How do I select the firmness level of the mattress when purchasing a CopperFlex Essential?

Mattress Thickness & Firmness Guide

When you select a mattress thickness, you're also choosing the firmness level—each height is designed to offer a different feel:

• 6" Mattress – Firmest Option
  Firmness Level: 8/10 (on a scale where 1 = softest, 10 = firmest)

• 8" Mattress – Firm Medium
  Firmness Level: 7/10

• 10" Mattress – Medium Firm
  Firmness Level: 6/10

• 12" Mattress – Medium
  Firmness Level: 5/10

• 14" Mattress – Soft Medium
  Firmness Level: 4/10
