The “best” chair that I’ve designed is the Cataract Ergonomic Rocker. I consider it my “best” chair because it is the most original concept (my “favorite” chair is actually the Cascade Rocker). I had a client who wanted a desk chair that was strong enough for him to rock back on. He simply loved to lean back in chairs, but they kept breaking (your mum was right, don’t rock back on the chairs!).
