We bought two Kennewick lounge chairs. Keeping in mind that real mid century-style seating was generally firm by today's standards - the Kennewicks are also very firm. Also, the frame is not sufficiently wrapped at the edges/corners, so you can feel the hard frame edges in some places. The upside is that there is plenty of support and the firm padding isn't going to sag or deform over the years.

I didn't buy couches or chairs (got those from CB2 and West Elm). I did buy the Mango TV stand, Atomic Island Cabinet, a cool modern desk, two bookstands, 4 little side tables, a wall clock, and some pillow cases - all of which I love and worked out great for the spots I placed them in.
