Porsche Seat Parts | Comfort, Support & Precision Engineering for Every Drive
Seats are among the most important components in your Porsche’s interior — balancing comfort, safety, and driving control. Over time, mechanical seat components such as runners, motors, adjusters, or mounting brackets can wear down, affecting comfort and performance. Proper maintenance and replacement of seat parts ensure your Porsche retains its driving precision and luxury appeal.
At Design911, we supply high-quality seat parts and accessories engineered to meet or exceed original performance standards. Our range includes seat adjustment mechanisms, runners, seat cushions, backrest components, and mounting hardware — all designed for precision fitment and long-lasting reliability.
Whether you’re restoring a classic Porsche 911, upgrading a Cayman, or repairing a Boxster, Design911 offers the seat parts you need to restore comfort, safety, and interior refinement.
What Do Seat Parts Do?
Seat components work together to provide proper ergonomics, support, and functionality inside your Porsche.
Core Functions:

Every Porsche seat is engineered for precision; maintaining its components ensures consistent comfort and safe performance.
