• Concave keywells are scooped into a bowl shape to reduce hand and finger extension and relax muscles.|Separating the keywells positions the arms at shoulder-width to keep wrists straight and perpendicular to the home row to reduce abduction and ulnar deviation.|The keys are arranged in vertical columns (rather than staggered) to reflect your fingers' natural motion better.|The two keywells are “tented” to moderately raise the thumb side of the hand. Tenting puts you in a more neutral “handshake” posture and reduces the stresses caused by forearm pronation. Choose from one of three heights depending on your preferences.|The integrated palm supports reduce stressful bending of the wrists and provide a convenient place to rest your hands when you are not actively typing. Add the new premium pads for even more support (AC360PP Sold Separately).|The thumb clusters include frequently-used keys such as Enter Space Backspace and Delete to redistribute the workload from your relatively weaker overused little fingers to stronger thumbs.|The Advantage360 may look big but it has a smaller footprint than most keyboards because we eliminated the numeric 10-key so you can place the mouse closer to your body reducing painful “over-reach”.|Functions keys are located in the number row and accessed via the Fn Key for reduced reach and enhanced portability.
