Herein disclosed is an improved seat having a detachable tray member which is formed with spaced outward flanges. The seat comprises a seat cushion, a seatback mounted on the seat cushion and a pair of armrest units respectively mounted to both sides of the seatback. At least one part of each unit is formed at its inboard side with a straight groove.
