Most road cars are improved for drag reduction while downforce has priority in racing. The rear wings of F1 cars add to that downforce. The chair you see has 4 inverted wings to produce downforce.
Vortices are very important flow structures. They can be extremely powerful, like in a tornado, but this power can be leveraged using aerodynamic analysis. This can be observed in Formula 1 cars and how they use purposefully generated vortices to increase the effectiveness of the rear wing and push the tyre wake away from the body. Look up the famous Y-250 vortex.
As an aerodynamicist, I wanted to design a chair that would show the unseen power of air and have its surfaces selected using aerodynamic analysis, to produce strong vortices. I started with a baseline design which evolved into many different shapes, using Computational Fluid Dynamics software and iterating the design until I found the one that generates the most powerful and distinct vortices.
