Back pain from long sitting at computer, plus aging discs, sent me looking for an affordable desk chair. No amount of internet research can provide complete confidence, so I ordered the Nouhaus Ergo3D with some trepidation. Punch line: it immediately felt great to sit in, and remains comfy after a few days with hours of sitting. Assembly wasn't bad. Parts quality seems fine for in-home use. Easy to lean back all the way and drift into sleep.
