I’m sure many of you will agree with me when I say these firm mattresses are the best, especially if you have any back issues.

But the thing is finding a good firm mattress, the one that doesn’t feel like a concrete and doesn’t make you hurt all over, is hard and requires a lot of time.

To save you from headaches and from wasting your money on unsuitable mattresses, I want to share with you top 5 firm mattresses that have a potential to give you the sleep of your dreams.

Let’s see which one can be the best firm mattress for you.

Alexander Signature Series by Nest Bedding

alexander signature series nest bedding

Price: $1199


The Alexander Signature mattress made it to this list because it really can become the best firm mattress ever for you. I’ve tested the Luxury Firm model and it felt great.

Let’s take a look at its construction:

  • The base layer is a 6” thick high-density supportive layer.
  • The middle layer is 3” thick. It’s the proprietary Firm SmartFlow foam that provides support and allows the airflow to circulate freely through the mattress, helping you sleep cool.
  • The top layer is 2” thick gel memory foam. It contributes greatly to the cooling effect and releases pressure from your body pressure points.
  • The quilted cover is made of their special Thermic Phase Change Cooling Fabrics. It is soft and pleasant to the touch; plus, it’s breathable and helps you sleep cool.

In terms of firmness, I would say it’s 8 on a scale from 1 to 10. Thanks to the top gel layer, the mattress’s surface is bouncy and responsive. I feel like even heavier sleepers won’t sink into it that much.

“A great mattress doesn’t always have to be super firm, but it certainly has to support the right body parts properly.”

What is really great with that mattress?

The best thing about this mattress is the quality of the materials. It didn’t smell when I opened the box, which means there are no chemicals in the foam. And the combination of the high-quality materials (foam and gel) provides great comfort and a cooling effect. 

What is wrong with that mattress?

Now, it was really hard to pick the worst thing about the Alexander Signature mattress. I think that the worst thing you can experience is the mattress being too firm, which is a common issue for all firm mattresses. It takes time to adjust, especially if you are used to softer models.


High-quality materials

Great comfort levels when sleeping on the back and on the stomach

Sleeps cool

Provides a proper spine alignment

No off-gassing

Locally made

Great motion isolation


Might seem too firm at first

The cooling effect won’t work on a platform bed, as it restricts the airflow

Might not be suitable for side sleepers

Mediocre edge support

Overall, I have no complaints about this mattress whatsoever. I would recommend it to someone who experiences back pain and doesn’t usually sleep on their side. If you hate sleeping hot, this mattress will be a great option for you. It’s also suitable for couples, as it doesn’t allow too much of a motion transfer.


saatva mattress

Price: $999


Saatva is another best firm mattress you should consider. The manufacturer offers different levels of firmness (the hardest ones are Luxury Firm and Firm), so you’ll have options to choose from. I decided to test the Firm model and I wasn’t disappointed.

Here’s what’s hiding inside:

  • The steel coil base support layer.
  • The comfort layer with the coils wrapped individually. It contours your body without making you feel like you’re sinking into it.
  • The lumbar support layer, which is a memory foam layer that makes for pressure relief.
  • The euro pillow top layer, which is made of cushioning materials and provides additional comfort.
  • The dual foam edge support system. It allows you to have more sleeping space.
  • The cover is made of cotton and hypoallergenic fibers. It’s soft, natural, and breathable.

On a scale from 1 to 10, the Saatva Firm model rates 7.5-8. Because it has a comfort pillow top placed under the cover, it doesn’t feel too firm, even though it has coils in its construction.

What is really great with that mattress?

The best thing about the Saatva mattress is the comfort levels it provides. Even if you sleep right on the edge, you’ll still feel great. It doesn’t sag, it doesn’t envelop you like a quicksand, and it makes your back feel good.

What is wrong with that mattress?

Now, the worst thing you might experience with this mattress is to feel the lumps of the individually wrapped coils. This can happen if you’re a heavier sleeper. You’ll sink deeper and might find the mattress to be lumpy, even though it’s quite firm.


