Purpose and fitment for Mercedes W639

The presented three-seater bench represents the left part of the rear seat row, designed specifically for the Mercedes W639 model. The construction is compatible with the factory mounting geometry, which facilitates installation in the vehicle and allows for maintaining the original spatial layout of the passenger cabin. Thanks to this, the component works well both for replacing a damaged bench and for completing a full set of seats after interior modifications.

Luxury leather upholstery – comfort and aesthetics

The bench is finished with leather upholstery, which enhances the utility and visual appeal of the interior. The Luxury specification leather trim provides:

• a pleasant-to-the-touch surface with increased resistance to daily use,
• easier maintenance compared to textile materials,
• a consistent, elegant cabin look characteristic of higher-end Mercedes equipment versions.

Thanks to this configuration, the rear part of the interior gains a more representative character, which is important both in private vehicles and those used for business purposes.

Technical and functional characteristics

The three-seater rear bench in the left version has been designed as an element of the Seats and benches category, with an emphasis on ergonomics and stable passenger support. The placement in the rear of the vehicle on the left side allows for the proper use of cargo and passenger space in accordance with the factory design of the Mercedes W639 interior. The seat and backrest construction is adapted for longer journeys, providing adequate back and thigh support, which translates into higher ride comfort.

Condition, origin, and practical application

The item comes from dismantling and is offered as used, which is a cost-effective solution for those looking for original components at a reasonable price. Choosing an original bench from the secondary market allows you to maintain factory build quality and fitment with other interior elements, without the need to use replacements with uncertain specifications. This type of solution is particularly useful for accident repairs, interior restoration, or reconfiguring seat setups in a Mercedes W639.
