The pad may be comprised of two parts, one in the seat portion and one in the back portion, with a space therebetween to provide the fold line. Flaps extending completely across the seating arrangement are provided at the remote ends thereof and overly a portion of both the back portion and the seat portion. Tab portions are coupled to the flaps at the sides thereof and flexible straps, which are detachably coupled together, are provided on the tab portions.
