Proper ergonomics are one of the best ways to maintain a healthy back and since we spend so much time in front of a computer or at our offices, I felt posting this might help some of you.
Ergotron, maker of Ergonomic design devices, has an ergonomics calculator that I use for our office workstation setups. If you know your height you can get started planning your more ergonomic working environment. This includes the all-important keyboard height and chair height.
Happy typing.
