The Neutral Reach Zone
The Neutral Reach Zone is the area that can be conveniently reached with a sweep of the forearm while the upper arm hangs in a natural position at the side. (Sanders & McCormick, 1993)

Unlike older generation keyboard/mouse solutions, our platforms are designed to ensure that nearly all users are able to work consistently within their Neutral Reach Zone, and thus maintain a low-risk, sustainable posture.

Neutral Reach Zone

 

Option 1 - Track

Refers to the under-desk mounted track that the mechanism slides along. Measure the amount of flat space you have on the under-side (from front to back of your desk) to determine which track length best suits you. The longer the track you are able to fit, the farther underneath the desk you will be able to slide the platform. The track measures 5-1/2" in width and is available in seven lengths:

 

11" Track

For real small Desks at least 11" deep "from front to back"

14" Track

For real small Desks at least 14" deep "from front to back"

16" Track

18" Track
