If you have low back pain from sleeping on an unsupportive mattress, you are not getting the rest you need to function your best each morning. Back pain in bed is a common issue. You can either keep waking up bleary-eyed and achy, or make some changes that lead to better, more energetic days.
If you are waking up with muscle pain or stiffness, your mattress may be the hidden culprit. Pain symptoms like a dull ache in your lower back, stiffness that fades after 10-15 minutes of movement, or frequent tossing and turning at night all suggest a connection between your mattress and back problems.
You might also notice you sleep better on hotel beds or other mattresses. If pain lessens away from home, your bed could be hurting your sleep health more than you realize.
As a fifth-generation mattress manufacturer and Chief Bedmaker at The Beloit Mattress Company, I have handcrafted mattresses at our Beloit, Wisconsin factory for decades. Back pain tied to a mattress is one of the most common problems I help customers solve, and this guide shares exactly what I tell them.
Key Takeaways
- Back pain that eases after 10-15 minutes of moving around in the morning is one of the clearest signs your mattress is the cause.
- A mattress that is too soft lets the spine sag out of alignment. A mattress that is too firm creates pressure points at the hips and shoulders.
- A new mattress can cause temporary back pain as your body adjusts. If pain lasts more than 3-4 weeks, the firmness or support level is likely wrong for your body.
- Always check sleep position and pillow placement before assuming the mattress is the only issue.
- A quality mattress topper can provide temporary relief but will not fix a mattress that has structurally failed.
- If back pain persists after adjusting sleep position, pillows, and foundation, consult a physician to rule out an underlying condition.
Can a Mattress Cause Back Pain?
Yes. A mattress can absolutely cause or worsen back pain. When a mattress fails to support the natural curvature of your spine, your muscles work harder to compensate throughout the night. That sustained tension leads to stiffness, soreness, and pain in the morning, particularly in the lower back.
A mattress that is too soft allows the heavier parts of your body (hips, lower back) to sink too far, pulling the spine out of alignment. A mattress that is too firm pushes against the hips and shoulders without contouring, creating pressure points. Either condition can cause or aggravate back pain over time.
The clearest sign that your mattress is causing your back pain is if the pain is worst in the morning and improves within 10-30 minutes of getting up and moving. That pattern points to a sleep surface issue, not a daytime activity or posture problem.
Common Causes of Back Pain in Bed
If your old mattress is no longer providing proper support, it may be the cause of your nightly discomfort. Back pain in bed is a common issue. If your back hurts after sleeping, particularly when you are getting into bed, do not ignore it. Back pain can be a symptom of an underlying problem like poor spinal alignment, spinal stenosis, or disc degeneration. I suggest assessing whether these common issues could be the culprit first:
Common Causes of Back Pain in Bed
| Cause | Explanation | Recommendations |
|---|---|---|
| Poor sleeping position | Positions that fail to keep the spine aligned, such as stomach sleeping or using too many pillows, strain the back muscles. Side sleeping with a twisted spine can also cause pain. | Sleep on your side with a pillow between your knees. Back sleepers: place a pillow under the knees. Avoid stomach sleeping. |
| Unsupportive mattress | A mattress too soft lets the spine sag out of alignment. One too firm creates pressure points. Either can cause or worsen back pain. | Choose a mattress that supports and contours your body. Consider a firm topper to improve an aging mattress. |
| Lack of lumbar support | Back sleepers need to maintain the natural curve of the lower spine. Sleeping without a pillow under the knees can cause the lumbar region to arch unnaturally. | Use a lumbar roll or rolled towel in the small of the back. Consider a mattress or topper with targeted lumbar support. |
| Underlying medical conditions | Fibromyalgia, arthritis, sciatica, and degenerative disc disease can all worsen nighttime back pain when lying down. | Seek medical advice if pain is severe, radiates to other areas, or is accompanied by numbness. Follow a personalized treatment plan. |
How to Tell if Your Bed Is Causing Your Back Pain
Your bed is likely the cause of your back pain if you notice any of the following signs:
- Pain is worst in the morning and eases within 10-30 minutes of getting up and moving
- You sleep noticeably better on other mattresses, such as in a hotel or guest room
- You can visibly see a dip, sag, or uneven surface in your mattress
- Your mattress is more than 7-10 years old and comfort has changed noticeably
- You wake up in the same painful position every night and feel like the bed is pulling you into a low spot
- You toss and turn regularly trying to get comfortable
If more than two or three of these apply to you, your mattress is a strong candidate for the cause. Start with the solutions below before assuming a more serious underlying condition.
Why Is My New Mattress Hurting My Back?
It is normal for a new mattress to cause some back discomfort during the first 2-4 weeks as your body adjusts from one sleep surface to another. Your muscles and spine have adapted to the feel of your old mattress, and a new one, even a better one, will feel unfamiliar at first.
