Buying Guide for Best Medium-Firm Mattress

  • Balanced Support and Comfort: A medium-firm mattress provides the ideal balance between support and comfort, offering enough firmness to maintain spinal alignment while still cushioning pressure points, making it suitable for most sleep positions.
  • Versatility for All Sleepers: This mattress type is versatile, catering to a wide range of sleepers—side, back, and stomach—by providing a supportive yet slightly plush surface that reduces discomfort and promotes healthy sleep posture.
  • Durability and Longevity: Medium-firm mattresses often strike a good balance between comfort layers and supportive cores, ensuring long-lasting durability while resisting sagging over time, making them a reliable investment for consistent sleep quality.

When your mattress is too soft or firm, you might struggle to sleep and then feel fatigued or in pain during the day. Medium-firm mattresses have a balance of cushioning and firmness to help sleepers rest pain-free. They’re not so soft that you’ll sink, yet not so firm that you could be sleeping on concrete.

The best mattress differs from person to person, but medium-firm mattresses may you help sleep cooler and are ideal for couples, and stomach or back sleepers. If you’re one of these, take a look at our favorite medium-firm mattress.

  • Couples looking for good motion isolation

The Zoma Hybrid mattress is one of the best medium-firm options we’ve tested. Our team was particularly impressed with how it blends comfort and support, making it ideal for various sleepers, especially athletes or those with active lifestyles. We noticed that its combination of foam and pocketed coils gives excellent pressure relief without sacrificing the responsiveness that many hybrid mattresses lack.

During our analysis, our testers appreciated its targeted zoned support, which provides firmer cushioning where you need it most, like the lower back and hips. Additionally, the breathable design and cooling gel memory foam kept heat buildup to a minimum, which is perfect for those who tend to sleep hot.

Balanced Support and Comfort
We chose the Zoma Hybrid because it offers the perfect balance between plush comfort and firm support, which we found works well for a wide range of sleepers, including side, back, and combination sleepers.

Cooling Technology

Our team discovered that the mattress stays cool throughout the night thanks to its gel-infused memory foam and breathable cover. This is a standout feature for anyone who tends to overheat while sleeping.

  • Cooling Gel-Infused Memory Foam: This top layer is designed to prevent heat retention and offer a soft, contouring feel.
  • Reactiv™ Layer: A responsive transition foam that prevents the sleeper from sinking too deeply, while enhancing mobility on the surface.
  • Pocketed Coil System: Zoned support with individually wrapped coils that offer targeted pressure relief and support, particularly for the lower back and hips.
  • High-Density Base Foam: Provides durability and maintains the mattress’s overall structure.

When lying on the Zoma Hybrid, the first thing we noticed was the cushiony yet firm support. The memory foam top layer hugs your body, relieving pressure on sensitive areas, while the pocketed coils provide bounce and prevent that “stuck” feeling. The mattress feels plush at first, but the deeper layers ensure you’re fully supported, particularly if you sleep on your back or side. Our testers found that the mattress worked exceptionally well for those with back pain, as it provides just the right amount of firmness without feeling too stiff.

“I noticed an immediate improvement in my sleep quality after just a week of testing the Zoma Hybrid. It’s firm enough to support my lower back but still soft enough to feel comfortable. – Sarah, one of our lead testers.”

Pros

  • The zoned support and memory foam ensure a perfect balance of comfort and pressure point relief.
  • The breathable design and cooling gel make this mattress ideal for hot sleepers.


Cons

  • While the Zoma Hybrid has solid support, the edges may feel less sturdy than the center for some sleepers.

How is Mattress Firmness Measured?

Firmness is measured on a scale from 1 to 10, with 1 being ultra-soft and 10 being ultra-firm. On that scale, medium-firm is a 6 out of 10. The scale determines the amount of cushioning and give a mattress has when you lay on it.

