If you're a grass-is-always-greener type, you might have trouble settling on one type of chair: Arm or rocking. This Fotel chair is actually both, and manages to look pretty slick at the same time.
It looks like you can just rotate the non-seat part of the chair (carbon-fiber armrests and legs) while keeping the seat steady to transform it from a rocking chair to a standard armchair, which is such a simple idea we can't believe we haven't seen it before. The seat itself is made of stretchy elastic like in some office chairs and we can assume the whole chair is very light—but not inexpensive. We're not sure if the chair actually exists to be bought anywhere, but an idea this simple probably won't stay conceptual for long. [Yanko Design via Boing Boing Gadgets]
