What the best mattress has

  • Adequate spinal support. Your mattress should allow your spine to assume the same natural curve when you lie down as when you're standing.
  • Motion isolation. Low-end innerspring mattresses transmit more motion from one person in the bed to another, while foam mattresses and high-end innersprings transmit less.
  • Freedom of movement. Some foam mattresses make changing positions difficult because of the way they conform to the body.
  • A good warranty. Although experts warn that a mattress may not last nearly as long as its warranty period, several do consider a long warranty a reliable sign of the manufacturer's confidence in the mattress's quality.
  • Warranty coverage for sagging. In addition to considering the length of the warranty, pay attention to how it covers sagging, the most common problem with aging mattresses.
  • The backing of a trustworthy manufacturer. If the manufacturer has a Better Business Bureau rating of B or better, you can feel reasonably confident that it will stand behind its warranty.

Know before you go

What size do you need? Standard mattress dimensions in the U.S. are: twin, 39 inches by 75 inches; double or full, 54 inches by 75 inches; queen, 60 inches by 80 inches; standard king, 76 inches by 80 inches; and California king, 72 inches by 84 inches. Some high-end mattresses don't come in sizes smaller than a queen, so make sure the mattress you try in the store is available in the size you want.

Will it fit in the door? Even within a given size, mattresses vary considerably in thickness. Experts recommend measuring all doorways, stairways and hallways to make sure the mattress can fit where it needs to go.

How do you sleep? People who normally sleep on their sides may prefer a softer mattress than back or stomach sleepers. However, a mattress of medium firmness is usually comfortable for everyone.

Do you overheat at night? Foam mattresses retain more body heat than innersprings and air mattresses. A latex foam mattress may provide better ventilation than memory foam.

Will you share the mattress? If your partner is a restless sleeper, you may prefer a foam mattress or an innerspring with pocketed coils, since these are generally better at isolating motion. On the other hand, the bounciness of an innerspring may make it more suitable for sex than a foam mattress that conforms to the body. If you strongly prefer a firm mattress while your partner prefers a soft one or vice versa, your best option may be a dual-chambered air mattress, which can be adjusted to a different level of firmness on each side.

Value expectations: The dollars and cents of it

Experts say you should never pay full price for an innerspring mattress. The retail markups on innerspring mattresses tend to be exceptionally high, as models are often priced to be sold at discounts of 50 percent or more. And don't ever be afraid to haggle when you're in the mattress store. If they know you're serious about making a purchase, salespeople may find a way to sweeten the deal, rather than watch you walk out the door.

Buying tactics and strategies

Visit manufacturers' websites. Before shopping, browse through the different lines to see which features they have, and print out details about the models you're interested in. This gives you a good starting point when you get to the store.

Start at the bottom of the price scale and work up. Mattresses vary tremendously in price, and all but the very cheapest are likely to be sturdy.

Rest on the mattress for at least 15 minutes. When trying out mattresses in the store, spend time on your back and both sides as well as your stomach, if that's one of your normal sleeping positions. If you sleep with a partner, try out mattresses together.

Check the firmness. If you have difficulty rolling over, the bed is probably too soft. On the other hand, if you can easily slide your hand under the small of your back while lying on your back -- or if you feel pressure on your hips and shoulders -- it's probably too firm.

Ask to see a cross-section of the mattress. Look at details like the coil size and density of an innerspring mattress, and the foam density and size of ventilation holes on a foam mattress.

For an innerspring mattress, consider a new box spring. Some sources say an old box spring can be kept if it's in good condition, but others say a new one will promote comfort and prolong the life of the mattress. Also, using an old foundation might void the mattress's warranty.

Look for a comfort guarantee. Many retailers will give you a trial period of two weeks to three months on a new mattress. Each store has different rules, and there may be a fee for returns or exchanges. Make sure to get the details in writing.

Ask about disposal of your old mattress. Some stores offer free disposal; others will charge a fee.

Read the fine print. Make sure the sales contract specifies that the store can't deliver a substitute brand or style if the one you want is out of stock. When your mattress arrives, inspect it to make sure it's the right one and that it's undamaged.

What's to come

According to research at WhatsTheBest-Mattress.com, buying mattresses online or over the phone has become more common than ever. However, most experts advise against buying a mattress this way, saying it's important to test a mattress in person before purchase. Editors of ConsumerReports.org say customers who buy a mattress online are more likely to return it than those who buy from a store. Even so, among mattress owners surveyed by SleepLikeTheDead.com, those who bought mattresses online, sight unseen, were just as satisfied with their purchases as those who tried them in a showroom. They suggest that a 15-minute test drive may not be an accurate gauge of comfort, and prices and return policies are often better online.