In technical terms, firmness is measured by ILD rating, or Indentation Load Deflection. It measures the amount of pressure needed to compress a layer of foam on a mattress by 25 percent. ILD is rated from 0 to 50, 0 being the softest and 50 being the firmest.

Manufacturers test ILD ratings using a weighted ball on a mattress. The heavier the weight needed to compress the mattress, the higher the ILD rating and thus, the firmer the mattress. Medium-firm mattresses fall between a 29 to 31 ILD rating.

When looking into mattress firmness, it’s important to note that firmness and support aren’t the same thing. Support is how well a mattress aligns your spine, while firmness refers to how soft or firm a mattress feels.

Mattress Firmness Scale

Here’s the rundown of all mattress firmnesses and their place on the firmness scale, including medium-firm:

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

Types of Medium-Firm Mattresses

Although you’ve already settled on mattress firmness, you now need to decide which mattress type is best. If you’re looking for some serious bounce, a hybrid mattress might be the right choice, but if you want a cushiony, pressure-relieving bed, look into memory foam or latex mattresses.

Memory Foam

Memory foam mattresses are luxurious with a hug-like feel. Many people love memory foam because it cradles the body’s curves exceptionally well, relieving pressure and isolating motion. Traditional types of memory foam are prone to sagging, overheating, and rapid wear, but modern memory foam has been modified to be cooler and more durable.

Hybrid

Hybrid mattresses are a combination of innerspring and foam mattresses. They have become increasingly popular because they have the support and bounce of an innerspring, but the pressure relief and contouring of an all-foam mattress.

Hybrid mattresses feature a pocketed coil support layer for bounce and increased airflow. The fabric casing for each coil also ensures they are quiet, durable, and won’t break through the mattress like they often do in a traditional innerspring mattress.  To be considered a hybrid mattress versus simply an innerspring, there must be at least 2 to 3 inches of comfort foam in the mattress.

Latex

Latex foam is a natural and durable material made from the sap of rubber trees. It provides great pressure relief and cradling while still maintaining a decent bounce.

Natural latex is a bit more expensive compared to memory foam or poly-foam. You can find synthetic or blended latex for cheaper, however, it’s not as durable as genuine latex and the synthetic materials are potentially toxic.

Latex foam has also been compared to memory foam numerous times. If you want to learn more about their similarities and differences, read our memory foam vs. latex guide.

Innerspring

Innerspring mattresses have been around since the 1800s and are one of the firmest types of mattresses. They have a spring support system and a pillow top made from wool, cotton, or foam—though these foams aren’t as durable most modern foams.

While innerspring mattresses are extra firm and supportive, compared to newer mattresses, innerspring mattresses are outdated and uncomfortable. The pillow tops aren’t great for pressure relief and don’t provide proper cradling, while the coils can be squeaky and prone to breaking.

Who Should Use a Medium-Firm Mattress?

Although how comfortable you are in bed is somewhat subjective, there are general recommendations for who should use what type of mattress. The biggest factors regarding mattress firmness are bodyweight, sleeping position, and whether or not you share a bed.

Stomach Sleepers

Stomach sleepers are typically comfortable on medium-firm or firm mattresses because they’re firm enough to keep their spine neutrally aligned. On softer mattresses, stomach sleepers’ hips are prone to sinking, curving their spine incorrectly.

Back Sleepers

An ideal mattress for back sleeping supports the spine while molding to the back’s curves. Back sleepers will definitely enjoy medium-firm mattresses for their mildly cushioned, but even surface.

In softer mattresses, back sleepers’ are at risk of hyperextending their spine, eventually leading to chronic pain. Medium-firm mattresses keep their backs aligned with their spine and properly supported, preventing pains, aches, and stiffness.

Hot Sleepers

A mattress’s breathability is primarily based on the materials in a mattress rather than the firmness, so soft mattresses aren’t necessarily hot and firm mattresses aren’t necessarily cool. More than firmness needs to be considered if you’re looking for a cooling mattress.

