Serta Killer Gel

Right from the get-go you can understand why the Serta Killner was given the National Sleep Foundations seal of approval. The moment you lie down on the bed you will feel the cushioned and voluptuous upper layer. The solid underneath works well with the upper layer cushioning.

On arrival at our doorstep, we found it was super easy to move for an extra firm foam mattress. However, just make sure that the mattress is in the correct room before unboxing. Once opened, although apparent, the Oder was fine. Sometimes the smell of the material can be an issue in the foam category. The reason for this 10-year is the 37% polyurethane foam pad and 63% polyurethane foam with instilled gel.

Balanced and Firm Memory Foam Mattress

What we loved about the Serta Killner was its balance of softness and firmness. We enjoyed the softened feeling on the back and lower body when lying on this mattress. One thing you may need to become acquainted with is the lack of seamed edges. This may be a little disconcerting to those who are used to feeling the seam edge. Many use that as a signal that they’re a bit to close to the side of the bed.

Conclusion – Is this a top mattress?

Whenever looking at a foamed mattress, it’s essential to observe the cooling efficiency.  As your body is in contact with so much surface, overheating can occur. However, the Serta Killner cut the balance perfectly. We found that we never woke up in a sweat or looking for a cold patch on the surface. An impressive feat for a foam mattress and especially a mattress size such as this one.

Allassea Gold Perfect Nite Hybrid

What better demonstration of a great quality hybrid mattress than the Allassea Perfect Nite. It combines their unique Spring Pocket coils system with the latest technology Swirl Gel Memory Foam. This combination delivers excellent all round body support as you sleep.

Let’s focus in on this “Swirl Gel Memory Foam” technology. It’s a stand out because it’s able to regulate the flow of air within the mattress. This means that your body never overheats while under the sheets. Furthermore, this same technology acts as a fire retardant.

Allassea Gold Perfect Nite Hybrid Extra firm / extremely mattressThe overall design of the mattress allows for it to lay upon bases that can be adjusted in height or on a normal foundation. So whatever base you have right now, it will work perfectly with that.

Features We Loved – Mattress size and mattress top

Two elements that stood out when we were testing this extremely firm item. Firstly, it’s reduction in the transfer of motion caused by tossing and turning. Great news for whoever will be lying next to you! You’ll be able to move around all you want, and they will not feel a thing. Secondly, the edge support was excellent on the Allassea Perfect Nite. This effectively makes the mattress top size look much more extensive than specified.

The only issue we found was that it was a little heavier than the other frim mattresses we tested. For example, when it arrived, it required two of us to get it upstairs.

 Reduces motion of partner
 Edge support is top notch
 Little heavier than expected
 Delivery issues with UPS

Klaussner Grandeur

The Klaussner Grandeur looks, feels and smells like an expensive mattress at a cost that you won’t believe.

When it first arrived, it came in an air compressed tube that made transportation up our stairs amazingly simple. We also couldn’t believe that they threw in a mattress zip cover. As those of us who have been doing their research will know, these are usually an additional (hefty) cost.

Extremely Firm Mattress

On set up, We were worried our bed would not have enough support for the current box springs frame. However, to my relief, this structure worked perfectly. It proves that you only need a standard bed frame to complement the Klaussner Grandeur.

This product was more comfortable than our Tempur Pedic mattress testing. The circulation of air was more efficient, causing less sweating than it’s competitor.

The only downside we could find was the topstitching of the pillows loosening after a few years of use. This leads to some of the foam falling out. However, these reports were rare.

Conclusion – Up there as one of the best extra-firm mattresses

One last pleasant surprise you will find is that the pillow tops are enormous compared to its rivals. Furthermore, they are removable so that you can throw them in the wash every so often. Overall, the comfort level feels like the mattress should be sitting in a higher price range. It nails the balance of firmness and softness.

 Super comfortable
 Can be used with any frame
 Large pillow tops
 Reports of loosening stitches after time
 Little more expensive

Otis Haley 150 Futon

We have decided to enter this “futon” into the mix because as we have come to find out about the Otis Haley, it’s far from just a “futon” mattress. This 60 by 80 by 6 inch item is a surprise packet straight out of the box. This is because the first thing you notice is that there are no creases. That’s not typical of a futon mattress.

