What's the cheapest platform bed frame that doesn't squeak?

The Amazon Basics foldable metal frame and the NEW JETO both sit under $100 and have tens of thousands of verified-purchase reviews averaging 4.6–4.7 stars, with squeak complaints in the minority. Reviewers in r/Frugal and r/Mattress note that proper assembly (tightening every bolt, using the included felt pads) is the single biggest factor in noise.
