If you connect your notebook computer to a large screen, at work or home, Floater is designed for you. It combines high technology with elegant styling. Close your MacBook pro, connect a keyboard, a screen and a mouse, and you have created a perfect working environment.
The Floater is machined from a single block of aluminum, which lends it great stability and optimum cooling power by spreading the heat around.
The two small panels around your computer are of minimal height and width, but sufficient to meet the product's two requirements; to hold your computer perfectly, and to let you set it up as easily as possible.
