Sealy Vs. Serta Mattress Review

When you’re shopping for a new mattress, the range available can feel overwhelming. With so many similar mattresses out there, how can you tell which one will be best for you? A common debate amongst mattress shoppers is whether to opt for a Sealy vs. Serta mattress. Both brands produce similar ranges, so being able to tell them apart is crucial when you’re trying to pick between them.

The Sealy Posturepedic and the Serta Perfect Sleeper ranges provide consumers with a high level of choice between three innerspring, hybrid and memory foam mattresses in a variety of firmness options. Although the Sealy Posturepedic and Serta Perfect Sleeper collections are somewhat similar, there are some significant differences when it comes to mattress construction, which you should be aware of when choosing between Sealy or Serta.

The best way to make this critical decision is to read unbiased Sealy vs. Serta reviews that give you an expert take on which mattress range has the most to offer. In this honest mattress review, we’ll tell you everything you need to know about Serta vs. Sealy mattresses to help you figure out which is best for your needs and budget.

Serta Perfect Sleeper vs. Sealy Posturepedic at a Glance

To help you compare Serta and Sealy mattresses, let’s start with a quick overview of the Sealy Posturepedic and Serta Perfect Sleeper collections.

Sealy Posturepedic mattresses all come with additional supportive reinforcement around the lumbar region to give you extra support for your lower back and core muscles. This feature helps to promote healthy spinal alignment during the night, which means that these mattresses could help with lower back pain.

Sealy has split its Posturepedic collection into three ranges: Response, Conform and Hybrid. The Sealy Response mattress is a traditional innerspring, and the Conform is a memory foam mattress. Each range comes in a variety of models that become more expensive as their features become more advanced. Each model comes in a wide choice of firmness settings, so you should be able to find a Sealy Posturepedic mattress to suit your sleep position and sense of comfort.

The Serta Perfect Sleeper range also features innerspring, memory foam and hybrid mattresses in a variety of firmness settings. The range focuses on beds that sleep cool and provide a good level of motion isolation.

One of the key things you need to know when weighing up Serta Perfect Sleeper vs. Sealy Posturepedic is that both lines provide a significant amount of choice, and you’re almost certain to find a mattress from either range that suits your needs and budget well. However, it’s also important to be aware that both ranges have questionable durability and lack strong edge support, so it’s reasonably likely that your mattress will start to sag sooner than some comparable brands would.

So, which is better, Sealy or Serta? The answer to this question comes down to your tastes and needs, as what suits one sleeper may not suit another so well. In the next part of this Sealy and Serta beds review, we’ll explain each range in greater detail to help make your decision a little simpler.

Sealy Posturepedic Mattress Construction

Whether you choose a Posturepedic Response, Conform, or Hybrid mattress, you will get the same key feature of the Posturepedic range- an extra panel in the lumbar region of the mattress to provide additional support for your lower back. This improves spinal alignment while allowing pressure relief in other vital areas where you need it.
Although all Sealy Posturepedic beds have this feature in common, there are major differences in construction, depending on which line you choose. Let’s take a closer look at the Sealy Posturepedic mattress range.

Response Line

The Sealy Posturepedic Response line is a collection of innerspring mattresses with a very responsive feel. This gives you the sensation of sleeping ‘on’ the mattress instead of the feeling of sleeping ‘in’ the mattress like you would on a memory foam bed.
Sealy has split its Response Line into three further sub-collections. These are called Essential, Performance and Premium. As you move up the collections, you get more advanced features, which means that Essential mattresses are the cheapest and Premium mattresses the most expensive. However, every bed in the Response line features a coil support system that provides a responsive sleep surface with less body contouring.

If you pick a mattress from the Performance or Premium collections, you will get additional reinforced support for key areas of your body known as Sealy’s Posturepedic technology. Therefore, the mattress can provide a consistent level of support across its entire surface.

Conform Line

Sealy Posturepedic Conform mattresses feature adaptable memory foam comfort layers to provide a deep hugging sensation when you lie on the bed. So, you will experience deep pressure relief and feel like you are sleeping ‘in’ instead of ‘on’ the bed. The type and formulation of the foams used depends on which Conform model you select.
Like the Response Collection, Sealy’s Conform mattresses are available in Essential, Performance and Premium. Whichever model you choose, your mattress will feature a supportive base made from Sealy Support Gel Foam. This layer contains cooling gel particles that can wick away body heat while you sleep. The Sealy ComfortSense Foam comfort layer can mold closely to your body and provide a soft, pressure-relieving sleep surface.

