An apparatus for covering a bench seat may have a seat cover with an installed configuration in which the seat cover is secured to the bench seat via a plurality of anchoring elements. The seat cover may have a support portion securable to a support member of the bench seat, and a backrest portion securable to a backrest member of the bench seat. The support portion may define a support recess, and the backrest portion may define a backrest recess. The backrest portion may have two rear backrest panels that define an intermediate backrest gap that is spanned by a rear flexible strap. Other anchoring elements may include one or more flexible connectors secured to a rigid feature of the vehicle, blocking member connectors extending between adjoining portions of the support portion and the backrest portion, and/or draw string elements that tighten the seat cover around the bench seat.
