The only reasons I gave it 4 starts for sturdiness and comfort:
The base should be a bit larger for more stability at full height extension.
The seat portion could be larger and maybe a little thicker at the front so you dont feel like you are about to fall off if you lean forward.
Overall happy, and its beyond easy to assemble.
Allen head screws for attaching the seat are really cheap. As soon as they get snug, the provided allen wrench strips right through the screw. (good thing is you cant overtighten)
