Purpose and fitment

The presented backrest is designed as a rear seat component for the left side, ensuring it fits the factory bench layout in the Mercedes W166 series. The construction is prepared for installation in place of the original backrest, which facilitates maintaining the correct passenger position and the proper operation of the folding and locking mechanisms.

The backrest belongs to the Seats and benches group, meaning it is an integral component of the seating system, and its replacement has a direct impact on the ergonomics and functionality of the rear passenger cabin.

Material and finish

The surface of the backrest is made of imitation leather, which ensures a consistent look with other upholstery elements in versions equipped with this type of material. Imitation leather is a practical solution for everyday use – it is easy to keep clean, resistant to typical dirt, and allows for quick surface refreshing with standard upholstery care products.

The choice of material and the stitching style are adapted to the interior design of the Mercedes W166, ensuring that the backrest replacement does not disrupt the visual continuity of the rear bench. The appropriate structural rigidity is also maintained, which is essential for stable back support for passengers.

Function in the rear cabin

The left-hand rear seat backrest is responsible for a comfortable passenger position and proper load distribution while driving. As part of the seating system, it works in conjunction with the seat cushion and other bench segments to create a uniform surface. Proper fitment of this component is important both for comfort and for maintaining the factory functionality of the rear passenger zone, including the potential folding of the backrests to increase cargo space.

For users who are upgrading their interior or restoring it to a near-factory condition, this original rear seat backrest is a solution that avoids the compromises associated with fitting aftermarket parts of uncertain geometry.

Characteristics of the used component

The offered component comes from disassembly, meaning it is a used part that retains the functionality intended by the manufacturer. Such elements are popular choices for interior repairs because they allow for an economical replacement of a damaged backrest while maintaining the vehicle's original specifications. A used rear seat backrest is particularly useful in situations where there has been mechanical damage, wear, or localized destruction of the upholstery in the rear bench area.
