The first chair I was working with is the voronoi chair. I made the initial curve in Rhino and lofted it over. i then used the gumball tool to change the curves to match the chair. I tried applying the voronoi pattern onto the chair, but it would be applied onto a flat plane and would not go with the organic shape of the chair. I kept playing with different algorithms on Grasshopper but I essentially ended up with the spawns of spiderman (failed).
Below are the images of some of the results I got in my attempts.
