Purpose and fitment

The presented three-seater bench represents the right part of the rear seat row in the Mercedes W639 model. The construction is prepared for operation within the factory mounting system, ensuring proper positioning relative to the floor and interior side panels. Using an original component from the Seats and benches group allows for maintaining compliance with the manufacturer's design, both in terms of ergonomics and safety.

Construction and upholstery material

The bench is finished with leather upholstery, which translates into higher durability compared to textile materials. Leather makes it easier to keep clean while simultaneously providing a characteristic, more prestigious interior look. The rear seats in this configuration are designed for intensive use – the structure supports stable back support for passengers and even load distribution across the entire width of the bench.

Function in the interior layout

As the right part of the rear three-seater bench, this element helps form a complete row of seats in the passenger space. The proper profiling of the seat and backrest promotes comfort during longer journeys, and the leather finish improves the perceived quality of contact with the seat surface. Using an original Mercedes solution helps maintain the consistency of the stylistic line with other cockpit elements and door panels.

Practical application and installation

This rear bench is intended primarily as a replacement for a worn or damaged seat module on the right side. Utilizing an original product facilitates installation at factory mounting points without the need for interfering with the body structure. In practice, this means shorter service times and a lower risk of issues with fitting the component to the existing interior layout.

Benefits of choosing an original leather bench

By choosing this bench, you gain a leather finish in the Luxury version, which raises the overall standard of the cabin and improves passenger experience. The original Mercedes origin helps maintain the vehicle's value and reduces the risk of dimensional discrepancies or installation problems. This solution is particularly beneficial for comprehensive interior restoration or returning the car to a configuration close to factory specifications.
