Here is a mention of the couch: http://en.wikipedia.org/wiki/Egg_(chair)
Still haven't found pictures though. Maybe it's just a myth.
Quote:
The Egg was (as was the Swan) designed as a couch also - though the actual piece was thought to be a figment of someone's imagination, fed by the existence of the Swan-couch. While the Swan-couch is still in production, only a handful of Egg-couches have ever been made. A few were made for the Radisson Hotel, and a few years back, some were made as a "special edition" couch. The price was quite high - about 400.000 dkr., the equivalent of 60,000 USD.



THE CHAIR: The problem I and many others seems to have with The Egg chair is its seating - it is not as comfortable as you would imagine a chair like this would be. You sit in a straight "conservative" position and the pillow also slides forward. Disturbing as you should relax when seated. The original or first Egg chairs did not have this problem since there was no pillow to slide. The foot on those first chairs also differs from the one of today. If you are going to buy the Egg chair remember two things: Only Fritz Hansen got the right to produce it, so only the ones from Fritz Hansen can be considered originals. Secondly, go for an older Egg, as the patine makes it more beautiful.
