As for other pieces of furniture, e.g., cabinets and stuff, we bought them used from a place that combed estate sales in Denmark for furniture and sold it in the US. One attraction is that the old furniture is smaller, so it works in a smaller house.
Same goes for old wooden windows etc. that can last a hundred years or more if properly taken care of.

The key may be the "properly taken care of" part (or they didn't buy crap at the time part).
I live in a greater than 200 year old house and all the older windows dating to whenever are complete crap compared to newer Andersens I've had installed.

I wrote my original post in haste - the cost was for doing the couch and a matching chair (same side-profile, just narrower.)
I wonder, is it even possible it's solidly made despite being very light?
I sourced high-quality foam and wool upholstery fabric from Maharam and took those to one of the best upholsterers/furniture restorers in Los Angeles. They did a wonderful job and now I have a super-comfortable couch with many good childhood memories, that should last me another 25 years before I need to replace the cushions again.
Point being, get a classic old piece and restore it. It will last a lifetime.
