The Biski or Dualski is an adaptive ski chair designed to enable individuals with mobility limitations to participate safely in alpine skiing. It consists of a seat mounted on two parallel skis and can be used independently by an experienced skier or with an assistant depending on the user’s skill level and the model.
The seat is ergonomic, providing trunk and pelvic support. Retention systems and adjustable straps ensure safety during downhill skiing. Some models include a handlebar for directional control or manual brakes to regulate speed.
