Elios
Elios is a high density stacking chair and is light both physically and visually, it can achieve a stack of 40 unupholstered chairs on its trolley, fitting through a standard doorway.
However, it is the little things it does that make the difference, the way the seat and back mouldings encapsulate the frame, the way the arm cantilevers from the back and the detachable writing tablet to name a few.
