I personally recommend people go to a real furniture store (a large one), where the salesperson is actually knowledgeable and where they offer many brands. Ask for what you want. Specific materials, finishes, price range, etc. Make a note of the brands and manufacturers. Then dig deeper. Often times these brands are featured in a niche catalog or magazine, where you can find similar brands offering similar products.
There are many high quality buy it for life items to be found! But rarely at the convenience of a button click from westelm’s website.
