Firmness is one of the fundamental features of mattresses to consider as you shop. Everyone has their own preferences. Those who weigh less or sleep on their backs or sides are typically better off with a plusher mattress while the majority of people can find what they’re looking for in a medium product. However, for those who weigh more or prefer to sleep on their stomachs, a firmer bed is more likely to offer the accommodation you seek.

If you’re in the market for a firmer mattress, there are a variety of products on the market to suit your needs. Let’s get a good understanding of the details you need to know and take a look at a few of our top picks to help you find the best firm mattress.

Benefits of Firm Mattresses

Many never realized they enjoyed a firmer product until they actually tried one. If you’re considering buying one after using a medium or plush product, you may be surprised at some of the often overlooked benefits you could take advantage of:

— Extra support

Too little support can be highly problematic for any sleeping type. Firmer mattresses mean more support, and this is especially true if you’re older and/or suffer with neck, joint, and back problems.

— Spinal alignment

The importance of proper posture doesn’t pause when you sleep. If you’re spine is out of alignment ⅓ of your life, you can expect problems to develop. A firmer product is often able to offer the support necessary for proper spinal alignment.

— Deep sleep

You want to enjoy 18-25 percent of your rest in a period of deep sleep. This is when the body temperature lowers slightly and most dreaming takes place. Firm products are able to offer the support you need to allow your spine, neck, and limbs to settle easily into a comfortable position. This is especially true if your current mattress has developed sagging.

— Weight distribution

If you suffer with misaligned joints or muscles, there’s a chance the catalyst lies in your mattress. The wrong amount of support will cause sagging in heavier areas. A firmer product can add the support you need.


Beyond Innerspring

Mattress trends and technologies are always changing. In the 70’s and 80’s, many were drawn to the idea of the waterbed, riding a wave night after night. Today, most have returned to the attraction to a tried-and-tested firm product for the support they need.

If you haven’t been mattress shopping in a while, you’ll be pleased to know that you aren’t restricted to innerspring products to get the firmness level you desire. Yes, you can still shop among a variety of quality innerspring products, but new technologies have allowed manufacturers to get more creative with materials and layer placements to allow you many more options. Just some include:

  • Memory foam
  • Latex
  • Hybrid mattresses

Keep reading, and we’ll take a look at excellent suggestions utilizing each of these material types.

Is a Firm Mattress Right for You?

There are many companies out there that offer the opportunity for you to make firmness adjustments after your purchase. Ideally, though, you want to start enjoying the right mattress sooner rather than later.

If you’re not yet quite sure if a firmer product will work well for you, it’s a good idea to do a self-analysis before you get too deep into shopping. While you do need adequate support to avoid misalignment of the spine, when you go too firm, you risk overcompensation that prevents the proper curvature you need to maintain comfort in your heels, buttocks, shoulder, and head.

Experts in sleep have reported that less cushioning has shown to encourage a neutral spine while in bed. This is because your bones take on the majority of the pressure. This allows both your muscles and blood vessels to relax, ultimately leading to better circulation and a higher quality of sleep. Furthermore, since your lower back won’t be as prone to sinking as a plusher product can cause, your airway is more open, allowing you to inhale more oxygen with every breath.

Four Primary Factors to Consider

  • Age
  • Weight
  • Pains you suffer with in your back, joints, and neck
  • Favorite sleeping position

Stomach sleeping can make you feel like you’re suffocating in your mattress if it is too plush. Firm mattresses can also help provide the support necessary for older people who suffer with aches and pains or those who carry more weight and tend to sink too deeply into medium or plush products. These factors should be carefully reviewed before you pick your next mattress.

Easily Facilitates Props

If you’re like me, you use your pillow for areas of the body other than the head. I find it very uncomfortable when lying on my side for my knees to lay on top of each other, so I’ll often place a pillow between them. Some of you may be big fans of body pillows that can be used for similar purposes.

Even if you don’t weigh much, sleep on your stomach, or suffer with aches and pains, you could still benefit from a firm product if you’d like to more effectively utilize your props. Firm mattresses offer more support for their effective use. Your body can adapt to a firm mattress and find it comfortable if you’re not used to it, although it can take a few weeks for these adaptations to take place if you’re used to a plush mattress.

Who Shouldn’t Use a Firm Mattress

As mentioned, firm products aren’t for everyone. If you’re reading, you likely already have reason to believe firm is good for you. If you’re still not quite sure, consider the following to ensure firm is best for your needs:

  • Have you suffered with lower back problems like arthritis, rheumatism, or scoliosis? Studies have suggested that firm products could cause more pain. Consult with your doctor before making a purchase.
  • Do you have a body mass index under 25? If so, you may find more comfort in a plush or medium product.
  • Do you like to sink a little bit into your mattress? You may not find the level of comfort in a firmer product that you’d like.

How to Gauge Firmness Shopping Online

As you shop online, there is a key piece of knowledge to keep in mind to get a good idea of firmness. Most companies will broadly categorize their products as plush, medium, and firm. The trouble is that these terms aren’t standardized. Comparing one mattress loosely categorized as firm to another may very likely result in finding one’s much firmer than the other.

The information you want to look for is the indentation load deflection. In a nutshell, 12 is very soft and 50 is very firm. You’ll typically find lower ILD’s in the comfort layer with much higher ILD’s nearer to the support base. A combined overall ILD of 31 or higher would be indicative of a firm product. The closer you get to 50, the firmer you can expect the product to be.

The Sleep Judge Firmness Test

We’ve hand-tested a number of quality firm products, and we offer a test on each that gives you a look into firmness. I apply my 130 pounds of body weight into an area of around nine by seven inches. Medium products usually sink between 6 ½ to 6 ¾ inches. Those that sink less are firmer. As you browse our top picks, you can access our full firm mattress reviews and see these tests for yourself to get a better idea of firmness. Here, we also share ILD’s when they’re available. (Some companies choose to keep this information under the radar to protect their formulas).
