Description
We offer a full line of durable keyboard and mouse platform options created to meet the needs of a wide variety of individuals, workstations and office environments. Each of our platform options is designed to ensure that users type and mouse within their Neutral Reach Zone, thereby encouraging safe, sustainable working postures.
By combining one of these platform options with one of our award-winning mechanisms, you will create the most non-intrusive, intuitively adjustable keyboard support available. All of our keyboard and mouse platforms are made of phenolic, an ultra-strong, remarkably thin (1/4") composite that`s non-toxic, durable and easy to clean.
Humanscale 300 Curved Keyboard Platform: This platform supports most "ergonomic" keyboards, such as the Microsoft Natural Keyboard, and is compatible with any of our mouse platform options. Dimensions: 20-3/4" W x 9-1/2" D.
Keyboard Systems - In many ways, a keyboard support is the heart of an ergonomic workstation. As reach and vision drive posture, an articulating keyboard system allows the user to sit in a healthy, neutral posture through bringing the keyboard and mouse to the user. A well-designed articulating keyboard system offers protection from carpal tunnel syndrome, neck and back pain and other musculoskeletal issues. Since 1995, Humanscale has been the leading manufacturer of articulating keyboard systems and today sells more than all other manufacturers combined.
Effortless Use - Humanscale patented keyboard systems have effortless height and angle adjustment. Promoting negative tilt keying, the keyboard platforms will not go into a positive tilt.
Durability - Humanscale keyboard trays are solidly anchored to any work surface, and shape to specific user needs. Hypoallergenic Gel palm supports offer height and durability, and are designed to be compatible with human skin.
Customization - Humanscale offers three negative-tilt keyboard systems, from 5G to our latest 6G, which combines easy dial-a-tilt and height adjustability with the strongest, most stable arm on the market. Humanscale keyboard supports come in many different configurations, including left/right customization, to support any user need.
Design Story - An ergonomically designed keyboard is essential for every workstation. Ergonomists agree that the healthiest typing posture is one that allows the wrists to maintain a neutral or slightly pronated posture - straight or bent at a slightly downward angle. For that reason, Humanscale designers created our keyboard systems to allow the keyboard to positioned anywhere from 0 degrees to a -15 degree angle.
A decade of ergonomic research shows that using a negative sloped adjustable keyboard tray maximizes the time spent working in a neutral hand, wrist and upper body postures. These postural benefits can’t be achieved by just using a keyboard on a height-adjustable work surface." - Dr. Alan Hedge, Cornell University
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.
