Two months ago I finally bought this chair and have to say: "I'm impressed." It's the BEST chair I've ever sat on. Even my back pain has improved or (almost) disappeared.

Clear instructions. The manual included a QR code that, when scanned, took me to a video of the chair's assembly process. From all that work (it isn’t a lot of work to assemble the chair, but just keep going with the story here) of assembling the chair. This chair can provide more comfort. Love it.

I have a Racing Model chair from 2020. The Drifting lift cylinder was the replacement part I was told I needed. It works great, and following a few steps, it was easy to install. However, I do want to point out that it is a good bit taller than the original part, they do not swap out exactly.
