Deciding what mattress to buy is enough to keep you up nights. The model names, while enticing, can be confusing and make it nearly impossible to compare a mattress sold at Macy's, for example, with one sold at Mattress Firm.

Throw in the aggressive sales tactics you still run into at many mattress stores, as well as the varying definitions of "firmness"—it's enough to make you want to lie down and take a nap.

"Don't be intrigued by freebies or health claims or other gimmicks that mattress retailers throw at you," says Claudette Ennis, Consumer Reports' market analyst for mattresses. "Make sure to talk to your physician or a sleep expert to figure out if you have special needs. Otherwise, go at your own pace and negotiate a deal when you find what you want."

Be it Sealy, Serta, Stearns & Foster, or Tempur-Pedic, we test each manufacturer's best-selling models. We also look at direct-to-consumer brands, such as Casper and Tuft & Needle, and bring in mattresses with innovative construction, such as the Purple, which has a rubberlike grid as a top layer to promote airflow.

More on Bedding

At CR, we buy and test queen-size mattresses because they're the most popular size. Using lab equipment and human subjects, we evaluate how well a mattress supports the body for both back and side sleepers, how easily sleepers can shift their weight without disturbing their partner, and how well the mattress will keep its shape over time.

And while our scientific ratings for support are a good proxy for how well you might sleep on a mattress, we also provide ratings for comfort and satisfaction that come from people who've actually lived with these mattresses—for up to 10 years in some cases. Our new comfort and owner satisfaction ratings are based on data from recent surveys on CR members' experiences with more than 74,000 mattresses purchased within the past decade. We asked members to rate the comfort of their mattress, and used the data to generate ratings by brand and type of mattress. Owner satisfaction is based on a member's overall judgment of such factors as firmness/softness, value, quality of sleep, and more.

Find the Right Mattress at the Right Price

The mattresses in our ratings range from roughly $275 to $4,950, but you don't have to spend a lot to get a comfortable mattress—in fact, many of our top-rated mattresses cost less than $1,200. To take full advantage of our mattress ratings, follow the steps below.

1. What Type of Mattress Do You Want?
CR tests innerspring, foam, and adjustable-air mattresses. Despite all the buzz about foam beds-in-a-box that ship straight to your doorstep, innerspring mattresses still account for most sales. These mattresses typically combine layers of springs and foam topped with padded fabric. But foam mattresses aren't just a solid block. Mattress makers have been experimenting with layers of foam and gels to improve sleeping comfort. The third type in our tests is adjustable-air mattresses, in which you can inflate air bladders to the firmness you desire, which works well for couples because each can set their side of the mattress to the firmness they like.

2. How Firm Do You Like It?
Manufacturers may describe a mattress as soft, medium, firm, or extra firm. But in our tests, we found that their descriptions don't always line up with our measurements. In our ratings, none scored higher than an 8 for firmness and only a few scored lower than a 2. It's best to try a number of beds to see what feels most comfortable for your sleeping habits.

3. What's Your Sleeping Style?
Most people sleep on their sides, but there are still those who prefer to splay out on their backs. To satisfy both types of snoozers, we test support for both side and back sleepers. The best mattress for side sleepers maintains the horizontal alignment of the spine while lying on your side. For back sleepers, the mattress that provides the best support maintains the natural curve of the spine while you're on your back.

4. Become Size-Wise
To further refine your choices, we rate mattresses for petite, average, and large/tall side sleepers and petite, average, and large/tall back sleepers. (The average is, of course, the average of petite and large/tall.) As you can see from our ratings, the best mattresses for smaller folks aren't always the most comfortable for larger people, so choose accordingly. For more information, see Best Mattresses for Couples.

5. Putting It All Together
If you sleep alone, your choices are easy. Just pick the type of mattress you want, your favorite firmness, and match the mattress to your size and sleeping style. For couples, it's more complicated because the best choice for one partner may not be best pick for the other. By using our ratings, you can drill down and make a comfortable compromise. And if you share your bed, also consider our stabilization score, which tells you how easy it is to change positions without bothering your mate.

