How long does it take to break in?

Give it a few weeks. A firm 7-out-of-10 bed like this one can feel stiff at first, then ease as the 1.5-inch comfort layer settles and your body adjusts to genuine on-top support. Some owners note it softens slightly after a couple of weeks of nightly use. Sleeping on it consistently speeds the process, and the 365-night trial leaves plenty of runway to be sure the firm feel suits you.