However, if back pain on a new mattress persists beyond 4-6 weeks or feels significantly worse than before, the mattress firmness or support level may not match your body type and sleep position. Common causes of new mattress back pain include:
- Too firm for your sleep position: Side sleepers need more contouring at the hips and shoulders. A very firm new mattress can create pressure points if you sleep on your side.
- Too soft for your body weight: Heavier sleepers on a soft new mattress may sink too far, pulling the lower back out of a neutral position.
- Wrong foundation: A new mattress on an old or incompatible foundation, slatted base with gaps too wide, or a sagging box spring can make even a quality new mattress perform poorly from day one.
- Body adjustment period: Your muscles are re-learning how to rest. This typically improves on its own within a month.
If you are within your mattress trial or warranty period and pain does not improve after 4-6 weeks, contact the retailer. Most quality mattress companies, including ours, offer comfort assurance programs specifically for this reason.
Why Is Back Pain Worse When Lying Down?
When you lie down, your spine and spinal discs experience different pressure levels than when standing. If your bed lacks proper support, pre-existing conditions like muscle strain or shoulder pain may feel intensified, leading to a sore back in the morning.
Most people who experience back pain have strained muscles. Poor posture during the day, sitting at a desk without proper support, or lounging on the couch in an unsupported position can cause specific muscles to contract over long periods. You may not notice it when you walk around. But those sensitive, strained muscles are agitated when your back hits an unsupportive bed. That added pressure on the affected area causes those muscles to hurt.
Mattress Firmness: Soft vs. Firm for Back Pain Relief
Soft Mattresses
Pros:
- Offers relief to lighter individuals and people with joint pain
- Reduces pressure on hips and shoulders
Cons:
- Can cause the lumbar spine to sag out of a neutral position
- Leads to poor sleep and worsened back pain over time
Firm Mattresses
Pros:
- Promotes a neutral spine position
- Supports the lumbar spine and reduces unnatural positional pressure
Cons:
- May worsen back problems like arthritis or scoliosis
- Takes time to adjust if switching from a softer bed
The best choice strikes the right balance, offering firmness for alignment but enough softness for pressure relief at the hips and shoulders.
Mattress Firmness: Soft vs. Firm for Back Pain Relief
If your mattress is too soft and your back hurts, the core problem is that your hips and lower back are sinking too far and pulling the spine out of alignment. Here is what to try before buying a new mattress:
- Add a firm mattress topper: A medium-firm to firm topper (latex or high-density foam) can add a supportive layer above the soft surface and help keep the spine more level.
- Add a bunkie board or plywood under the mattress: If the mattress is bottoming out or the foundation has too much give, a solid base beneath the mattress can reduce sink.
- Check the foundation: A worn box spring or slatted base with wide gaps can make even a medium-firm mattress feel overly soft. Replace it before replacing the mattress.
- Change sleep position: Side sleepers on a soft mattress often sink the most at the hips. Placing a firm pillow between the knees can reduce the hip drop and take pressure off the lower back.
If pain persists despite these adjustments, the mattress has likely softened beyond the point where surface fixes help, and replacement is the better long-term answer.
Why Mattress Material Matters for Back Pain
Material type impacts how well your mattress can support deep sleep and reduce muscle pain. Here is how different materials compare:
- Memory Foam: Conforms to body curves, keeps the spine in a neutral position, excellent for people with a herniated disc.
- Hybrid Mattress: Combines coils and foam for balanced support. A common type recommended by medical experts.
- Gel Mattresses: Help regulate temperature and support pressure points, promoting better sleep for hot sleepers.
- Innerspring: Traditional choice that varies in comfort depending on coil construction.
Choosing a material that supports your lumbar spine can significantly improve your overall sleep health.
Bed Killing Your Lower Back? 6 Solutions to Help Back Pain in Bed
Here are the tips I share most often to help relieve back pain in bed and get you the sleep you deserve.
1. Reduce Inflammation Through Diet and Exercise
Consuming anti-inflammatory foods and performing exercises for core strength can reduce discomfort. When your joints are inflamed from daily activity and eating habits, you will experience pain during the night. Try reducing refined bread and other carbohydrates, fried foods, sugary beverages, and red meat.
Instead, eat foods that fight inflammation: fruit, tomatoes, olive oil, leafy greens, almonds, and fatty fish like salmon and tuna. You may be surprised at how much morning back pain improves after just a couple of weeks of eating well. Yoga several times weekly can also improve flexibility and reduce tension in the muscles that support your back.
2. Do Not Sleep on a Mattress That Is Too Soft or Too Hard
A mattress that is too soft will cause your back or hips to sag and your spine to fall out of alignment, leading to significant pain. A mattress that is too firm will put too much pressure on your joints, especially if you sleep on your side or your back.
To reduce back pain in bed, you need a quality mattress that offers support but also contours your body to relieve pressure. There is no single best mattress for all back pain. Your body type, sleep position, and comfort preferences all factor into the right choice. Be sure you are investing in a mattress made from materials suited to your unique needs.
