The Cherry KC 4500 Ergo Wired Ergonomic Keyboard provides relief from tense shoulders, cramp or other unpleasant symptoms caused by incorrect posture. With its special design, your hands and arms take up a more natural position by themselves. This relieves your shoulders and back and your relaxed posture reduces stress. The extra-soft palm rest with memory foam prevents pressure points and lets you rest your hands comfortably. The three feet allow you to raise the front of the keyboard. This position is particularly comfortable when working in a standing position. Once you have become used to the special design, typing is the same as on any other Cherry keyboard easy and uncomplicated.
