In this article, you will be able to learn how to fix a sinking office chair. We offer two kinds of methods as a solution to your problem with your sinking office chair. These are the PP Water Pipe Method and the Hose Clamp Method.
PP Water Pipe Method
Before proceeding to your task, you will need specific tools to perform this particular method accurately. If you have them all, then you’re good to go!
Tools
-
- Hacksaw
- Oil
- Polypropylene (PP) water pipe. The following measurements should be:
- Length (130 mm) – Anything you have in your house is okay, as long as it fits the optimum height of your office chair
- Diameter (32 mm)
- Thickness ( 1.6 mm)
- Measuring tape
- Rubber Head Hammer
- Optional: Regular Hammer covered with a piece of cloth to avoid damage to the chair
- Wrench or Screwdriver
Step #1: Remove the seat from the base
In this step, the materials you will need are either a wrench or screwdriver and a rubber head hammer to remove the office chair. If there is no available rubber head hammer in your tools, do not worry, you can still fix your chair. Just provide a regular hammer and cover it with a cloth to avoid damaging your chair.
Place the office chair upside down and then start loosening the screws. Next, with the use of the hammer, remove the seat very gently by hitting the attached metal part
Step #2: Cut the PP water pipe
The specific materials needed here are your measuring tape and cutting tools. Before doing this step, be cautious while doing this procedure. We suggest that you wear the appropriate gear that will protect you from being hurt, like hand gloves and safety glasses.
Measure the length of the PP water pipe and cut it with your hacksaw. Ensure that your tube is secured and correctly in place to prevent any uneven edges
Step #3: Attach the PP water pipe to the extendable cylinder
Now that you did steps 1&2, it’s time to place the PP water pipe by attaching it to the extendable cylinder. Measure the cylinder’s width, length, and circumference that will be a perfect match to the specific pipe. When you are trying to get the measurement of the diameter, it can be the same or a little larger than the cylinder.
To insert the strut, you need to push the PP water pipe on the cylinder and don’t leave any gaps between the cylinder and the strut. The pipe should be just right, not too tight, and not too loose.
After this step, try sitting on your office chair to test the sturdiness. If it still sinks, we suggest that you should remove or add the length of the pipe for better adjustment of the height.
Hose Clamp Method
Here are the materials you will need for this method.
- Duct tape
- Jubilee clip
- Screwdriver
- Hose clamp
Step #1: Slide the plastic skirt of the chair’s cylinder
If you will notice, your office chair has a metal pipe that connects the wheelbase to the seat. When you look under your chair, you will see a plastic tube over the cylinder.
If you’re confused about why it’s there, the primary purpose of the plastic is to protect the metal from dirt or damage. Once you find the plastic skirt, you have to remove it until the cylinder is exposed.
Step #2: Adjust the chair to a height that you prefer
The hose clamp method gives long-lasting results as long as you check the desired height. Be sure that you know the exact height suitable for you again since this method provides permanent results and cannot be changed afterward.
To make sure that you chose the right height, here are some guidelines that you can follow:
- The seat of your office chair should have the same level as your knees when you stand.
- Adjust the height through the cylinder
- Turn the chair upside down and remove the plastic skirt
- Push the retaining clip at the wheelbase; we suggest that you use a screwdriver in this part
- Once you adjusted the chair to your preferred height, slide the wheels back on
Step #3: Wrap a 2cm hose clamp around the chair’s cylinder
Use a jubilee clip when applying the hose clamp. Loosen the screw and carefully take out the belt end. Wrap it around the cylinder, but don’t tighten the clamp just yet.
Step #4: Make sure the metal cylinder fits before tightening it
After you wrap the hose clamp around the metal cylinder, you need to ensure that it fits perfectly before you tighten it. Once you’re sure that the clamp is stable, tighten the grip. For a sleek look, wipe off any grease or dirt from the cylinder before you wrap it with duct tape.
Conclusion
You made it up to this point on how to fix a sinking office chair. Now, you can sit back, relax, and easily work on your fixed office chair.