If you choose to buy from the Performance and Premium collections, your mattress will contain an additional layer of Sealy Chill Memory Foam in the comfort system. This layer provides extra breathability and can transfer heat away from your body, helping you to sleep far cooler than you would on traditional memory foam. These collections also feature the Posturepedic technology we mentioned in the previous section, providing you with additional support where you need it most.

Hybrid Line

The Sealy Posturepedic Hybrid Line provides a sort of middle ground between the Response and Conform lines by mixing the responsiveness and support of innersprings with adaptable memory foam comfort layers that provide a hugging sensation and deep pressure relief. Like Posturepedic’s other lines, it has Essential, Performance and Premium collections.
Like the Response line, the Hybrid line gets its support from an innerspring base unit made from individually pocketed coils. This type of support system reduced motion transfer far better than a traditional matrix system. If you choose an Essentials hybrid mattress, this comes with a comfort layer made from Sealy’s ComfortSense foam that can conform to your body and relieve pressure.

If you buy from the hybrid Performance or Premium collections, your mattress will have a comfort system made from Sealy Immersion Advanced Memory Foam. This foam is built using open cell technology, which gives it a less dense structure than regular memory foam. Therefore, it is more breathable and allows heat to escape while you sleep, providing a cooler sleeping surface. It also makes the foam more responsive, so you’ll get a bouncier feel like you would expect from a spring mattress but with the pressure relief of memory foam. Like the other two lines, Performance and Premium hybrid mattresses come with Sealy’s Posturepedic technology for additional lumbar and core support.

Serta Perfect Sleeper Mattress Construction

Like the Posturepedic brand, Serta Perfect Sleeper mattresses come in a choice of three construction types: innerspring, hybrid, or latex. To see how these beds compare to the Posturepedic range, let’s dive straight into our Serta beds review.


The Serta Perfect Sleeper Innerspring mattress collection is most suitable for those that like a traditional mattress. It gives shoppers a choice between three different types of steel coil support systems. The first is a continuous support innerspring system, which is the most basic option. Alternatively, you can choose an individually wrapped coil support system featuring either 739 or 886 individual springs. These two systems also feature additional foam edge support around the perimeter of the mattress, which helps to improve durability while allowing you to sleep across the entire surface of the bed, including the edges, without any roll-off effect.

Memory Foam

The Perfect Sleeper Memory Foam mattresses feature a supportive base unit made from dense foam to promote healthy and pain-free spinal alignment. Their comfort systems have layers of Serta’s signature Cool Action Gel Memory Foam. This foam is infused with gel particles to wick heat away during the night, keeping you cool and comfortable. These particles also help to increase the level of support offered by the mattress. The comfort layers are highly adaptable, molding to the shape of your body to relieve pressure and discomfort while you sleep.

Serta Perfect Sleeper memory foam mattresses come with additional foam reinforcement around the perimeter, which provides more robust edge support and helps to prevent sagging. It also increases the surface area of the mattress that is available for you to sleep on, which means you can sleep or sit up to the edges without experiencing a roll-off effect.


The Serta Perfect Sleeper hybrid model is called the Luxury Hybrid Glenmoor Super Pillow Top. It combines the support and breathability of a support core made from individually wrapped steel coils with a comfort layer made from Serta’s signature Cool Twist Gel Memory Foam. This material can adapt to the shape of your body to give a hugging sensation while providing excellent pressure relief. The foam has a gel particle infusion that transfers heat away from your body during the night.

Serta vs. Sealy Mattress Firmness

Both the Sealy Posturepedic and the Serta Perfect Sleeper mattress collections offer a wide range of firmness options that vary depending on which construction type you choose. To help you understand how the Serta Perfect Sleeper vs. Sealy Posturepedic mattresses compares in terms of firmness, let’s take a look at the various settings available in each collection in more detail.

