What Won’t Office Chairs Stay Up?

There is something wrong with your chair if it keeps sinking whenever you sit on it. In most situations, the underlying culprit lies in a malfunctioning cylinder.

A cylinder or a gas lift helps support users’ weight and stabilize the chair. This explains why you have some bounce feelings when taking a seat because much air is compressed within the cylinder. When a worn-out cylinder cannot fully sustain the pressure, the chair won’t stay up properly. Besides being worn, the problem of a gas lift derives from cheap and degraded-quality materials.

If you put too much load on it, surpassing the allowable maximum, which results in a broken piston mechanism. The frequency of abrupt sitting behaviors is also conducive to the height adjustment system’s failure.  

How To Fix An Office Chair That Won’t Stay Up?

Our post equips you with four viable methods of fixing a chair that cannot stay up. These include replacing a gas lift, installing a specialized kit, using a hose clamp and duct tape, and relying on a plastic gasket.

Replacing a gas lift

As mentioned earlier, a damaged cylinder is one of the leading causes of a wrong chair. If you encounter this problem, remove a faulty gas lift before installing a new one. Avoid purchasing dirty cheap products because they are notorious for bad quality.

First, you must overturn it and remove the piston from the wheelbase. Then, use a hammer to give your cylinder a solid hit so the connection between your chair and its lift starts to lose.

To break this connection, clamp a wrench forcefully on the actual cylinder. Amid this practice, try to pull and rotate the cylinder away. Repeat this process for some time, and install a new gas lift immediately when you take it out.

Installing a specialized kit

The best option is a Saver kit from Herman Miller. You must attach this tool to the spacers to support the seat better. You should measure the desired height and snap sufficient rings onto the piston.

Use a wrench set to tighten them slightly until you cannot rotate them anymore. Suppose the ring is prone to damage. Buying some spares as an alternative in an emergency is advisable.

A positive aspect of this approach is that you fix the chair in one position, making it easier and more effective.

Using a hose clamp and duct tape

A hose clamp and duct tape often prevent a chair from sinking. Pinpoint an area where you intend to hold a hose clamp and wrap the duct tape around it. Rotate the clamp’ screws clockwise with the help of a screwdriver.

If you want to smoothen the surface, rely on sandpaper. Finally, take a visual examination and test your chair by sitting on it.

Using a plastic gasket

The eventual solution is to use a plastic gasket to maintain the chair’s height. Under this circumstance, you must cut one side of the gasket or pipe by following its length.

Then, please attach it to the metal cylinder carefully until it fits. If the left space is too large, continue cutting the plastic gasket into smaller sections.
