I'd highly recommend finding a local shop for furniture, if you can. You're right that the major brands cost a
lot of money for quality, so even if a local place seems pricier than an "economy" couch at Ikea or West Elm, you're getting a much better piece of furniture.
Unaffiliated plug, but there is a sofa shop in the Castro in SF (I think they also have a location in the East Bay) where we bought our new couch a couple years ago. The brothers who own the business were very patient about explaining the different kinds of cushion materials and how we could expect them to wear, let us take home several books of fabric swatches to compare within our own home (for days!), and told us if we didn't like the feet once it got to our place they would switch them out for free. Needless to say, that buying experience is completely different from a corporate store.
It only wound up costing 10-20% more than the similar couches we were evaluating at retail shops and has been so much more comfortable and so much more durable than the furniture we ever bought from those places. They've got an outstanding warranty, so we know if we ever did experience unexpected wear and tear they would replace it immediately, and that if 5 or 10 years from now we want to refresh the cushion they can help us with that too.
Just like that small software startup is beating the big guys at the same game...You may have a local furniture shop within your local area that can offer you a much better quality to price ratio and bring your money right back into the local economy instead of sending it to a distant conglomerate.
