The stair climber for your wheelchair

In everyday situations stairs pose a problem for many people. Be it in school, at work or on your way to friends or sports activities – stairs are everywhere. The s-max helps you to overcome this barrier safely.

Mobility is quality of life —

overcome daily obstacles comfortably in your own wheelchair

To keep up with the times we developed the s-max, i.e. innovative technology born of original and creative ideas. The s-max’s thought-out safety concept includes brakes that stop automatically at the edge of each step. The intelligent technology is responsible for the particularly safe and effortless climbing process. An engine immobiliser prevents unauthorized use thus adding extra safety.
The climbing speed is individually adjustable to adapt to various climbing situations. If desired the single step mode can be turned off. The s-max is quickly and easily mounted and, due to its compact measurements, it is also suitable for particularly narrow wheelchairs – minimum seat width is 24 cm.

Climbing stairs in the dark is made easy by the integrated LEDs.
