there is no sign around the Emma Web-site of how firm this mattress is meant to get, but I found it around the softer end in the spectrum, and would rate it around a 6.five for firmness (with 10 getting the firmest). https://adsbookmark.com/story17164082/how-much-you-need-to-expect-you-ll-pay-for-a-good-emma-hybrid-premium-mattress
