Place the back rest portion over the top of the seat. Pull down all the way so that there is no gap between the cover and the seat. Once you have the cover on the backrest you can run the straps under the seat cushion attach straps and tighten. Place the cushion cover over the seat cushion and tilt the lean back towards the rear row. Tuck all access material in between the cushion and lean back to secure the cover and move lean back to desired location.
