This product from DXRacer is a great all-rounder. I wouldn't hesitate to recommend it.

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 upgraded my chair because I was experiencing back pain from a previous chair. Everything in the box is well packaged and doesn't fell like a cheaper knockoff brand at all. his chair has helped my back tremendously. Everything else is top notch and I highly recommend if you are sitting for long periods.
