Idle Dunlop Latex (Extra Firm)

What We Like

  • Eco-friendly; made without toxin or glue
  • Anti-microbial and hypo-allergenic
  • Pocketed coils resist motion transfer for disturbance-free sleep
  • Free shipping

What We Don't Like

  • May not sleep as cool as other options

Overall Thoughts: 

Of our extensive testing, the Idle Dunlop Latex is our favorite extra firm bed. The 6 inches of 100% natural dunlop latex on top feels amazing. Not many natural material beds we’ve found offer that much latex.
Dunlop latex has a really unique feel, in that it isn’t quite as bouncy as you might expect, but it also doesn’t cause you to sink into the mattress. It’s worth mentioning that this type of material is quite a lot heavier than other mattresses - especially ones made with foam. However, it’s also extremely durable and retains its shape.

What’s really impressive is the fact that you can choose a different firmness for each side. So if you and your partner have different preferences on how firm you’d prefer your side of mattress to be, you can customize it to be either medium or luxury firm. The medium choice is more on the firm side and the luxury firm options is extremely firm (9 - 10/10) This is almost like buying two separate mattresses for the price of one. This option makes the bed a great choice for all sleepers, everyone can find comfort with this product whether you like something on the firm side, or slightly more plush.

We also love that this mattress is flippable and has coils, which really helps in extending the already long, durable life of this mattress. We did mention that this mattress is heavy, but flipping is actually made quite easy thanks to the addition of 4 reinforced leather handles on the sides of the mattress. They’re very sturdy and make moving and flipping the mattress very easy.

Idle Talalay Latex

What We Like

  • Organic cotton cover is breathable and eco-friendly
  • Hypo-allergenic and antimicrobial
  • Reinforced handles for easy flipping and moving
  • Lasts two times longer than most mattresses
  • Free shipping

What We Don't Like

  • Significantly more expensive than Dunlop Latex counterpart product

Overall Thoughts: 

This mattress is a very close second and very similar to the Idle Dunlop Latex options. However, it’s more expensive. This is likely due to the fact the talalay latex product does require more manufacturing steps, whereas the dunlop latex doesn’t require as much processing.

We do need to mention though, that the feel of talalay latex tends to be more consistent and dunlop can vary at times. Additionally, this material is also extremely durable and long lasting and provides consistent comfort for the life of the bed. In fact, this mattress should last you 20+ years, two to three times in industry average. So while it might be more expensive, you won’t necessarily need to replace as soon as you might need to replace the other.

When comparing the feeling of these two different types of latex, talalay latex is definitely bouncier and very noticeably less dense than the dunlop latex. This means that this mattress is much lighter than the dunlop option, which not only makes it easier to move and flip, it is a bit cheaper and easier to ship.

Talalay latex has an open-cell structure which makes it quite breathable, keeping it cool while you sleep, whereas other types of material like foam can really heat up throughout the night.

Additionally, talalay offers more pressure relief and comfort, making it a good option for side sleepers - this is due to the fact that it has more of a bounce and isn’t quite as dense. So we definitely recommend this one if you want something firm, but still need some pressure relief and comfort factors as well for the ideal feel.

Like the Idle Dunlop Latex Mattress, this talalay latex version is also flippable and both sides can be customized to fit the preferences of you and your partner.

The Luff Plush Multi-Sleeper

What We Like

  • Compatible with adjustable bases
  • Each one is hand-crafted and made to order
  • Breathable stretch-fabric cover adds an extra surface breathability
  • Good for back and stomach sleepers
  • Suitable for most body types and comfort preferences

What We Don't Like

  • Quite difficult to move due to weight and no handles

Overall Thoughts: 

Luuf Beds has several different firmness options for adjustable comfort, but today we’re going to discuss the Firm Sleeper. We like this mattress because it’s definitely very firm, but doesn’t have that stiff feeling that we’ve experienced with other firm beds. This is due the memory foam and polyfoam comfort layer that makes it adaptive and responsive.

This mattress was specifically made for back and stomach sleepers, as well as people who experience lumbar pain, as it’s very firm and supportive where it matters. The mattress has 7 zones that house 1,074 pocketed coils that are precisely placed to help make up a durable and supportive core layer. These zones are specially designed to be aligned with the heavier portions of your body to give a balanced feel.

