Archelis is a wearable chair that can help medical personnel sit and stand without muscle fatigue. While in surgery, medical specialists, especially surgeons, are forced to bend or lean over for long periods. Archelis supports bodyweight by supporting a large area of shin and femur to dissipate pressure. A design of separated legs enables people to take a stance that suits their posture. Since Archelis requires no electric power and can be used without cables, it provides stable movements and safety in a surgical theater.
