Is called Yin Yang and it looks exactly like the symbol of yin yang: "This Symbol represents the ancient Chinese understanding of how things work. The outer circle represents "everything", while the black and white shapes within the circle represent the interaction of two energies, called "yin" (black) and "yang" (white), which cause everything to happen. They are not completely black or white, just as things in life are not completely black or white, and they cannot exist without each other."( http://fly.cc.fer.hr/~shlede/ying/yang.html).
It is a mixture of ancient culture and modern furniture design.. I have seen this chair on a shop and I try it.. It is very comfortable! It is a very beautiful construction made very carefully so when you sit you relax .. I wish I had it at my house! Imagine to sit on a beach and enjoy the sea .. like the picture above .. in word of speach abssolutelly"magic"! While you sitting you can have a discussion with your friend sitting next to you, you can read a nice book, or can simply relax.. Both seats come together very carefully and create a full circle, above there are pillows, which offers you rest..It has an advantage you can placed it everywhere..in a home, in a garden, in a countryside even on a beach!!
