Office chair: pneumatic removal

>>937052
the pneumatic cylinder is the bit that attaches the seat to the base so if you can find something suitable to replace it then yes.

Just drill a hole in it

It isn't a "pneumatic" function.. It is an hydraulic function.

this. drill a small hole, drain the hydraulic fluid. no more lift

Are you a midget?

Actually it is a pneumatic function, as the cylinder uses a gas, which compresses when you lower the chair.
There is actually two cylinders, a nitrogen gas spring, and a cylinder with a valve that allows gas to enter/exit.

When you lower the chair, gas escapes, when you raise it, the nitrogen spring lifts the chair drawing air in.

This wouldn't work as a passive hydraulic system because hydraulic fluid isn't compressible.

Lol, actually I'm 1.85, unfortunately the desk is very low and I can't jerk under the desk if I go higher

I love how it always comes down to masturbation on 4chan...

It sounds like you have a leaky check valve in the top of your cylinder. Drilling a small hole in the bottom would do the trick, but you'll have to be careful due to the pressure on the compressed inner cylinder. For best results, extend the cylinder as far as possible before venting it.

Thanks! Is there any video on how to drill that part? I'm a bit afraid of doing it

On some gas lift cylinders there's a bleed cock you could keep open.
Or, just pointing this out, you could put something under the desk feet to raise the desk up

The only way to remove the pneumatic function is by breaking the pneumatic function, or removing it and then you're practically building a new chair base.

It's always about masturbation. The others are just liars.
