Why buy a keyboard tray?
Articulating, ergonommic keyboard trays are the most important component for an office (or a home office) next to what workers are sitting in. For those who work at computers for a substantial amount of time, a Humanscale keyboard tray can provide serious protection from Carpal Tunnel Syndrome, neck pain, upper and lower back pain, and a variety of musculoskeletal disorders.

But keyboard trays offer more than just ergonomic advantages. They can make you more productive as well. For starters, placing your keyboard underneath your desk frees up your most accessible desk space - the area right in front of you. This space can be used for viewing documents and keeping everyday office items that much closer at hand. It also allows you to sit comfortably in many more positions while still staying on task.

The benefits of an ergonomic, adjustable keyboard tray are numerous, and the set up is made easy by Humanscale's user-friendly installation. For the best keyboarding system available, choose Humanscale.

Installing a keyboard tray into your desk system can be one of the easiest ways to consistently achieve a more ergonomic posture. Placing a keyboard directly onto your desk can be fine for some people, but more often than not, it encourages a less than optimal ergonomic posture- leading to wrist pronation, shoulder shrugging, and elbow extension. These postural faux-pas can lead to series ergonomic health risks, including carpel tunnel syndrome and neck pain.

Keyboard trays are extremely beneficial because most desks are not height adjustable, and the height of most desks does not match the optimal ergonomic position of your spine, shoulders, arms, and legs. If the desk is too high, your shoulders will shrug to place your elbows and forearms on your desk. If you desk is too low, your lower back will sag to to accomplish the same position. The root cause of this is the simple fact that your hands have to meet your keyboard to accomplish your work.

Keyboard trays offer adjustability, so rather than just accepting an uncomfortable position for your arms, you can find the optimal position for them whenever you sit down. In fact, ergonomics experts often say that an articulating (adjustable) keyboard tray is the most important component of an ergonomic office station next to the chair itself.

The keyboard platform allows you to type with your hands in your lap, a position that allows you to reduce upper body muscle activity and eliminate contact stress caused the desk's surface. This is known as the "neutral posture". The keyboard creates flexibility when it comes to the slope of your keyboard; this is important because the slope dictates your wrist angle. A slope that is too steep can lead to what is known as "wrist anchoring" - where the base of the wrist sits on the desk surface and the sharp angle causes stress in the carpel tunnel. This position can lead to carpel tunnel syndrome. An ergonomic keyboard tray has an adjustable angle that lets you change the slope as needed to move your wrist, or even position that keyboard at a negative slope. Studies have shown a correlation between the negative slope of the keyboard tray and the neutral posture of the hands. This effect has a significant impact on the upper body. In short, a keyboard tray is one the most affective tools for preventing carpel tunnel syndrome.

    How Keyboard Trays Promote a Neutral Hand Position Ergonomic Keyboarding Posture

    • Lower height of the arms reduces upper body muscle activity and range of motion

    • Promotes natural elbow and shoulder position

    • Significantly reduces contact stress on the elbows, forearms, and wrists

    • Prevents wrist anchoring and encourages with adjustable keyboard angles
