SOMA 105 Ultralight Aluminum Wheelchair

Seamless Elliptical Frame

SOMA 105 is designed to challenge the conventional image of wheelchairs. The end result is not only stylish but also durable.

The seamless elliptical frame achieves this goal by reducing the welding points and rectangular shape of the chair. We want to change the look of the wheelchair while at the same time keep it reliable and affordable.
