Will the mattress soften or break in after a few weeks?

Expect a short adjustment, not major softening. The comfort foams relax slightly over the first few weeks as they conform to your body, which is why some owners feel it settle between medium and plush. The 1800-coil support core does not soften; its 13.75-gauge tempered steel holds firm, so the change you feel is the surface foam settling, not the support giving out. Give your body two to three weeks to adapt.
