We spent around $4000 for our master bedroom furniture. American (Amish) made, solid wood that we plan to keep forever. My husband has good taste and likes to buy high *quality* items. I'm more frugal but willing to go along if I see it as a forever-purchase.
We had more hesitation about dropping $4000 on a genuine leather couch and ottoman. Again, American-made, and this time, the builder custom-built it to our specifications. We'd been looking for two years and couldn't find anything that fit our needs. We're tall and my husband has really broad shoulders. Standard 21" cushion depth just wasn't cutting it for us, and we had it built extra-long as well for napping on. Napping on a couch might not be important to everyone, but we're thoughtful about how we really live, and we nap on the couch. The main reason we hesitated is because we have an unruly toddler and a second baby on the way... but we've had several friends assure us that leather is good for raising kids. And we were SO TIRED of not having any living room furniture! Every time we looked on Craigslist or hit up a secondhand store all we felt was despair, and every time we hit up a regular furniture store all we felt was disgust at the value and very few options presented.
We've been furnishing our home very slowly because we are so picky. The things that end up satisfying us tend to cost more, and so we can't go on shopping sprees - we have to save for a while. Perhaps not very Mustachian, but the important thing is the focus on VALUE or cost per use, and absolute unanimity between the two of us. My husband isn't particularly interested in FIRE, but we can furnish this way even when he maxes out his tax-advantaged accounts, so it works for us as a couple. When we decide that something is good enough quality, and with classic enough lines that it could perhaps be used by our grandchildren, we know we're ready to pull the trigger on a purchase. Our house does not look like one of those modern home-blogger houses with the pops of color and the white-painted-everything. In fact I really don't see decor like ours on any blogs :)
