Best Firm Mattress

Lara Vargas


The statement to “always choose a firm mattress,” is false. Firm mattresses are not for everyone, however, they are excellent choices for back and stomach sleepers— they need a firm mattress to prevent heavier sections of the body, like the hips, from sinking in and throwing the spine out of alignment.

In this article, we review our favorite firm mattresses and offer tips on how to choose the best firm mattress for your needs.

  • BioPur® layer is thin but cool, its airy design encouraging heat dispersion.
  • Bio-Core® is a durable material responsible for Amerisleep's industry-leading warranty.
  • BioPur® foam eases pressure points without trapping a sleeper.
Recommended for...
  • Stomach sleepers seeking a firm mattress to keep their bellies from sinking into their bed.
  • Back sleepers interested in a firm mattress for ideal spinal alignment.
  • Heavyweight sleepers looking for a firm mattress to withstand their body weight.

The Amerisleep AS1 our recommendation for firm mattress seekers. Standing at 10 inches, it includes a 2-inch layer of BioPur® and an 8-inch layer of BioCore®. It features a lightweight, breathable cover to keep air moving throughout the mattress.

Both Bio-Pur® and Bio-Core® foams are exclusive to Amerisleep. The open-cell structure of Bio-Pur® foam provides excellent air circulation, so sleepers never have to worry about overheating. Plus, BioPur® offers gentle pressure-relief without creating the “stuck” feeling associated with traditional memory foam.

Bio-Core® is quite sturdy so it prevents sagging and reinforces the whole structure of the AS1 mattress. Due to the durability of Bio-Core, you can expect this bed to last. And if it doesn’t— you’re protected by a lengthy 20-year warranty.

Amerisleep’s 20-year warranty is divided in half— for the first 10 years, Amerisleep will replace or repair the mattress at no extra cost to the customer. Should a repair or replacement be requested during the last 10 years, Amerisleep will replace the mattress for 50% of the original cost. Customers will also need to pay transportation and shipping costs on top of the prorated charge.

Defects covered under the warranty include sagging greater than 0.75 inches and faulty manufacturer defects not caused by customer misuse.

With Amerisleep’s 100-night sleep trial, customers can rest easy with the ability to try the AS1 within the comfort of their own homes. It takes 30 days for the body to adjust to a new bed, so Amerisleep recommends customers try the mattress for at least that long. If, for any reason, a customer is not satisfied, Amerisleep will work with them to process a refund.

  • Two types of steel coils maximize pressure relief and zoned support
  • Wool layer regulates heat while also being a natural flame barrier
  • Hand-tufted cotton rosettes prevent wear and secure the mattress layers
Recommended for...
  • Back and stomach sleepers
  • People with back pain
  • Sustainable shoppers

For a firmer bed made from natural materials, check out the JoyBed LXP. This hybrid mattress features organic and sustainable fibers over two types of pocketed coils to provide ample support and gentle cushioning. At 12 inches this, the medium-firm JoyBed LXP is a great choice for people with back pain, back sleepers, and stomach sleepers.

The JoyBed LXP’s cover is made from GOTS organic certified cotton. This jacquard fabric features hand-tufted rosettes to secure the mattress layers together. The rosettes are aesthetically pleasing while also helping the mattress last longer. Cotton itself is durable as well, further helping the mattress last.

The top layer of the mattress is an all-natural flame barrier made from potato plant fibers. It also adds a gentle cushion to the mattress to soothe pressure points.

Next are two layers of plush cotton designed to contour under the body’s curves. Cotton is also a crisp, breathable material, so it wicks away warm air to prevent you from overheating. Beneath the soft cotton is a thin wool layer. Not only is wool another natural flame retardant, but it regulates the mattress’s temperature. After that are another two layers of cotton, only this time they’re firm and provide extra support.

Finally comes a layer of nano coils, tiny steel coils which respond well to your movements. They relieve pressure, isolate motion, and keep your body lifted. At the bottom of the mattress are regular pocketed coils built to support the spine. The coils provide targeted support to promote healthy spinal alignment. They’re soft around the hips and shoulders and firm against the back.

The JoyBed LXP includes a 120-night sleep trial and a 10-year warranty. It also ships for free.

