You will also learn how to choose the right one for your body and sleeping style. Everything is explained in very simple words so that anyone can understand it easily.
What Does Mattress Firmness Mean?
Firmness means how soft or hard a mattress feels when you lie down on it. It does not mean good or bad quality. A mattress can be high quality and still be soft. Another mattress can be high quality and firm.
Firmness is usually depend on a scale from 1 to 10:
- 1 to 3 – Soft
- 4 to 6 – Medium
- 7 to 10 – Firm
When you lie on a mattress, your body puts weight on it. If the mattress sinks a lot, it is soft. If it does not sink much, it is firm. Different materials also change the feel. For example, a Latex Mattress usually feels supportive and slightly bouncy. A Spring Mattress feels more responsive because it has metal coils inside. But remember, both types can come in soft, medium, or firm options.
Soft Mattress (Very Comfortable and Plush)
A soft mattress feels very gentle and cushioned. When you lie down, your body sinks more into it.
Who Should Choose Soft?

Medium Mattress (Balanced Comfort and Support)
Medium firmness is the most common and popular choice. It is not more soft and not too hard. It gives both comfort and support.
Who Should Choose Medium?
- People who change sleeping positions
- Couples with different sleep styles
- People with average body weight

A firm mattress feels hard and stable. Your body does not sink much into it.
Who Should Choose a Firm?
