For drivers of convertible cars, a Tonneau cover is a valuable accessory to protect the unoccupied passenger seats and cover any luggage or other personal property that is left there when the car is unattended.

The three principal uses of the Tonneau cover are to keep the heat in a convertible car, to prevent the buffeting that occurs as a result of air being caught in the passenger compartment and thereby increase fuel economy, especially when the car is driven at high speed and, finally, to conceal any items that are left in the car when the driver is not there. When a passenger is being driven in the car and the Tonneau cover is not required it is easy to detach and store in the boot of the car until it is next needed. It is possible to use a Tonneau cover as an alternative to a soft top or hard top.

A Tonneau cover will normally be made from leather, vinyl or similar material. It is manufactured to the dimensions of the convertible vehicle whose unoccupied compartment it is to cover. The Tonneau cover stretches across the whole of the passenger compartment of the vehicle and has a zip fastener which enables all but the driver’s seat to be securely covered.
