Review: Great piston replacement - Reason for replacement - So rather than a failing piston or a squeaking one, the reason I replaced mine was because my new desk was much taller than my previous one leading to some discomfort and me looking like a child behind it, much to the amusement of my spouse. I needed to greatly increase the possible height of my chair and rather than replace it outright I thought to simply upgrade the piston. After some research into the travel of each cylinder and measurements of what I had, it seemed the average travel included on my premium basic chair (~$180) and my spouses' nicer (~$400) chair was about 3 inches. Installation - Aside from the more difficult than needed removal of the existing piston the installation was remarkably simple and sturdy. Just slip it into the wheel base and the seat of the chair (not forgetting the plastic shroud for the piston). The dimensions of my existing piston matched this one; 2 inch base and 1 inch piston diameter. Summary thoughts - The 6 inch travel on this is immense. The base height on my chair is about the same or maybe a little higher than the existing height of my chair at full extent. Note though, I wasn't looking for a direct replacement but a taller one instead, so this worked perfectly. In my pictures you can see the difference between the two pistons, the greasy one is the older, smaller one at full height compared to the lowest setting on the newest piston. I am 6' 1" and at the highest setting, sitting full back and upright, my feet dangle about 6" above the ground. Which is the height I'm writing this review at. :) While silly it works well for my desk height and I can lower it to pair better for a proper foot rest for ergonomic purposes. Hope this review is helpful for others seeking to do a similar replacement.
Review: Office Chair Fixed - This product worked perfectly to fix my office chair. This was a lot less expensive than buying a whole new chair. It’s a fairly simple process to change it out.
