      What the Sleep Expert thinks...

      "Our double-sided Miracoil gives you firm, even support without the weight of a bulky mattress. The head‑to‑toe spring rows stop roll‑together, reinforced edges add space to starfish, and Eco Comfort fibres keep things cool—just flip seasonally and you’re set."
