No tray for tools or hardware? no thanks. That backrest would mostly be in the way for me, I frequently push mine under a tractor or combine when switching work to the opposite side. I've been using the same round base Snap-on stool for 25 years at work and it's great, I don't even have a cushion on it. I have one of their square seats at home and hate it, the curved seat supports stick out the back and always hit stuff behind me in my crowded garage. Vyper would be a good stool for bench work in its taller form I suppose.
