Purpose and function in the vehicle

The presented armrest is a component designed for installation in the rear seat bench, in the second-row passenger area. Its purpose is to provide stable support while driving and to organize the space between the seats. The foldable design allows for quick adjustment of the interior to current needs – in the folded position, it does not restrict space, and when unfolded, it creates a comfortable rest zone for passengers.

Construction and materials

The armrest is made of black leather, which allows for an aesthetic match to typical upholstery configurations in the ML W166 model. The leather surface is pleasant to the touch and easy to keep clean, while the carefully selected material texture ensures visual consistency with the factory finish. The construction has been designed for use in the rear of the vehicle, with an emphasis on hinge durability and stability in the unfolded position.

Usage comfort and ergonomics

The foldable rear seat armrest improves seating ergonomics, especially during longer trips. The appropriate height and width ensure a natural arm position, which reduces passenger fatigue. Thanks to the factory design for the Mercedes ML W166, the element integrates well with the seat, without causing play or unwanted noises while driving, which translates into acoustic and functional comfort.

Why choose an original used part

An original armrest from this series is a beneficial solution both technically and economically. Compared to replacements, it provides:

• factory fitment to the rear seat bench structure,
• color and material consistency with other interior elements,
• preservation of the original folding functionality.

A used OEM element allows you to maintain the interior character typical of the Mercedes brand, while reducing costs compared to new components.
