What firmness means
Firmness describes how the mattress feels when you lie on it. A softer mattress allows more surface cushioning. A firmer mattress gives a more supportive and stable feel.
Firmness is personal. Two people can lie on the same mattress and describe it differently because body weight, sleeping position and comfort preference all affect the experience.
Soft mattresses
A soft mattress can feel cushioning and gentle on pressure points. It may suit people who prefer a more plush sleeping surface.
However, a mattress that is too soft may not give enough support for some sleepers. If the body sinks too far, the mattress may feel less stable.
Medium mattresses
A medium mattress, such as the Deep Sleeper Comfort, is often chosen as a balanced option. It can provide a mixture of comfort and support, making it suitable for many general users.
Medium comfort can be useful when you do not want a mattress to feel too soft or too firm.
Firm mattresses
A firm mattress, such as the Deep Sleeper Back Care, gives a more supportive surface feel. Some customers prefer this because it feels stable and less cushioned.
A firm mattress may be a good choice for people who dislike sinking into the mattress, but it still needs a suitable comfort layer to avoid feeling harsh.
Check the full product details
Do not choose by firmness alone. Check the foam layers, mattress depth, cover and intended use. These details help explain how the mattress will feel and perform.
Where you already know the firmness and foam combination you prefer, the custom foam mattress builder allows you to choose the support grade and any upper comfort layers separately.
