Sleep Advisor Testing Methodology
At Sleep Advisor, our mattress reviews are based on findings from in-person tests that allow our team to have a genuine understanding of how the mattress feels and performs.
In the image, you can see our lead product tester, Julia Forbes, looking at features that are valuable to consumers with fibromyalgia, such as pressure relief and cooling.
What We Want to See in a Bed for Fibromyalgia
Soothing Pressure Relief
A mattress that cradles you can help take pressure off of sensitive joints and other areas that may be affected by fibromyalgia symptoms. You don’t want too much sink, but just enough for comfort.
Temperature Regulation
Some people with fibromyalgia experience temperature sensitivity, so a bed that runs reliably cool and maintains a stable, comfortable temperature is ideal. If you sleep hot or find that you wake up due to shifts in temperature, be mindful of the cooling elements in each mattress below.
Supportive Base
Even in softer mattresses with lots of pressure relief, a supportive base is a must. You don’t want your spine dipping out of alignment due to uneven or poor support, as this could cause back pain or exacerbate aches you’re already experiencing.
The Top 7 Beds for Fibromyalgia, Reviewed
Helix Dawn – Editor’s Pick
The Advisor Says: Helix’s firmest mattress certainly lives up to the hype. We recommend this bed to firm mattress fans (stomach or back sleepers, we’re looking at you) who are looking for a bed that prioritizes support.
Why the Helix Dawn Earned Best Mattress for Fibromyalgia Overall
The Helix Dawn represents a good compromise between pleasant-feeling foams and a sturdy, supportive construction. Both of these are essential for maintaining the type of well-supported spinal alignment that helps stave off pain and discomfort from fibromyalgia.
In our testing this bed also excelled in cooling. We used a thermal gun to record the Dawn’s surface temperature before and after lying on it for five minutes, and the mattress’s temperature only rose by about 5 degrees. We even repeated the test to make sure of this and got the same result. The Dawn’s innerspring coils help with breathability and also give it plenty of bounce, which should be pleasant for combination sleepers. This mattress is best for those who like a firmer, “on top” feeling, as well as those who sleep on their stomach or back.
Nectar – Best Memory Foam Mattress for Fibromyalgia
The Advisor Says: We believe that Nectar offers a quality bed backed up by generous policies, and for under $1,000 for a queen (after discounts). If you’re looking for a firmer foam mattress on a budget, the Nectar Classic has you covered.
Why the Nectar Earned Best Memory Foam Mattress for Fibromyalgia
Quality memory foam can do wonders for fibromyalgia symptoms, as it cradles sensitive joints. It also creates a comfortable surface and prevents too much motion transfer across the bed. The Nectar is an all-foam mattress that capitalizes on the benefits of this cozy material—I felt delightfully cushioned by the foam during testing.
What’s more, the Nectar’s straightforward design comes at a very affordable price, with impressive policies that make returns easy. Because the signs of fibromyalgia can vary so much from person to person, there’s no guarantee that a given bed will provide relief. Nectar’s 365-night sleep trial gives you a full year to decide if it’s the right mattress for you.
WinkBed – Best Mattress for Back Pain with Fibromyalgia
The Advisor Says: Our testers often compare the WinkBed to a luxury hotel mattress, which is no surprise given its handcrafted touches and elegant hybrid design. It’s also one of the most customizable beds out there, with a firmness level for every body type.
Why the WinkBed Earned Best Mattress for Back Pain with Fibromyalgia
Given its supportive hybrid construction and specialized lower-back support, the WinkBed is a natural fit for people with fibromyalgia and back pain. It cradles you on its surface, with enough gentleness for fibromyalgia-related aches and enough support to keep your body aligned.
During testing, I could feel the zoned coils and the bed’s LumbarLayer™ filling in the space beneath my lower back. The lumbar region is especially vulnerable to back pain, so I give the WInkBed extra points for how much lift I felt there.
Brooklyn Bedding CopperFlex – Best Cheap Mattress for Fibromyalgia
The Advisor Says: For the price, the Brooklyn Bedding CopperFlex is a bit of a steal. You can snag a California King for less than $1,000 (and that’s before discounts). Be warned that it’s quite firm, and probably best suited to back sleepers. Side and stomach sleepers will feel a pronounced lack of pressure relief.
Why the Brooklyn Bedding CopperFlex Earned Best Cheap Mattress for Fibromyalgia
Finding a bed that helps to offset your fibromyalgia symptoms can be difficult if you’re also on a budget. If you don’t want your mattress to be low-quality, but you can’t afford to drop more than $1,000, let me introduce you to the Brooklyn Bedding CopperFlex. This mattress comes in both foam and hybrid options, both within this price range. The foam version, however, costs only $665 for a queen, and that’s before sales and coupons.
Regardless of which construction you choose, the CopperFlex provides a cool, pressure-reliving surface with the support to back it up. It has a firmer feel that’s perhaps better suited to those who sleep on their stomach and back than those who sleep on their side.
