The Sculpt Ergonomic Desktop has a uniquely modern design and an amazingly comfortable feel. It"s built on advanced ergonomic principles, incorporating a split keyboard layout to help position the wrists and forearms in a natural, relaxed position, a cushioned palm rest to provide wrist support, and a domed keyboard shape to reduce wrist pronation. The mouse is also designed to maximize wrist comfort with its unique ergonomic shape. And it also includes features like the Windows button which gives you convenient, one-touch to access to the Windows 8 Start screen, so you’ll be able to stay comfortable and productive all day long.
