About Us

Redefining Comfort and Individualization.

Revolutionizing what’s next in custom seating.

Matrix Seating began in the late 1970s as a Canadian research project developing one of the first dynamic custom seating systems. It evolved across Europe, refining technology that balanced precise support with therapeutic movement.

In the 2000s, entrepreneur and ATP Greg Sims recognized its potential and introduced Matrix to the United States. While clinicians valued its clinical outcomes, long adjustment times and U.S. reimbursement challenges made it difficult to sustain.

In 2020, as COVID-19 reshaped healthcare, Greg, now Founder and CEO of Matrix Seating USA, partnered with engineers at the University of Florida to reinvent the system. By integrating 3D printing, a new generation of seating emerged, engineered for airflow, adjustability, durability, and infection control. This innovation led to the first generation of AIREZ cushions and back supports.

Never one to stop innovating, Greg continued refining every detail. After years of research, testing, and clinical feedback, AIREZ 2.0 launched in August 2025, a revolutionary solution designed to protect skin, support complex postures, and promote independence. But the story of comfort, technology, and custom seating innovation has only just begun.

The Team

A cross-disciplinary team of ATPs, PTs/OTs, designers, and engineers working side-by-side to turn complex needs into simple, durable solutions. At the intersection of clinic and lab, we design, test, and refine the Matrix product line, built for real users, real outcomes, and everyday independence.

The Team.

1975–1978

Development begins on a universal orthotic and prosthetic body support system; the foundation that would eventually evolve into modern custom seating.
