, use a clean cloth to wash down your leather and vinyl furniture, plastic, and the armrests and bases of your chairs.

Even with frequent upkeep, your office chair may occasionally require a more thorough cleaning. How you do this will be determined by the type of upholstery you have. “Go-To Guide for Cleaning Your Favorite Furniture” walks you through each cleaning procedure. These instructions and videos are available by clicking here. Spills and stains should always be cleaned up as soon as they are discovered.

Keep it rolling!

You’ll want to spend some time cleaning your casters while you’re at it. Every day, your chair’s wheels come into contact with dust, dirt from your shoes, the hair and fuzz in the carpet, and anything else they may come into contact with (like the crumbs from your lunch?). They’re constantly exposed to these things. This filth accumulates over time or gets trapped in the casters of your chair, making movement more difficult. When this happens, you’ll need to flip your chair over and remove the sludge.

First, remove any visible clumps of hair or dirt (if this really disgusts you, you can always wear gloves!). As a last resort, you can use compressed air to remove any remaining debris from the casters using an appropriate vacuum attachment. You may wish to spray WD40 on the casters after cleaning them to ensure that they continue to roll as smoothly as possible.

Tighten all screws and bolts

The screws holding the arms, seat, and back of your chair, as well as those in the chair’s mechanics, should all be tightened properly before you sit down in your chair. Turn the screws clockwise with the same tools you used to assemble them (the “righty tighty, lefty loosey” phrase comes in handy at times like these). If you overtighten the screws, it will be difficult, if not impossible, to make any adjustments without replacing the screw totally. So be cautious.

If you preserve your assembly instructions, you’ll be able to pick up a few extra parts for your furniture on your next trip to the hardware shop. In the event that something goes wrong, you’ll already have the necessary parts on hand.

Why does my chair continue to sink down?

The cylinder may need to be replaced if all of the nuts and bolts have been tightened and the chair still won’t stay put. First things to go out on office chairs are usually the gas cylinders. In the event that this occurs, you’ll need to determine whether or not you want to pay to replace the cylinder or simply buy a new chair.

Fixing your chair yourself can save money, and the process of replacing your cylinder is rather simple:

  • Make sure your eyes are well protected

You’ll need to wear eye protection because you’ll be dealing with various chair parts and a pressurized gas cylinder.

  • Find a place to work that’s big enough.

The area where you’re working should be protected against grease marks and scratches by using newspaper or plastic sheeting.

  • Cylinder can be removed.

Remove the cylinder by turning your chair over. To remove it from the chair, simply twist it until the chair base separates from the rest of it. You may need to use a pipe wrench or an aerosol lubricant to loosen it. Turn the base over and smash out the old cylinder with a rubber mallet once the cylinder and base have been removed.

  • Dispose of the cylinder

After that, replace the old cylinder in the chair’s base with a new one. Your chair should now be connected to the new cylinder and base, so you can sit back down.

  • Try out your chair

Sit down on your chair and check to see if it responds properly before adjusting the height to your liking.


If workplace chairs keep sinking, you don’t have to put up with bad seating positions and a miserable day. Follow these instructions to fix a chair that won’t stay up, and you’ll be able to work in comfort for the remainder of the day. The other benefit is that “how to fix office chair lift” will no longer be a source of frustration for you.
