What's your angle? Ergonomics is important—that's why this Atlantic Adjustable Portable Laptop Tray is designed with not only height-adjustable legs, but also lets you angle the surface 4 different ways and lock it in place. There's room for up to a 15 in. laptop, and mouse and laptop rests can be switched for left-handed users. When it's not on your lap, or your desk to use while standing, it folds down flat for storage.
