Common claims that haven’t held up in our tests: Foam Layers Make a Better Bed More innerspring mattresses now include foam on top. But the foam is often too thin to make a difference on some of the hybrid models. Hybrid innerspring models that scored well in our tests had a foam layer several inches thick, though performance still varied. More Coils, the Better The better innerspring models we tested had 600 to 1,000 coils. But even if one mattress has more coils than another, the coils could be made of thinner-gauge metal. You’ll also hear about coil variations such as Bonnell (hourglass type), continuous wire, and individually pocketed springs. None of those is inherently superior. Gel Provides a Cooler Sleep Some mattresses (noted in our Ratings) have a layer of gel-infused foam that’s supposed to provide a cooling effect.
But that layer is buried beneath other layers. While our tests have shown that innerspring mattresses containing gel did tend to sleep slightly cooler, the reverse was true with gel-infused foam beds. Extra Lumbar Support Helps Back Sleepers A special lumbar-support zone is one of many ways manufacturers try to differentiate their product lines. But there’s no guarantee that it makes any real difference, and it hasn’t shown significant benefits in our tests. Forget About Comparison Shopping If you like a mattress at one store and ask elsewhere for something similar, you're likely to be steered toward a same-brand mattress claimed to have the same construction, components, and firmness. But they’re probably not the same. Mattress makers offer some lines nationally, but when those brands are sold through major chains such as Macy's, Sears, and Sleepy’s, they're for lines exclusive to those chains. And manufacturers don't publish a directory of comparable mattresses.
When we went to three bedding chains and asked for mattresses similar to those we’d bought at three department stores, five of the six were way off the mark. So use our Ratings as a guide, and insist on the precise make and model that scored well in our tests. Also check our Ratings of mattress brands and stores, based on subscriber surveys. If possible, lie on any mattress that you’re considering. Wear loose clothes and shoes you can slip off. Make yourself comfortable, and shoo away the salesperson if you’re feeling pressured. Salespeople should expect you to take your time. Spend at least five or ten minutes on each side and on your back (your stomach, too, if that's a preferred sleeping position). Panelists who took beds home for a month-long trial rarely changed the opinion they formed after the first night. Shopping online or at a warehouse club? Tryouts aren’t usually an option, so checking return policies before you buy is extra important. Make sure the store offers a full refund or credit toward another mattress.
Return periods, often called “comfort guarantees,” range from a couple of weeks to 120 days. Some retailers, including Macy’s and Sears, charge a 15-percent restocking fee. Costco and some online sellers provide free pickup if you want a refund or exchange, but otherwise, you’ll have to pay for it—or cart the mattress to the store. And you’ll be responsible for any damage. Once you’ve settled on a model, try to bring the price down. Many businesses, such as warehouse clubs, have fixed prices and won’t budge. But for retailers that do negotiate—particularly specialty chains—huge markups allow them to lower prices by 50 percent or more during their frequent sales. Our recommendation: Any time of year, insist on a sale price you’ve seen for the mattress you know you want, and don’t be afraid to walk out if you feel you’re getting a raw deal. Don’t Be Bullied Into Buying a Box Spring You might not need it. For an innerspring mattress, the box spring (also called a “foundation”) is a wood frame enclosing stiff wire and covered with fabric to match the mattress.
For foam or adjustable-air mattresses, it’s a box several inches high. If you're switching to a foam or adjustable-air bed from an innerspring, you'll need a boxy foundation that lacks springs and wire. Otherwise, if your box spring isn't broken and is still structurally sound, consider keeping it and saving money (roughly $150 to $300 for a queen-size). One caveat: Some brands require you to buy their box spring to receive full warranty coverage. It can range from 10 to 25 years and covers only manufacturing defects such as sagging and loose or broken coil wires. Coverage is frequently prorated, meaning that it decreases over time. Never accept delivery without inspecting the mattress (and the box spring, if you buy one) for stains and other damage. Also be sure that the mattress has a label that states “all-new material” before you send the driver on his way. If it’s not there, refuse delivery. And keep it on afterward in case you do have to file a warranty claim in the future.
Related to Back Pain Best Mattress for Lower Back Pain Study Disputes Long-Held Belief by Some Doctors That Firmer Bedding Is Better Nov. 13, 2003 -- For years, many people with back pain have been advised to sleep on a firm mattress. But a new study shows that might just add to the nightmare of their morning-after misery. Researchers in Spain say that people who sleep on a medium-firm mattress were twice as likely to report improvements in lower back pain compared to those sleep on more firm bedding. They reach this conclusion after replacing bedding of 313 patients with a history of back pain with new "firm" or "medium-firm" mattresses. The patients didn't know which mattress type they received. This study, published in the upcoming issue of the Lancet, is among the first to test the popular belief -- at least among some orthopaedic doctors -- that the firmer a mattress is, the better it is at preventing or relieving lower back pain. While there's little hard scientific data to support that firm mattresses are better -- only a handful of studies have been conducted -- the Spanish researchers say that about three in four orthopaedic doctors recommend firm mattresses to their patients.
In fact, a survey of Atlanta-area orthopaedic surgeons indicates that two in three said they recommend a firm mattress to their patients, and most believed that a mattress' firmness had a definite role in managing back pain. This finding, by Emory University orthopaedist Howard I. Levy, MD, was presented at the 1996 annual meeting of the American Association of Orthopaedic Surgeons. But chiropractors have long argued that firm mattresses are not the best choice, says George McClelland, DC, spokesman for the American Chiropractic Association. "Traditionally, what we have recommended is that a moderately-firm works best, or when using a firm mattress, you should add a 1½- to 2-inch thick padding on top of it," he tells WebMD. "It's wonderful to be validated by some form of research." McClelland says that this extra padding -- or using a medium-firm mattress without the extra padding -- better adapts to the natural curvatures in the spine. This padding is available at most stores that sell mattresses or bedding supplies.
"The spine is not a straight line, and padding or a moderately firm mattress 'gives' better to the concavities and convexities of the spine," he says. "A younger spine may tolerate a firm mattress perfectly well. But as we get middle years any beyond, when back pain is more prevalent, we find that more equalized support seems to be better." The researchers, led by Francisco Kovacs, PhD, who operates an independent medical research company in Palma de Mallorca, Spain, say that a medium-firm mattress leads to better "pressure distribution" when lying in bed, resulting in less pain while lying or after getting up. But McClelland and others say you also shouldn't use a soft mattress, because it doesn't provide enough support. "From my own perspective, if a mattress is soft or too hard, it's not comfortable," says orthopaedic surgeon Dana C. Mears, MD, PhD, of the University of Pittsburgh Medical Center. "Something in the middle works best for me -- a medium-firm mattress.
