Purpose and fitment for Mercedes W166

The presented item is a rear seat backrest cover mounted on the left side in W166 series models. As a part from the Seats and Benches group, it has been designed for a specific body type, which translates into the correct shape, proper contours, and mounting holes consistent with the factory backrest structure. Such fitment reduces the need for modifications and facilitates installation for an upholsterer or a mechanic specializing in interiors.

Construction: fabric and imitation leather

The cover combines two types of materials – fabric and imitation leather. The fabric provides a pleasant-to-touch, thermally neutral contact with clothing, which is important both in summer and winter. In turn, the leather-like material sections improve resistance to abrasion in critical areas and make the surface easier to keep clean, as dirt can be removed with standard upholstery care products.

This combination of materials is characteristic of many Mercedes W166 interior configurations and allows for maintaining visual consistency with other seat elements, without the need to replace the entire bench.

Function in the rear seat – left side

The element is intended for installation in the rear of the vehicle, on the left side. It is responsible for:

• covering the backrest foam and protecting it against mechanical damage,
• maintaining the proper shape of the backrest thanks to factory stitching and panels,
• preserving seat ergonomics for the passenger on the left side in the rear.

Thanks to the dedicated placement on the vehicle, installation does not require fitting universal covers, which reduces the risk of material wrinkling and improves mounting stability on the backrest structure.

Characteristics of the used part

The cover comes from dismantling, which means it is a used part. For many Mercedes users, this is a reasonable compromise between cost and maintaining the original interior specification – you receive a factory component with the correct cut and stitch line, without the need to invest in complete, new upholstery. A used part also allows for easier visual matching to other interior parts, which also have their own mileage and natural signs of wear.

Application in interior tuning and renovation

The Mercedes W166 Rear Seat Backrest Left N/S Back Cover Fabric Imitation Leather can be used both in classic repair of damaged upholstery and in a subtle interior tuning project focused on improving the comfort of rear passengers. Replacing the cover itself is often sufficient to restore the aesthetics of the rear bench after abrasions, tears, or local damage, without interfering with the seat structure.
