The Microsoft Sculpt Ergonomic Keyboard for Business is built for ergonomic comfort and efficiency. In order to provide optimal comfort the keyboard has a contoured keyset, cushioned palm rest, palm lift and adjustable keyboard legs. This is all to allow for a more natural, relaxed positioning of your arms, hands and wrist while typing. The spacebar is larger than that found on standard keyboards, and is split with a backspace bar on the left-hand side. This is intended to allow you to type more quickly and maximize productivity.
