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.

But now I'm realizing it: This chair wants to make me healthy! Lumbar cushions, neck cushions... Things you don't find on a normal office chair! Comfortable, supportive... unusual! My body has always been more "hunchback at the top, hollow back at the bottom"! Now the chair is trying to correct both!

Steel frame construction. I would recommend this chair and buy it again.
