#1 in Sleep Product Research Millions Served Since 2008 Ratings > Mattresses and Bad Back Problems Unbiased Comparisons Based on 22,478 Owner Experiences Some mattresses perform significantly better than others in preventing / relieving pain, including back, hip and shoulder pain. Before discussing which are best, three interrelated terms are important to understand: support, conforming ability, and firmness. Support refers to how well a mattress keeps the sleeper's body on a flat and level plane. Owner experience data shows that support is a key factor in preventing and alleviating pain, especially back pain. Support can be undermined by excessive softness and excessive firmness – but it is most often undermined by sagging of the mattress. Sagging is the top complaint of mattress owners overall with at least 30% reporting a significant problem. Sagging occurs when part of a mattress, usually the middle, becomes compressed and lower than the rest.
Sagging often puts a person's spine into an unnatural position – especially for side and stomach sleepers. Consequently, mattress owner experience data shows a clear connection between sagging and pain, especially back pain. The greater the sagging depth the more likely it is that sagging will cause a person to have discomfort or pain in bed and possibly out of bed. * especially for side and / or stomach sleepers. It should be noted that despite the fact that back pain for many people may occur with less than 1.5 inches of sagging depth, many mattress warranties cover sagging only if it has a depth greater than 1.5 inches. Conforming ability refers to how well a mattress conforms or molds to the contours and curves of a person's body. A mattress has good conforming ability if all of one's body is supported equally by the mattress. A lack of conforming ability means there are gaps in support. The result can be that at least one part of the body – such as the lower back – is placed in an unsupported, unnatural and therefore stressed position which can cause pain.
A lack of conforming ability also often results in some parts of the body – namely shoulders and hips of side sleepers – feeling more pressure than other parts because of unequal support. Such pressure can be a source of significant discomfort. Having the right firmness is an important factor in preventing / relieving pain. Learn more: Mattress Firmness Guide & Comparison. The graph below shows the pain-relieving ability of the different mattress types based on actual owner experiences. The types that are better at reducing (back, hip and shoulder) pain are more supportive, less likely to sag and more likely to have effective conforming ability. Keep in mind that the chart represents what is often but not always the case; model or individual mattress may go against these findings somewhat. Sagging and loss of support (barring mechanical breakdown) is usually less of a problem with airbeds compared to most other bed types. And the air chambers inside an airbed provide at least fair conforming ability and allow for adjustable firmness / support to suit personal preference and sleep position.
Airbeds, however, with little or no comfort layer can be too firm on hips and or shoulders of small- to average-sized side sleepers. While memory foam mattresses can develop problems (sagging, excessive softness, and loss of support) these problems tend to not be as common or serious as they can be with innerspring-based mattresses (memory foam's main competition). Memory foam also provides good conforming ability for average- to large-sized people. Firmness levels tend to be mostly medium to medium-firm. Smaller-sized people may experience excessive pressure points as they tend to not exert adequate pressure on the mattress to benefit from the foam's conforming ability. Latex can develop body impressions and soften to some extent, but these problems tend to not cause widespread pain problems. Latex often conforms moderately to the body. Firmness tends to be medium to firm (but soft varieties are available). Hybrid mattresses often provide above-average support, but such support breaks down for at least 18% of owners within three years due to sagging.
Conforming ability tends to be good if at least two inches of memory foam is present. A variety of firmnesses are available. While waterbeds are often highly conforming, their support is questionable. At least 15% of owners claim that their waterbed causes back pain because of poor support. Firmness can be adjusted somewhat by adding or removing water. Innerspring mattresses often provide at least fair support, but such support breaks down for at least 20% of owners within three years due to sagging. Models with a significant comfort layer often provide fair conforming ability, while models with a minimal comfort layer often provide poor conforming ability especially for small- to average-sized people. Futon mattresses offer mostly fair support and conforming ability. Futons tend to be more firm than soft. While mattress support, mattress conforming ability, and mattress firmness are crucial factors for preventing / relieving pain, they are not the only factors. One's choice of pillow is important as well.
If your pillow – specifically its loft or height – is not compatible with your mattress – specifically its firmness level – then neck, upper spine, head and shoulder discomfort or pain are possible. See our pillow loft guide and calculators to learn how much loft may be best for you.Sleep matters -- so much so that six in 10 Americans crave sleep over sex. And the key to rest that's good enough to forgo sex just might be the mattress: Nine in 10 respondents in a sleep survey cited their mattress as an important factor in getting that coveted good night's rest. In 2010, Americans spent more than $5.8 billion on mattresses and box springs alone. But is this expense justified? How important are mattresses, really? Read on for the low-down on how mattresses affect health and sleep quality. 13 Legit Ways to Stop a Hangover The Most Common Yoga Injuries and How to Avoid Them 13 Social Good Mobile Apps for a Healthier You Mattress Matters -- The Need-To-Know
The first "mattresses" (read: piles of leaves, grass or straw covered in animal skins) were invented by cave men and women. Thousands of years later, the Egyptian pharaohs discovered the luxury of raising the bedding off the ground (though common folk continued to sleep on piles of palm fronds). Today, many Americans enjoy the luxury of mattress-induced sleep. Even those who aren't up on their mattress history know the value of a good night's sleep. The average person spends about one third of her or his life sleeping. For those who sleep less than that, sleep deprivation can have serious health consequences, including a sour mood (what college student doesn't know this to be truth), slower metabolism and impaired immune function There are lots of great tips for coping with sleep deprivation, but what if the cause is right under our backs? Low-quality, uncomfortable mattresses have been linked to sleep discomfort and pain, and chronic pain can prevent quality sleep. Fortunately, it's not all bad news.
While mattresses can hinder sleep quality, they can also improve it. Improved “bedding systems” (a fancy way of saying “things you sleep on”) have been linked to decreased pain and discomfort, especially in women. Quality sleep on a good mattress may also help decrease stress. The experts we spoke to said it basically comes down to personal preference. If we're comfortable, we have a better chance of sleeping well, and if we sleep well, we're more likely to stay healthy. Better Bedding -- Your Action Plan When it comes to purchasing the perfect mattress, it turns out there are a lot of mixed messages out there. Some research suggests that foam mattresses create backaches; others say foam helps pain. Some studies advocate for regular cotton mattresses while others say coils create backaches and that airbeds are the way to go. There's even controversy over the conventional thinking that a firm mattress is better for lower back pain. The reason for all this controversy is that sleep quality and comfort are so darn subjective.
