Is this a Flemming Lassen take two?  

@taketwo2025 Your first attempt wasn't banned, thanks for the ID question.

Welcome to DA Forum! 

The examples you've provided links for are remarkably similar indeed. And your photos reveal high-quality construction consistent with better makers at the time. (sometimes the old ways are still the best!) And, sometimes, close enough is close enough. Without a definitive attribution, however, I prefer "style of" over "attributed to". "Attributed by whom, exactly?" is the question that pops into my head whenever I read or hear the latter.

Nice neat workspace, btw. Not at all like mine lately.

Hi, I took another look at the sofa. It doesn't look Danish. That doesn't mean it isn't Danish—but it doesn't look Danish. You found four dealers who sold it, at least two of whom are based in Germany. You also found German money in your sofa. I know that West Germany was a major export market for Scandinavian furniture in the 1950s and '60s—but by no means the biggest.

If at least three out of five models were sold in or located in Germany, I think it's quite likely that it's actually a German production. It doesn’t have to be, but I think it's probable. Sweden is also a possibility, but in that case I’d expect to see it more on the Swedish market.

I consider Flemming Lassen as the designer to be out of the question. Lassen's furniture was made in tiny quantities by Copenhagen’s top cabinetmakers. As far as I know, he never designed for an industrial manufacturer. When his pieces come up on the market, it’s in Denmark—and at outrageous prices—not in Germany or the UK.

"Attributed to" usually just means: I have no idea, but I’ve seen something kind of similar by...
