I really like Barcelona Chairs. I like Eames lounges and Egg chairs better. All three are really at the point where they are "period" designs. The best looking modern furniture that I have seen in a traditional environment have been various Ron Arad one-off pieces. I was at a Palazzo outside of Torino this summer and it was filled with Ron Arad furniture. It looked amazing, but there was nowhere that was comfortable to sit. I've often found egg chairs to be gimmicky, and unless well done, slightly on the Ikea side. Mies van der Rohe managed to avoid the sparcity that underlies most "modern" design. I think he distilled opulence to its simplest form, making it the most timeless of perhaps all the creations we're mentioning here. With a few idiomatic flourishes, I one could easily picture a Barcelona chair in virtually any period of time. Eames chairs are great, but like you say, you sit low, and it seems that every Frasier wannabe yuppie has them. Although, Barcelona chairs seem to occupy every upscale lobby and waiting room in existence.
