Sealy is a well-known mattress brand that has spent almost a century and a half working to provide customers with comfortable, supportive mattresses. One key selling point of Sealy mattresses is the brand’s trademarked Posturepedic technology.

Posturepedic, which Sealy developed with help from orthopedic specialists, is based on body weight distribution during sleep.

Typically, you’ll sleep with your head in the upper portion of the bed and your legs in the lower section. That leaves your torso and hips — about half of your body weight — in the middle region of the mattress.

Your low back, spine, and hips are key areas in need of support during sleep. When your mattress doesn’t provide enough support, you’re more likely to wake with discomfort and pain.

Beds with Posturepedic technology aim to prevent this problem with a reinforced mattress center. A layer of dense memory foam, plus extra coils in their hybrid beds, provide a sturdier mattress middle designed to promote better spinal alignment and more restful sleep.

Many, but not all, Sealy mattresses feature this targeted support. We’ve got the details below.

Mattress prices can vary quite a bit, depending on materials, mattress type, construction quality, and more. Queen mattresses usually cost somewhere in the neighborhood of $1,000, though you can often find discounts.

Sealy’s Posturepedic mattresses come with different features in varying firmness levels, so you’ll notice a range of price points. Prices will vary by retailer, since Sealy doesn’t sell these mattresses directly.

Here’s our breakdown for queen mattress prices:

  • $ = under $1,250
  • $$ = $1,250–$1,750
  • $$$ = over $1,750

Posturepedic technology appears in three of Sealy’s four mattress lines: The Response line, the Conform line, and the Hybrid line. Each of these lines has three collections: Essential, Performance, and Premium.

The Essential collection features their most basic mattress models, which do not have Posturepedic technology. You’ll find Posturepedic technology in the Performance and Premium collections.

Sealy Posturepedic Response

Sealy Posturepedic Response Performance

  • Price: $
  • Type: Hybrid
  • Height: 11.5–13.5 inches
  • Firmness: Plush, cushion firm, firm

Sealy describes their Response line as innerspring mattresses, but they can actually be considered hybrids since they feature two layers of foam over the coil support system. A traditional innerspring mattress typically has only a thin topper over the coils.

Along with Posturepedic technology, the Performance mattress also features individually pocketed coils for targeted support and motion isolation, and a dense border of coils around the outside of the mattress for edge support.

Above the coils, layers of breathable foam and gel-infused memory foam work to cushion and contour to your body to relieve pressure. The mattress cover features moisture wicking technology to help keep you cool and comfortable as you sleep.

Many reviewers like this mattress. On Sealy’s website, it has an average rating of 4.6 (out of 5) from more than 4,000 reviews.

People note the difference the reinforced middle makes, saying it helps them feel more supported as they sleep. A few people did raise some concerns over durability, saying the mattress began to sag after just a few months.

Sealy Posturepedic Plus

  • Price: $
  • Type: Hybrid
  • Height: 13–15 inches
  • Firmness: Ultra soft, soft, medium, firm, ultra firm

The Posturepedic Plus features individually wrapped coils, densely packed for support, and the same reinforced border as the Performance mattress.

Two memory foam layers work to provide cushioning and support above the coils. It also includes cooling gel memory foam with reinforced center support and responsive memory foam.

The mattress cover was designed to feel cool to the touch and also features allergen protection to help keep the mattress free of mold and dust mites.

The Posturepedic Plus comes in five firmness options, so you have an even better chance of finding the mattress that provides the right combination of comfort and support.

Keep in mind that these mattresses are taller than most standard mattresses. The soft and ultra soft versions also feature sewn-in pillow tops that add even more height, so you may need to invest in new bedding and deep pocket sheets to get the right fit.

A few people say the pillow top versions seem to trap more heat, but others praise the cooling technology and say it really makes a difference for their sleep.

Reviewers generally call this mattress comfortable and supportive, saying it helps relieve pain and improve their sleep. Many satisfied customers say they’d buy it again.

A few people mention poor quality construction, though, and some reviewers say the mattress began to break down after just a year. According to a few reviewers, the mattress works well for people sleeping alone but performs less ideally with two sleepers.

Sealy Posturepedic Conform

Sealy Conform Performance

  • Price: $–$$
  • Type: Foam
  • Height: 10–12 inches
  • Firmness: Plush, cushion firm, firm

Prefer a foam mattress? Sealy’s Conform line offers options to consider in a number of firmness choices.

In the Conform Performance mattress, layers of foam work together to provide support and comfort. Memory foam and two types of gel-infused foam add cushioning and are designed to help you maintain a comfortable sleeping temperature.

The dense foam in the middle reinforces the mattress to help keep your body aligned and supported however you position yourself as you sleep. The mattress cover also features moisture wicking technology for warm sleepers.

Despite the layers of foam, several reviewers confirm this mattress does sleep cool, and reviewers praise this mattress overall. People say it has great motion isolation, feels comfortable and cool to the touch, and helps them sleep better and wake up without pain.

