Do firm mattresses last longer, and how durable is this one?

Firmer beds often show body impressions more slowly because the surface flexes less, and this euro-top scores 7.5 out of 10 for durability. The 416-coil, 12.5-gauge double-tempered steel core resists sagging for years, and the firm HD comfort foam holds its shape better than a plush layer would. Rotate it head-to-foot every 3 months and keep it on a firm foundation to extend that life.
