The scene sucks… The chair is amazing! 
I think the room does what it’s supposed to.
Hehe… Not as I hoped, but if you like it 
I think the model is good, but… not loyal to the real object.
The back straps (vertical) are 8, while the bottom ones (horizontal) are 9.
The stool is smaller.
It only has 3*3 “buttons” and the straps are only 7.
Other than this, it’s a good model.
I’m also making my version of it and a scene.
I’ll show it here in a few days.
I wanted to delete this post.
OK, since I can’t, I’ll update this one with the rendering of my Barcelona Cair, when ready.
