Nitro Concepts S300EX Fix

Hello,

I purchased a Nitro Concepts S300EX from you in 2020, I was wondering if there is a warranty for this product? Or if you could send me a replacement gas canister?

The case canister has protruded through the base of the chair meaning it now drags on the floor and wobbles while sitting at my desk.

Any help or advise would be much appreciated!
