Why does my office chair keep sinking?
Office chairs usually have a spring mechanism that is filled with air, the more pressure you apply to the seat the lower it will get, but remember when applying pressure to pull the handle. If your chair keeps sinking with little to no pressure applied then it could be a sign that your chair is no longer useable and may need replacing.
What to do when my office chair sinks?
You can try to fix the mechanism and try to salvage what is left of your office chair. You can also get and use a different chair in the office. When office chairs sink it is time to take a look at the chair and see if you can salvage it, if not then it is a sign to get a new chair.
