Large, too comfortable desks do not work for me well. Instead I prefer to use a smallish desks that impose limitations on available space. In this way, I get in the zone. I also tend to care about my customers more when I bound to some physical restrictions. In simple words, I become more empathetic to other people's ups and downs when I feel the pain of this world. Even when such limitations are artificially imposed on my working environment.
