Question for professional chair engineers

[bainbridge]

Can I store an office chair upside down without fear of hydraulic fluid going everywhere?

Also will regular upside down storage mess up the delicate equilibrium and turn my chair into a sinker?

We've just moved and I'm working from home on the dining table during the day and storing the office chair in the garage after work, the garage is chockablock and I'd like to store the chair overnight just inside the garage door on a big box.

Thanks

Thanks for the replies, I'll start storing it upside down overnight. My employers will replace it if need be but I was just wondering.