However, once you unpackage the product from the tightly air sealed container, it firms up very quickly. The real fun begins with the first test lie down. You’re expecting the comfort of a futon but pleasantly surprised with the support of an expensive bed. The team behind the Otis Haley put years of research and development into this mattress. Resulting in a product that keeps it’s firmness for years while still being soft on your back and bodily shape. We have read many reports of this item helping customers overcome back pains and body aches. Even helping heal sleep-related injuries from previous mattresses.

Found Some Quirks – Top of Mattress

We did notice that the polyester can be a little slippery on the surface. Combine this with the minimal seam around the edges; one might look at investing in a topper. This would help slightly soften up the surface too for those who may find it a little too firm. The only other issue we could see was the slight smell that lasted for the first day or two. This eventually went away, but to be safe, maybe sleep on the old mattress for the first night.  Best to skip using the new mattress on the first night for a day of airing out.

Brentwood Gel Infused HD

Whether you are on the road or back at home, everyone just wants a peaceful nights rest. The Brentwood Gel Infused HD ticks every box as it’s suitable for all locations. Made right here in the USA, this mattress is a homegrown legend. Brentwood knows they are onto a good thing by supporting the product with a 25-year warranty. Yes, that’s right, 25 years! And from all accounts, this mattress goes the distance too. We have been testing this item for just under one year now and have not seen any wear or sag. This is a great firm mattress to have a softer layered top.

When it first arrives, you will find it a little clunky and large to move around. It’s not as compressed as other rivals we have tested here. As soon as you have the mattress in the bedroom, unbox it and let it breathe. It normally takes around a day to expand to the correct size.

Brentwood Gel Infused HD best extra-firm mattresses using memory foam technologyThis is a particularly popular item for those who are looking for a travel bed for those comfy rests nights in the RV. One of the major reasons for this popularity is its ability to squeeze comfortably into most tight spaces. All while not disturbing or sagging the even level of the top layer.

Conclusion – Extra firm memory foam

Lastly, we were most impressed with the complete lack of smell emitted from the mattress. Typically for a foam material, you may smell a hefty waft of fumes straight out of the box. However, Brentwood does not use toxic chemicals and flame retardants on their materials. This means there is no smell detectable on unboxing.

 Made in USA & 25 year warranty
 Squeezes into most spaces without compromise
 Non-smelling foam
 Needs a day to expand to size
No flame retardant technology

Queen Simmons Beautyrest Recharge Lydia Manor II

Looking for something in the mid to lower price range that is still extra firm? Well the Queen Simmons Beautyrest is the one for you. The mattress is optimal for stomach or back sleepers who are looking for that extra firm feel.

We found that in testing the top stayed cool with the “surface cool” fiber technology. The quilt has the technology directly sewn into the fibers. These fibers and materials all meet the health and environmental standards for polyurethane mattresses.

A mix of air-cool memory foam and a gel-touch foam results is a supreme level of comfort. In particular, this “gel-touch” mixes the best polyurethane foam with a gel substance. Effectively, it removes the pressure on your bones and body when you sleep. Further down the mattress is the air-cool memory foam that supports the lower back and spine.

For a lower cost extra firm mattress, we were impressed with the motion minimization. The Queen Simmons Beautyrest pocketed coil system absorbs motion like a memory foam mattress. Each coil is uniquely positioned to match the shape of your body.

Some extra firm mattress reviews mentioned these items showing signs of wear and tear after a few years. Some suggested that this bed is better for the guest bedroom where it would see less regular usage.

This is the our pick for a firm mattress at a lower cost. The mattress top supports the lower back very well and sustains its extra firm feel.

 Optimal for stomach & back sleepers
 Remains cool on body surface
 Reduces transfer of motion
 Possible wear and tear after a few years
 No warranty

Sleep Inc. BodyComfort Select 2000 Luxury

The Sleep Inc. BodyComfort makes our list as a great entry level mattress. It allows consumers to discover the benefits of the latest in bedding technology. Technology that is made in the USA and carries a 10 year warranty. The team over at Sleep Inc. really stand by the quality and comfort of their products.

