The Vevor under-desk keyboard tray is designed to create a more ergonomic and organized workspace for home or office use. Its 25" x 9.8" tray fits most standard keyboards and mice, while the adjustable height, swivel, and tilt help you find a more comfortable typing position. A smooth sliding mechanism lets you tuck the tray away when not in use to free up desk space. The built-in wrist rest adds comfort and helps keep the keyboard in place when tilted. It is made with an MDF board and Q235 carbon steel frame for sturdy everyday use.
