So one step up from that becomes "real wood" and suddenly you need a human spending a ton of time paying attention to the grain, and idiosyncrasies of the wood etc. Labor costs shoot through the roof for even relatively simple furniture
The stores you mentioned, even when the furniture is $3000, is made a step up from IKEA in that it’s not pressboard, but it’s probably veneered or made to look “distressed” and dyed as a way to hide the wood it’s made from. You’ll see screws instead of mortise and tenon joints, you’ll see comically obvious grain mismatches, the stuff is just sloppy.
Find a local woodworker, pick timeless styles and get it made from a wood that isn’t that expensive but is beautiful and easy to work like cherry. It will cost something similar to what crate and barrel charges, and you’ll have it in 50 years.
