Be as comfortable as you can be while typing. Wherever you are. The Microsoft Sculpt Comfort Desktop Keyboard uses BlueTrack technology to track your mouse on virtually any surface. The wireless connection for this keyboard and mouse set also works up to 30 feet away, meaning you really can sit wherever is comfortable in your office space – because the 2.4GHz wireless connection won’t force you to be uncomfortable. The keyboard also aligns the position of your arms, wrists and hands for a more natural, healthy posture.
