Best Firm (Hard) Mattress Reviews 2025

People prefer firm or hard mattresses for a variety of reasons. Among these are stomach sleepers, for whom a firm mattress is best, and also back sleepers. The latter is split between those who prefer a medium firm mattress and those who prefer a hard mattress.

The terms are relative, of course, and what is firm to one person might be medium to another. However, we have checked out a number of the firm or hard mattresses and chosen our best six for 2025. If you are a side sleeper, it is unlikely that any of the mattresses reviewed below would suit you, since you need a softer top to absorb the pressure of your shoulders, hips, and knees.

Here are our top 6 firm mattresses for 2025

NOTE: The comfort/firmness levels quoted in these firm mattress reviews refer to firmness levels on a 1-10 scale, where 10 is firmest. Where any deviate from this, that is with 1.0 as firmest, it will be stated.

3. Helix Mattress: Best Firm Mattress for Couples and for Customizing

When you order a mattress from Helix Sleep you must fill complete an online quiz or questionnaire. The information is used to recommend a mattress tailored specifically for you. If you sleep with a partner then, if you wish, each side of the Helix mattress can be designed specifically for each partner. The left-hand side can be soft and comfortable, while the right-hand half can be firm and hard.

The same is true for a stomach or back sleeper, who prefers firm mattresses, and a side sleeper who prefer softer top surfaces. Heavyweight sleepers with lightweight partners will find this a perfect solution to their problem. Twilight and Dawn are the two firm mattresses in the range, though they are modified to suit your needs as discovered in your quiz answers. If you prefer a super firm mattress, then they will make it for you.

The mattress consists fundamentally of three layers, namely:

1. A proprietary Helix Dynamic Foam.
2. A cooling transition layer of polyfoam.
3. Individually pocketed micro coils.
4. A base support layer of polyurethane (polyfoam).

Helix Dynamic Foam is a proprietary synthetic foam, the composition of which is not revealed. It possesses the properties of latex and memory foam, with very low motion transfer properties. It is bouncier than memory foam and does not make you feel held down enclosed in your bed as memory foam can do.

It is not possible to state the relative thicknesses of each layer since these will depend on your quiz. There could be a significant difference between individual customers; easily by up to 4 inches. The density of the foams can also be personalized. If you are a heavyweight sleeper, then the density of the top two foams may be increased for a firmer mattress.

Dual Extra Helix Mattress: One of the advantages of the Helix mattress is its dual capability. The Dual Extra option can be used to create a mattress where one side is firmer than the other. Hence, a heavyweight guy and a lightweight woman can sleep comfortably on their own comfort or firmness level. If you like a hard mattress (say 7 -8 firmness level), then you can have that tailored to your needs while your lighter partner can have a more comfortable mattress (say 4-5 firmness level). The same is true of different sleeping positions.

4. Loom and Leaf Firm Option: Best Hard Mattress for Cooling

Loom & Leaf, manufactured by Saatva, offers two versions of its firm mattress: the Relaxed Firm version with a comfort level of 6 -7 on a 1 – 10 scale where 10 is firmest. The Firm version is harder, around 8 – 9. It is the Firm version we are reviewing here, though there is little between them other than the foam density.

The Loom and Leaf Firm mattress is an ideal firm or hard mattress for couples due to its excellent motion isolation and responsiveness. When you move position, the mattress rapidly reverts to its original smooth shape. It is also ideal for stomach and back sleepers.

The mattress comprises four layers:

1. The top 2” layer is an enhanced 4lb conforming convoluted foam fitted with a cooling gel panel. It conforms to your body shape, providing comfort plus excellent support for your pressure points: shoulders, hips, buttocks, and knees. The egg crate design to provide a good flow of air and the lower back area of the unconvoluted side is covered with a panel of cooling gel.
2. The second layer is 2.5” of memory foam (5 lb density) which provides deeper support.
3. The third layer is a 2” loft pad that transitions the sleeper from the memory foam layer above to the dense support foam beneath it.
4. The bottom layer is a 5.5” layer of high-density support polyurethane foam for maximum base support.
5. Cover: The cover is made from organic cotton which is quilted with 5/8” of foam, and includes a natural thistle flame retardant.

This mattress has a chemical-free flame-resistant barrier of organic New Zealand wool which covers both sides, top, and bottom. Over this is a cover of quilted organic cotton.

The beauty of Talalay latex is that it easy to create foams of differing densities and support. The Zenhaven mattress has five zones, each providing a different level of support for those areas of your body that require it. The lumbar (lower) area of your back is supported more than your shoulders and hips which like a more comfortable level of give. The base layer is also of 100% Talalay latex.

If you find the Winkbeds Plus too hard for you, you can change it for the Luxury Firm or Firmer options during your 120-night trial. Stomach sleepers benefit from the zoned latex and spring units since they provide pressure relief for areas that could become painful is pressed onto a hard mattress with no give. Also, if your hips sink into the mattress your back can become arched in an unnatural position, also leading to back pain. Zoned areas help to prevent both of these occurrences.

Who Benefits From a Hard Bed?

We have presented above our six best firm mattresses. Who would deliberately choose a hard mattress rather than a softer mattress that most people might believe to be more comfortable? The general answer to that question is those that sleep on their back or stomach, and also heavier weight people would normally benefit from a firm mattress.

Zoned Mattresses: A firm mattress helps back sleepers to lie flat with the correct alignment of their spine. Stomach sleepers also benefit in this way, although it is important that they do not sink into the mattress, particularly the hips, or their back may arch in an unnatural angle leading to pain. That’s why we recommend a zoned mattress such as the DreamCloud Luxury Hybrid Mattress which provides areas of less and more support where needed.

