Are cheap metal platform frames sturdy enough, or do they squeak?

Squeak and wobble are the single most common complaints in community threads. The pattern across reviewers: frames with a reinforced center support leg and properly tightened hardware stay quiet for years, while under-tightened or lightweight builds 'jiggle every time you turn over.' Heavier-gauge steel frames (NEW JETO, VASAGLE-class) and solid-wood designs (Mellow, Zinus Vivek) draw the fewest noise complaints.
