Turn the new seat cover inside out and heat the underside of the fabric for a couple minutes using a heat gun or hair dryer. Leather and vinyl expands and stretches when exposed to heat.
Turn the seat cover right side out and place the seat cover onto the seat. It's usually easiest to place it over the front of the seat first, then pull the back part over the back portion of the seat. This must be done quickly, while the seat cover is still warm and pliable.
Use a hair dryer to warm the fabric as you stretch it around seat.
Staple the seat cover in place
Please be very careful with heat as to not melt or burn seat cover
