We all sit in automotive seats without a second thought. YKK^® CONCEAL^® zippers, which hide the teeth (also called elements) and seams when zipped, as well as hook & loop fasteners, which are a type that holds together firmly once adhered, are even used in automotive seats. The work to cover a seat requires a great amount of strength, but work to set these covers is made easier by using zippers and hook & loop fasteners. Moreover, these hook & loop fasteners bring a power of expression such as luxurious designs and stylish curved lines.
