Advantages Of A Firm Mattress

In order to go and grab an ergonomic firm mattress you first have to understand why you should opt for a firm mattress and not any other type. Many users never become conscious of their firmer mattress until and unless they actually try one. If you are choosing to buy a medium firm mattress or an ultra-plush one, then you will be surprised by the advantages you can get from buying a firm mattress.

Additional Support

This is without a doubt the best advantage of a firm mattress. A firmer mattress implies additional support, and this is very much useful if you are an aged sleeper. This can also be great for people who have a neck, joint, spine or back problems.

Less support can be very difficult for any sleeper. Also with a firm mattress your lower back will not sink in as it does in a medium firm or plush mattress and so your breathing will not be compromised, and  you will be able to inhale more oxygen with each breath.

Spinal Alignment

When sleeping a good posture is incredibly important. If you get your spinal misaligned, then your health problems will start to grow. A firm mattress helps in providing you with good spinal alignment. Sleep experts also recommend that small cushioning will help in neutralizing your spine. With a firm mattress, your foam soaks up maximum pressure which permits your arteries, veins, and muscles to relax.

This allows for improved circulation and premium sleep quality.

Quality Sleep

When sleeping you must get 25% rest as this is the essential amount of rest needed by your body. As your body temperature starts to lower down due to the firm mattress, you will get the much-needed support for your limbs, spine, back, and neck. You will start to settle down in a comfy position and avoid any sagging.

Weight Distribution

If you have a problem with uneven muscles or joints, then a wrong mattress can provide you with weak support and lead to sagging in weightier body areas. A firm mattress acts as a catalyst and provides you with the support you need.

How To Decide On The Best Firmness Level?

If you are not sure on what firm level to buy in your mattress, you can perform a self-analysis before you go shopping. The main question when shopping revolves around the best firmness level.

Sleeping Position

This is the essential factor used in determining the firmness level ideal for you. When checking on a scale of 1-10, side sleepers require a range level of 3-6 firmness when sleeping. Similarly, stomach sleepers love a firmness level of 5-7 range, and back sleepers find the 4-8 range as the perfect level of firmness.

If you love sleeping in various different positions that you can find a balanced level of firmness to fit all your needs.

Weight And Body Type

Your firmness level depends on your weight and body type you have. If you are large, then you will need a thick and very firm mattress so that you have deep compression support. Large and heavy sleepers find that plush mattress may sink in due to their weight and pressure exerted on it.

Light sleepers are mostly disturbed with only the top layer of the mattress and not with the base and core so they can grab a mattress that has a firmer top layer only.


Mattress buyers should always remember that support and firmness and not the same thing. A mattress offering good support can be soft and encourage greater pressure relief. While you may want adequate support to avoid spinal alignment gone wrong, going firm makes sure that you get a proper curvature to get comfort in your legs, neck, shoulder, head, and hips.

If you are not certain what you want to buy, then you can always buy a medium-firm level mattress first and then go for a more firmer one.

What Features To Focus On When Buying A Firm Mattress?

A mattress is a pricey investment, and with a lot of new mattress models growing in the market with a number of manufacturers, it is important that you do your complete research before investing in your money.

Sleepers who are not familiar with the materials, jargon, firmness grading and other vital features must inspect these qualities when buying it. Keep on reading to find out more about the mattress features and which one to grab.

Material And Its Construction

When going through the most popular options, innerspring or coil spring support core is present in the majority of the mattress. This innerspring system is made from steel springs or rounded coils placed uniformly all through the core of the mattress for reliable and fine support.

These coils are steel rendered and so can get cooled and heated through a procedure known as tempering; this process helps in softening the coils to provide additional suppleness in your mattress. This process is also carried out on wire gauge.

The most conventional cushioning coil is the Bonnell coils and is produced in a curved hourglass shape. Offset coils consist of an hourglass shape and have a helical pattern joined together and straightened underneath the mattress; this construction helps in creating a hinge type motion when the mattress is compressed.

Continuous wire coils consist of numerous rows, and each row has a single length wire. These rows are then joined together by a helical structure from all sides. Encased coils also known as Pocket coils or Marshall coils are wrapped together in a cloth type material and helps in creating fabric strands used to join these individual coils together.

Then there is a latex material mattress; latex is derived from the rubber tree sap and has a soft yet elastic feel to it. Latex has the ability to contour to your body and is used in the comfort layer of mattresses. Latex also helps in supporting cores.


A firm mattress is great for sleepers who sleep on the side, back or stomach and weight more than 200 lbs. and have chronic pain. Firmness helps in keeping your back at a stable and comfortable position and avoids your body from sinking in while you sleep. This also reduces any soreness you may get. Firmness level can be determined by many things; to check the firmness grading of an innerspring mattress, latex and polyfoam read on below.

  • Innerspring Mattress

The first thing you can check for firmness of a mattress is the coil count; coil count is the major benchmark, and most beds have around 300-1000 coils whereas some come with more than 2000 coils. The number of coils is used in figuring out the contouring abilities of a mattress as well and is tied to the lifespan of a mattress.

Any mattress having more coils is more resilient.

  • Latex Mattress

The firmness level or softness of a latex mattress is tested via impression load deflection. Impression load deflection (ILD) is the amount of force placed on a mattress that causes it to compress the latex material by 25%. A high ILD number denotes that the latex is firm whereas a small ILD rating denotes that the latex is soft.

In general, latex mattresses comfort layer have a low ILD whereas the support core of the latex mattress has a high ILD.

  • Polyfoam Mattress

Polyfoam mattresses, on the other hand, are classified on two measures compressive modulus and density. Density is mass upon volume, and this clearly indicates the amount of compression your mattress sis able to handle and this directly relates to the durability of the mattress and its firmness.

Compression modulus, on the other hand, is the ratio of stress and strain for the mattress, and this helps in determining how much compression can be placed on the mattress before its foam structure gets permanently compromised.

Together, compressive modulus and density can help in figuring out the quality and firmness level of a polyfoam.

Ergonomics And Comfort

The most important feature in finding the perfect mattress is the comfort and support. You will need to look for a firm mattress that has the ability to push up on your body weight and counteract the pressure you place on it. You need to remember that your body is not a straight line and that if you sleep on your side, stomach or back, your body will curve and the mattress you choose must be able to support all your curves and arches.

Whatever mattress you choose, it must be firm enough to support your upper and lower back and should be soft enough to outline your entire body as well.
