There was a huge display featuring Antonio Citterio's Suita Sofa, which was released in 2010 and which we nominated as a finalist in our 2011 Modern World Awards. The Suita collection is almost endlessly customizable, with components to choose from that include: one-armed seats, two-armed seats, chaise shape, desk along the back, headrests, bolsters, and ottomans. I found the tall sofas with the headrests by far the most comfortable.  Inside the VitraHaus by Miyoko Ohtake
