Our control unit has been specially designed to provide you with maximum comfort during the climbing process - whether climbing up or down the stairs. With ease, you can use the control unit to activate or deactivate the stair climber, adjust the speed continuously or decide whether you want to go up or down the stairs.

The control handle also features a safety chip which ensures that the stair climber is only used by authorized persons. Therefore, you can always be sure that your stair climber remains in safe hands, even if you temporarily leave it in the hallway of an apartment building, at the doctor's office or in another public location.

With the Comfort Step, the climbing dynamics of the s-max sella has been revolutionized and offers you an unrivaled comfort experience.

For you as a user, this results in an extremely pleasant and low-vibration climbing process. The Comfort Step is a serial feature of every s-max sella and works in single step mode as well as in the permanent climbing mode.

The stair climber has an integrated LED light on the lower part of the drive unit. This function provides optimum illumination of the steps even in poor lighting conditions. This is particularly important in bigger staircases with an automatic light control system.

One of the most outstanding features of our safety concept is the automatic braking function when descending. This innovative technology prevents the stair climber from being pushed too far over the edge of the stairs. The brakes activate on every step, ensuring optimum safety every time the stair climber is used.