We liked that from the moment of arrival, the bed was ready to be used. It arrives uncompressed and does not require any time to decompress (unlike some other items we have reviewed here). Furthermore, there was no Oder or gas smell when packaging came off.

Sleep Inc. BodyComfort Select 2000 Luxury best firm mattress because of mattress topWhen we tested the mattress out on the first night, you immediately feel the 5-Zone Convoluted Foam. A firm core is at the center of this technology, then overlaid with a soft cushion top. Inside is a 360 Degree Foam encasement which will ensure the edges of the bed stay nice and solid.

Now keep in mind this is an entry-level item that has had one or two reports of sagging. So far, after three months of testing this product, we have not seen such reported sagging. Also, we found it difficult to sit upright and read or work on the computer in the bed. The foam tends to allow you to sink in a little. This occurs when you put an excessive amount of pressure on one particular area.

Conclusion – Top mattress for a great price

It’s impressive how much firm mattress technology could fit into this item while keeping the price so low. Chase after the Sleep Inc. BodyComfort if you’re after a great deal.

 Made in the USA & 10-year warranty
 No smells
 Edges remained extremely solid after continuous usage
 Sinking on excess pressure points

Beautyrest Black Alexia

This is the second Beautyrest product we have reviewed here. Beautyrest knows how to make an extra firm mattress. One could compare this product to sleeping on a extra firm carpeted floor, without rock hard feeling. The soft thin layer of foam at the top adds enough cushioning to keep you fast asleep all night long.

This bed uses the Tencel sleep-surface climate technology. This innovative tech allows much more breathing room for the top layer. And that results in a regulated temperature for all the surface area in contact with your body.

Under the gel layer is the workhorse of the bed with the memory foam and pocketed coil system. This makes the bed firm while still conforming to the shape of your body.

We found that the mattress worked with three different bases we tested it on. It produced the same comfort level on each occasion.

This bed is a little more expensive than the others we have reviewed here. However, the quality in firmness and longevity would generally cost triple the price of this mattress.

 Gel layer absorbs movement of partner
 Best at keeping body surface cool
Meets the curves of the body with excellent cushioning
Little more expensive
 Extremely firm, maybe too much? (be warned)

Reasons to invest in an Extra Firm Mattress?

Extra firm mattresses were never all that trendy in the world of beds. It has only been in recent years due to the rapid increase in bedding technology. One just needs to delve back in time to the age of water beds. There you would see the full range of bedding trends. Most strange was that some people enjoyed the chance of motion sickness while trying to fall asleep? But I digress.

Here on ‘The Doctors’, they attempt to find the top extremely firm mattresses for your needs:

The focus shifted from the sensation of feeling to the science of sleep. Consumers demanded answers as to how to achieve a consistent good nights sleep. Science also started to link chronic medical issues to how a person slept on a mattress top. So years of research and trial and error push the mattress technology forward. This lead to less focus on contemporary bedroom ideas and more on curing that nagging back pain.

There were times when a mattress sat on box springs. The mattress itself contained an innerspring coil. For lovers of the firm mattress, the choice was between comfort and the support you were looking for in a bed. However, these times are long gone. Mattress technology has flourished to offer the consumer a wide variety of makes and types. Mattresses are often now classified as hybrid, latex, memory foam, or innerspring.

