Let us first try to list and sort the most common modern furniture pieces. I believe: Aeron chair Barcelona chair Eames lounge chair and ottoman Le Corbusier LC2 sofa Saarinen tulip chair and table Wassily chair The first three are the most ubiquitous by far. The rest are more disputable and harder to rank. My problem with these pieces is that they are so ubiquitous that I would never buy them. Except for perhaps the Aeron, as it is a functional piece and is ergonomically designed for sitting for long periods—though now there competing designs from other companies. In a vacuum, I don't think any of these designs are particularly amazing, though certainly none are bad. I can only imagine that their popularity is due to bandwagoning. Whenever I see these pieces, usually at an office lobby and sometimes in people's homes I feel that the interior designer lacks imagination. I personally don't buy modern furniture, but if I did I would only buy lesser known pieces.
