“Introduction of Simpson Off Road Seats from Leo Grillas”

Hi, I am Leo Grillas, founder of Twisted Stitch, Inc. and now General Manager, Off Road Seats at Simpson Performance Products. In 2007, I founded Twisted Stitch Seats in order to provide the highest quality and most progressively styled seats available to the off road industry. We revolutionized the market by bringing a commitment to design and quality not seen before in our industry, and innovations in frame technology that continue to be the best available. In October of 2014, Twisted Stitch joined the Simpson Performance Products family and continues to provide high-quality, custom off road seats backed by one of the largest motorsport safety companies in the world. With the manpower and technology available in our 55,000 square foot Simpson West Coast Operations facility, located in Harbor City, California, we have been able to take our seats to an all new level. Thank you for your continued support and please stay tuned for more great things to come from Simpson Off Road Seats.
