A chair should be comfortable enough to not be distracting, but not so comfortable that you'd like to sleep in it. A desk should be large enough to support your work style. For me, that means space for a few large monitors, keyboards, and mice (I have a desktop and laptop, and sometimes bring the latter in for maintenance.) I also like space for notebooks of written notes, and area for someone else to work at if they're "visiting" while we collaborate. Without a large enough desk, I tend to start taking over other furniture for paper storage.
