People who work from home for long hours all experience the same problem - Backaches/butt pain etc. This can really harm your productivity eventually as you will be irritated and annoyed, causing you to fidget more (Not being able to stay in one position and focus on your work). Personally, I think it is important to invest in a good comfortable chair if you are serious about working from home.
What are some other productivity tips you guys know?
