Porsche 918 fixed carbon bucket seats

If your car is equipped with the 918 fixed carbon bucket seats, changing the appearance has never been easier.

Choose from the OEM 911R onwards factory Black/Silver or Agate Grey material (not a reproduction) or our range of Pepita Houndstooth Fabric.

This set comes complete with new backrest and seat base foams (softer than the factory originals) covered in your desired material and fitting is straightforward.

Some found the factory original foams too hard so we have developed replacement foam sets slightly softer than the factory originals for a more comfortable ride, but still with all the factory details.

Please Note
When fitting sets to 2021 seats and onward make sure you disconnect the battery while working on the seats in order not to get any warning lights appearing.

Side bolster protector covers. Porsche 918 fixed bucket seats

retrotrim

If your car is equipped with the 918 fixed carbon bucket seats, it can be a physical challenge climbing in and out, leading to visible scuffing, deep creases in the leather trim and torn stitching.

Here is a solution in the form of its 918 seat bolster protectors.

Once installed over the outside bolsters of both seats, this new-to-market product perfectly replicates the look of the standard bolster due to being made from Porsche factory black Napa leather and deviated stitching in the colour of your choice.
Along with the additional 'cuff cover', these protectors will also shield the rear of the bolster without looking out of place and installation is easy.
Please Note Protector "Cuff" does not have deviated stitching

Sold as a pair - Left and Right seat

About Seat Restoration

Porsche Seat Restoration Parts | Design911 Components for Classic Seat Rebuilds & Interior Renewal

Seat restoration parts are vital for bringing your Porsche’s interior back to its original comfort, style, and functionality. Over time, seat components such as foams, frames, covers, and adjustment mechanisms can deteriorate — reducing both appearance and comfort. Using precision-engineered restoration parts ensures your Porsche’s seats regain their structural integrity, support, and period-correct finish, whether you’re carrying out a full rebuild or targeted repair.

At Design911, we supply an extensive range of seat restoration components, including cushions, backrests, seat foams, covers, hinges, and mounting hardware. Each part is crafted to match Porsche design standards for accuracy and fitment while using durable, modern materials for enhanced longevity. Perfect for classic restorations, refurbishments, and interior upgrades, our seat restoration parts allow enthusiasts and professionals to preserve both comfort and originality.

What Do Seat Restoration Parts Do?

Seat restoration parts restore the shape, support, and function of worn or damaged seats, ensuring long-term comfort and authentic Porsche quality.

Core Functions:
• Rebuild the seat structure, restoring comfort and support.
• Replace worn-out foams, springs, or covers.
• Repair mechanical adjustment functions for proper alignment.
• Maintain authentic appearance and period-correct design.
• Improve driving ergonomics and interior presentation.

A properly restored seat enhances both the visual appeal and driving experience, maintaining the timeless character of your Porsche.

Why Do Seats Degrade or Fail?

Seat components are exposed to constant use, temperature fluctuations, and sunlight — all of which cause deterioration over time.

Common Causes of Failure Include:
• Foam breakdown leading to sagging and discomfort.
• Cracked leather, vinyl, or stitching from UV exposure.
• Rust or fatigue in seat frames and hinges.
• Worn or seized adjustment mechanisms.
• Missing trim pieces or hardware affecting seat alignment.

When seats lose structure or comfort, it impacts both driving ergonomics and the interior’s overall quality — making restoration essential for comfort and value.