However, if you’re already a hot sleeper, the cushioning on a soft mattress might be a bit smothering, making you feel hotter and disrupting your sleep. A firmer mattress, like a medium-firm, is still soft enough for comfort but isn’t so soft that you’ll feel engulfed in its cushioning.

Plus-Sized Sleepers

A mattress for heavy sleepers needs to be supportive enough to take on the extra weight. People who weigh over 230 pounds need firmer mattresses to be properly supported and prevent bottoming out while lying in their primary sleeping position. Plus-sized sleepers might enjoy a medium-firm mattress to prevent them from sinking uncomfortably and feeling stuck in their bed.

On the contrary, petite sleepers who weigh less than 130 pounds will likely find medium-firm mattresses too firm, resulting in pressure points and stiffness.

Couples

Medium-firm mattresses are always a good option for couples with different firmness preferences because they usually fit most sleeping positions and provide good motion isolation. Some even consider medium and medium-firm mattresses to be “universally comfortable.”

That said, consider what you and your partner’s firmness preferences are. If you’re a side sleeper and they’re a petite back sleeper, a medium-firm mattress may be too firm. But if you’re a plus-size side sleeper and they’re a stomach sleeper, medium-firm works well.

However, if you and your partner’s firmness needs are completely opposite, getting a split mattress may be the better solution.

Benefits of Medium-Firm Mattresses

Many sleepers love medium-firm mattresses for their balance of cushioning and firmness since it suits many sleeping positions. Not only that, but this mattress firmness level can reduce pain and improve circulation. Let’s take a look at some of the benefits of sleeping on a medium-firm bed.

Minimizes Back Pain

According to a 2015 study, medium-firm mattresses are best if you struggle with back or lower back pain. In a 2010 study, 27 women experiencing back and shoulder pain noted their pain greatly reduced after switching their current mattresses out with a medium-firm mattress.

Medium-firm mattresses are well suited for back sleeping, one of the best positions for relieving back pain. Back sleeping on a medium-firm mattress promotes healthy spinal alignment and minimizes pressure build-up, reducing any back pain you may face.

Solid Edge Support

When a mattress has poor edge support, the firmness is uneven; you’re likely to only experience the proper firmness near the center of the bed. Most medium-firm mattresses tend to have excellent edge support and reinforced edges, meaning you have more usable surface area.

With better edge support, it’s easier to sit or lay towards the edge of the bed without the risk of falling. Also, it’s easier to get in and out of bed, especially for the elderly or individuals with limited mobility.

Improves Sleep Quality

When using a medium-firm mattress suited for your sleeping position, you may find yourself sleeping deeper and for longer. According to a 2009 study, sleepers who switched to medium-firm mattresses reported getting better sleep.

Improves Blood Circulation

If your mattress causes specific pressure on any specific body part, such as your lumbar spine, hips, or shoulders, the pressure can block blood circulation, causing numbness and discomfort. The gentle cushion of a medium-firm mattress can limit pressure, reducing tensions on the muscles, veins, and arteries.

Warranty and Sleep Trial Offers

Reputable companies will stand behind their mattresses by offering reliable warranties and sleep trials. It’s always best to look for mattresses with hefty warranties and sleep trials to protect your purchase.

Warranties

Warranties are guarantees from companies to protect your mattress from workmanship defects and sags beyond a certain depth, usually between 1 to 2 inches. For mattresses, warranties can last somewhere between 5 years all the way up to a lifetime warranty.

Companies have specific guidelines you must follow to keep your warranty intact, such as using certain foundations and not staining your mattress.

Sleep Trials

With the rise of online shopping and bed in a box mattresses, sleep trials are a must. They take the risk out of buying online and give you a sufficient amount of time to decide if your mattress is right for you. Even with in-store shopping, lying on a mattress for five minutes isn’t the equivalent of breaking in a new mattress and using it at home.

