How long will this tight-top mattress last?

This is the line's most budget-focused build, with a durability score of 6.1 out of 10, fair rather than long-haul. The 416-coil, 13-gauge Bonnell steel core is tough, but the thin 0.75-inch comfort layer softens sooner than a thick euro-top, which is why it fits lighter use like guest and kids rooms best. Rotating it head-to-foot every 3 months helps it wear evenly.