Heavyweight Sleepers: A hard mattress is also best for heavyweight people who may sink too much into a softer mattress. Even heavy side sleepers may find a firm mattress to suit them best. If your weight is around 230 lb or more (104 Kg+) you may also find a hard bed better for you, particularly a zoned mattress, which may even be suitable for heavy side sleepers. The majority of the mattresses in our review, including our top two, have zoned areas, although those without them are also excellent options.

Lightweight Sleepers: Those weighing less than 230 KG, particularly significantly less, are best with a softer mattress – for example, the Softer or Luxury Firm Winkbeds mattress or a bespoke Helix mattress. If you are light in weight but have a heavy partner, then check out the Helix Dual Extra mattress.

The above firm mattresses may not be suitable for everybody. We have tended to focus on back and stomach sleepers. Although these choices are suitable for heavyweight people, there are other options that have been designed specifically for those over 200 lb or more. Check out our Best Mattress for Large or Heavy People Review for other options.

Buyer’s Guide to Best Hard Mattresses

Here is some advice on finding the best firm or hard mattress suitable for your needs. A lot depends on how firm or hard you want your mattress to be. You can judge this from the mattress description: Plush (definitely not firm), Medium Firm, Firm and Extra Firm or Firm Plus. There are others in between these, but it’s the latter three we are interested in. They can each mean something different between manufacturers.

Unless there is a pressing need why not, the majority of people will prefer a medium firm mattress. This offers a balance between comfort and support. Both are very important to most people when they consider the sleeping surface they will have to live with. We have explained the differences above, and why some people prefer harder or firmer mattresses.

Comfort Levels

Mattresses are usually expressed numerically on a scale of 1 – 10 when 10 usually refers to the hardest mattress. Occasionally, you may find a scale where 10 is softest and 1 is firmest. The more popular scale relates to the following comfort levels:

• 1-2: Very soft
• 3-4: Soft
• 5-6: Medium
• 7-8: Firm
• 9-10: Very firm

Various different mattress companies may use different descriptions, such as 5-6 being Plush and 6-7 being Medium Firm. However, that is simply terminology. The closer to 10 the harder the mattress and the closer to 1, the softer.

Materials

The materials used to construct the mattress may or may not be important to you. The three most popular materials are memory foam, latex, and innersprings. Innersprings often appear in reviews as hybrids: a combination of innersprings and foam. Find out about the various types of foam mattresses here.

Memory Foam: Memory foams are not firm due to their nature. This type of foam may be used as a thin top layer on a firm mattress in order to offer a slightly more comfortable sleeping surface, with the support foams or innersprings below it. On the other hand, it can be used as the primary foam in soft mattresses with firmness levels of 1- 4 or as thicker comfort layers in medium-firm mattresses.

Pros:

• Contours closely to your body shape.
• Reverts back to original shape and adjusts quickly to your new shape when you move position.

Latex: Latex is more responsive than memory foam, meaning that it rapidly adjusts to changes in pressure. When you change position in bed, a latex mattress will get back to its original shape faster than a non-responsive foam. Latex foam is generally natural unless the latex is synthetic. It is bouncier than memory foams and better for young couples who like a bit of a bounce at nights.

Pros:

• Latex is a comfortable foam to lie on.
• Latex foams conform to your body shape, though perhaps not as well as memory foams.
• More affordable than memory foams.
• Bouncy and responsive

Innerspring: Innerspring mattresses are usually firmer than foam mattresses. Even if the mattress has layers of foam over the steel spring unit, it is still usually firm to very firm. Many modern innerspring units use individually pocketed steel coils or mini coils. Most people are familiar with the properties of innerspring mattresses.

Pros:

• Pocketed coils can help with motion isolation.
• Provide a firm layer for medium to hard mattresses.
• The space between springs can cool down the mattress.

Hybrid: A hybrid mattress generally refers to an innerspring mattress with memory foam used for comfortable contouring to the body shape. Some latex/innerspring mattresses are also described as being hybrids. Generally, hard mattresses and some medium firm-mattresses contain innerspring units. Almost all firm mattresses have a core of steel coils, hybrid or not. Four of our top six above contain steel coils in one form or another.

Pros:

• Conforms to the shape of your body.
• Can adapt to various sleeping positions and body types.
• The spring unit helps to keep the mattress cool.

Edge Support: Edge support can be important to many people, though not necessarily essential. It is often a necessity for those sleeping with a partner. It is an important property to many young couples, where good edge support can prevent them from falling off the edge of the bed in their passion. If this is you, then look for that property in your mattress. Often a larger bed (such as King rather than a Queen) precludes the need for edge support since there is more room to move about.

Cooling Properties: This can be a very important factor for some people, particularly for couples. You don’t want to wake up sweating in the middle of the night. The DreamCloud, Helix Mattress, and Loom and Leaf Mattress are the two best for cooling in our top 6 firm mattress review. Gel-infused memory foam, gel pads, innerspring units, and superior airflow are used to cool your mattress down.

Importance of the Pillow

If you are a stomach sleeper your choice of pillow will be very important. Too thick a pillow will raise your head too much, putting a strain on your cervical (neck) vertebrae and your neck muscles. It is important that your whole spinal column is straight when sleeping. Check out our Best Pillow for Neck Pain Review and look for information on the stomach or front sleepers.