Each branch of the Sealy Posturepedic mattress line comes in the following firmness settings:

  • Response: This mattress line comes in Plush, Cushion Firm (medium firm) and Firm unless you choose the Premium option, in which case the Firm mattress setting is replaced by Ultra Firm
  • Conform: If you choose the Essential or Performance versions of the Sealy Posturepedic Conform mattress line, you can select between Plush, Cushion Firm, or Firm. The Premium version is available in Ultra Plush and Firm only.
  • Hybrid: The Posturepedic hybrid line is available in Firm only if you choose the Essential version. The Performance model is available in Plush, Cushion Firm and Firm, and the Premium model comes in Ultra Plush, Plush, or Firm.

The Serta Perfect Sleeper mattress collection also offers consumers an extensive range when it comes to firmness options. The firmness settings for each line are as follows:

  • Innerspring: This line is available in a range of settings from soft to firm. If you select the softest setting, your mattress will contain an additional layer of PillowSoft foam to provide extra contouring and plushness
  • Memory Foam: The Serta Perfect Sleeper memory foam mattress range comes in two firmness options: medium firm and firm. The medium firm option contains an extra gel memory foam comfort layer to provide a little more softness and cushioning than the firm version.
  • Hybrid: The Serta Perfect Sleeper hybrid mattress comes in a medium-soft firmness setting only.

As you can see, the Sealy Posturepedic collection offers a little more choice in terms of firmness options across all its lines, while the Serta Perfect Sleeper collection does not produce each type of mattress in a full range of settings. However, you should be able to find a firmness setting to suit you from either brand.

Serta vs. Sealy Mattresses: Sleeping Position and Body Type

Both the Sealy Posturepedic and the Serta Perfect Sleeper mattress collections feature a wide range of construction types and firmness options, so you should be able to find a mattress to suit your sleeping position from either brand. When it comes to accommodating a particular position, there is really nothing to give one manufacturer an edge over the other.

The Sealy Posturepedic mattress collection is generally accepted to suit all body types, and it has garnered positive reviews from light and heavy-weight sleepers alike. As each mattress type in Sealy’s collection comes in a range of firmness settings, sleepers with any body type should be able to find a combination that suits their needs, with multiple firmer options available for heavier individuals.

In the same way, the wide variety offered by Serta’s Perfect Sleeper mattress collection should provide a firmness and construction combination to suit any body type and weight very well.

Sealy vs. Serta Temperature Regulation

When it comes to sleeping cool, both the Serta Perfect Sleeper and Sealy Posturepedic collections do a pretty good job of preventing heat retention. However, if you are particularly concerned about overheating at night, you should consider choosing a Serta or Sealy innerspring or hybrid mattress. These mattresses have more breathable structures, which means heat can escape more easily. Memory foam mattresses, one the other hand, tend to retain heat more readily, which could be a good thing if you sleep cold.

The Sealy Posturepedic range features various sleep technologies that help it to sleep cool. Firstly, all Posturepedic mattresses come with a Moisture Protect cover. This cover is made from a cooling, breathable material and can wick away moisture during the night. If sleeping cool is one of the most important factors to you, you should consider the Premium hybrid mattress. This model features Sealy Chill Technology to create a cooling sleep surface, and it also has an open-cell comfort layer to make the beds more breathable and prevent heat retention.

However, if you want to sleep as fresh as possible, the Serta Perfect Sleeper range might just pip Sealy to the post. Sealy has specially engineered the Perfect Sleeper range with temperature regulation in mind, and the manufacturer describes Perfect Sleeper mattresses as ‘designed to breathe.’

Serta mattresses are cool because they contain Cool Twist Memory foam in the comfort systems. This material includes cooling gel particles that can wick away heat during the night. This feature combines with a highly breathable stretch knit cover to provide an unusually cool sleeping experience.

Serta vs. Sealy Sleep Trial and Warranty Information

All Sealy Posturepedic mattresses come with a 10-year limited warranty, which is around the standard length in the mattress industry. This warranty entitles you to have your bed repaired or replaced if you discover a manufacturing error. Serta Perfect Sleeper mattress warranties, on the other hand, vary in length according to which model you select. Serta mattress warranties last for a maximum of 20 years. You should check the code on the law tag attached to your mattress to find out the warranty length of your product.

When it comes to sleep trials, Serta Perfect Sleepers come with a better offer. All mattresses in this range are covered by Serta’s 45-day Comfort Assurance Program. Although this means that you can return your mattress for any reason for a refund within the trial period, bear in mind that there is a 30-day settling in period attached to the trial.