Sleep trials typically last between 30 to 365 days depending on the specific company. Most companies recommend trying out your mattress for at least 30 days—the approximate time it takes to break in a mattress—before deciding whether or not you like it.

If you decide to return your mattress, many mattress companies offer free returns and either donate or recycle your used mattress.

What’s the Best Firmness for a Mattress?

There’s no specific best firmness for mattresses, though some people might argue medium or medium-firm mattresses are best because they’re considered “universally comfortable” and suit most sleeping positions.

In actuality, the best firmness for you is based on your sleeping position, size, and whether or not you share a bed. We’ve already established medium-firm mattresses as suitable for back, stomach, and plus-sized sleepers, but other sleepers have different needs.

A mattress for side sleeping should provide more plush give than what a medium-firm bed can provide. Side sleepers are typically most comfortable on medium or medium-soft mattresses since they provide extra cushioning for sleepers’ widest body parts, the hips and shoulders.

Combo sleepers. switch between positions throughout the night. A medium mattress for combination sleeping is typically the most comfortable option.

Petite sleepers weighing less than 130 pounds should pick a mattress firmness somewhat softer than what’s recommended for their sleeping position.

Frequently Asked Questions

Are soft mattresses more comfortable than medium-firm mattresses?

Firmness and comfort aren’t the same, meaning a soft mattress isn’t the peak of comfort and a firm mattress doesn’t feel like sleeping on a stack of bricks. Firmness affects the amount of cushioning on a mattress, but the amount of cushioning you need to be comfortable is subjective.

For instance, a stomach sleeper using a soft mattress will notice their spine twisting incorrectly and causing immense discomfort. Similarly, plus-sized sleepers may feel trapped and unable to move properly on a soft mattress versus a medium-firm one.

So, based on your sleeping position and size, a medium-firm mattress can be more comfortable than a soft mattress and vice versa. For more information, check out our plush vs. firm mattress guide.

Do firmer mattresses last longer?

All mattresses wear out eventually, though how long a mattress lasts is dependent on the quality of its materials and construction more than the mattress’s firmness. High-quality soft mattresses should last just as long as firmer models. Both firm and soft mattresses will eventually wear down and need to be replaced.

Can a mattress be too firm?

Yes, some mattresses don’t have enough cushioning depending on the sleeper’s size or sleeping position. Without enough cushioning, a person can develop pressure points and wake up sore on some mattresses.

If you’re a petite or side sleeper, you’ll likely find medium-firm mattresses too hard and painful. Instead, a medium or medium-soft mattress is a better choice for petite or side sleepers.

If your mattress is too firm and you’re unable to return it, a soft mattress topper provides needed cushioning for sleepers.

How can I make my mattress firmer?

If replacing your mattress is out of the question, there are a couple of easy ways to firm up your current mattress.

Adding a firm mattress topper to your mattress is arguably the most effective way to alter your mattress’s firmness. If you’re looking to drastically alter your mattress’s current feel, a thicker topper (3 inches or more) is best, but if you just need a little extra boost of firmness, a thinner topper (1 or 2 inches) is ideal.

Another easy way to firm up your mattress is by placing a bunkie board between your mattress and its current foundation. Bunkie boards are 1 to 3-inch planks of plywood built to bolster your mattress and enhance its firmness.

Should I get a firm or medium-firm mattress?

Most sleepers will find a medium-firm mattress perfectly comfortable. That's why it's often considered a "universally comfortable" bed, along with medium mattresses. However, stomach sleepers may benefit from choosing a firm bed over a medium-firm mattress for better torso support.

Is a Medium-Firm Mattress Right For You?

If you’re in need of extra support, but still want a bit of cushioning for your body, consider a medium-firm mattress. They offer an even surface to prevent stomach, back, and hotter sleepers from sinking into their beds. Some couples and plus-sized sleepers will also enjoy the balanced feel of a medium-firm mattress.
