To get to the metallic cylinder, you need to remove the protective plastic covering, this involves you removing the wheel of the chair first by unscrewing the holding screw. Slide off the plastic cover, then reattach the wheel.

You need to adjust your chair to a preferable height that will be convenient for working on your work desk. If the chair sinks even when no one is sitting on it, you can lay it sideways on the floor to be able to adjust the height.

Attach the jubilee clip

Ensure the chair is still held at the preferred height then push the clip back upwards, the area where the duct tape is. The duct tape improves the grip of the clip and ensures that it keeps the chair in position. Tighten the jubilee clip by firmly rotating the screw on it.

Check your chair

After attaching the jubilee clip and duct tape the chair should be now stable without sinking. If the clip slides down, it is either the screw is not well tightened, or it needs a better grip.

You can make use of a rubber strip to improve the grip of the clip.

As effective as this method can be, it comes with its downside. You will not be able to adjust the height of the chair, this is why you need to set it to your preferred height. If you need to adjust the height, you have to unloosen the screw of the clip and readjust the height before screwing back.

Use a PVC pipe

The PVC pipe is another good way of keeping your sinking char afloat. The pipe has to be slightly larger than the metallic cylinder to be able to slide it over it.

Get the right measure of the cylinder

This method also involves you sliding off the plastic covering off the metallic cylinder. You need to get the right measurement or an estimate of the cylinder. You can easily do this by making use of a ruler to horizontally measure the cylinder, also you need to adjust the sinking chair to a preferred height and measure the length of the cylinder.

Use the PVC pipe

The pipe to be used for this task has to be able to fit over the cylinder of the chair and be able to cover the entire length of the cylinder. You need to cut the PVC pipe lengthwise, to do this you need to make use of a vise. The vise helps you to get a neat cut on the pipe and ready it for fitting over the cylinder.

Fit the pipe over the cylinder

The pipe needs to be snapped onto the cylinder; this can be a bit difficult especially if the preferred height is a bit long. To make the process easier, you can cut the pipe into small pieces that can be snapped on the cylinder.

The chair should be fit for use now. In this method as well, the height cannot be adjusted, this is why it is important to set the height at a preferred position before completely snaping the PVC over the cylinder.

If the height is too tall or shorter than needed, you can either cut some length of the pipe or snap-on another small piece of PVC.

Safety requirement

PVC pipes are known to contain harmful compounds, especially when the particles are exposed. This method involves you cutting a PVC pipe. To ensure your safety while carrying out this task, you should have a protective mask on to prevent you from inhaling harmful particles from the pipe.
