The EVAC+CHAIR is the original emergency evacuation chair. There are plenty of copycat competitors, but as usual, the original is still the best.
The evacuation chair is simple. It works every time. It is intuitive so anyone can use it, even without training or instruction. There are no complicated add-ons to break. No gimmicky features to snag or fail. It simply works, effectively, easily, and does what it was designed to do: save lives.
