Want to utilise the space under your keyboard and get ride of all the little things that accumulate around your desk at the same time? Check out this Grovemade keyboard tray ($100) in black walnut. Flip your keyboard up and you have space for all kinds of little desk things—like notes, batteries, tacks, and whatnot—that never seem to have a home. Flip your keyboard down, and it just looks like your keyboard has some nice wood trim. They do a trackpad tray, too.
