If you work at home, you need proper ergonomics.

Many people work at home, and they say they can afford to purchase ergonomic equipment.

You can't afford not to! Not every product will be expensive, but no matter how much you spend, it will be cheaper than rehabilitating from an ergonomic injury. Get the best workstation you can – and spend as little time as possible sitting at it! Remember, the body was meant to move.
