Branch Furniture Ergonomic Chair Pro | Needs New Cylinder

Brand new Branch Furniture Ergonomic Chair Pro! I used another one for the photos of it out of the box, but this is a brand new office chair. I was sent this thing by the company, but ended up having a problem with the cylinder being absurdly squeaky. I tried to solve it with white lithium grease, but no dice. The company sent me a whole other one shockingly enough, so I just swapped the cylinder and base from my chair I already built with the new one that was sent. They told me I could do whatever with the leftover chair, so I figured I'd sell it and fund other projects I want to work on. I would imagine that if you are interested in this chair, you'll want to buy a new cylinder, or take a crack at re-greasing it. https://www.branchfurniture.ca/products/ergonomic-chair-pro (They sell a "tall cylinder" option on their site for $45, so that could work well.) Please let me know if you're interested.
