Mattress Firmness Guide
Updated: 5 hours ago
Firmness is personal. Your body weight, sleeping position, preferred feel and the mattress materials all affect how firm the same mattress feels.
What firmness levels mean
Firmness is not the same as support
Support comes from the mattress core and how it distributes your weight. Surface comfort comes from quilting, foam and upholstery layers. Compare both rather than choosing only by the word “firm.”
Body build matters
A lighter sleeper may experience a mattress as firmer because they compress it less. A heavier sleeper may sink further into the same model. This is why showroom testing is valuable.
For couples
If preferences differ, consider a balanced medium or medium-firm feel, a dual-comfort design where available, or a larger size that allows each person more room.
Frequently Asked Questions
What is medium-firm?
It generally describes a balanced feel with noticeable support and some surface cushioning, but ratings vary between models.
Does mattress thickness determine firmness?
No. Thickness shows the total profile; firmness depends on the density, springs and arrangement of the internal layers.
