With nearly a century of experience making mattresses, Serta has long promoted the idea of sleeping in comfort.

Even if you’ve never slept on a Serta mattress, you might know the brand. Most people have seen a Counting Sheep commercial or two.

The Serta iComfort mattresses are specially designed to provide support and cooling, but they come with another unique feature: You can customize the foam or hybrid options and upgrade from a basic bed to the mattress of your dreams.

Before we get into the specific details of the iComfort line, here’s a quick snapshot of the key benefits these mattresses offer, along with a few potential drawbacks to consider.


  • Unique carbon fiber memory foam promotes cooler sleep. Pages of reviews from satisfied customers rave about how well the cooling technology works. If you tend to sleep hot, this might be a good option.
  • All iComfort mattresses work with adjustable beds. Looking for the right mattress for an adjustable base? Serta has your back.
  • A range of mattress types means all sleepers can get comfortable. Different upgrades and firmnesses mean most people can find a mattress that meets their needs.
  • The iComfort line comes highly rated. In general, people seem to love these mattresses. Most of the iComfort line has an average rating of 4.5 stars or higher on Serta’s website and across other online retailers.
  • Serta only uses CertiPUR-US certified foam. This certification means the foam contains no toxic or ozone-depleting chemicals and meets standards for low emissions.
  • An ample trial period ensures you love the mattress. Serta and the other retailers we link to offer a trial period. You can try out your new mattress for a few months to make sure it works for you.

  • Your mattress might feel pretty firm. Some reviewers mention the medium-firm iComfort options feel firmer than they expected. If you need a softer mattress, you may want to opt for one of the plush models.
  • This mattress line can get a little pricey. Depending on the upgrades you choose, a queen-size mattress could range anywhere from around $1,000 to $2,400.
  • Buying online means buying sight unseen. When you purchase a mattress online, you won’t know exactly how it feels until you get it set up in your bedroom. (Tip: Always read the fine print to make sure you’re aware of any return shipping or restocking fees.)

Mattress prices can vary quite a bit based on size, materials, mattress type, and any special features.

In the budget category, you’ll typically pay between $300 and $600 for a basic, no-frills queen mattress when shopping online.

Most good quality mattresses from reputable brands will cost slightly more, depending on the features you want. You’ll often pay around $1,000 for a queen foam mattress in the middle of the price range, with hybrid mattresses costing a little more.

Mattresses in the luxury category typically start around $1,500 but can range into the thousands.

Prices for Serta’s iComfort line start at the higher end of the average category and extend well into the luxury mattress category.

With the exception of the Limited Edition cooling gel foam mattress, the most inexpensive queen option costs $1,299, barring any sales.

We’ve noted prices for queen mattresses below, dividing them into three price brackets:

  • $ = $1,000–$1,299
  • $$ = $1,300–$1,999
  • $$$ = over $2,000

Serta iComfort

  • Price: $
  • Type: foam
  • Height: 10 inches
  • Good for: side, back, and combination sleepers

The basic model of the foam iComfort mattress is designed to provide medium-firm support that works well for most sleepers.

Some reviewers say the mattress felt too firm for dedicated side sleeping, while others call it just right for side and stomach sleeping. Other people mention the good support it provides for back sleeping.

Foam mattresses can sometimes get a little warm. The iComfort series aims to address this concern with layers of carbon fiber memory foam and open cell memory foam that are made to work together to keep you cool as you sleep.

According to Serta, the carbon fiber improves durability while drawing heat away from your body. The breathable open cell foam is designed to boost airflow while adding soft support.

Since most reviewers praise the iComfort’s cooling features, it appears this technology does indeed do the trick.

A few reviewers do say this mattress began to sag after a year or two, but in general, people like the support and pain relief it provides. Reviewers also love the lack of motion transfer, with several saying they don’t feel their partner move at all.

Interested in even more cooling and support? Serta offers several upgrades that modify mattress features and price:

  • Limited edition. This 10-inch plush mattress ($) features a layer of cooling gel foam instead of carbon foam.
  • Cooling upgrade. This 11.5-inch firm mattress ($$) has extra layers of carbon and open cell foam for additional cooling.
  • Max cooling upgrade. Looking for the ultimate cool? Along with a bonus layer of cooling foam, this 12.5-inch mattress ($$) also has a cover made from fabric designed to feel cool to the touch and stay cool as you sleep. You can also choose your ideal firmness: This version comes in medium, plush, and ultra plush.
  • Max cooling and pressure-relief upgrade. Designed to provide both optimal cooling and comfort, this 13.5-inch mattress ($$$) contains a layer of breathable foam, which may support side sleepers and give them pressure relief. Choose between a firm, plush, and ultra-plush mattress to customize your comfort.