3. Place an Adjustable Base Under Your Mattress
Sleeping at an incline can take pressure off your spine, as can raising the foot of the bed. An adjustable base allows you to raise and lower your bed until you find the right position for your lower back. Adjustable beds can also help with snoring and improve overall sleep quality.
4. Use a Pillow to Keep Your Spine in Alignment
Waking up with lower back pain often means your spine was rotated throughout the night. Try placing a pillow between your knees if you sleep on your side. If you sleep on your back, place a pillow behind your knees. And if you sleep on your stomach, try placing a pillow under your hips and lower abdomen with a thin pillow under your head.
The right pillow can also help reduce neck pain. See our guide on how to choose the right pillow for your sleep style.
5. Try a Mattress Topper for Pressure Relief
If replacing your mattress is not an option yet, a high-quality mattress topper can offer an affordable solution to relieve back pain and improve sleep health. Toppers are designed to enhance the comfort and support of your existing mattress without the investment of buying a whole new bed.
Key features to look for when selecting a topper for back pain:
- Enough firmness to maintain a neutral spine position: A topper that is too soft can cause you to sink too deeply, placing the spine in an unnatural position. Look for a medium-firm or firmer topper.
- Good contouring to relieve pressure at hips and shoulders: A well-designed topper gently supports your body’s curves, reducing pressure points in sensitive areas.
- Sufficient thickness without losing alignment: Toppers in the 2-4 inch range typically provide the best balance of comfort and support.
Be sure you are using your mattress topper properly and that it is laid over the correct base. Shop our topper collection here.
6. Look into a Custom Mattress for Better Back Pain Relief
A custom mattress is built to your exact specifications and unique needs. It can fit almost any size, including spaces on RVs, boats, futons, and trucks. Custom mattresses can also be engineered to address specific back pain concerns: firmness level, lumbar support, pressure relief, and temperature regulation.
When It Is Time to Replace Your Mattress
Consider replacing your mattress if:
- Your back pain improves when sleeping elsewhere
- Your mattress is visibly sagging or uneven
- You consistently experience poor sleep despite other lifestyle changes
- Your mattress is over 7-10 years old and comfort has clearly changed
Upgrading to a mattress suited for your body type can drastically reduce back problems and help you achieve deeper, more restorative sleep. If you are not sure whether your mattress is the cause, see the checklist in the “How to Tell if Your Bed Is Causing Your Back Pain” section above.

Frequently Asked Questions About Back Pain in Bed
Can a mattress cause back pain?
Yes. A mattress that is too soft, too firm, or worn out can place the spine in an unsupported or misaligned position for hours at a time. That sustained strain leads to muscle tension, inflammation, and morning back pain. If your back pain is worst when you wake up and improves after moving around, the mattress is the most likely cause.
Why does my new mattress hurt my back?
A new mattress can cause temporary back discomfort during the first 2-4 weeks as your body adapts to the new sleep surface. If pain persists beyond 4-6 weeks, the mattress firmness may not match your body type or sleep position. Check the foundation underneath as well. A new mattress on an inadequate foundation will not perform correctly.
What mattress firmness is best for lower back pain?
Medium-firm is the most widely recommended firmness for lower back pain because it balances support and pressure relief. But the right choice depends on your sleep position and body type. Side sleepers often do better with a slightly softer surface. Back and stomach sleepers typically need more firmness to keep the lumbar spine from sagging.
How do I relieve back pain caused by my mattress?
Start by checking your sleep position and pillow placement. Then inspect the mattress for visible sagging or wear. If the foundation is weak or the mattress is old, address those first. A firm mattress topper can provide short-term relief if the mattress surface has worn down. For lasting relief, replacing an aging or unsupportive mattress is usually the most effective solution.
Is a firm or soft mattress better for lower back pain?
Neither extreme is ideal. A mattress that is too soft lets the hips and lower back sink out of alignment. A mattress that is too firm creates pressure points at the hips and shoulders. The best option for most people with lower back pain is a medium-firm mattress that keeps the spine level while providing enough cushioning for pressure relief.
How to tell if your mattress is causing your back pain?
Your mattress is likely the cause if your back pain is worst in the morning and improves within 30 minutes of getting up, you sleep better in other beds, you can see a sag or dip in the mattress surface, or your mattress is more than 7-10 years old. If two or more of these apply, the mattress is the most probable cause.
What should I do if my back hurts after sleeping on a new mattress?
Give it 2-4 weeks to allow your body to adjust. Check that the foundation underneath is compatible with the mattress. Adjust your sleep position and pillow placement. If pain has not improved after 4-6 weeks, contact the retailer. Most quality mattress companies including Beloit Mattress Company offer a comfort assurance program that allows you to adjust firmness or exchange the mattress during the trial period.
Why does my back hurt when I get into bed?
Back pain that starts when you lie down is often caused by pre-existing muscle strain being aggravated by an unsupportive sleep surface. When you stand or walk, those strained muscles are active and somewhat supported. When you lie on a soft or uneven mattress, the same muscles experience uneven pressure without the benefit of movement, which triggers pain.
