Why Office Chair Won’t Stay Up

We should find out the causes before getting to know how to fix an office chair that won’t stay up.

We need to understand how an office chair goes up and down with the control of the little knob and levers under the seat to understand why it keeps sinking.

A gas lift cylinder is a piston mechanism where there is a chamber filled with nitrogen gas.

To lift the chair up, the air flows to the chamber and, with an airtight seal, remains compressed there. The gear lever then locks the height of the seat.

To lower it, the air is released from the chamber below to flow slightly above the piston. The lever is used again to lock the desired height.

A chair keeps sinking because the seal inside the gas cylinder becomes weak and lets the nitrogen gas out.

The cylinder is no longer able to sustain the weight of the chair with or without extra weight on it. This leads to the chair to drop to the bottom no matter how much you set it.

Experiencing this issue can have a variety of consequences. For example, if you use the chair in this manner, you may experience neck stiffness as a result of trying to compensate for the lack of adequate height.

Therefore, if you have a sinking chair, you should address it as quickly as possible.
