Purpose and fitment

The backrest has been designed specifically for the rear left section of the bench in Mercedes W163 series models, ensuring it retains factory lines and seat ergonomics. Its placement in the rear zone of the cabin makes this element significant for both passenger comfort and the aesthetics of the entire row of seats.

The grey color scheme makes it easy to match with the original upholstery, and the partial leather finish allows for the maintenance of the brand's characteristic combination of functionality and a refined look.

Construction and partial leather material

The backrest is manufactured using partial leather technology, combining leather surfaces with other upholstery materials. This construction provides:

• stable back support for passengers in daily use,
• easier cleaning compared to full fabric upholstery,
• a consistent, factory-original interior look characteristic of Mercedes models.

As a result, the backrest performs well both in cars used on a daily basis and in vehicles being prepared for resale, where maintaining the original character of the cabin is essential.

Condition, origin, and installation benefits

The item comes from dismantling and is offered as a used original component, which allows for maintaining compatibility with Mercedes' factory design solutions. Choosing an original backrest from the same model series minimizes the risk of fitment issues and reduces the need for upholstery modifications.

In practice, this means that with proper installation, you can achieve an effect close to the factory standard – both in terms of alignment with the seat cushion and the lines of the side panels and other rear bench elements.

Comfort and functionality of the rear bench

Replacing the backrest in the rear left section of the bench has a significant impact on the comfort of second-row passengers. A properly selected element:

• restores proper back support on longer journeys,
• eliminates discomfort resulting from the wear of the old backrest,
• improves the overall appearance of the rear interior.

The grey partial leather finish helps maintain a uniform cabin look, which is important both for users who value aesthetics and for those preparing the car for sale.

Interior expansion and modernization

If you are planning a comprehensive repair or modernization of the rear bench seating area in your Mercedes and need other elements from the same group, such as backrests, seat cushions, or headrests, check out the available parts in the Mercedes Seats and benches category.

For larger cabin changes, it is also worth considering selecting other upholstery elements from dismantling to maintain consistency in materials and shades. How well-chosen used seats and benches affect comfort and vehicle value is described in the article: Interior metamorphosis: how branded seats from dismantling improve comfort and increase car value.

Mercedes-Benz M-Class ML W163 Grey Cloth Fabric / Leather Bench Backrest Rear Left N/S Seat is a practical solution for users who want to restore the functionality and consistent look of the rear interior. Its original origin from the Seats and benches group, partial leather finish, and fitment for the rear left side of the vehicle make this element a sensible choice when repairing or refreshing the cabin in Mercedes W163 models.
