This is turning out as an interesting design. I am personally not that modernist leaning in my tastes, but I like to play with combining shapes and doing technical things for the heck of it. It occurred to me I could use the bent u-shape I used on other chairs to do this one, since it does actually work for parking one’s posterior and I know how to make it already. I was gonna do something trapezoidal, but really this is easier to make for me and introduces a whole new level to the geometric presentation of the chair from every angle. Chairs are sculpture in the round, which is part of why, aesthetically speaking, making a good one is considered so challenging. In reality they aren’t that hard to do, but one does have to know enough to do joinery well.
