Laptops are great, because you can use them on a train, in an airport, wherever. It's the benefit of always having your data with you and often these days, access to the Internet, online Email etc.

However, despite the flexibility, most of us use our laptops far more in the office and/or at home and it's in these locations that we can make a difference to our health.

If you take a look around on the Internet, you'll find many independent sites explaining the optimal working position. For example: Cornell University Ergonomics Web. A Prop-Forward will take care of the screen positioning leaving you free to arrange the separate mouse and keyboard as you wish.

This is a diagram representing the bad posture adopted when using a laptop on a desk.

In fact, our simplified diagram does not show the curvature of the spine caused by bringing the head down towards the screen.

Interestingly, many "laptop stands" that simply angle the laptop by a few inches do very little to improve the situation.

This diagram shows how the Prop-Forward brings the screen to the correct position.

Once the screen is in the correct position, everything else falls into place. The posture adopted by the user is correct and a normal keyboard and mouse provide the best operational comfort.
