Pickup trucks are designed to accommodate large cargoes but have limited capacity when it comes to cargo protection. Covering delicate cargoes with simple cloths or plastic is not recommended since the weather and other harsh external conditions are unpredictable. Thus, some pickup owners rely on tonneau covers. A tonneau cover is a car accessory that acts as a protective cover of the truck's bed.

Sometimes called the truck bed cover, the tonneau cover secures the cargo through its fasteners, which resemble snaps or mechanical roll-down devices. With a tonneau cover, the truck bed appears to have a flat cover that smoothly runs through the entire truck bed up to the top of the tailgate. One advantage of the tonneau cover is that it allows motorists to safely haul the cargo. A truck bed cover keeps various elements such as rain and intense sunlight from damaging the cargo as well as the truck bed. To endure all these elements, the tonneau cover is made of durable materials. The most commonly used is heavy-duty vinyl with a rib-like system to support the fabric. A snap was popular back then, but motorists today are not that fond of it anymore since this type requires drilling and using permanent adhesives.

There are different types of tonneau covers based on design and functionality. Some motorists want covers that suit the look of their vehicle. Tonneau covers also make trucks look sportier. Some of the types of tonneau covers are the snap down tonneau cover and roll-up tonneau cover. The snap down tonneau cover is ideal in any kind of weather condition. The roll-up tonneau cover, on the other hand, is best for those in areas with cold weather. This is because its material can adapt to the low temperature and the contour of the cover across the truck bed.
