I had one that I used for my marking tools, smaller rulers, embellishments, rotary cutters, etc. each had its own drawer. I replaced it with a unit that has deeper drawers. Guess what, it's harder to find stuff now because each item no longer has its dedicated drawer. Live and learn.
You can get a really nice office chair at Staples (or another office supply). Lots of sales and clearance. Just make sure it's adjustable and has no arms or removable arms.
