A tray on a table frame is a tray table – especially if the tray can be detached and used to convey the items you need to carry.
The metal Tray Table is a multi-functional piece of furniture that can easily be adapted to fit your needs. When the tray top is in place, it can be used as a bedside table or coffee table, and when the tray top is removed, it becomes a regular tray that can be used to carry items.
