West Elm's quality has definitely dropped the last 10 years. It's still not a bad place to get things like side tables, but I definitely wouldn't buy any furniture there any more, which is too bad. We had gotten a couple of nice pieces there in the past, although they're now gone.
For quality modern furniture, the only game in town around me is Room & Board. The last couch we bought there was ~$6k[0]. It's a lot, but we'd honestly been eyeing it for almost 20 years and it'll likely be something we have for another 20 years or more.