Bear Star Hybrid – Best Mattress for Back Sleepers with Fibromyalgia
The Advisor Says: The Bear Star Hybrid touts an enviable medium-firm feel that should appeal to a swath of mattress shoppers, including couples with different preferences looking to “compromise.” We gave this hybrid perfect scores in pressure relief, support, and motion transfer.
Why the Bear Star Hybrid Earned Best Mattress for Back Sleepers with Fibromyalgia
Back sleepers with fibromyalgia likely want a mattress that’s firm enough to adequately align their spine but cushiony enough to help with soreness, fatigue, and overheating.
The Bear Star Hybrid ranks at a 6 out of 10 on our firmness scale (with 10 being hard as a rock), so it’s medium-firm but not too floor-like. Its first layer of gel foam assists with soothing pressure relief and combines forces with a specialized cover to keep the bed cool.
Nolah Signature – Best Mattress for Side Sleepers with Fibromyalgia
The Advisor Says: We recommend the Nolah Signature for sleepers looking for a foam bed that has a soft but accommodating firmness. It also runs cooler than most foam beds, and has enough pressure relief to cradle sensitive joints.
Why the Nolah Signature Earned Best Mattress for Side Sleepers with Fibromyalgia
For side sleepers with Fibromyalgia, a mattress that excels at pressure relief without lacking support will be key. Enter the Nolah Signature. This all-foam mattress delivers pressure relief through its proprietary AirFoam™ while the dense foam core helps keep you lifted.
This is complemented by an overall medium-firm feel, which means it won’t be too hard for dedicated side sleepers.
Saatva Classic – Best Cooling Mattress for Fibromyalgia
The Advisor Says: The Saatva Classic is the gold standard for lower-back support, strong edges, and customizable luxury. It’s not the softest or most motion-isolating bed out there, but it’s a dependable, bouncy hybrid that consistently impresses our testers with its two coil units.
Why the Saatva Classic Earned Best Cooling Mattress for Fibromyalgia
Temperature sensitivity can be a symptom of fibromyalgia, and trying to get to sleep while you’re overheated can compound the fatigue that also often comes with the condition. So, if you want enough pressure relief and support from your bed to soothe aches and pains, finding a mattress that stays cool enough can be a challenge.
The Saatva is a luxury mattress that manages to ease pressure points and potential pain while also keeping cool thanks to its design that include not one but two innerspring units.
What to Look for in a Mattress for Fibromyalgia
Considering that a fibromyalgia diagnosis is often accompanied by full-body pain, as well as sleep issues and fatigue, a mattress can be an essential tool in helping you find comfort.1 While your personal preferences for a mattress are a top priority, when you’re also dealing with fibromyalgia, there are certain features you should look for when shopping for a new bed.
Mattresses that provide pressure relief while supporting your spine may help alleviate some of the uncomfortable symptoms of this disease. Furthermore, it will be paramount to look for mattresses made from quality materials that can enhance your overall well-being.
Advice from a Medical Expert
We reached out to Dr. Raj Dasgupta, who has over 20 years of experience in the medical field, to see his thoughts on how a mattress can help with fibromyalgia.
“A mattress can make fibromyalgia symptoms worse if it’s not supportive and doesn’t relieve pressure points, leading to more pain and restless nights. On the flip side, a mattress that offers good support, relieves pressure, and feels just right can help ease fibromyalgia symptoms by reducing pain and improving sleep quality, so you wake up feeling more rested.”
Type of Mattress
Innerspring Mattresses
Innerspring mattresses can lack a substantial enough comfort layer to help with the discomfort caused by fibromyalgia. They offer less contouring than foam options, and their “push-back” can be quite pronounced, which may aggravate your symptoms.
If you love the bounce and feel of this mattress type, one of the best things you can do is to combine an innerspring unit with a more cushioning material, such as memory foam or latex, which is where hybrids come in handy.
Hybrid Mattresses
A hybrid mattress may help alleviate fibromyalgia symptoms. The comfort layers can provide the right amount of pressure relief to help with the pain of fibromyalgia, while the coil unit encourages proper support and alignment.
The best hybrid mattresses combine foam and springs to convey the benefits of both innerspring and foam beds while mitigating their shortcomings.
As hybrids can be constructed from a nearly limitless blend of materials, it’s important to investigate the layers of any hybrid bed you’re considering.
Memory Foam Mattresses
High-quality memory foam can be a beneficial material for offsetting fibromyalgia symptoms. It’s designed to provide comprehensive contouring, optimal support, and palpable pressure relief.
Memory foam encourages healthy spinal alignment, and many kinds are innately hypoallergenic. Couples can also enjoy the fact that this foam reliably limits motion transfer.
Memory foam mattresses are usually quite versatile — they can fit most adjustable frames and are usually easier to transport than beds that contain springs.

