I like this for some reason. Doesn't look too comfortable and I wouldn't want to have to sit in it for an extended period, but I like the minimalist design using an unconventional structure. And it looks like it could be made without any fasteners, just dowels maybe? A good project for someone with no experience and few tools, maybe just a some kind of saw and a drill. And some clamps to glue the seat.
Along these (unconventional) lines, I have long contemplated building a dining table suspended from the ceiling. Cleaning under the table and chairs is always a pain, involving moving chairs out, then trying to sweep or vacuum around the legs. A design from before we understood gravity and how to defeat it IMO. Just get rid of the legs and hang it from the ceiling! Put these chairs on it while cleaning. And then throw a mattress on it and gently sway yourself to sleep at night whilst dreaming of my mother once singing to me
Rock-a-bye baby, on the treetop,
When the wind blows, the cradle will rock.
When the bough breaks, the cradle will fall,
And down will come baby, cradle and all.
Was never sure if that was meant to soothe or threaten me.
