Don't know if it is really possible.  After all, sitting in a metal tube at 35k feet and eating food that's been cooked 2 weeks ago is not natural.  Sitting in a chair, any chair for over 2 hours is not natural either.  But alas, designers are looking out for your lumbar, more here via Wired.

Some refer to it as economy class syndrome. To others it's know as a coach class clot. But whatever you call it, sitting squeezed into an airplane seat until you develop deep vein thrombosis is no way to die. And that's why this strange new seat is worth checking out.

The Cozy Suite (sort of a cheesy name, we know) is a staggered seat configuration designed to give passengers a better shot at getting some shut-eye during their flight. Delta just put in a big order for the seats, and surprisingly, plans to install them in the often overlooked coach class cabin.
