The MotionGrey desk frame is for customers who want to enjoy the benefits of a standing desk and go the DIY route in building their desk. If you want to use your own table top or want your personally customized top for the desk, you may simply purchase a MotionGrey frame. This is the same solid steel frame that we use in our ergonomic desks, operated by the same powerful dual motors. It comes in options of black and white to help you better customize your desk.