  • Latex has a natural firm feel and contours for pressure relief while keeping a sleeper "on top" of the bed.
  • Organic cotton cover moves heat and moisture away from a person, helped by wool batting.
  • Mattress made with organic wool and cotton, natural latex, and upcycled steel coils.
Recommended for...
  • Shoppers who want a firm mattress that's natural and sustainably produced.
  • Sleepers more interested in a latex mattress than a memory foam bed.

The Avocado mattress is a high-quality latex mattress. It stands at 11 inches tall with two 2-inch layers of Dunlop latex and 8 inches of tempered steel pocket coils. It’s covered in a 100% organic cotton cover.

Dunlop latex is similar to memory foam in its body-contouring properties, but is more responsive with a firmer feel. This latex mattress aligns the spine, isolates motion, and offers good edge support. The cotton cover uses New Zealand wool as a natural fire barrier and wicks away moisture. Because of its all-natural materials, the Avocado mattress does come with a higher price tag.

From years 1 through 11, customers can expect a non-prorated warranty— Avocado covers the cost of repairs or a replacement. After the 11th year, customers are charged a prorated amount for any repairs or replacements, which increases each year.

The 365-night sleep trial starts the day you receive your Avocado mattress. If unsatisfied, customers can contact the company and arrange for the mattress to be picked up and donated to a local charity. Once Avocado confirms the pick-up, they will issue a full refund.

It’s constructed with 1 inch of graphite-gel infused memory foam, 2 inches of responsive transitional poly-foam, 5 inches of high-density support foam, and 2 inches of adaptive poly-foam. The polyester cover includes FDA-determined Celliant® technology.

The firm foam support provides excellent spinal alignment by preventing the hips from sinking into the bed, reducing aches and pains. The Bear is a comfortable mattress for lower back pain relief because it keeps your spine aligned and relieves pressure in your back, hips, and shoulders.

Bear covers sagging greater than 1 inch and will cover repair or replacement costs. Customers are responsible for handling and transportation fees.

Bear requires that customers keep the Bear mattress for 30 days to allow time for the body to adjust to the new bed before they process any returns. If, after at least 30 days, a customer is not satisfied, Bear will schedule a time to pick up the mattress and donate it to a local charity.

This all-foam mattress comes in three different firmness options, but for this article, we focused on the firm option. The Novosbed lightly contours the body without causing it to sink down. Back and stomach sleepers receive needed pressure relief without feeling smothered. The supportive poly-foam base evenly distributes weight and isolates motion.

Once it arrives, the Novosbed must be unpacked within 2 weeks, otherwise, any damage caused from not unpacking it within the allotted time will void the warranty. Novosbed covers indents greater than 1 inch within the first 10 years and indents greater than 2 inches within the last 5 years of the warranty.

Novosbed requires its customers to keep the mattress for 60 days before they’ll issue any returns. If customers feel the mattress is too soft or too firm, after 30 days they can request a Comfort+ firmness adjustment kit for free. If still not satisfied after 60 days, Novosbed will arrange to pick up the mattress for a full refund.

  • Mattress's interwoven polyethylene resin fibers encourage airflow throughout the mattress.
  • Mattress is machine washable, making it simple for a owner to keep it clean.
  • The bed's feel balances firmness with a floating sensation.
Recommended for...
  • Sleepers who want a firm mattress that isn't a traditional foam or innerspring mattress.
  • Shoppers interested in the convenience of white glove delivery.

The Airweave mattress stands at 8.5 inches thick with two layers of 4 inch airweave polyethylene resin fibers. It comes encased in a removable, machine-washable cotton-poly cover that adds another 0.5 inch to the top of the mattress.

The exclusive polyethylene resin material is specifically designed for optimal airflow— the interwoven, open fibers allows air to easily pass through the mattress. Altogether, the Airweave mattress feels firmer than a traditional innerspring bed. Customers feel like they’re floating on top of the mattress instead of sinking into it.

This unique mattress is made in Japan and shipped via freight overseas— different than vacuum-packed, bed-in-a-box mattresses. Customers can pay an additional $40 for White Glove Delivery, though it doesn’t include old mattress removal.