This mattress is a great option for sleepers weighing over 230bs. It can be difficult for people in this weight range to find beds that will still give the support they need for a comfortable night’ sleep.

We really love how plush the surface of this mattress feels while still being a fairly firm bed overall. The plushness really makes it easy to move around on it, while we’ve found that with some of the really firm memory foam beds it can be difficult to move around comfortably. It’s also very cool for being made of foam.
Memory foam mattresses are typically known for being very warm and absorbing body heat, but this one feels very good, thanks to 2 inches of gel-infused, temperature regulating memory foam layer. 

Diamond Brighton (Firm)

What We Like

  • Combines spring structure with firm memory foam
  • Excellent warranty and guarantees
  • Perfect for any sleeping position (back, stomach and side sleepers)

What We Don't Like

  • Might sag over time

Overall Thoughts: 

When we tried out this mattress, we were pleasantly surprised at the firmness beneath the soft topper. It’s made with a hybrid design, and materials. There’s plenty to love about this mattress, especially if you tend to switch sleeping positions throughout the night.

Whether sleeping on the side, back, or even stomach, it maintains the same equal firmness and support. If you’re like a lot of people, you might end the day with an aching lower back. Or if you don’t have the right mattress, you probably start the day like that too.

Lower back support is one of the areas the mattress really excels in. We were looking for a mattress that takes the strain off pressure points, but especially in the hips and back. It’s firm enough that you can really feel the support, but not too firm to be able to comfortably move around.

If you’re like many of us, and ease of movement is a reason you can’t make yourself get rid of your old innerspring, it’s time to let go. The Diamond Brighton mattress still has the feeling of structure you get with an innerspring mattress, plus the cradling of memory foam.

While it’s always hard to make the move to a new mattress, this was a pretty easy choice. First, it’s clearly made of high quality materials. Next, it comes with a reasonable price tag and an impressive warranty.

The mattress itself has a five year warranty, while the CertiPUR-US foams and materials are guaranteed for up to ten years. With that kind of confidence coming from the manufacturer, we knew it was a solid bet.

Another nice bonus: the base of the mattress is actually non-stick. That’s a huge deal, since no matter how much you move, this mattress wont. 

Plush Beds All Natural Latex Mattress (Extra Firm)

What We Like

  • Soft cover gives a cushy feel 
  • Seems to bounce back for support 
  • Doesn’t sink like memory foam
  • Good shoulder and neck support & pressure relief

What We Don't Like

  • Not as firm on edge support
  • Too firm for side sleepers

Overall Thoughts: 

Having a mattress that helps you sleep better is great. It’s even better when it’s eco friendly, chemical free, and helps keep allergies at bay. That’s exactly what we got with this mattress. While it may feel like it sinks a little more than your typical ‘extra firm’ mattress, it delivered spine support you just can’t argue with.

There’s plenty of bounce, so if you move about a lot during the night, that’s good news for you. We realized that while the mattress foam is definitely responsive, it’s much denser than we expected too.

One of the best things about this mattress was how the latex worked to even out the memory foam feel. When testing out foam mattresses, we felt like we were sinking more often than not. That didn’t happen with the Plush Beds mattress. There is some contouring to your body, but it’s just the right amount. It feels like the latex keeps you from sinking, while the foam eases pressure points.

We also noticed that the latex seems to push back when there’s weight on it. That adds plenty of support to keep your shoulders, neck and spine aligned, which is ideal for people with frequent back pain and pressure. The wool cover is nice and soft, so it doesn’t feel like other beds.

In essence, you get an almost plush feel from the cover alone, while the layers of the mattress keep you back and pressure points positioned for great sleep.

If you need a fairly firm mattress to support your back, but like the idea of a plush mattress, you’ll want to check this one out. It feels like a gentle firmness, which is a nice change from other brands.

Keetsa Plus

What We Like

  • Supportive layers ease back pain and pressure points
  • Pillow top upper layer gives a plush, but supported feel 
  • Excellent price point and warranty

What We Don't Like

  • Foam smell lasts a little longer
  •  Too firm for side sleepers

Overall Thoughts: 

It can be difficult to find a mattress that helps with back pain, and keeps you cool at night. Naturally, that was one reason we had to test out the Keetsa Plus mattress. If you’re a really hot sleeper, you know how hard it is to find a mattress that actually ‘sleeps cool’. With a 90 day trial period, taking it for a test run was too hard to resist. Of course, we were also interested in checking out a mattress that performs like latex, but without actually containing any latex.