Latex Mattresses
Latex mattresses are both pressure-relieving and responsive. This mix of qualities helps to prevent body aches while simultaneously keeping you from feeling “stuck” in the bed.
Latex beds are also known to be extremely durable, hypoallergenic, and better at temperature regulation than some memory foam models. However, keep in mind that some high-end latex beds — typically ones made with primarily natural or organic materials — are quite costly.
Other Considerations When Shopping for a Mattress for Fibromyalgia
Support
A supportive mattress is helpful in general, but it’s especially important for those with fibromyalgia. A good way to help you know that the mattress is properly supportive is if it can keep your body on a level plane. This means that one or more parts of the spine are not going to be located higher than others.
Consistent support is going to help keep your spine aligned. If your bed is sagging, this may just lead to more pain, but if your bed supports you properly, your spine should be just as it is when you stand up straight.
Sleeping Position
If you sleep on your back, a medium-firm mattress that can relieve pressure and support your spine could be optimal. Side sleeping may dissipate some of the tension that builds up in your body, but you’ll want to make sure you have a plush mattress that softly cradles around your shoulders and hips.
Although some sleepers may find some relief by sleeping on their stomachs, this can be a tricky position. If your bed is not supportive enough, your hips may sink too far down, which could leave your spine in a compromising position that may cause more pain.
Weight/Body Type of Sleepers
A person’s weight can alter how hard or soft a bed feels and because of this, it should be a consideration for those with fibromyalgia. It may also mean that they decide on a different kind of bed than those of similar weight who don’t have this condition. Given that many with this condition have musculoskeletal pain, a bed that comforts and contours the parts of the body that come into contact with the mattress could be helpful.
Typically, the more people weigh, the firmer their bed should be, but this may need to be tweaked some for those for whom a firm mattress may create more pain and tension.
Firmness
Mattress firmness is an important factor to consider when it comes to relieving pain. The last thing you’d want is to experience even more pain while you are sleeping on a bed that turned out to be too firm or too soft. The ideal firmness when it comes to pressure and pain relief tends to be medium to medium-firm for most, although firmness is subjective.
A general rule of thumb (though everyone should follow what works best for them individually) is that unless you are a side sleeper, you will want to check out a medium-firm mattress, though some stomach sleepers may want a firm mattress specifically. If you’re a side sleeper, however, you may want to go for something softer. These particular beds would provide your body with a chance to sink a little more in order to promote proper spinal health and alignment.
Cooling
Some people with fibromyalgia report that their symptoms are intensified by the cold.2 If this is the case for you, a cooling mattress may not be necessary. In this case, you might be fine with a standard memory foam option that doesn’t come with added cooling features.
However, others who would sleep better on a cooler bed space should look at innerspring, hybrid, and latex mattresses as these are all great for cooling.
Additionally, memory foam with infused cooling gel or other means to regulate temperature can also be an excellent option given how well this foam cradles the curves of the body.
Motion Isolation
If you’ve ever been woken by a partner’s or pet’s restlessness, you were likely sleeping on a bed with poor motion isolation. Beds that don’t keep the motion created by one co-sleeper contained to their side of the bed can be particularly problematic for those with fibromyalgia as unexpected jolts may exacerbate the pain that they may be experiencing.
Memory foam is a material that tends to respond slowly and absorb motion well, and those with fibromyalgia may want to explore this option, especially if they sleep with another.
Sex
Women are much more likely to develop fibromyalgia than men.2 As such, much of the research about fibromyalgia and sexual intercourse has to do with women. It has been shown that women with fibromyalgia have decreased sexual desire and report pain associated with intimacy.3
However, for those couples who are able to engage in intimacy, it can help to have a bed that can help foster easier movement and repositioning. In this case, beds that are responsive and bouncy, including innerspring, hybrid, and latex models, can be beneficial for sex.