Which is best for me?

Side sleepers. You may benefit from the plushness of the limited edition. It will have more give to cradle your shoulders and not create pressure. The max cooling or the max cooling plus pressure relief upgrade in plush or ultra-plush would also be good options. In general, side sleepers tend to benefit from more pressure relief since side sleeping has the potential to increase pressure at the hips and shoulders.

Stomach or back sleepers. The firmness of the cooling upgrade will offer great support for these sleeping positions. The max cooling or the max cooling plus pressure relief upgrade in firm may also be good options.

Combination sleepers. You may prefer the plushness option that comes with the max cooling upgrade.

Serta iComfort Hybrid

  • Price: $$
  • Type: hybrid
  • Height: 12 inches
  • Good for: back, stomach, and combination sleepers

A hybrid mattress combines coil support with comfort layers made of materials like foam or latex. Hybrid mattresses provide good support for all body types, but side sleepers with lower body weights may not get enough cushioning or pressure relief from a firmer hybrid.

The iComfort hybrid features individually pocketed coils for improved support and motion isolation under memory foam layers. In the basic model, a carbon foam layer and a gel memory foam layer are designed to provide support, relieve pressure, and help you maintain a comfortable temperature for sleep.

A few reviewers confirm the low motion transfer, saying they noticed very little movement from their partner. People also praise the cooling features. Some say this mattress even helped ease their night sweating.

Most reviewers love this mattress. They call it comfortable and supportive, and say they wake up cool, refreshed, and free of pain. Although a few reviewers find it a little too firm, others enjoy the sturdy support.

Firmer mattresses generally work best for back and stomach sleepers. If you sleep on your side, one of the upgrades might provide the cushioning comfort you’re seeking:

  • Cooling upgrade. This firm, 12.5-inch mattress ($$) features an extra layer of open cell memory foam infused with cooling gel.
  • Max cooling upgrade. A mattress cover designed to stay cool to the touch and a bonus layer of cooling carbon memory foam might make this 13-inch mattress ($$$) ideal for people seeking the coolest comfort. This mattress comes in both medium and plush firmnesses.
  • Max cooling and pressure relief upgrade. Three inches of cushioning foam are designed to help relieve pain and pressure in this 14-inch option ($$$). Serta says an added layer of carbon foam helps provide optimal cooling. This mattress also comes in both firm and plush.

Which is best for me?

Side sleepers. The max cooling or the max cooling and pressure relief upgrades in plush may offer the pressure relief that side sleepers often require.

Stomach or back sleepers. Same as the non-hybrid mattress, the firmness of the cooling upgrade can offer great support for these sleeping positions. The max cooling plus pressure relief upgrades in firm may also be good options.

Combination sleepers. The max cooling upgrade has a medium firmness option that may be beneficial for combination sleepers who need to strike a happy middle ground between firm and plush.

Our editorial and medical affairs teams vet products for our reviews, looking at the below criteria:

  • Safety. All the mattresses we feature meet federal safety standards, complying with with the Federal Flammability Standard, 16 CFR part 1633, and 16 CFR part 1632.
  • Company reputation. We avoid brands that have been found guilty in a recent lawsuit related to business practices. We’ll include any potential red flags to help you make an informed decision.
  • Materials. We look for mattresses made of materials certified safe from a reputable third party.
  • Company policies. We make sure the companies offer warranties, in-home trials, and shipping and return policies that give you a chance to try out the mattress before officially deciding to keep it.

Serta mattresses are fairly common, so you’ll find them in many mattress retailers. You can visit a local brick-and-mortar store or use the store locator on Serta’s website to find an authorized retailer near you.

Prefer to buy online? Shop directly on Serta’s website using the links we’ve included above, or find the iComfort line at other online retailers, including US Mattress, Wayfair, and Amazon.

Just pay extra attention to the different return policies and in-home trials provided by each retailer. (Hint: Amazon might be super convenient, but it doesn’t offer in-home trial periods.)

Interested in the mattress but not the price tag? The iComfort line does occasionally go on sale. You may snag a great deal in your local store, but it’s generally worth comparing the store cost with online prices as well.

Choosing the right mattress can feel pretty overwhelming. Considering these important factors can help you begin narrowing down the possibilities and find the mattress that’s best for your sleep needs.

Mattress type

Foam or hybrid? Well, that can depend on what you need more of: firm support or pressure relief.

Foam mattresses can provide pressure relief, which can be a good option if you live with chronic pain or sleep on your side.

On the other hand, if your discomfort comes from too much cushioning (yes, that can happen) or you hate the sensation of sinking into your bed, you might sleep better on a hybrid.

