BENTLEY ARNAGE T 2005 Mulliner Leather Seat

For the 2005 Bentley Arnage T, the Mulliner specification represents the pinnacle of hand-crafted luxury. Unlike the modern Continental GTs, the Arnage was one of the last “coach-built” Bentleys, meaning the seats were constructed with a level of density and heavy-gauge leather that is rare in contemporary cars.

1. Mulliner Seat Characteristics

The 2005 Arnage T Mulliner interior is defined by several distinct features:

• Diamond Quilting: The seat centers and door panels feature the iconic “Diamond-in-Diamond” quilted stitching.

• Embroidered Emblems: The Bentley “Winged B” is embroidered directly into the headrests, often in a contrast thread to match the piping.

• Hide Quality: Uses Grade A Connolly-style leather (specifically “Autolux” or “Vaumol” types in older parlance). The leather is noticeably thicker and more fragrant than standard automotive hides.

• Adjustability: 8-way power-adjustable front buckets with 4 memory settings and multi-level heating.

2. Common 2005 Mulliner Packages

In 2005, there were two primary levels of Mulliner seating options:

• Level I: Standard Arnage T sport seats with smooth leather and embroidered logos.

• Level II: The “full” experience, adding Diamond Quilting, electrically adjustable and massaging rear seats, and veneered picnic tables on the front seatbacks.

3. Color & Trim Codes

If you are looking for replacement leather or a donor seat, you must match the Bentley “Hide” color code. Common 2005 colors included:

• Beluga (1NN): Deep Solid Black.

• Magnolia (VM3997): The classic warm cream/white.

• Hotspur: A vibrant “Bentley Red.”

• Cotswold: A neutral, earthy beige.

4. Maintenance & Restoration (2026)

The seats in a 2005 Arnage are now over 20 years old. Common issues include:

• Bolster Wear: The high side-bolsters on the “T” models are prone to “scuffing” from entry and exit.

• Foam Collapse: The internal seat foam (latex-based) can begin to crumble, causing the leather to look “baggy.”

• Heating Element Failure: The carbon-fiber heating pads can break; these are often stitched into the leather covers and require a specialist to replace.
