I recently came upon this picture on the internet..
a Tree Chair. This is definitely for those who want to take going green to a new level. The tree serves as shade, ornamental seating. I personally think it's brilliant. If you want more info. check out Pooktre.
For those who want that organic style in the house but with a twist check these out
I know the chair looks to be uncomfortable but I would put a small sheepskin rug on it.
You can use these chairs in whatever your style is.
What do you think of tree chairs?
