I’m certainly not an expert, but I do have a bachelors in furniture design. I was just saying midcentury modern is hard to define. I have his book Soul of a Tree. An excellent read for any woodworker or furniture design. I highly recommend it. I also have several references that clearly state he is mid century modern. Including the link I posted at knoll. He has three pieces that are still “ mass manufactured” at Knoll. Look at his Japanese-inspired more Modernist designs such as the Conoid range. That style fits perfectly with mid century modern tastes in interior design.
