Now, let’s take a quick look at what firmness is all about.

What is Mattress Firmness and Why You Should Care

The firmness of a mattress refers to the level of support. When you sit or lie down on a mattress, you sink in to some extent and are supported by its bulk as well. Since the main function of a mattress is to support the person sitting on or lying down on it, we need to ascertain just how it would perform.

Gauging the firmness of a mattress is important for your comfort, health, and quality of sleep.  Around a third of our lives or even more is spent in bed. We may suffer from sleeping on a mattress that is not suited to our preferences.

Levels of Mattress Firmness and Which One to Choose

Soft

If the firmness of a mattress is extremely low, we call it soft. These give very little support and will cause you to sink in the minute you sit or lie on them. This can be a very comfortable experience for side sleepers or those who suffer from hip/shoulder pain.

Medium-Soft

This is the kind of medium that provides something for those who like both softness and firmness in a mattress. This option is excellent if you want a properly comfy layer to soothe your pressure point along with a good core support. Such mattresses typically contain firm memory foam or a latex material.

Medium-Firm

If one wants a certain level of contouring in their mattress, this is a perfect choice. They’re great for those who want a good spinal support but aren’t comfortable with a completely rigid mattress. Such mattresses also have a nice level of bounce, unlike the softer varieties. These are mostly the popular choice for most mattress-buyers.

Firm

Completely firm mattresses are those that give the highest level of support. Very few mattresses get 10/10 on the firmness scale. There is no sinking when you lie on such a mattress. Some may enjoy this feeling, but others may find it highly uncomfortable. These mattresses are best for those who have back pain or live in humid climates.

What Types Of Materials Support Firmness?

Sturdy, tough materials that go into the making of the best firm mattress. First off, any mattress doesn’t have one kind of material, but several layers of it.

Firm mattresses usually have a very high number of coils at their base. This makes the support absolutely unyielding and solid. The uppermost layer, also known as the comfort layer, isn’t made of a soft material such as latex or wool. It would probably be of cotton or a firm sort of memory foam.

Finally, the packaging of a mattress matters just as much as the materials when it comes to firmness. The tighter the packing, the more firmness there will be.

How to Choose The Mattress Firmness

The first thing to understand is that there is no single firmness that’s just right for everyone.  Some companies may advertise ‘universal comfort’, but one may have a body shape, size, or personal preference that doesn’t match many others. When you do go mattress shopping, then, be sure to consider the following factors in choosing the right amount of firmness:

1. Comfort Level

The best firm mattress for you would also have a certain amount of comfort. There’s no sense in having good spinal support if you’re not comfy enough to doze off. This is somewhat subjective, so don’t worry about finding one thing uncomfortable even if your neighbor loved it.

2. Body Weight

The firmness of a mattress lies in how it responds to a person’s body. If you have a light body weight, your firmness preference would probably differ from a heavy person’s.

Those weighing below 130 pounds probably prefer a softer bed. A firm mattress will not get them any contouring benefits at all.

3. Preferred Position

If you sleep on your back, a firm mattress is a better choice. Anything too soft will give you back pain. If you sleep in two or more positions, you may want to consider something in the medium-firm range.

Other factors are climate, motion transfer, bed activity, and edge support. Be sure to look these up beforehand!
