I found this originals chairs, at Cubeme blog, a very good site for discovering the last releases about design. The first one, is a rocking chair by the designer Mathias Koehler. A very circular model that includes a lamp. I really love the nice shape of it.
This next chair, is a concept, but I think is very interesting. At first, this chair it seems to be a hard place to sit, but when you try it, the structure move down with your body weight, adapting it shape to yours. The designer of it, Alessandro Bêda, doesn´t really know if his idea is possible, but in my profesional opinion, yes is it!.
And the last one, the "2F Folding Chair" by Creadesign (designed by Hannu Khnen). A very clever chair, that use the minimum space when it´s close. And when it´s open, it´s so beautifull. Simple and lovely.
