Mattress Firmness Explained: Choosing a Feel That Suits You
Mattress firmness describes how soft or firm a mattress feels when you lie on it. The rating is useful for comparing models, but firmness is subjective and can feel different depending on body shape, weight, sleeping position and the mattress construction.
What does a 1–10 firmness scale mean?
A lower number generally means a softer feel and a higher number a firmer feel. Treat DeepNap's displayed ratings as a way to compare its models, since there is no universal feel behind a given number.
Soft, medium and firm: general differences
Softer surfaces allow more sink at the top, while firmer surfaces tend to resist compression. Comfort layers and the support core both shape that feeling. Compare the actual construction, not just the label.
How sleeping position may affect comfort preference
Your sleeping position and how much you compress the mattress can influence comfort. Personal preference also matters. There is no single firmness score that suits every person in a given position or weight range.
Why firmness ratings vary between brands
Brands may use different materials, testing methods and labels. A model's thickness and layer arrangement can change the feel even when two mattresses share a rating. If possible, visit DeepNap to compare models directly.
Use the DeepNap Mattress Finder or book a consultation
The Mattress Finder can help shortlist options based on your preferences. You can also book a consultation to discuss the models, sizes and firmness available. The guidance is about comfort preferences, not medical assessment.
