Firmness Info

Everyone has their ideal comfort level. That's why we've designed this comfort selector tool so that you know exactly what you're jumping into. Select from 3 firmness levels:

  • Soft, a 2/10 on the firmness scale, a light, gentle and flexible feel that conforms to your body.
  • Medium, a 4/10 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 base model (CF1000 Hybrid) is a medium comfort. Choose the cooling upgrade (CF2000 Hybrid) model if you prefer a firm feel. Both the Max Cooling Upgrade (CF3000 Hybrid) and Max Cooling & Pressure Relief Upgrades (CF4000 Hybrid) offer a selection of feels - medium and plush and firm and plush.