A few people do say the edges could have been more supportive, and others note that the mattress began to sag in the first year. Some say they never got used to the firmness.

Sealy Conform Premium

  • Price: $$$
  • Type: Foam
  • Height: 12 and 13 inches
  • Firmness: Ultra plush and firm

The Premium option in the Conform line has a similar construction to the Performance mattress, including the dense foam Posturepedic support at the mattress center.

This version also comes with an additional layer of cooling gel foam and a mattress cover that stays cool to the touch. The Premium mattress also features reinforced edges, designed to allow you to use the mattress from corner to corner.

For the most part, reviewers love this mattress. People call it comfortable and supportive and say it does wonders for back and neck pain. Several reviewers also praise the cooling technology, saying this mattress sleeps cooler than other memory foam beds.

Since this mattress is thicker than many standard foam mattresses, it may provide better support for people with higher body weight.

Sealy Posturepedic Hybrid

Sealy Hybrid Performance

  • Price: $$–$$$
  • Type: Memory foam and spring coils
  • Height: 13 and 13.5 inches
  • Firmness: Plush, cushion firm, firm

Foam mattresses may feel soft, and they’re designed to isolate motion, but some people need more support than an all-foam bed can provide. If that’s the case for you, a hybrid mattress may offer a good alternative option to consider.

Hybrids combine coil support with layers of comfort materials for a mattress that offers a blend of support and comfort. Layers of open-cell and gel memory foam rest over the coils to cushion and work to keep sleepers cool. The mattress cover also draws away moisture.

Several reviewers praise these cooling features, saying they do make a noticeable difference. People also loved the good motion isolation and the reinforced edges of this mattress.

Some people say the edges seemed less supportive as time went on, but other reviews say this mattress remains supportive and comfortable after several months of use. A good mattress, of course, should last several years.

Sealy Hybrid Premium

  • Price: $$$
  • Type: Memory foam and spring coils
  • Height: 14–15 inches
  • Firmness: Ultra plush, plush, firm

A few key differences set the Hybrid Premium apart from the Performance, settling this version firmly into the luxury mattress category.

Like other Premium mattresses Sealy offers, it features a cooling mattress cover along with an additional layer of foam designed to feel cool to the touch.

Allergen protection in the mattress cover also helps keep your mattress fresh and clean. In the center of the mattress, tighter clusters of flexible coils work in tandem with dense memory foam to provide stronger support.

A few people say the cooling features didn’t have as much of an effect as they’d hoped, but most reviewers rave about how comfortable the bed feels. People love the lack of motion transfer, and several reviewers say they wake feeling truly refreshed and free of pain.

Side sleepers in particular note the great pressure relief, and people praise the way the mattress contours while still providing good support. By and large, people love and recommend this mattress, though some say they didn’t think it’s entirely worth the hefty price tag.

While you can’t buy these mattresses from Sealy, you can purchase them from many online and brick-and-mortar mattress retailers. We’ve included shopping links for US Mattress, but Sealy mattresses are widely available. You’ll likely find them at your preferred retailer.

Different retailers name and list these mattresses differently, which can create some confusion as you shop. Typically, you’ll find a clue to the model directly in the name, since most retailers give product names that include size, firmness, and mattress height.

For example, at US Mattress, the Sealy Hybrid Premium goes by the name of “Sealy Posturepedic Hybrid Premium Silver Chill Firm 14 inch Mattress.” Quite a mouthful, but it gives you everything you need to know.

The higher price tag can make these mattresses less affordable for shoppers on a tight budget, but many online retailers will offer discount codes from time to time.

These mattresses all feature Sealy’s Posturepedic technology, but beyond that, they do have some pretty significant differences. Some of these elements may not matter much to you, but others could make the mattress less than ideal for your needs.

As you shop, you’ll want to consider:

Mattress materials

Foam mattresses work well for many people, especially side sleepers and couples who want good motion isolation, but not everyone likes them. Some people feel too hot on foam, while others dislike the way these mattresses contour to the body.

Hybrids have a layer or two of foam or other padding, but these comfort materials rest on top of coils that provide support for all sleepers. They may not feel quite as soft as a foam bed, but they may provide more durability and firmness to stomach sleepers and people with higher body weights.

Generally speaking, hybrid mattresses tend to stay cooler than foam, so they may be a better option for the hottest sleepers. One small 2010 study suggests that mattresses constructed with spring coils and foam and designed for specific sleeping positions and body types can help relieve discomfort and pain and improve sleep quality for people living with chronic back pain.

Always look for the CertiPUR-US seal when choosing mattresses containing foam. This certification means the foam meets indoor air quality standards and doesn’t contain any toxic chemicals or heavy metals.

Sealy uses only certified foam in their mattresses.


You want a mattress that’s firm enough to provide good support, but you also want to feel comfortable when you lie down. If your mattress feels uncomfortable, you probably won’t sleep very well.

One mattress won’t have the same feel to everyone, since body weight and sleep position can affect your perception of firmness as well as the type of mattress you need. Softer mattresses can provide better pressure relief, while firmer mattresses tend to provide better support and spinal alignment.

