If the chair won’t stay up even when no one is on it, lay it on its side. If the plastic skirt covers the cylinder at this height, you will need to remove the skirt first. To do this, turn the chair upside down, push the retaining clip at the base with a screwdriver, and pull off the wheels, then the skirt. Slide the wheels back on.
Alternatively, scuff up this area of the cylinder with sandpaper. If the cylinder looks dirty or greasy, clean this off first.
If the clamp slides off, fasten it over a strip of rubber to improve the grip, or try the PVC pipe method below.
You shouldn’t need an exact measurement, but you can calculating the diameter from the circumference if you prefer to be precise.
The pipe does not have to be in one piece. It may be easier to work with in smaller pieces, although you can easily cut it yourself at home. One user reports using a tall stack of plastic shower rings instead of PVC pipe. These are even cheaper and easier to install, but they may not be sturdy enough to support your weight. Try at your own risk.
Wearing a mask or respirator is recommended while cutting PVC to avoid inhaling irritating particles. [4] X Research source If you do not have a vise or cutting tools, just leave the pipe intact and remove the chair’s wheels so you can slide on the pipe. In most cases, you can remove the wheel base by pressing a retaining clip on the underside with a screwdriver.
If you’re having trouble snapping the pipe on, saw it into shorter pieces and try again.
