This is a very old picture of my home office - I am guessing this is 2010 or so.
My desk is a HON office desk. I have two of them side by side and it takes up most of the room. The pictures are misleading - I can fit three monitors on the desk and still have a ton or room on both sides. In fact, when I pay bills at the desk I move the chair over to the right and use the empty desk space there.
Something else that works well is dining room tables. Don't laugh - they are both long and wide and can fit anything you need. During the summer my upstairs home office is super hot so I work from downstairs on a laptop and an extra monitor.
Come to think of it... We had a crappy little typical back yard table and chairs in the back yard. We tossed them and bought a kitchen table... We bought it used in a local yard sale group for $20 - it's huge and heavy and sturdy and works great...
