The Type Tray seeks to protect your lap (and nether regions) from the heat emitted by your laptops. The tray is made of 100% industrial wool felt, which acts as a heat dissipater.
What separates this tray from the others, is the gorgeous, retro-styled typographical design laser-etched on its surface. The makers claim that the tray is made through an eco-friendly manufacturing process, and can be safely recycled too after its utility is over.
The Type Tray costs a super-expensive $100 (Boo!), and is currently out of stock at the moment.