You usually won’t feel “stuck” in the bed with a hybrid, so you’ll have an easier time changing positions as you sleep.

Hybrids generally provide more support than foam alone, making them ideal for back and stomach sleepers who need more support.

Cooling features

Feeling uncomfortably warm can easily disrupt your sleep.

Even the basic iComfort mattress is designed to sleep cool, but one of the cooling upgrades can improve your comfort and sleep if staying cool is a consistent struggle.

Upgrading to an extra layer of cooling foam may provide enough relief for some people. If you’ve had less success with other cooling mattresses, however, you might opt for the maximum cooling technology.

Even reviewers who regularly wake up sweating say the cooling cover and additional cooling foam helped them stay more comfortable through the night.


Research suggests medium-firm mattresses generally provide the ideal combination of sleep comfort, quality, and spinal alignment. If your spine falls out of alignment, you may wake up with discomfort, stiffness, and eventually, pain.

Firmness is very subjective, of course. What feels too firm to one person might feel just right to someone else.

Some people just can’t get comfortable on a firmer mattress. Side sleepers in particular may need the added cushioning and body contouring that softer mattresses can offer.

Since a firmer mattress can help align your spine properly, choosing the firmest mattress that still feels comfortable. If you don’t feel comfortable, you probably won’t sleep very well, and at the end of the day, good sleep quality is what matters most.

Overall, Serta has a good business reputation, according to the below criteria:

  • The company hasn’t been involved in any lawsuits related to business practices within the past 3 years.
  • None of Serta’s products have been recalled within the past 3 years.

However, as of 2022, the company has an F rating with the Better Business Bureau (BBB) and is not BBB accredited. If you’d prefer to buy a mattress from a company with accreditation and a better rating, check out our reviews of the best mattresses.

Keep in mind that business reputations can change at any time based on new customer complaints or filed lawsuits. It’s always a good idea to double-check this information before making your decision.

Serta is also committed to sustainability. According to its website, Serta uses eco-friendly components in its mattresses and prioritizes saving energy and reducing waste in the construction process.

A mattress is a significant purchase. Before you buy, you probably want to make sure the company will stand by its product and offer a good resolution if anything goes wrong with your purchase.

Reviews of Serta’s customer service are mixed. While the vast majority of reviewers praise the iComfort series, other reviewers mention a few key issues:

  • mattresses that sag after a year or two
  • trouble getting in touch with customer service
  • mattresses that never arrived

Serta does make an apparent effort to get in touch with customers who report mattress problems in a review: Customer service associates reply to reviews left on the product page on the Serta website.

When buying a mattress, especially online, remember to read the warranty before completing your purchase. Certain factors, such as the way you set up your mattress, might void your warranty. It’s also a good idea to know exactly what your warranty covers ahead of time.

Serta mattresses arrive uncompressed and wrapped.

Standard delivery gets the mattress to your door. If you need help setting it up, you have the option to upgrade to white-glove delivery when ordering a mattress directly from Serta.

With white-glove delivery, the delivery service will set up your new mattress and take away your old one for disposal.

Some reviewers say the iComfort mattresses had no noticeable off-gassing (chemical smell). Others say the mattress gave off a strong smell at first, but it faded within several hours. A few reviewers say the smell persisted for several days.

Off-gassing is fairly common in new mattresses, but it’s something to consider if you’re particularly sensitive to chemical odors.

No product is perfect, and not every mattress works for everyone. That makes it essential to try out a new mattress before you buy it.

Of course, you can’t really try out a mattress if you buy it online, so most reputable brands offer a trial period and allow you to return your mattress within a certain time window for any reason.

Serta offers a 120-day trial period for its mattresses. If you buy your Serta mattress from a different online retailer, be sure to check the trial period, since it may vary.

Keep in mind that returns aren’t always free. Depending on where you purchase your mattress, you may need to cover return shipping costs and a restocking fee.

Serta charges a restocking fee of 15 percent, along with $200 for return shipping.

Serta also allows you to exchange your mattress during the trial period, but you won’t get another trial period after making the exchange.

To return or exchange a mattress purchased on Serta’s website, you’ll need to email or call customer support.

If you purchased it from another website or local store, check your receipt for more information on the return process.

Looking to get a cooler night’s sleep without compromising on support?

All mattresses in Serta’s iComfort line boast cooling technology, but the firmness options and upgrades give you a total of 14 different mattresses to choose from. This variety makes it easier to find the ideal mattress for any sleep needs.

While some of the upgrades can get a little expensive, many reviewers see their improved sleep as well worth the cost.
