It's everything. Sometimes I try to work from coffee shops or sitting in a bad chair (one of those folding ikea chairs) and it's awful. Can't get ANYTHING done. In fact, I think my single best purchase for my business was a Herman Miller Mirra chair. Keeps my butt and back happy. If you're thinking about anything other than your work (like you're cold, hungry, or uncomfortable), then for sure, it's going to impact your productivity.
