Purpose and compatibility for Ford Focus ST-3 MK3

The presented rear seat base cushioning is designed specifically for the third-generation Ford Focus ST-3 sports version, intended for installation in the rear left side of the cabin. Thanks to its factory-engineered geometry, it maintains proper passenger support and compatibility with the stock seat frame and mounting points in this model. The precise profiling facilitates integration with the remaining rear seat components, which is essential when replacing a single segment instead of the entire set.

Material and finish: Windsor leather in black

The cushion is finished with high-class Windsor leather in black, characteristic of versions with a more dynamic, sporty character. This type of upholstery provides:

• a consistent look with other ST-3 interior elements,
• easier maintenance compared to textile materials,
• adequate resistance to daily use. The black color scheme helps to discreetly mask minor signs of wear and blends well with both light and dark cabin trim elements.

Installation characteristics and service application

The rear seat base cushion on the left side is intended for installation in the rear of the vehicle, replacing the factory seat base. The construction, based on the original Ford design, allows for its use in both post-accident repairs and when replacing a worn upholstery element. In practice, this means the ability to:

• locally replace a damaged segment without interfering with the entire seat,
• restore the functionality and aesthetics of the rear interior,
• maintain compatibility with the factory mounting system and seat shape. This type of component is particularly useful in situations where only one part of the rear seat has been damaged, and the owner wishes to limit the scope of work and costs to the absolute minimum.

Benefits of using an original rear seat base cushion

Using an original rear seat base cushion in a Ford Focus ST-3 MK3 allows for maintaining the stylistic and technical consistency of the interior. Factory fitment translates into proper upholstery alignment, no material tension, and correct support for passengers. For users concerned about the condition of their cabin, it is also important that replacing a single element in the Seats and benches category enables gradual interior renovation without the need for a one-time replacement of the entire seat set. If you are planning a comprehensive repair or upgrade of the seating area in your Ford and need other elements from the same group, such as backrests, center segments, or additional seat modules, check the available parts in the Ford Seats and benches category.

How to build a premium interior with used parts

When selecting used upholstery elements, such as a Windsor leather rear seat base cushion, it is worth paying attention to the consistency of the material, color, and trim version. Properly combining seats, benches, and other components allows for achieving an effect similar to a factory premium package while keeping costs reasonable. Practical tips on assembling seats, steering wheels, and multimedia systems from the secondary market can be found in the article Premium interior for half the price: second-hand seats, steering wheels, and multimedia, which discusses issues of compatibility, selection, and installation of such elements.
