Do metal bed frames squeak?

Our frames are welded, so their joints do not work loose like flat-pack furniture and the bed stays quiet. The mattress bases have timber slats in flexible holders and pads under the feet that soften contact with the floor. Tighten the assembly bolts once more after a few weeks of use, and on an uneven floor put a pad under a foot so the bed stands firmly on every support. Follow the squeak diagnosis guide.
