Vinyl is an ideal material for upholstery for a variety of reasons. Vinyl gives you the look of leather and has greater durability. Unlike leather, vinyl is easy to clean, requiring just a wipe with a damp cloth. The one drawback is that vinyl can crease. However, the creases are easy to remove with a simple method.
Plug in a hair dryer and turn it on to low heat. Direct the hot air onto the creases.
Smooth out the creases with your hand as you apply the heat. For stubborn creases, run a rolling pin across the surface of the upholstery to flatten the vinyl. Raise the heat on the blow dryer as you do this.
Continue to apply the hot air from your blow dryer onto the vinyl until the creases have disappeared.
Switch the temperature of the blow dryer to cool air to help set the fabric in this new smooth position once all the creases are gone.
