Application and compatibility

The offered seat backrest is designed for installation in the front of the vehicle and can be used on both the left and right sides. By maintaining factory geometry and mounting points, this component is suitable for BMW X3 E83 LCI vehicles equipped with heated sports seats.

This solution is particularly effective for replacing a damaged backrest following a collision, wear and tear, or during partial interior restoration, where maintaining the manufacturer's original specifications is a priority.

Construction, material, and features

The backrest is built in a sports configuration, which means more pronounced side bolsters and better torso support while driving. The Oyster Leather upholstery provides a bright, elegant finish that blends well with factory BMW X3 E83 LCI interior arrangements.

The backrest features an integrated heating system, allowing it to work with the factory seat heating circuit. This ensures thermal comfort in colder conditions and full equipment functionality without the need for electrical system modifications in the vehicle.

Benefits of installing an OEM used backrest

Choosing an original seat backrest from a dismantled vehicle allows you to maintain the visual and technical consistency of the interior while reducing costs compared to new parts. The factory upholstery line, correct foam shape, and compatibility with standard rails and adjustment mechanisms are preserved.

Key advantages include:

• maintaining the original character of the BMW X3 E83 LCI interior,
• sports back support improving body stabilization,
• integration with the factory seat heating system,
• versatility for use on either the driver or passenger side at the front of the vehicle.

Installation area and practical aspects

The backrest is intended for installation in the front cabin, replacing the standard sports seat backrest. The design, suitable for both the left and right sides, facilitates the selection of the appropriate component for post-accident repairs or when replacing a single seat.

During installation, it is recommended to follow BMW service procedures, particularly regarding the electrical system responsible for heating and any passenger presence sensors, if present in the specific vehicle configuration.
