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 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.

If you already know that you love a soft or firm mattress then follow your heart. However, if you are unsure you can follow this quick guide to make a selection:
1. Back Sleepers and Stomach Sleepers should choose the Firm Mattress
2. Side Sleepers and 'Free Style' Sleepers should choose the Soft Mattress
3. If either you or your partner is heavier than 220 lbs, the Firm Mattress may be the option for you.
4. If you are lighter than 130 lbs, the Soft Mattress may be the option for you.
