A pneumatic cylinder in office chairs controls the chair’s height with pressurized air. Unfortunately, many chairs’ cylinders malfunction after a few years, mostly because the seals have been too weakened to maintain pressure. To return complete functionality to your chair, you can purchase a replacement cylinder, which is almost as costly as purchasing a new chair. Do you want to know how to fix a sinking office chair?
How To Fix A Sinking Office Chair?
Use a Hose Clamp To Repair The Sinking:
First, slip the cylinder’s plastic skirt out of the way. The metal pipe attaches the wheels to the seat, known as the cylinder. Now properly clean the cylinder. Since this approach prevents the chair from being height adjustable once fixed, you must decide what height you want. Next, you should use a strip of rubber to wrap the area of the cylinder to give your hose clamp a stronger grip. Many chairs have a plastic tube over the cylinder to protect them from injury or debris. Slide the plastic tube down until you reach the metal cylinder under it. Make sure the chair is at the correct height once again. Then, by completely tightening the spinning pin, slide the clamp to the highest section of the cylinder.
Tighten The Pipe Clamp As Follows:
You would need to remove the legs based on the kind of chair you have. The piston will be revealed as a result of this. Start with the pipe clamp. Break two small shards of pipe safety foam and place one beneath the clamp and the other beneath the fitting. This would prevent them from quickly slipping on the piston. Next, choose the chair’s height and tighten the pipe clamp until it is securely fastened to the piston. When you lie down in your chair, you will no longer be able to move. This will temporarily fix your chair’s sinking problem.
Pneumatic Cylinder Replacement:
Since the pneumatic spring or the cylinder itself wears out with time, you must replace them in this process. You may either obey the manufacturer’s directions or take it to an authorized dealer who will do it for you. You will resolve the sinking dilemma by removing the cylinder, and you will be able to relax in a cosy chair again.
Form Of Jubilee Clipping:
Open the chair’s Jubilee Clip. Loosen the Jubilee Clip by spinning the screw counter-clockwise, so the belt end is free of the grip. At this stage, wrap the Jubilee Clip around the whole cylinder. Since you’ve closed it, don’t tighten it. Instead, let it go up and down the tube by leaving it loose. You must spin the screw clockwise to seal it, which can be difficult. However, tightening it would fully remove the sinking problem.
Plastic Spacers Are Used In The Following Ways:
Plastic spacers (PVC pipes) should be used the same way as hose clamps to repair a sliding office chair. Though many people use the PVC pipe option for added protection, first and foremost, precisely calculate the chair’s cylinder because the diameter of the cylinder would help you decide the amount of PVC pipe you’ll need. Remember to take the measurement when the chair is at the correct height for you, as it will not be adjustable later. Next, cut the tubing to the same height as you like it. When cutting the tube, wear safety gear because harmful particles are released when you cut it.
You can now have a pipe that runs from top to bottom by cutting it lengthwise. There will be a gap to snap the PVC pipe into the chair’s cylinder. When you sit on the seat after placing the pipe against the cylinder, the tube pipe will grab the seat and prevent it from going down. Now that you’ve tried out your office chair by sitting in it, you can relax and enjoy your office chair.
Why Does My Office Chair Tend To Sink?
Office chairs continue to sink regardless of how recent or old they are. You don’t need to be concerned if you’ve just purchased a new piece and it has sunk within the first month. This can happen to chairs for a simple cause, even though they are brand new.
One thing is certain: a sinking desk chair does not imply that it is already worn out. Instead, it indicates that the chair’s lifting mechanism has failed, indicating that you must repair it.
How Do You Repair A Leaning Office Chair?
We all like reclining office seats. They allow you to unwind while you work. When it leans back too far, though, it can be very risky. If yours has this issue, don’t ignore it or waste your hard-earned money on professional help. Instead, by following these basic measures, change your office chair to relieve pressure on your back and lower body.
Step 1: Look under the seat’s middle and see if your chair has a tilt stress control knob. If it does, move it to have more resistance when you’re reclining or lying back.
Step 2: After you’ve reached your desired height or level of reclining, release the stress knob. You can even tighten it if you want to add more suspense.
Step 3: If your chair has no reclining knob, search the tilt adjustment system for any problems. If you don’t have it, you may be unable to secure the back of your chair at a certain position. If the hydraulics in your chair is broken, keep reading to learn how to repair them.
Tightening the lever to lock the back can not always be the answer to your chair-leaning back dilemma. Instead, the concern may be with your sitting stance.
Is It Possible To Repair The Hydraulics Of An Office Chair?
Don’t get rid of the chair if the hydraulic system is down! It is possible to repair the gas cylinder and rebuild the lift mechanism in your office chair.
Remove the lift mechanism from your chair (which might take about an hour). A pipe wrench with a long handle, needle nose pliers, and someone to help you with this is needed.
Step 1: Take out the pipe wrench and cut the cylinder. If it doesn’t budge, enlist assistance.
Step 2: Measure the length of the gas cylinder from top to bottom until it’s finished. Measure the cylinder’s diameter, note the dimensions, and order a repair either or nearby.
Step 3: Press the tapered end of the cylinder into your chair seat to reassemble the new component. Oil the bearing and replace the previous washers on the piston rod. For a clean finish, secure the rod with the spring clip and brush away any excess oils.
Step 4: Raise the lift lever to the proper height to test your new patch. Pressure the gas cylinder into the retainer by bouncing it on the bench several times.
What Happens If Anything Goes Wrong While Fixing A Sinking Chair?
You must be cautious when calculating the precise pipe size you need to use. However, you might make additional modifications if the seat needs to be higher:
- Lift the seat to the height you want and make the calculation.
- Take another pipe and make a label on it.
- Cut the pipe and put it next to the snapped pipe on top of the cylinder.
Conclusion
With these easy and inexpensive methods, you’ll be able to fix your sink problems in minutes. It would be best if you complimented yourself for saving the world and resources by repairing a sinking office chair. To change the chair’s height in the future, loosen the pipe clamp, slide it to the correct spot, and tighten it again.

Executing the instructions to get the best possible result closely is important. Additionally, remember that this repair would completely kill your office chair’s ability to change its height, so use this solution only if removing the cylinder isn’t a choice.