In general, side sleepers may find the ideal comfort and pressure relief for their hips and shoulders from Sealy’s ultra soft/plush and soft/plush options.

Back and stomach sleepers will likely find cushion firm and firm mattresses most comfortable and supportive, and combination sleepers might find the cushion firm options ideal to accommodate whatever position they’re in.

If you’re not sure what firmness option to opt for, research suggests medium-firm mattresses provide a good blend of comfort and support for most people.


Overheating and sweating at night can disrupt your sleep, so experts typically recommend sleeping in a cooler room for better quality sleep.

A mattress that traps heat can still leave you uncomfortably warm, however, even in a cool room. Many mattress brands use gel infusions and other types of cooling technology in their mattresses to help you sleep more comfortably.

If sleeping hot isn’t a problem for you, you can probably take or leave this cooling technology. If you do tend to sleep on the warm side, it may be worth investing in a mattress with better cooling features, like the additional cooling foam or stay-cool covers in Sealy’s Premium mattresses.

You may also want to consider hybrids, since they tend to trap less heat than all-foam mattresses.


Taller mattresses tend to be more durable, since additional layers and coils provide more depth and support. A mattress with more height will usually provide better support to people with higher body weights.

A foam mattress of 12 or 13 inches, for example, will probably feel more supportive than a foam mattress of only 10 inches. People with lower body weights, however, may find some taller mattresses too firm.

The height of your mattress can also be an important factor if your bed frame is higher off the ground or you have trouble getting in and out of bed. Even an additional inch or two can make for some uncomfortable and awkward maneuvering.

You’ll also need deep pocket sheets for a mattress over 14 inches tall — an important drawback to consider if you like your current sheets and bedding.

Sealy’s business reputation is fairly good, based on these criteria:

  • They have an A+ rating from Better Business Bureau. Their parent company, TempurSealy International, has an A- rating.
  • The company has faced one lawsuit within the last 3 years. A Kansas man initiated a class action lawsuit in 2017, saying Sealy had failed to honor the warranty on his mattress. The case was dismissed a few months later when he dropped the suit.
  • Sealy hasn’t recalled any mattresses in the United States in the past 3 years. In 2019, Sealy Korea issued a recall for memory foam mattresses containing radon, but these mattresses weren’t made or sold in the United States.

Sealy states on their website that they make their mattress in the United States. They don’t offer much information about the materials in their mattresses, however.

Reviews on Sealy’s website praise the company’s customer service, for the most part. You can’t purchase these mattresses from Sealy, though, so you’ll also want to consider what customers have to say about the retailer you plan to purchase your mattress from.

It’s pretty tough for any company to earn perfect customer service reviews, but you can usually get an idea of how a company takes care of their customers by looking for patterns in reviews.

Before you make a purchase, it’s always a good idea to read some reviews to get more insight on whether the retailer responds to customers quickly and honors their policies. Some things to consider:

  • Does it seem like they honor the sleep trial and warranty?
  • Do they offer easy returns or exchanges?
  • Do people generally say they deliver the mattress in a timely manner?
  • Do they communicate about any shipping or delivery delays?

We’ve included shopping links for US Mattress, which offers a warranty and at-home trial for mattresses purchased through them. They respond to customer inquiries and, according to feedback from customer reviews for these mattresses, seem to provide good customer service.

A new Sealy mattress will arrive wrapped in plastic, fully expanded.

Some delivery services only offer no-contact delivery and will leave the mattress outside your door. Others offer setup and delivery for an additional fee. US Mattress does offer this service, if you feel uncertain about moving the mattress yourself.

You can sleep on your mattress as soon as it arrives, but you might notice some faint off-gassing. This chemical smell is fairly common in new mattresses, especially those with foam layers.

A few reviews did mention some mild off-gassing, but it didn’t seem to be a significant problem for most people. Opening a window will often help the smell fade faster, if it does bother you.

When purchasing a Sealy mattress from a third-party retailer, you typically won’t be able to return that mattress directly to Sealy. With that in mind, it’s important to carefully review the return policy before you buy your mattress.

Some retailers offer free returns and return shipping, while others charge fees to return the mattress.

  • US Mattress, the retailer we’ve provided links for, allows you to return mattresses during the trial period. The trial period is 120 nights.
  • US Mattress charges a processing fee when you return a mattress during the trial period. Other sites, like Wayfair, do not.
  • To start a return, you’ll need to contact customer service through the retailer’s website. Save your receipt after making your purchase, since you’ll need this information for your return.

Your body will usually need some time to adjust to a new mattress, so many mattress retailers encourage you to try the mattress for 30 nights before returning it. If you still feel uncomfortable after sleeping on the mattress for a few weeks, it’s probably not right for you.

Sealy’s Posturepedic mattresses may provide the support you need for good sleep. Some reviews suggest these mattresses may not be the most durable option on the market, but many people describe them as quality mattresses that promote cool, comfortable rest.
