Automobile upholstery

A typical leather-upholstered car seat.

An automotive upholsterer, also known as a trimmer, coachtrimmer or motor trimmer, shares many of the skills required in upholstery, in addition to being able to work with carpet.

The term coachtrimmer derives from the days when car bodies were produced by manufacturers and delivered to coach builders to add a car body and interior trimmings. Trimmers would produce soft furnishings, carpets, soft tops and roof linings often to order to customer specifications. Later, trim shops were often an in-house part of the production line as the production process was broken down into smaller parts manageable by semi-skilled labor.

Many automotive trimmers now work either in automotive design or with aftermarket trim shops carrying out repairs, restorations or conversions for customers directly. A few high-quality motor car manufacturers still employ trimmers, for example, Aston Martin.