The innovative hybrid construction

Great support levels

Overall comfort in multiple sleeping positions

Locally made

Spine zone for proper alignment

No off-gassing

Has a chiropractic Seal of Approval


Doesn’t have that memory foam contouring feel

Might feel lumpy for heavier sleepers

Might become saggy in the spots between the individually wrapped coils

Only sold online, can’t try it at the store

Delivery issues

The Saatva mattress is an awesome option for people who want a luxurious construction for a reasonable price. It will suit solo sleepers more, as the motion isolation levels aren’t that high. It doesn’t sleep hot and supports the spine properly.


Price: $999


Amerisleep, another candidate to become the best firm mattress, features two firmness options. I picked the hardest one, the AS1 (which used to be called Americana). The company’s reputation and Amerisleep firm mattresses reviews of thousands of other people prove that this model deserves to be among the best.

Let’s see what it’s made of:

  • The proprietary Bio-Core support layer, which is partially made of a plant-based material, making it a more eco-friendly option.
  • The Bio-Pur cooling layer. It is breathable and has an open-cell structure, which allows the air to circulate freely and take the heat away from you.
  • The high-performance cover, which is made of the proprietary Celliant fabric and includes 13 thermo-reactive minerals.

Its firmness level is 8 on a scale from 1 to 10, which makes it a perfect option for back or stomach sleepers. The cooling effect it provides is average, but the overall comfort is rather pleasing.

“The majority of doctors recommend replacing your mattress for a new one every 8 years. They also suggest you turn your mattress clockwise to avoid sagging and ensure the supportive qualities of your bed.”

What is really great with that mattress?

The best thing about this mattress is the materials the manufacturer uses. Even though the company calls their mattresses 100% organic, they’re not, but they are at least 50% organic, which is more than the majority of mattress companies can offer. 

What is wrong with that mattress?

The worst thing about the AS1 is that, in my opinion, it’s overpriced. I mean, let’s face it: you don’t want to pay $1,000 for only two foam layers, especially taking into consideration the fact that they aren’t 100% organic and don’t provide a great cooling effect.


Rather firm and supportive

Partially organic

No off-gassing

Eco-friendly manufacturing process


Too expensive for its simple construction

Might be too firm for side sleepers

Only two layers

The cooling effect could be better

In general, the AS1 can become the most comfortable mattress for you. You will definitely like it if you appreciate extra support and the perfect middle amount of cushioning.


Price: $995


Helix would be the best firm mattress for people who want their mattress to meet their expectations. You see, the manufacturer builds a customized mattress for each buyer. Before ordering, you need to take a quiz, basing on which your mattress will be built.

You probably won’t be surprised when I say that I wanted to get a firm model. So, let’s see what it has to offer:

  • The base Dynamic Foam layer, which is the proprietary Helix material that feels like something between memory foam and latex.
  • Individually pocketed micro coils, which provide good pressure relief, create a bouncy feel, and distribute the body weight evenly. They also reduce the motion transfer.
  • The high-grade poly-foam top layer. This layer can vary in density depending on the support level and firmness that you want. In my case, it was very supportive and responsive.

On the firmness scale, my Helix would rate 9 out of 10. Let me calm you down right away:

It doesn’t feel like a hardwood floor.

To be honest, it lacks some extra cushioning But overall, it was comfortable for me.

What is really great with that mattress?

The best thing about Helix is how customizable it is. I mean, who will make a mattress with different qualities for its halves, for you and your partner? They will. All you have to do is choose how you want your mattress to feel, how much support you need, how important temperature regulation is for you, and how elastic in terms of motion transfer you want your mattress to be.

What is wrong with that mattress?

The worst thing about Helix is the fact that you never know what to expect. You can’t try the mattress at the store and you have no idea if the customization will actually work. You might find the mattress too firm, too soft, or completely different from what you were hoping for. Of course, the company’s return policy ensures the safety of your money, but it still can cause you a lot of stress.



