Awesome design. This comment from the OddlySatisfying subreddit thread: "This table and chair set is either an original or a reproduction of a Hans Olsen for Frem Rojile dining set. In Olsen's first iteration of the dining set, the chairs had three legs... the three-legged chairs proved to be too wobbly, so later versions of the set were manufactured with four legs rather than three."
If you are interested, it will set you back a pretty penny.
