The NEW DETRAY is a tray that takes the shape of the arm of your sofa or of most unstable surfaces to turn them into a stable, useful space where you can leave your glass or cup without fear of spilling your drinks all over the place. It is made of plywood birch strips placed on a piece of fabric, making it possible for the tray to adapt to the arm of the sofa, whatever its size, and also allowing you to fold it in half or roll it up in any way you wish.
