One of the most decisive factors, when people embark on their mattress purchase, is whether a mattress is soft, medium, or firm, i.e. the level of firmness it offers. Of course, while this is a matter of personal preference and taste, there are some generally accepted rules and a scale of firmness which is used to help you decide whether you should get a soft, firm or any of the in-between options like medium soft or medium firm.
In case you are wondering, choosing the right level of firmness is critical for your health, as it will ensure a restful sleep. On the other hand, if you choose a firmness level that is not appropriate for you, then it is likely you will toss and turn a lot during the night, experience discomfort and pain, which can become chronic if you continue sleeping on a mattress that has the wrong firmness for your needs.
In this sense, it is important to be well-informed about mattress firmness before buying your next mattress, so as to avoid any disappointment. This mattress firmness guide is about to give you insights into some basic industry rules on how to tell whether and how firm or soft is a mattress, as well as to decide which suits you best.
So, get ready to know all about:
What does mattress firmness mean?
Mattress firmness refers to the feel or touches you experience upon laying on a mattress. Sensing that a mattress is cushioning enough or a bit too stiff, are all indications of how firm a mattress is. Generally speaking, you should not be looking for an overly soft or overly firm mattress, as either can harm your joints or back, causing pain and discomfort. In this sense, you should avoid extremes in terms of mattress firmness.
It is always important not to stay with an overly worn out mattress, whose firmness has changed over time, alongside other features like comfort, support etc. While you save a few money in the short-term, it leaves much room in the long run for serious health issues which can cost far more.
So, be prudent and get a great mattress with just the right amount of firmness. Softness or firmness is determined mostly by the comfort layer in your mattress, which could consist of a vast array of materials including memory foam, latex, innerspring, poly-foam, gel and a combination of different kinds in a hybrid mattress. Finding the perfect firmness will ensure the so much needed comfort.
Difference between firmness and support
Firmness doesn’t equal support. Many people tend to confuse the two terms, however, it is important to distinguish them in order to be clearer on what you are looking for when you search for the best mattress for you.
To set things right, firmness is mostly about how you feel when lying on a mattress, how soft or firm it feels. Support, on the other hand, refers to how well a mattress succeeds to maintain your spine in proper alignment and relieve pressure points, and this is regardless of how soft or firm it feels.
The most suitable mattress for you is the one which caters for both appropriate support and just the right amount of firmness for your individual needs. For instance, you should consider how well a mattress contours to your body’s natural curves in the position you sleep.
Generally speaking, firm mattresses tend to provide more substantial support, whereas a softer mattress is likely to offer support with fewer pressure points.back to menu ↑
Firmness is subjective and varies depending on the manufacturer many times. To help ensure consumers choose the best firmness for their needs, mattress experts have come up with a firmness scale, which includes a measurement on a scale of 1 to 10, where 1 refers to a feel as soft as a pillow, and a 10 is stiff as a rock.
Extremes are usually avoided by manufacturers, yet it is best to be familiar with the firmness scale so as to know where about a mattress sits in.
Below is our overview of a firmness scale, ranging from very soft to very firm, with explanations and a table accompanying the text on how each level feels and corresponds to certain mattress characteristics.
What is Universal Comfort?
When talking about firmness, it is often the case that you will hear the term “universal comfort”. This is an attempt of manufacturers to produce a mattress that will accommodate everyone’s preferences and sleeping positions.
It is not easy to succeed so, however most “bed in a box” brands now adhere to this policy as the universal comfort model seems to appeal more consumers, in response to the saying “one size fits all”.
Despite claiming to offer universal comfort, which means a firmness somewhere between 5-7 out of the firmness scale, as a medium to medium firm feel, it is often the case based on our experience and personal testing that manufacturers design mattresses that feel firmer or softer than expected.
Noticeably, universal comfort does not only refer to the firmness level, but also the comfort, support, weight distribution, contour, bounce, and responsiveness of a mattress. A great universal comfort feeling mattress strikes the perfect balance between all of the above features.
In this sense, the universal comfort model was made to cater for varying needs of a majority of sleepers.
Dual firmness or multiple options
Given the difficulty to provide just the kind of firmness each individual needs, some high-end brands do not follow the universal feel model and instead offer the option to choose your preferred level of firmness.
This versatile design which usually includes a medium and a firm option, namely a dual firmness, is a great choice if you want to customize your firmness level to get it right.
Some manufacturers can go as far as accommodating for different firmness options in the same mattress. This is exceptional if you are a couple for instance and each partner has different firmness preferences. Just choose between the different brands offering such personalization in terms of firmness, like Helix does, and you will end up with just the appropriate firmness for each sleeper.back to menu ↑