Of the mattresses we checked out, Keetsa seems to have the most range for people of different heights, weights, and body types. It had a nice balance, which comes from the individually wrapped coils and special foam layers. We had plenty of support, but with the feeling of a more plush bed.

The upper layer is actually a pillow top, so you don’t have to lose the plush feel. Underneath, you can definitely tell there’s built up support, though. We felt like it was a good combination, and makes for a good compromise between partners that can’t decide between a really firm mattress and a soft pillow top style.

It’s certified eco friendly too, which we felt good about, considering how much waste can come from mattress manufacturing. You’ll love that it comes with a 12 year warranty.

Sleep EZ Natural Latex Mattress (Extra Firm)

What We Like

  • Made from 100% natural latex material
  • Has several layers that can be adjusted
  • Hypo-allergenic and anti-microbial properties
  • Coils extend the life of the bed
  • Good for all sleepers

What We Don't Like

  • Requires more assembly that most other mattresses

Overall Thoughts: 

When it comes to mattresses, you may feel like you have to choose one mattress firmness level for decades and hope it consistently provides you with what you need. But just like anything else, over time there can be different circumstances and different needs. This makes it harder to guarantee that what you need now will be what you need down the road. We love how Sleep EZ’s Natural Latex Mattress allows you to get the most out of your investment over the years. You get to adjust your mattress’s firmness through a multi-layer design.

Rather than just one layer of memory foam or coils, this mattress is made up of several different layers, including 100% natural organic latex. We love how these layers have different levels of firmness, allowing us to switch them around to get a firmer or softer feel to fit our needs.

Being natural latex, there are no harmful chemicals to worry about and no need to worry about your impact on the planet. You can also rest assured that the mattress will prevent heat from being trapped inside, making it too hot to sleep, as well as preventing noise and providing you with motion isolation.

This company takes pride in their product, with free shipping in the US, a 90-day risk free sleep trial, and between ten and twenty years of warranty protection. They also have an A+ rating on the Better Business Bureau, making them a very trusted company.

How to Choose an Extra Firm Mattress

To help you choose the right firm mattress, here are some important things to keep in mind.


Most mattresses are rated on a scale from one to ten to identify how firm the mattress is. One is the softest, plushiest option, while seven and eight are viewed as firm. For an extra-firm mattress, you want to look for something that would be a nine or ten on this scale.


Materials used to construct your mattress are crucial in determining both how firm it will be and how long it will maintain that level of firmness. Memory foam is a great material for plush or medium firm mattresses, but is not as ideal for firm mattresses. With extra-firm mattresses, you want as little memory foam as possible. Instead, you want to go with a mattress that relies on coil innersprings to provide the shape and support of your mattress.

Latex can also be a good option for those who do want some kind of topper on the innersprings inside your mattress. There are also latex foam mattresses that can be extremely firm, but is it important to make sure you pay attention to the specifications of the mattress to make sure it will be firm enough for your needs.


If you have tried firm mattresses, but you are not getting the results you are looking for, you may not be factoring in your weight. If you are over 130 pounds in weight, firm mattresses may not be ideal to support you. Your body has specific needs.

Heavier people may need firmer mattresses to make up for the lack of your mattresses ability to maintain more weight. If you're worried about your weight and how it works with a new bed, opt for a hybrid with coils as one of the at least three layers. A good mattress should have a core support layer, a mid section support layer, and a top layer. Each of the three layers helps create the overall firmness level you need in a premium mattress. Also check for a warranty, in case the mattress sags over time due to your weight..

Sleep Position & Different Sleepers

It is important to remember that the firmness of your mattress you require relates heavily to your sleeping position. Firm and extra firm mattresses are best for those who sleep on their stomachs or backs, protecting the natural alignment of your spine. For side sleepers, firm or extra firm mattresses are not recommended.

Some back sleepers love a firm mattress, other back sleepers don't. If you can, try out some mattresses in a store to determine your firmness preference. Buying a mattress in store will cost way more than buying online. However, different sleepers need to figure out what type of mattress they like. 

