I bought one in August of 2022 and it is now sinking as a sit in it. Will you replace it?

Yes thay will replace it . why do?you whant something that may work.

How to I get a replacement for my failing piston?

The piston is called a 'gas lift' - this is the product you are looking for.

Does it come with Cylinder removal kit

No, there is not a removal kit included. I would recommend watching the video on the product page, a 'how-to' remove and replace existing cylinder. I used a regular hammer and not a short-handled sledge hammer like featured in the video and did not have any issues.

the base of my chair is 45mm, not 50mm. Do you make a tube that will fit my chair?

I don’t work for the company. I’ve bought and am familiar with the products but have not run across that.
