  • Edge-to-edge support — prevents that “falling off” feeling on the sides.

  • Long-lasting durability thanks to its robust steel framework.

Miracoil is especially suited to:

  • Back sleepers needing firm, consistent support

  • Couples with different body weights

  • Anyone wanting a budget-friendly mattress without sacrificing structure