Side sleepers generally like something plush. Side sleepers won't like a firm mattress most of the time. These types of sleepers need a surface that provides more plush comfort, and a firm mattress isn't appealing for that reason.


Sagging is a problem for any mattress, but it can ruin a firm mattress. That is because sagging ruins your mattress’s ability to provide a straight surface to support your spine’s natural alignment.

Because that is the biggest reason to have a mattress this firm, you really need to look for a mattress that will resist sagging as much as possible. This is not only important for the middle, but for the edges as well.

A firm bed is less susceptible to sag, but it isn't impervious to it. Make sure you're investing in a bed that either has coils in the core to support it, or one thats made of entirely high quality materials like latex. The coils do a great job at preventing sag, but if you get a hybrid, latex, high quality mattress, this three factor combination sill virtually eliminate your issue with sagging, regardless of the firmness level.


When buying a firm mattress, thickness is a great indicator on just how firm it will be. This is because the thicker mattresses on the market include some sort of extra padding to make your mattress softer and more comfortable to lay on.

Even firm mattresses can end up with additional padding in the design. To help truly get the best mattress, you want to look for a mattress that has little to no top padding. Thinner mattresses help to indicate that there isn’t any extra unwanted padding. Looking at the internal makeup of any potential mattresses to make sure you are getting what you want.


While it does not directly impact your bed, you need to consider your pillows that will be used with it. If you are interested in using an extra-firm mattress, you need to make sure your pillows are not going to impact the purpose of this kind of mattress.
For example, extra firm mattresses serve to provide as little disruption to your spine’s natural alignment as possible. If you are laying on your stomach or back, but your pillows are very high, it can cause severe neck discomfort.

Frequently Asked Questions

Firm vs extra firm: Whats the difference?

Medium is the most popular type of bed, but some companies make beds specifically more on the firm side for people who need firmer support in a new mattress. A super firm mattress takes firmness to another level. Generally, a firm mattress won't have much give, but it'll have a plush top layer. An extra-firm mattress won't be as soft on top. Instead, it'll be firm throughout.

Can a firm mattress help with back pain?

The best mattress to help with back pain depends on your specific body type and sleep style. For heavier back sleepers, an extra firm mattress can absolutely provide the extra firm support that will help relieve back pain. With that said, a lightweight person, or someone who sleeps on their side won't find a new bed that's extra firm to be very beneficial for relieving back pain.

Should I get foam, latex or a hybrid?

Generally speaking, latex mattresses are the firmest by default. However, foam and hybrids can be made very firm as well. If you have a bigger budget for a new bed, latex is the best overall option if you're looking for a bed with firm support, great build quality, and one that will last longer than a traditional mattress.

Can I still use a mattress topper on a firm mattress?

Mattress toppers are normally used to add a comfort layer to an aging mattress, or one that doesn't have the firmness level or support you're looking for. If you buy the right bed to begin with, you won't need a mattress topper. A firm topper can still be added to an existing mattress to give it more comfort though.

Is firm still comfortable?

Many people hear "firm" and think you're sleeping on a rock, but that's not the case. Even the firmest bed will still have some give and support. Back sleepers and heavyset individuals are generally the type of people that find a firm bed more comfortable. When you're shopping for a new mattress, look for individually wrapped coils, at least a 10 year warranty, and keep in mind that most companies will let you return what you don't like.

I like firm, my partner likes soft, what can we do?

If you and your sleep partner disagree on the firmness thats right for your body, you can try a split king bed, and get different firmness levels to fit the sleepers style and your body. A split king is two twin beds on a single frame, and allows for a more customized sleep setup.

Will my bed frame work with a very firm mattress?

If you're worried about your bed frame with a firm bed, don't. A firm bed works with any bed frame, and can even be easier to secure than a soft bed. A firm bed has less sag and can be supported with less resistance. 

What warranty should I look for?

A lifetime warranty is great, but the industry standard is 10 year. A 10 year warranty gives you plenty of time to break in the mattress and have time to return it if anything goes wrong in that 10 year time period. Whether the comfort layer starts to sag, or something else about the mattress isn't good, a solid 10 year warranty is a good baseline for a bed.


It can be hard enough finding the right bed with just basic firmness. The challenge is made even harder when you need something extra firm. Despite how hard it was, we still managed to find these extra firm bed to meet the mark so start from our curated list and you’ll be on the right track!