Suitable for couples who have different mattress preferences

Locally made

No off-gassing

Environmentally certified


You can’t know for sure what you’re going to receive

Mediocre edge support

Might become saggy with time

Overall, I found my Helix to be very comfortable. It’s a great option for people who want a personal touch when picking a mattress. If you’re not afraid to take a small risk, chances are you’re going to love this mattress.

Loom and Leaf

Price: $1099


Is Loom and Leaf the best firm mattress? Well, it’s certainly one of the best. Made by Saatva, it comes in two options: Relaxed Firm and Firm (I decided to test the Firm option). The manufacturer claims that the mattress will feel comfortable in any position, and I found that to be true. That’s why Loom and Leaf is on this list: despite its firmness, it is comfortable for multiple sleeping positions.

“According to statistics, innerspring mattresses are sold the most in America, but they receive the lowest ratings in terms of the overall satisfaction.

Now, let’s move on to the most important part, the construction:

  • The dual high-density base layer plays a supportive role and has special airflow channels to provide a cooling effect.
  • The 2” transition layer.
  • The top layer, which is viscoelastic memory foam, contours the body but doesn’t allow it to sink in deep.
  • The cooling gel layer, located in the spinal area, which provides additional back support and helps you sleep cool. I found this component very comfortable and effective.
  • The cotton cover is organic, hypoallergenic, and breathable.

In terms of firmness, this model would rate 7 on a scale from 1 to 10. It is very responsive and bouncy, but at the same time it allows your body to sink in just enough to release pressure from the pressure points. I don’t know about you, but to me, that sounds extremely comfortable.

What is really great with that mattress?

The absolute best thing about Loom and Leaf is the cooling effect. It really works, even during the hot summer nights with the AC turned off. I guess it’s because of that additional gel layer, which is made of the same gel doctors use in hospitals to cool down the burns.

What is wrong with that mattress?

The worst thing about this mattress is probably the top layers and what can happen to them in the future. They might sag with time and might allow more sinkage for heavier sleepers. Even though the mattress is rather responsive, its top foams aren’t that dense. 


Great support for the back

No off-gassing

Cooling effect

Firmness level options

Comfortable in all sleeping positions


Might not be suitable for heavier sleepers

Not 100% organic, even though the manufacturer claims otherwise

Might sag with time

Can’t try it at the store, sold only online

One mattress can’t suit everyone, but Loom and Leaf is a great option for many people. I would recommend it if you want great support and hate sleeping hot. It’s also great for couples, as the motion isolation levels are quite high.

What Matters

To choose the best firm mattress, I had to do my research and test (I mean, sleep) a lot. The main criteria I paid my attention to were:

  • the overall comfort in multiple sleeping positions;
  • back support;
  • pressure relief;
  • construction;
  • price;
  • company’s reputation;
  • trial periods and guarantees;
  • materials.

Why Sleep on a Firm Mattress

If you’re in search of the best firm mattress, you should know about the benefits it can provide and what it can do for your body.

It’s been scientifically proven that too much cushioning can’t keep your spine in a neutral position and support it properly. The moderately firm mattress provides support for your spine and helps it align correctly in any sleeping position.

Also, when sleeping, your bones need to have some resistance to them and bear the most pressure. This allows the muscles, veins, and arteries to relax, which leads to a better blood circulation and simply helps you sleep well.

It’s always a good idea to consult your doctor before getting a firm mattress, especially if you’ve been sleeping on a soft one for years or have some health issues. It’s hard to transition from a soft bed to a firm one. Plus, some back illnesses don’t require a firm surface, so make sure to talk to your doctor first.


You’re probably wondering “So, which one is the best firm mattress?” In my opinion, it’s the Alexander Signature Series mattress by Nest Bedding. I’m not saying that it’s a perfect mattress for everyone (none of them are), but I was really sold on the combination of its great qualities. It’s very comfortable. It’s designed by a professional who’s been selling mattresses for over 20 years. It sleeps cool. And, most importantly, it provides excellent support for the spine. It might take you some time to adjust to its firmness, but it will be totally worth it.
