Type more naturally with the ERGO K860 Wireless Split Ergonomic Keyboard from Logitech. The ERGO K860 has been engineered to improve your typing posture, provide more wrist support, reduce strain, and even reduce the muscle activity of your upper trapezius (center of your back). To accomplish this, the ERGO features an atypical shape and design to achieve proper alignment and relaxation of your hands, wrists, forearms, and shoulders. The K860 is molded with a convex curve in the middle of the keyboard, right where the keys themselves are split and angled away from each other. Logitech also provides an adjustable, 3-layer wrist rest that places your forearms just above the keyboard to help reduce wrist bending. The ERGO K860 is both Windows and Mac compatible, connecting to your computer of choice using Bluetooth 5.0 LE technology via an included USB Type-A Bluetooth receiver.
