How To Fix A Sinking Desk Chair

Have you ever asked yourself what makes your desk chair to sink? Some of the common problems include a defective gas strut and the failure of the adjuster to engage properly. You do not have to run up and down looking for an expert to assist you fix a sinking chair because you can do it yourself. In our discussion below, we have provided you with simple tips on how to fix a sinking desk chair.

Sinking Desk Chair

To begin with, you have to assemble tools you may require while fixing the chair. Some of the tools you should acquire include the following:

• Regular hammer or rubber hammers with a piece of cloth for wrapping the hammer so that you do not end up damaging the chair

• Measuring tape or any other measuring tool that will help in finding the optimal length of the tube

• Cutting tool that you will use to cut the polypropylene pipe

• A hexagonal key or socket that you will use to remove your seat and its backrest ensemble

Note: Most seats use the 4mm hexagonal screws but not all of them. Therefore, you have to check with your  chair before getting the right hexagonal key for the same.
Once you have the required tools for the job, the first step will be to remove the seat and its backrest by unscrewing the screws connecting the seat to its metal support system. Although this operation is not mandatory, it allows for easy working on the different parts of the seats from the strut to its housing.

After removing the seat and backrest, hold the chair upside down and tap the metal support very vigorous to remove the black plastic and telescopic dust protections. Then place the chair upright and return the seat gently without pressing so that you measure the distance between its gas cylinder and the end of the seat very accurately (while fixing my office chair I noticed this distance was 130mm). This does not mean that the distance must be 130mm since every chair has its own specifications. Measure this distance (in my case 130mm) beginning from the thick side of the polypropylene pipe as accurately as possible.

If you want to lower the office seat, cut a smaller sized piece (I had to use 85mm instead of 130mm). This implies that when someone sits on the chair, it will fall from 130mm to 85mm. Moreover, you can add on the tubes strength by fixing zip tie loops at the circumference of the pipe. The next thing will be to press the cut down the chair’s strut and then fix the same tightly.

With the tube tightly fixed in the strut, tie the zip ties to form a loop and then wrap with a bit of force to fix it around the tube of the chair tightly. One of the loops should occur where the PP tube meets the strut cylinder while the other should be at the uppermost part of the tube where it meets with the seat. Thereafter, return the plastic dust protections removed earlier on. The last step will be to insert the strut’s tip in the housing of your seat with the help of the red arrow found in most of the seats but not all and then press hard so that the housing ridge fits in the gap lying between the strut and the PP pipe end. Up to this point, your seat will be ready for use once again.

How do you fix a chair with a higher weight limit?

In the event that you have a chair with higher weight limit, you will have to follow these simple steps in fixing it as fast as possible. To start with, set the chair height according to your preferences and then flip it so that the wheels face you. After that, you will remove the cover of the chair if there is any. The next step will be to drill a small whole right where the shaft meets the base of the chair. Ensure that you use a drill with the same size as the screw. Lastly, you will insert a screw into the hole and then tighten it properly. Once you do it well, the chair will not sink at all no matter the weight
