Sinking chairs are a common problem, especially in households with children or pets. The good news is that there are a few easy ways to fix a chair that keeps sinking. In most cases, you will only need a few simple tools and materials that you likely already have around the house. With a little bit of time and effort, you can have your chair feeling like new in no time!
What Causes a Chair to Sink?
One of the most common causes of a chair sinking is a poor or worn-out gas lift. The gas lift is what allows you to adjust the height of the chair, and over time, it can start to wear out. This will cause the chair to slowly sink down, no matter how much you try to adjust it. Another common cause is a problem with the tension spring. This spring helps to keep the chair stable and in place, but if it breaks or becomes worn out, it can cause the chair to sink.
There are a few things you can do to try and fix a chair that keeps sinking. First, check the gas lift and make sure that it is not damaged or worn out. If it is, you will need to replace it. Next, check the tension spring and see if it is broken or needs to be replaced. Finally, make sure that both the gas lift and tension spring are properly adjusted so that they are providing enough support for the chair. If all else fails, you may need to replace both the gas lift and tension spring.
How to Fix a Sinking Chair
If your chair keeps sinking, there are a few things you can do to fix it. First, check to see if the chair is level. If it’s not, adjust the legs until it is. Next, check to see if the chair is too heavy for the gas lift. If it is, try removing some of the weight from the chair. Finally, if the chair is still sinking, you may need to replace the gas lift.
Adjust the Tension
One of the most common reasons a chair starts to sink is because the tension in the gas lift cylinder has been released. This can happen over time as the cylinder wears down, or it may happen if the chair is accidentally hit or dropped.
Unfortunately, there’s no easy way to adjust the tension on a gas lift cylinder. You’ll need to replace the entire cylinder in order to fix the problem. This is a fairly easy process, but you will need to have a new gas lift cylinder on hand before you begin.
Replace the Gas Cylinder
If your chair uses a gas lift to adjust its height, chances are good that the gas cylinder is causing it to sink. Over time, the internal pressure of the gas cylinder can decrease, which makes it harder for the chair to stay at a certain height. Replacing the gas cylinder is usually pretty easy and only takes a few minutes.
Check the Chair Base
If your chair keeps sinking, the first thing you should check is the chair base. If the base is bent or damaged, it will need to be replaced. In most cases, this is a fairly easy repair that can be done with a few simple tools.
If the base of your chair is in good condition, the next thing to check is the gas lift. The gas lift is what allows the chair to adjust its height. If the gas lift is damaged, it will need to be replaced.
Once you have checked the base and gas lift, if your chair still keeps sinking, it is likely that the problem is with the seat itself. The seat may be worn out or damaged, and will need to be replaced.
There are a few things you can do to fix a chair that keeps sinking. You can try tightening the screws, using pliers to bend the metal back into place, or adding a shim to the base of the chair. If your chair is still sinking, you may need to replace the gas lift.
