Cushions were generally large, upholstered in leather, and solid enough to function as a seat back then, but all furniture has gradually shrunk over time. Cushions are now considered upholstery items. Even replacing one seat with near-original upholstery is a time-consuming and costly endeavor. A set of aftermarket seat coverings is the finest solution. They are simple to install, come in a variety of styles, and, most importantly, are simple to replace.
