It might seem it has a fragile structure but it is mathematically safe. La Smilza can be considered a spacial reticular structure and it responds to the physical principle of levers. It is composed by broomsticks, 3D printed joints and a suspended seat secured with ropes to the frame. The structure reacts to different strengths depending on how the joints are placed. The chair is designed to be unique, personal, built on the owner's needs and anatomic features. It is transportable, its owner can bring it with him wherever he goes and it will adapt to every situation like a Darwinian creature.