The Airweave mattress cover also has the added bonus of being completely washable. Simply remove it and toss in the washing machine, then rinse the airfiber with water to remove any stains or spills.

The warranty includes sagging greater than 1 inch, any physical flaw that could cause the airfoam to split or crack, and any manufacturing defects. Airweave will replace a defective mattress with a new model, but they can also replace it with a different model— customers will need to pay the difference. However, the warranty doesn’t renew with the new mattress, but continues from the original mattress purchase date.

Airweave offers customers a 100-night sleep trial to properly try out their mattress. They only ask that customers keep the mattress for at least 30 days before they’ll issue a warranty. If customers are not completely satisfied, Airweave will issue a full refund.

Benefits of a Firm Mattress

A firm mattress can provide a variety of different benefits— extra support, cooler sleep, and spinal alignment to name a few. These benefits help sleepers improve not only their quality of sleep, but also their health.

Spinal Alignment

A firm sleep surface helps to align the spine and prevent both back and hip pains. Improper alignment can cause muscle strain and discomfort in the morning.

Extra Support

For those who suffer from shoulder, neck, hip, or other joint pain, a firm mattress gives more support and stability to the body, depending on an individual’s preferred sleep position. We recommend consulting with your doctor first before purchasing a firm mattress.

Even Weight Distribution

Firm mattresses are less likely to sag and evenly distribute the user’s weight across the sleep surface. Even weight distribution also helps position the spine in neutral alignment, further reducing the risk of pain.

Sleep Cooler

Firm beds make for great cooling mattresses.It’s easier to sleep on top of a firm mattress because they have very little give; this increases airflow and reduces the risk of heat retention.

Edge Support

A firm mattress is ideal for those who prefer sleeping on the edge of the bed or those worried about rolling off the bed. Good edge support prevents sleepers from slipping off the bed at night, and is also supportive when sitting on the edge of the mattress.

Less Sagging

Softer mattresses conform more closely to the body and run a higher risk of sagging. A firmer mattress is less likely to sag quickly under lots of weight.

Who Needs a Firm Mattress?

While it’s true firm mattresses typically last longer than softer mattresses, they may not be the right choice for everyone. Those who benefit the most from a firm mattress include stomach and back sleepers, hot sleepers, heavy sleepers, and those with back pain.

Stomach Sleepers

Stomach sleepers need more support in their hips— less support causes the hips to sink into the mattress resulting in improper spinal alignment and back strain. Firm mattresses keep the spine aligned and prevents misalignment.

Back Sleepers

Unlike stomach sleepers, back sleepers prefer a slight sinking below their hips. This helps support the natural “S” curvature of the spine. A medium firm mattress is best for back sleepers since it allows a small amount of sinking in the hip area, but still supports the back.

Hot Sleepers

For those who sleep hot, a firm mattress might be the best option. Rather than spend money on mattress pads with cooling technology, sleepers resting on top of a firm mattress are exposed to more air than they would be if they were sunken down in the bed. Firm mattresses are also less likely to retain heat because there’s less body inside the bed.

Heavy Sleepers

Soft and even some medium mattress models may not offer the support that a heavier individual, weighing 230lbs. or more needs. Those types of beds end up sagging, causing discomfort. A firm mattress offers the comfort and support heavy sleepers need for a good night’s sleep.

Those with Back Pain

Those who suffer from back pain may find relief in a firm mattress. A firm mattress aligns the spine and reduces back pain. A medium-firm to firm feel are good choices for back pain sufferers.

Who Should Avoid a Firm Mattress?

Firm mattresses aren’t comfortable for everyone— your preferred firmness level depends on your personal preferences, like sleep position, body type, and possible medical conditions.

Side Sleepers

Unlike stomach and back sleepers, side sleepers need a more plush surface for pressure relief in the shoulders and hips. While firm mattresses do offer some pressure relief, it may create more pressure points for side sleepers because of their lack of cushioning.

Lightweight Sleepers

Lightweight individuals don’t have enough weight to allow their bodies to sink into a firm or even a medium mattress, even with an added comfort layer. They need a more plush sleeping surface and would do better with a medium-soft to soft mattress.

