Some one else mentioned Maiden Home. Their furniture seems to be well made based on research. They also have a couple sofas that might fit the style you are looking for if you are considering the RH Cloud sofa. I recommend checking out the Dune or Jones sofas from Maiden Home. More on reddit.com

Did you find anything using the search function? This question is asked a lot. Furthermore, there are no details. What size is the sectional? What shape? Does it have a chaise? What's your budget? Higher quality USA-made sectionals start at $10,000. High end European sectionals start at $20,000. For background on sofa and sectional build quality, see this comment. Link: https://www.reddit.com/r/BuyItForLife/comments/1bglyfz/comment/kv85zpv/ Higher quality USA brands are Taylor King, Hancock and Moore, Sherrill Furniture, Century, Vanguard, and Stickley. High end European would be Minotti, Poltrona Frau, Cassina, Baxter, B&B Italia, Cappellini, de Sede, etc. These brands are designer pieces and meant to be heirlooms, hence the huge price tag. A somewhat cheaper German brand to the (mostly) Italian offerings above is Himolla, which makes modern modular sectionals you can configure. Upholstery & COM As for machine washable upholstery, you will need to ask on a case-by-case basis. To start, fabrics should have a "W" cleaning code. However, that does not mean you can throw it in the washing machine. If you can't find anything in the brand's fabric library, consider COM. COM or Customer's Own Material means you acquire your own material for a furniture brand or maker to use. If you go this route and want high durability, consider looking for upholstery adhering to Association for Contract Textiles (ACT) guidelines. Most fabric libraries—even for premium furniture brands—have not been tested to and may not meet these more stringent ACT standards. In particular, the Physical Properties test methods such as Seam Slippage, Breaking Strength, and Pilling represent forces operating on fabric that the Wyzenbeek (double rub) or Martindale test methods do not. Despite what some think, a rub count value is not the ultimate nor the only criterion for a hard-wearing fabric! Since many brands do not offer ACT certified fabrics to residential customers, you would need to order them as COM. The issue here is that for some brands, COM makes a piece super-customized and therefore ineligible for returns or refunds. Some makers simply do not warrant COM. You will need to check. Last caveat: because of high strength synthetic fibers, some ACT materials feel scratchy, rough, or unpleasant against skin. You may need to compromise somewhat if "hand" is important. Here's a few wholesalers with ACT fabrics: Architex, Brentano, KB Contract Textiles, Knoll Textiles, Luum Textiles, Mayer Fabrics, Wolf-Gordon More on reddit.com
