That’s not quite true, because many people don’t have good custom sofa makers near them. Moreover, because they are small businesses, they don’t have the same capacity for marketing as big brands; most of their business is word of mouth.

Also, custom sofas take time to build - not much, but 2-4 weeks or so.

So there are a lot of reasons big brands are convenient. But you pay for that convenience in quality.

Not sure about sofas but when I bought a bed and some bookcases and nightstands last year all from national retailers, the lead time was 4-12 weeks depending on the product. Getting a custom sofa in 2-4 weeks would beat the competition in many cases. Again, the market constraint lies in knowing about the small vendor in the first place and having a way to purchase it conveniently.
