        But consider: a three legged chair won't wobble

        They are also easier to stack/store/ship economically with minimal empty space.

        You can tile a plane with triangles, so that's not a reason.

        Which is why 3 legged chairs are oriented in opposite direction from your diagram https://blog.lostartpress.com/2015/10/22/these-swiss-are-in-grave-danger/ …pic.twitter.com/FfLcZZnxbn

        the pentagonal isn't better if we fix the diameter, rather than the side length?

        Horizontal geometry is part of the proble., vertical geometry and center of mass is the other

        But three points share only a common plane(1 stable position) ,four points two planes(2 stable positions) ... shouldn't this (non extra) point be considered in favour of 3-legged chairs? :)
