Purpose and fitment

The backrest is designed as a rear left seat component, allowing for the precise restoration of the original seat configuration in the Mercedes W164. The construction is based on factory mounting points, which facilitates installation and reduces the need for upholstery or frame modifications.

The element is part of the seating system responsible for providing stable back support for passengers, proper seat belt routing, and maintaining the correct interior geometry. This fitment ensures seamless integration with the remaining seat segments and side upholstery.

Materials and finish

The backrest is finished in a combination of leather and microfibre in an Alpaca Gray tone, providing the understated, elegant look characteristic of Mercedes interiors. The leather provides a pleasant-to-the-touch, durable working surface, while the microfibre improves grip and reduces clothing slippage during travel.

This combination of materials promotes thermal comfort while facilitating daily use and cleaning. The gray color allows for harmonious integration of the backrest into most interior configurations, without a visual "cut-off" effect from the remaining upholstery elements.

Function in the seating system

The rear left backrest plays an important role in the seat structure, responsible for:

• stable back support for the passenger on the left side of the rear bench,
• maintaining a proper seating position during travel,
• visual and functional consistency of the entire row of seats,
• proper load distribution on the seat frame.

By maintaining factory geometry, the backrest supports a comfortable seating position, which is particularly important on longer journeys where seat ergonomics influence passenger fatigue.

Characteristics of the used component

The offered component comes from the secondary market, allowing for economical repair or interior refreshment without the need to invest in a new set of seats. The used element retains its original construction and material, making it a beneficial choice when replacing a damaged or excessively worn backrest.

Choosing an original dismantled backrest also helps maintain consistency with other interior elements, which is important for preserving the vehicle's value and aesthetics.

Interior tuning integration

If you are planning a gradual improvement of the cabin's appearance, replacing individual seat components can be a reasonable step in a broader customization project. The rear left backrest in leather and microfibre fits well into the concept of functional tuning, where both appearance and comfort matter.

Selection and kit expansion

When replacing a single backrest, many users decide to successively match the remaining seat elements so that the entire bench row looks consistent. It is worth paying attention to the compatibility of material, color, and the configuration of backrests and seat cushions to avoid differences in texture or shade.

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