With a sharp increase in computer usage over the past decade, a vast majority of the United States population generally uses some form of a keyboard to type on their computer at some point everyday. This is especially true for the workers that are considered to be full time employees whose average work day consists of 8.4 hours, according to the American Time Use Survey Summary. With the increase in working such long hours typing and sitting in front of a computer screen, ergonomic keyboard trays are becoming more popular and more common as the number of daily computer users rises. A keyboard tray is a piece of ergonomic computer furniture that is designed to hold your keyboard and mouse and is generally used to move the location of such input devices, either moving to a fixed position or being adjustable to the users specific needs. Ergonomic keyboard trays are made to comfort your wrists while you are typing in order to take the strain off the muscles in your wrist, which are used the most when you work continuously at a keyboard.
The benefits that result from buying and installing a keyboard tray are numerous. An adjustable keyboard tray is one of the many ergonomic devices you can utilize that can help prevent common injuries and conditions resulting from daily computer use. Repetitive Strain Injury (RSI) is the most common and most often diagnosed computer-related injury people develop. Perhaps the most well known repetitive stress injury is Carpal Tunnel Syndrome, which effects your hands, wrists and forearms. Carpal Tunnel Syndrome leads to paresthesias, numbness, and muscle weakness in the hand. Frequently repeated tasks, such as typing on a keyboard or using a mouse, are the main cause for these types of ailments, and installing a high quality tray is a surefire way to reduce tension in your shoulders and arms.
Keyboard trays are designed to install under a computer desk, with the ability to pull out the keyboard from under the desk when it is needed and put the keyboard away when not at the computer. With a keyboard tray installed under the desk rather than on the desk itself, this allows for more free space and a cleaner desk area. Proper adjustments are needed in order to ensure healthy posture and positioning of your wrists. Make sure the keyboard tray is not too high, or you will strain your shoulders by having to raise them in order to lift the arms up. If it is too low then it will result in bent wrists when you are typing. Distance should be adjusted that the forearms and floor remain parallel to each other and elbows rest close to the body.
Most importantly, keyboard trays are created to give the end user the most comfortable typing experience possible while providing healthy typing at the same time. When working strenuous hours on end everyday, it should not have to be any harder by using improper or uncomfortable devices which can be ultimately eliminated with a keyboard tray. They also come in stylish looks and designs perfectly suited to any working environment whether you are using one at home or in your work office. If spending multiple hours in front of a computer is part of your everyday routine, a keyboard tray will be a worthwhile investment for your home or office; especially in the long run.
