Does your desk work for you? It's probably the most important component of any home office, so take a hard look. My desk, a tall Ikea secretary, was in fine shape, but it wasn't suiting my new needs. I required more surface area to work and eat lunch, so I replaced my secretary with a sleek, crisp Parsons desk from West Elm. Bonus: It only took me about 10 minutes to assemble—instant transformation!
