A thermoforming apparatus for fabricating seamless vehicle seat covers includes a clamp assembly for clamping and holding a thermoplastic sheet, a heater for heating material held by the clamp assembly, and a female cavity mold having a base section and a backrest section. The mold has an internal vacuum passageway formed therein, and also includes an external vacuum port for connecting to a source of vacuum. The vacuum port is in fluid communication with the internal vacuum passageway. A vacuum conduit connects the vacuum port to a vacuum source, by way of an electrically operable valve in fluid communication with the vacuum port. A method of thermoforming a seamless vehicle seat cover, and a seamless vehicular seat cover, which is a product of a thermoforming process, are also included.
