Are cheap Amazon dining chairs durable enough for daily use?

It depends on construction. Across r/HomeDecorating and r/bitcheswithtaste, the recurring advice is that flat-pack chairs which fully disassemble tend to loosen over time, and that metal-base or 'contract grade' frames hold up better than wood four-leg bases. Several sets here are reported as sturdy by verified-purchase reviewers, but buyers consistently recommend checking weight ratings (many list 300 lbs) and tightening hardware periodically.