So, you must sleep on your new mattress for at least 30 nights before returning. It’s also important to note that you will have to pay a fee equal to 15% of the mattress’ value for handling and disposal, and a flat $200 shipping charge. While this sleep trial is on the shorter side in comparison to many other brands and return fees are relatively steep, Sealy does not offer any sleep trial on its Posturepedic mattress range at all.

Sealy Posturepedic vs. Serta iComfort

While the Serta Perfect Sleeper range is the most comparable with Sealy’s Posturepedic range, you may also wish to consider Serta’s iComfort mattress. This all-foam mattress features layers of carbon fiber memory foam with cooling gel memory foam. This combination allows the mattress to conform closely to the shape of your body without overheating, as it contains gel particles that can wick heat away during the night. The mattress has a medium feel which should feel comfortable for most people but is especially suitable for side sleepers.

So, is the Serta iComfort mattress or the Sealy Posturepedic range better? The answer to this really depends on your preferences. If you want a wide range of construction and firmness options to pick from, the Posturepedic range is undoubtedly your best bet. However, there are currently no medium mattresses in the Posturepedic range. If you know that a medium mattress suits you best and want the conforming benefits of gel memory foam, the Serta iComfort mattress should suit your needs well.

Which Mattress Should I Choose?

Now that you understand everything there is to know about Sealy Posturepedic vs. Serta Perfect Sleeper mattresses, it’s time to answer the all-important question- should I choose a Sealy or a Serta mattress for my bedroom? The answer will come down to various factors, including your sleeping style, comfort preferences and which features you value most in a mattress. To make choosing between a Sealy and Serta mattress a little easier, here is our expert’s rundown on which mattress will best suit which sleeper.

Choose a Sealy Posturepedic Mattress if:

  • You want a mattress to relieve back pain

The key standout feature of Sealy’s Posturepedic range is the additional lumbar support contained in each one of its mattresses. This reinforcement gives added support to your lower back and core region, which can help to correct poor sleeping posture and encourage a healthier spinal alignment. Therefore, a Sealy Posturepedic mattress could be helpful if you need a bed that can help combat back pain and discomfort at night.

  • You want plenty of options

The Sealy Posturepedic range has an unbelievable amount of choice available, and it includes innerspring, memory foam and hybrid options. Each mattress type is also available with various options in terms of features and a choice of firmness settings. This variety means that there should be a Sealy Posturepedic mattress to suit all tastes, sleeping positions and body types.

  • You want strong edge support

All Sealy Posturepedic mattresses come with reinforced edges, although the method varies depending on the model you choose. More robust edge support has various advantages, probably the most important being that it increases durability and reduces sagging. However, additional edge support also increases the amount of surface area you can actually lie on, letting you lie or sit right up to the edge without damaging the mattress or experiencing a roll-off effect.

Choose a Serta Perfect Sleeper Mattress if:

  • You want to sleep cool

Although both brands perform relatively well when it comes to combatting heat retention, the Serta Perfect Sleeper range is particularly adept at keeping you cool and comfortable. Its innerspring mattresses have a highly breathable structure, while the memory foam and hybrid models make use of gel-infused memory foam to wick excess body heat away while you sleep.

  • Choice is important to you

Like the Sealy Posturepedic range, you should find that you have plenty of options available when you shop from the Serta Perfect Sleeper mattress collection. It contains a wide range of innerspring, memory foam and hybrid mattresses in various firmness settings, so you should be able to find a bed that suits you well.

  • You share your bed with a partner

Serta Perfect Sleeper mattresses perform exceptionally well when it comes to motion isolation. This means that you shouldn’t be able to feel each other’s movements from the other side of the bed, even if one or both of you tosses and turns at night. This all adds up to less sleep disturbance and a higher quality of rest.

The Bottom Line

Hopefully, this Sealy and Serta beds review article has helped you to decide whether one of these brands could be the right choice for your next mattress purchase. Both provide consumers with a vast number of options and firmness settings, whether you’re looking for an innerspring, memory foam, or hybrid mattress. However, despite their similarities, it’s the differences between the brands that will help you to decide between them. It’s impossible to say that either Sealy or Serta is the ‘better’ mattress brand, as which you prefer comes down to personal taste and your sleep needs.

Buying a mattress is a significant financial investment and one of the most important purchases you can make to improve your sleep quality and overall wellbeing. The best way to make sure you’re getting the best mattress possible is to read unbiased mattress reviews.
