Firm Mattress Buyer’s Guide

Firmness is a term used to define if the mattress feels more soft or more firm to the sleeper. A firmness level is measured on a scale from 1 to 10, with 1 being the least firm level and 10 being the firmest level. It is linked to the materials used in the comfort layer on the top of the bed. Most of the mattresses available on the market today are between a 3 (Soft) and an 8 (Firm). Mattresses with a firmness level below 5 (Medium) have a tendency to sink under your body and give you a cradle-shaped feeling. The models that have a firmness level between 6 (Medium Firm) and 8 (Firm) do not conform deeply to your body, but they do sleep much cooler than the softer mattresses.

The weight of the sleeper is directly linked to the firmness level. The soft firmness (1-3) is suitable for people with below-average weight (less than 130 pounds) because anybody with more than 130 pounds will have excessive sinking when in the bed, reducing the support of the mattress and causing the sleeper pain. Medium firmness (4-7) has excellent support for most weight groups, but those with above-average weight (more than 230 pounds) are at risk of sinking too deeply into the mattress and having pain. For these heavier individuals, the ideal firmness level would be Firm (8-10).

Common Qualities of Firm Mattresses

Firmer mattresses offer better support for people who have more weight. Heavier individuals can get proper pressure relief without sinking into the bed. Lighter individuals that have less than 130 pounds most commonly prefer Medium Soft (4) or lower firmness settings, people that have average weight from 130 to 230 pound most commonly prefer Medium (5) or Medium Firm (6), while sleeper with more than 230 pounds most commonly prefer Firm (7) or higher.

Apart from the weight of the body, the position you sleep in bed also affects the firmness preference. If you sleep on the side, you need to have proper spinal alignment, which softer mattresses offer. However, people that sleep on their backs already have good spinal alignment, and they don’t need a soft mattress and tend to feel more comfortable on firmer models. Stomach sleepers might also prefer firmer mattresses for the same reason as heavier individuals – they won’t sink. When sleeping on your stomach, additional weight is applied to your stomach area, causing you to sink on softer mattresses.

On top of that, softer mattresses have a shorter lifespan than firmer models, because they tend to sag after short ownership. On the other hand, firmer mattresses are less susceptible to getting indentations or to sag and they have longer lifespans because of that. Firmer models are also lighter, and easier to move because they have fewer layers that contribute to the weight of the mattress.

Of course, all of this may not apply to your preference. Every person is different and has different mattress preferences, so it is important to try different types of firmness to see if you prefer softer or firmer models. You can also find mattresses with dual firmness options to accommodate couples and individuals with oscillating sleeping preferences.