Those with Arthritis, Rheumatism, or Scoliosis

A firm mattress could worsen some medical conditions like arthritis, rheumatism, or scoliosis. It depends on where in the body the medical condition or pain is centered. A firm sleep surface may create more pressure points and increase muscle tension and pain. If you’re looking for a comfortable mattress for arthritis pain relief, choose something conforming, responsive, and motion isolating.

What to Look For in a Firm Mattress

When on the hunt for the best firm mattress, pay attention to the types of materials— different materials serve different purposes and influence the overall feel of the mattress. Also, research available sleep trials, warranties, and return policies attached to each brand you look into.

Mattress Type

Each of these different types of mattresses provide their own perks. Customers can find a firm bed that can contain memory foam, latex, innersprings, or a hybrid with a combination of foam and innersprings.

Memory Foam Mattress

Memory foam mattresses contain a number of foam layers. The composition of these layers varies across brands, but a basic model uses memory foam as the top layer, followed by a polyurethane transitional layer and a high-density foam base. Memory foam is softer, retains heat, and conforms to the body. All foam is made from synthetic materials, and can range from soft to firm.

Latex Mattress

There are two types of latex— natural and synthetic. Natural latex comes from sap extracted from rubber trees, while synthetic latex is produced through a chemical process. Natural latex comes in two forms— Dunlop and Talalay. Dunlop latex is denser and more durable, while Talalay latex has a softer feel and sleeps cooler thanks to strategically placed ventilation holes.

Latex, especially natural latex, comes with a higher price tag. Similar to memory foam, it conforms to the body’s natural curves to relieve pressure, but it is more responsive. Latex mattresses are available in medium to firm options.

Innerspring Mattress

Innersprings contain steel coils with a thin comfort top layer. Innersprings are the traditional mattress many people grew up with. Firmer than memory foam, innersprings offer great air circulation but provide less pressure relief due to the coils. Innerspring mattresses are one of the most affordable options on the market.

Hybrid Mattress

Hybrids offer the best of both worlds— body contouring memory foam combined with the firm support of innersprings. Memory foam or latex act as a thick comfort layer with pocket coils for support. A true hybrid mattress must contain foam and coils. Hybrids offer good support and are available in a variety of firmness options.

Sleep Trials, Warranties, and Return Policies

Perks like sleep trials, warranties, and return policies are excellent ways to assure customers they’ve made the right choice. Many customers prefer to try a mattress out in their own home, rather than face the pressure of a salesman at a traditional brick-and-mortar store. Warranties and return policies act as further assurances to protect the customer and their mattress investment.

Sleep Trial

A sleep trial refers to a trial period to test out a mattress most manufacturers offer their customers with a purchase. Sleep trials are a convenient, no-hassle way of trying out a mattress within the comfort of your own home. Sleep trials should last 30 nights to allow for an adjustment period— most mattresses include a 100-night trial.


A brand new mattress should always have some type of warranty attached. Avoid purchasing a mattress that doesn’t have one. Warranties protect both the customer and the manufacturer. Always read the fine print before buying to know what to expect of the company and what the company expects of you.

Return Policy

In addition to the warranty, a return policy is another feature that should come with the purchase of a mattress. Return policies are easily confused with sleep trials— after all, they both let you try out a mattress, and if not satisfied, you can return it. The difference is some manufacturers don’t offer sleep trials and instead have a return policy. Return policies usually last 30 days, a shorter period of time compared to a sleep trial.


Now that you know what to look for in the best firm mattress, it’s time to start looking. If a firm mattress is right for you, there are several excellent choices out there. If your less concerned about finding a firm bed, look to our article on finding the best mattress of the year.

Frequently Asked Questions

Can a mattress be too firm?
Yes. When lying on your back, if you can easily slip your hand under the curve of your lower back, the mattress is too hard and needs more cushion. That “S” curve needs support for healthy spine alignment.

What is a bed-in-a-box mattress?
Bed-in-a-box mattresses are usually less expensive than other types. Companies send you a compressed mattress rolled up and packed in a box, allowing customers to easily set up their beds in their own home.

Is a firm mattress good for chronic pain?
If you suffer from chronic pain, it might be a good idea to consult your doctor before purchasing a mattress. A firm mattress may worsen some medical conditions and increase pain, depending on what area of the body the pain is originating from.
