ID thoughts on scissor chair  

That's different.  I'd have extended that rear leg somewhat, for appearance and for stability ?  Still,  a fresh take on the type . . .

I'll have to return to this with another picture, but in the meantime, a note: 
The sling seems to have been adapted at a later date. There are straps on the back as if to support a cushion. I'll add a picture later. 
Also, I agree about the leg. It seems like a strange design decision. Also, the construction seems odd to me. The way the two legs intersect seems awkward.

Yes -- one wonders at first if it isn't sideways or upside down !  But it is an interesting design.  The cross lap at center is potentially a very strong connection;  if the bents have good splines or tenons, the piece should be quite sturdy -- and adventuresome at the same time. One could call it the Double Boomerang Chair . . .
Sometimes we see a design and want to take it as a starting point.  I always strive for some kind of arm, so it would be fun to see if that could happen too.
