Well designed, well engineered ergonomic seating enhances performance. An ergonomic chair can make a long day a lot easier and more productive. Back cushions should be used to modify an existing ergonomic chair or seat to conform to and support the body. These special supports promote relief to the back, neck, and shoulders through two major areas: 1) lumbar support, and 2) promoting proper posture. Remember, the one-and-only Interactive Keyboard System Designer will help you find the keyboard tray system perfect for your desk.
