Foam vs spring mattress for back pain

Neither type is the clear winner for everyone with back pain. Choose based on how well the mattress supports your body and spreads pressure, not just whether it contains foam or springs.

One study followed people with long-lasting low-back pain for a month. A body-conforming foam mattress and a waterbed seemed to do better than a hard futon for back symptoms, daily function, and sleep. But the differences were small. The study did not compare foam with springs.

Spring mattresses generally felt bouncier in one range of mattress tests, but neither foam nor springs had an overall advantage in those tests. Back pain has many possible causes, so changing your mattress may not address yours.

Consider firmness and support alongside type rather than assuming one matters most. Firmness is how soft or firm a bed feels. Support is separate: a soft bed can be supportive, and a firm one can lack support.

Medium-firm is a useful starting point, not a rule for everyone. One trial included 313 adults with long-lasting low-back pain without a specific cause who reported pain in bed or on rising. At 90 days, those assigned medium-firm mattresses had better results than those assigned firm mattresses. They had better results for pain in bed, pain on rising, and disability. A review of studies found inconsistent results about which mattress was best for low-back pain.

Another review looked at 24 articles on controlled trials. In that review, a mattress described as medium-firm and custom-inflated, or self-adjusted, was best for sleep comfort, sleep quality, and spinal alignment. A separate survey included 268 people with low-back pain. Those on very hard mattresses had the poorest sleep quality. There was no sleep-quality difference between those using medium-firm and firm mattresses.

A hybrid is an option, but it is not necessarily better for your back pain than foam or springs. A hybrid has a coil support core under a comfort system that can include foam, latex, or other materials.

It combines foam's body-hugging feel with the bounce and breathability associated with springs. Its performance varies with its materials and construction, so try the individual mattress rather than relying on the hybrid label.

Match support to your body and sleep position. The same mattress is likely to feel softer to a heavier person and firmer to a lighter person.

For side sleepers, a mattress that is too firm can put pressure on the hips and shoulders. It can also push the spine out of alignment. A surface that is too soft can sag too much and lead to poor posture. As a starting point, suggested firmness ranges for side sleepers vary by weight.

For back pain made worse by walking and standing, side sleepers can try lying on their least painful side with hips and knees slightly bent and one or two pillows between their knees. Whatever your position, use pillows for support where the mattress does not support your body.

Check your alignment on your side. Ask someone to look at you or take a picture while you lie on your side. Your head, shoulders, spine, and hips should form a roughly straight line. Your head should not angle up or down, and your hips should not sink down.

Try different mattresses in a showroom, but remember that a few comfortable minutes may not predict a full night's sleep. Notice how you feel after sleeping on a different mattress at a hotel or a friend or relative's home.

Also check the mattress base. A more stable foundation or bunkie board may add support and make the bed feel firmer. A bunkie board is a flat support placed under a mattress. Check that the base is compatible with your mattress model.

Give your body time to adjust and check the return deadline before you buy. Adjusting to a new mattress can take around a month. Try sleeping on it for at least several weeks before starting a return, even if there is no required break-in period. Notice how you feel after sleeping on it.

Before ordering, check the trial length, any required break-in period, return conditions, and costs. Trials vary: the typical average is 90 to 120 nights, while some last 30 nights or a year or more.

For example, Leesa recommends at least 30 nights to break in its mattresses. It allows eligible returns from night 31 through night 365. Its 365-night trial applies to the first two mattress purchases per household and shipping/billing address.

An old or sagging mattress is not proof of what is causing your morning back pain. One owner reported that an innerspring mattress later sagged and caused back pain, but that report cannot establish the cause of another person's pain.

Check for sagging and whether your mattress still supports you. A mattress can become too worn to provide enough support. If it does, a topper is unlikely to do much to make it comfortable, and you may need a new mattress.

Check the mattress and its base. For example, Tempur-Pedic says its mattresses may sag when they lack a flat, solid surface that supports them adequately. You can also look for the permanent label showing the mattress's month and year of manufacture. Its age alone does not show whether it still supports you.

A topper can soften a firm mattress or add comfort and support. It may also improve pressure distribution and ease pressure on sore hips or shoulders, but it will not instantly cure back pain.

A topper is unlikely to improve an old, sagging mattress enough, and it will not fix the sag. If your mattress is too worn to support you, consider a new mattress instead. Topper construction and thickness affect the feel; thicker foam contours more closely than thinner foam.

Seek medical advice for back pain, rather than relying on a mattress change. Back pain usually improves within a few weeks, but it can last longer or return.

Make a doctor's appointment if your back pain:

• Has not improved after a few weeks of care at home.
• Stops you from doing daily activities.
• Worries you or is hard to cope with.
• Comes with weight loss you did not intend.
• Comes with a lump, swelling, or a change in the shape of your back.
• Does not improve with rest or is worse at night.
• Gets worse when you sneeze, cough, or have a bowel movement.
• Is in your upper back between your shoulders rather than your lower back.

Get urgent medical help if you have back pain and feel hot, cold, shivery, or generally unwell. Also get urgent help if severe back pain starts suddenly, or if your back pain gets worse quickly.

Get emergency care immediately if you have back pain and any of these signs:

• Pain, tingling, weakness, or numbness in both legs.
• Loss of feeling around your genitals or anus.
• Changes in your bladder or bowels, such as difficulty peeing, or peeing or pooing yourself.
• Changes in feeling during sex, trouble getting or keeping an erection, or being unable to orgasm.
• Chest pain.
• Back pain that started after a serious accident, such as a car accident.