Pressure Relief
A mattress that’s not right for you can hit pressure points that are already quite painful from fibromyalgia. This can make it nearly impossible to fully recharge your body and feel restored when you wake up.
If you have a quality mattress made of memory foam or latex, it should contour your body and provide you with additional support that you actually need. This is important, and it helps deliver pressure relief. Of course, other mattress types are also capable of doing so – it’s about finding your right fit for the best rest.
The thing you should avoid is getting a bed that will aggravate the pressure points because this can cause even more pain and sleepless nights.

Edge Support
Edge support is crucial for many people, especially those who like to spread across the entire bed. Couples and single individuals who like to use the entire bed can benefit from strong edges that won’t collapse under the weight. However, not every bed has good edge support.
Mattresses with a reinforced perimeter typically do a better job supporting the edges than beds without any additional reinforcement. Hybrids and innerspring mattresses sometimes have additional higher-gauge coils in this area, helping the edges to maintain their shape. Memory foam beds may have higher-density foam along the perimeter.

Ease of Movement
People with fibromyalgia have a higher pain sensitivity and may find it more difficult to move around on a mattress.4 This is especially the case if they sleep on a bed that doesn’t fit them in terms of firmness.
A mattress that’s too soft may allow too much sinkage, making you slip inside the comfort layer. This can make it difficult to move around and get in and out of bed. For this reason, many people with fibromyalgia may prefer a medium to medium-firm bed that allows a bit of contouring for pressure relief but without trapping you inside the comfort layer.
Budget
Mattresses can be a big investment, and it is advisable to have a budget before you start shopping. This will allow you to narrow down your choices to see what’s in your price range. Those with fibromyalgia will want to look for a bed with quality materials, and while this may mean a slightly higher price point, if it can help you rest better, then it could be worth it.