Advantages of Going an Extremely Firm Mattress

  1. No Sagging – Your body will be kept in the correct weight distribution while it rests. The means that there will not be additional pressure on any particular muscles or joints. In other words, you won’t be waking up in the middle of the night with pins and needles.
  2. king and queen extra firm mattressesCorrect Spinal Position – In the world of sleep ergonomics, science has shown that a reduced amount of padding will lead to having the proper spine position when sleeping. This is mainly because the weight of your body is distributed evenly across your bones. That, in turn, places much less stress on the spine.
  3. Better Breathing – A good mattress can stop your lower back from flopping into dangerous positions. That means your airways have much more room to breath. This leads to more oxygen intake and increasing the potential for the brain to enter a deeper sleep.
  4. Helps Keeping in Position – Many sleepers nowadays enjoy using items to ensure that keep in the correct sleeping position. Pillows, body pillows, and other similar objects fulfill this purpose and are much easier to position on a firmer mattress. This can mainly be the case with pregnant women who use pregnancy pillows for extra firm mattress lovers when sleeping.
  5. Out of the Bedroom – Research shows that a good nights sleep has a significant impact on your daily life. When your body slips into a deeper sleep, this simulates activity to mend soft tissue. Your body repairs muscle tissue and balances out insulin levels. And when you’re on a firm mattress, you dramatically increase your chances of this occurring.

What Type of Firm Mattress to Choose?


These mattresses come in two different varieties, continuous coil or open coil. The main difference between the two is in the springs. Open coils have individual springs molded together by a single wire. Whereas continuous coils are a particular length of wire whorled into the springs.

The main advantage of a coil mattress is the price. The technology is now a little dated, and the supply is higher, meaning there is more supply on the market. They are also somewhat lighter compared to the other types on the market.

However, the wear and tear is higher because the springs all function as one unit. This means if you roll over, you will probably wake up the person lying next to you as well.

Memory Foam

The latest market trends lean kindly on the memory foam technology. Many of the mattresses on our countdown list have memory foam. This market breakthrough started in the pillow segment where Tempur (a market leader in memory foam) took the industry by storm with their NASA developed version of the memory foam for extremely deep sleep. The material uses your body heat to form the perfectly sculpted mold for your body to rest within.

soft pedic

The main advantage is that once your body forms this mold, it is far less resistant to movement. This reduces joint and bone pressure while improving blood circulation.

However, in summer you may sometimes feel overheating. This is due to having so much of your body in contact with the surface of the mattress. Also, keep in mind that the cost of this technology is not cheap either.

Latex Foam

The composition of this type of mattress is a synthetic latex. It is explicitly designed to mold to a shape pressed against it. This is slightly different from a natural latex which originates from the trunks of rubber-producing trees.

latex vs foam

Latex has its advantages of not hosting the bed bugs because of the airflow through the material. This means that the materials respire and resist the pressures of overheating while being in bodily contact.

The firm mattress lovers will tend to lean towards this material. That’s because it’s a little firmer than its counterparts. However, you will find it is not a lightweight option. Furthermore, if you go cheap, you may see inconsistencies in the mattress surface appear over time.

Pocket Sprung

By far the most well-known types of mattresses on the market. They are renowned for having the springs stitched into every area of the fabric pockets in the mattress. Some retailers offer the choice of multiple sides that contain different firmness all in the one mattress.

The main advantage of pocket sprung bests are couples can sleep more soundly. As no matter what the shape or size of those in the bed, the springs are separate for each person. This springs can be adjusted too, meaning you can customise the firmness to your needs. These springs allow for excellent airflow in the mattress, meaning overheating is not as much of an issue.

Those with allergies to specific materials, however, may want to avoid this type of stuff. Lamb’s wool is often used to fill these beds.

How Do You Care for your New Mattress?

Tags and Receipt

Highly recommended that you hang onto your proof of purchase for any times you need to claim warranty service. Also, keep the labels on the mattress. These are important when requesting warranty service as they contain essential service information.


Your best option for keeping a your need purchase clean is to buy a mattress top protector for extra firm mattresses. The best mattress protectors are relatively cheap and can keep off the stains, liquids, and allergens.

Foundation & Frame Support

Be aware, the frame support and mattress foundation can affect your mattress warranty. Correct support will mean your mattress can last many more years. This is because the base and top will work together to distribute the weight evenly. Furthermore, the bottom can also be a safety concern. The foundation needs to be Fire Retardant Complaint in many states across the US.


Historical, manufacturers recommended mattress rotation every few months to extend the mattress lifetime. However, nowadays, mattress advancements mean this is not necessary.



One more important note, when you are moving it’s best to carry the mattress in an upright position. Also, cover it in plastic and never bend or place in an obscure spot. If storing the mattress for long periods of time, try to store it in a flat position.
