The X Lounger by Timothy Schreiber which some people call a nest chair.
If you have an affinity for organic yet geometric shapes, this chair should tickle your fancy. The X Lounger is based on a single ray, traced along a periodic double curved surface. Its close resemblance to China’s Bird’s Nest Stadium is a testament to how smart and functional this form is. Strong yet flexible without looking harsh and man made.