What Causes Fibromyalgia?
A variety of circumstances can cause fibromyalgia. These can include a car accident, psychological distress, an infection, or genetics.1 Women and those with a family history of this condition are more at risk of developing fibromyalgia.1 Additionally, having osteoarthritis, rheumatoid arthritis or lupus can increase your chances of developing fibromyalgia.1
How Can a Mattress Help with Fibromyalgia?
The pain caused by fibromyalgia can make sleep difficult. Having a mattress that provides pressure relief may be able to ease some of the discomfort caused by this condition. Additionally, finding the right mattress for your weight and sleep type can provide good support to your spine, which can also help alleviate pain.
What Is the Best Sleeping Position for Fibromyalgia?
Back Sleeping
When you have fibromyalgia but are a back sleeper, you can try to sleep with your knees raised. This could help alleviate the pain that stems from your lower back or pelvis.
There are several ways you can do this. One way is to place a pillow, such as a wedge pillow, under your knees. The other option could be to use an adjustable base that can raise your knees for you.
Explore our picks for the best mattress for back sleepers.
Side Sleeping
Fibromyalgia is a very painful condition. It causes pain in tender spots throughout your entire body. However, sleeping on the side could be a temporary remedy that would enable you to sleep better, depending on where you’re experiencing the most pain.
The fetal position could help reduce tension throughout your body. That being said, be sure your bed provides great pressure relief so you don’t exacerbate any discomfort on the hip and shoulder.

Combination Sleeping
People with fibromyalgia may find themselves switching positions throughout the night because that is their natural sleeping pattern or because their symptoms make them restless. If you’re a combination sleeper, it’s a good idea to ensure whichever bed you choose accommodates multiple positions and fosters easier movement.

Stomach Sleeping
People with fibromyalgia may find relief when sleeping on their stomachs. However, caution is advised with this position, primarily due to potential stress on the neck. You’ll want a flat pillow to minimize neck strain.
Additionally, ensure your mattress provides adequate support to prevent your hips from sinking too deeply, as this can lead to excessive lower back curvature and exacerbate pain. A supportive mattress, as well as a firm mattress topper, can help maintain proper alignment.

Tips for Getting Better Sleep with Fibromyalgia
Exercise
According to Harvard University, exercise helps, even though you might find it hard and challenging.5 It should help you feel a lot better and more energized. Certain activities don’t require that much effort, such as walking, stretching, and even swimming. Even if it is only for a few short cycles at a time – it’s best to consider it. Of course, you should consult with a doctor to see what exercises are appropriate.

Best Mattress for Fibromyalgia FAQs
Is memory foam good for fibromyalgia?
Memory foam can be good for fibromyalgia as it allows contouring and pressure relief to help ease the tension and pain you may feel in your joints. However, you should always consider mattress firmness because even memory foam can be too firm to allow any sinkage. Look for medium to medium-firm memory foam that has a slow response and allows gentle contouring so that it doesn’t create any pressure buildup.
What mattress firmness is best for fibromyalgia?
Most people might benefit from a medium to medium-firm bed, depending on their body weight and preferred sleeping position. In other words, some may do better with a softer or firmer bed. For example, if you’re a side sleeper, particularly weighing under 130 pounds, you may need a softer bed to get better pressure relief. Stomach sleepers are likely to do better with a firmer bed, especially if they weigh over 230 pounds.
Will a memory foam bed topper help with fibromyalgia?
Even though a memory foam mattress topper is capable of helping you out with fibromyalgia, there are a lot of variables to consider. Right off the bat, you need to make sure that your mattress underneath it is not completely sagged. If that’s the case, replacing it should be a priority. In general, though, a mattress topper could go a long way in helping you out with this challenging condition.
Is restless legs syndrome related to fibromyalgia?
Restless legs syndrome (RLS) is not directly related to fibromyalgia, but there is some sort of a connection between them.8 The truth is that people living with fibromyalgia are more prone to restless leg syndrome as well. If you experience this issue, the very first thing that you ought to do is to go ahead and call your doctor to see if there are any techniques that can help, as it’s definitely capable of keeping you up at night.