6. Test It Out by Taking a Nap
If you're deciding between models and you're able to test them in the store, spend at least 10 minutes or more lying on the mattress to see whether it has your back. Sometimes though, you can't try before you buy (say, if you're trying a mattress from an online-only bed-in-a-box company). In this case, be sure to check the manufacturer's return policy, and note whether there are any fees or time limits on trying the bed at home.

Best Mattresses from CR's Tests

Our top-rated mattresses range from just over $900 to nearly $3,000. In terms of performance, Overall Scores range from 78 to 85. Here, CR members can see ratings for three key performance tests: how well the mattress supports an average-sized person who sleeps on her back or on her side, and stabilization (how much vibration is transmitted across the mattress.) Members can click on each mattress to see full ratings and reviews.

CR's take: The Avocado Green performs superbly in our side-support tests for average and large/tall sleepers and in back-support tests for petite, average, and large/tall side sleepers, earning a rating of Excellent. The Avocado is made of recycled steel pocket innersprings, and has latex foam padding and a certified organic cotton cover. It's not as stable as some other mattresses in our tests, though. If you sleep with a restless partner or don't like a lot of bounce, this mattress might not be the one for you. Members who bought an Avocado mattress gave it an Excellent rating for comfort and a Very Good score for owner satisfaction.

CR's take: The Casper Hybrid innerspring mattress earns an Excellent rating for all of our side sleeper support tests, making it a versatile bed. Large/tall back sleeper support earns a Very Good rating; petite and average back sleeper support ratings earn a Good. The mattress showed little wear after eight to 10 years of simulated use, and it's top-notch at muting vibrations, meaning there's little bouncing from across the bed. The Casper Hybrid isn't a very firm mattress, earning a 3 out of 10 (with 10 being the firmest). Overall, CR members thought their Casper innersprings were a nice choice; in our member survey, the product earns Very Good ratings for comfort and owner satisfaction.

CR's take: Petite and average back sleepers will appreciate that the Essentia Stratami earns an Excellent rating for support, and petite, average, and large/tall side sleepers will enjoy support that earns a Very Good rating in our tests. The Stratami is quite stable, meaning you'll barely feel vibration and movement across the bed, and it earns an Excellent score for durability, with no changes in performance after eight to 10 years of simulated use. This mattress weighs a hefty 122 pounds and has no grips, so if you're moving it, you may need help. CR members gave their Essentia an Excellent rating for comfort and a Very Good score for owner satisfaction.

CR's take: Casper's flagship The Casper foam mattress is a great option for back sleepers, earning Excellent ratings in our back-sleeper support tests for every body size. For side sleepers, this mattress is still a great buy, though it's not quite as strong for side sleeping support, with ratings of Very Good for each body size. In our stability tests, this mattress earns a Very Good rating. The Casper is slightly firmer than average, earning a 6 on our firmness scale. Casper foam mattresses earn Very Good ratings for comfort and owner satisfaction among CR members.

Best Adjustable Mattresses

CR's take: This recommended mattress has a firmness rating of 4 on our scale of 1 to 10, with 10 being the firmest, though it can be adjusted to an even softer firmness of 3. It earns a rating of Very Good for support for side sleepers and back sleepers of all sizes but doesn't stand out for any size in particular. It earns an Excellent rating in our stabilization test, meaning you should be able to shift positions with ease. Members give Sleep Number mattresses high ratings; the brand earns Very Good scores for comfort and owner satisfaction.

CR's take: Relatively new to CR's ratings, the Personal Comfort H10 Bed earns an Excellent rating for back sleeper support for all body sizes and a Very Good rating for side sleepers of all sizes. It earns a Very Good rating in our stabilization test, meaning you should be able to shift positions with ease, though you might feel your partner's movements slightly. It's a firm mattress, earning a 6 out of 10 on our firmness scale (10 being the firmest).
