Fascinating perspective! I don't think anything in my house cost over $500, including beds, couch, TV and appliances. What item can you get for $14k?

Personally I'd rather buy one from IKEA and use the change left over from $12k to buy.. a used truck to drive the sofa home in.. but apparently there's a market.
You can certainly go much higher for smaller companies producing actual custom stuff, using exotic materials, for a giant sectional instead of a single sofa, etc.
But even brands like Herman Miller or Ekornes can really add up. (And I don't think of them as being the highest-end of things. Even hiring a quality woodworker to make something for you can end up similarly priced depending on detailing, finish, wood species, etc.)
Doesn’t need to be $14k, but probably $4k bare minimum, without paying a premium for a brand name or anything like that, nor going with leather.
The cheaper ones almost always use low-density foam that compresses badly with use in a couple years (IKEA is a big exception here! But also most of their sofas are more than $500…), frames that start to get iffy in a few years, and upholstery that looks ratty after a similar amount of time.
