Check the gas lift

If your office chair is sinking, the first thing you should check is the gas lift. Over time, the gas lift can lose its tension, causing the chair to sink. To fix this, you will need to replace the gas lift.

Check the base

If your chair is sinking, the first thing you should do is check the base. Over time, the base can become worn or loosened, causing the chair to sink. To check the base, look for signs of wear or looseness. If you see any, tighten the base using a wrench or pliers.

Another possible cause of a sinking chair is a broken or damaged gas lift cylinder. The gas lift cylinder is what allows you to adjust the height of the chair. If it’s damaged, it can cause the chair to sink. To check for a damaged gas lift cylinder, look for leaks. If you see any, you’ll need to replace the cylinder.

Finally, if your chair is sinking because of a broken spring, you’ll need to replace the spring. To do this, remove the old spring and install a new one in its place.

Check the casters

The first step is to check the casters. If one or more of the casters is defective, it can cause the chair to sink. To check the casters, remove the chair from the base and try rolling it across a flat surface. If the chair doesn’t roll smoothly, or if it wobbles, one or more of the casters is likely defective and will need to be replaced.

Check the mechanism

If your chair is sinking, the first thing you should do is check the mechanism. Most office chairs have a gas lift that allows you to adjust the height of the chair. If this gas lift is not functioning properly, it could be causing your chair to sink.

To check the gas lift, sit in the chair and adjust the height so that your feet are flat on the ground. Then, try to raise yourself up slightly off the seat. If the chair goes down instead of up, then the gas lift is not working correctly and will need to be replaced.

If the gas lift is working properly, then the next thing you should check is the springs in the base of the chair. Over time, these springs can weaken and cause the chair to sink. To check the springs, simply sit in the chair and see if it sinks down lower than usual.

If your chair has both a gas lift and springs in the base, then it is likely that one of these components is not functioning properly. In most cases, you will need to replace either the gas lift or the springs in order to fix a sinking office chair.

Check the arms

If your chair is sinking, the first thing you should check is the arms. Most chairs have adjustable arms, so you may be able to fix the problem by simply tightening the screws. If that doesn’t work, you may need to replace the arms.
