  • Soft, a 3/10 on the firmness scale, a light, gentle and flexible feel that conforms to your body.
  • Medium, a 5/10 on the firmness scale, the best of both worlds for an exceptionally comfy feel.
  • Firm, an 8/10 on the firmness scale, solid and stable support throughout your sleeping surface.
The Harmony Lux has 7 firmness options: * Classic Top (available in Extra Firm, Firm, Medium and Plush) and * Pillow Top (available in Firm, Medium and Plush).
