Custom Wheelchair by Matsunaga: A New Era in the UK & Europe

The Matsunaga brand (SEED: seed) is making its debut in the UK and Europe, bringing with it a legacy of innovation and a loyal following. Just like a seed that grows with water and care, our vision is to cultivate a thriving community—nurturing growth, blooming with opportunity, and continuously planting new “seeds” for the future.

Join us in creating this positive cycle, where passion meets performance, and together, we redefine the landscape of mobility.

The “Bi” Frame – Strength Meets Beauty

Matsunaga has revolutionized wheelchair design with the “Bi” FRAME (美), where “美” means beauty. By constructing both sides of the frame—from the footrest area to the top—without welding, the result is a lighter, more durable structure that enhances both aesthetics and performance.

The frame incorporates Matsunaga’s original Minamo pipe, a specially designed material that is both rigid and lightweight. This advanced technology is strategically applied to key driving components, improving strength, stability, and comfort—ensuring a smoother, more responsive ride.
