Overview of the Sealy Memory Foam Mattress

With well over 100 years in business, Sealy is one of the most-recognized names in mattresses. Sealy makes an extensive number of mattress types and models, and these are all sold through third party retailers.

Though most well-known for its innerspring mattresses, Sealy has also started producing its Conform line, which features memory foam mattresses. The Conform line is broken into 3 collections: Essentials, Performance, and Premium.

Some of the key strengths of the Sealy memory foam mattresses include:

  • Numerous mattress choices: with three collections and several models within those collections, Sealy mattresses are available in many heights, designs, firmness levels, and price points. There is no shortage of choices for customers who want a Sealy mattress.
  • Established brand name: while many online mattress companies are less than a few years old, Sealy has a long history of designing and manufacturing mattresses.

Potential drawbacks for the Sealy memory foam mattresses include:

  • Reliance on third party sales and support: Sealy does not sell mattresses directly and instead relies on independent retailers. As a result, both sales and support come primarily from the retailer. This can lead to significant variance in product availability, pricing, and return policies for Sealy mattresses.
  • Unknown mattress specifications: Sealy does not disclose information about things like the density or specific composition of its foam layers. Limited details on the specifications reduces our ability to fully evaluate the mattress materials and also circumvents effective comparison shopping.

In addition to the Conform line, Sealy also offers innerspring and hybrid mattresses. You can follow these links to find our reviews for their other two other product lines — the Response (innerspring) and Hybrid lines.

About the Sealy Memory Foam Mattresses


Sealy Memory Foam Mattress Specifications

The specifications for each Sealy memory foam mattress depends in large part on which collection it is a part of. The table below describes the main design characteristics for each collection.

Mattress Collection Standard Design
Essentials Cover: basic knit cover
Top layer: gel-infused memory foam (Sealy ComfortSense Foam)
Bottom layer: gel-infused polyfoam (SealySupport Gel Foam)
Performance Cover: knit cover with moisture wicking properties
Top layer: gel-infused memory foam (Sealy ComfortSense Foam)

The Performance and Premium collections both include Sealy Posturepedic technology. This refers to the inclusion of additional foam to reinforce the center portion of the bed. The concept is to offer additional support to the part of the bed that is underneath the heaviest parts of your body.

Sealy does not publish the density or other specifications for these foam layers. This can make it harder to comparison shop or to truly understand the composition of the mattress.

Where It’s Made

The Sealy memory foam mattresses are manufactured in the USA.


Buying Logistics

Where to Buy

The Sealy memory foam mattresses are sold primarily in brick-and-mortar mattress stores. Some of these brick-and-mortar stores may also offer Sealy memory foam mattresses on their websites; however, availability and pricing online can vary significantly.

Sleep Trial / Refunds

Sealy does not offer any specific sleep trial. Any return policy will be determined by the third party retailer from whom you buy the mattress. Some retailers may offer 30- or 60-day return policies while others may not offer returns at all. It is essential to ask about the return policy prior to purchase and to make sure that you have these details in writing.


The cost, speed, and type of delivery of a Sealy memory foam mattresses depends on the retailer that it is purchased from. Some retailers may offer setup and installation as well as haul-away of an old mattress.


Most Sealy memory foam mattresses come with a 10-year limited warranty that covers defects in materials and manufacturing. Full warranty details are available at http://www.sealy.com/warranty-service/between-2014-to-present, and you can ask the retailer for the specific warranty details for any individual mattress.

Customer Service

Because Sealy does not sell their mattresses directly, they are not the first line of support for customers. Instead, customers usually must deal with the retailer who they bought they mattress from. Because of this, it is important to only buy a Sealy mattress for a store that you trust and that has a quality reputation for customer service.

The Sealy company itself has been in business since the late 19th century and is one of the best-known brand names in the bedding industry. Sealy has an A+ rating from the Better Business Bureau. In 2013, Sealy was acquired by Tempur-Pedic.


Mattress Performance

Each of the models that are part of the Essential, Performance, and Premium collections include gel-infused memory foam comfort layers and gel-infused polyfoam base layers. However, the exact design, including the thickness of the layers, the density of the foams, and the internal mattress design can all vary significantly. These differences are likely to create sizable disparities in performance and durability between different Sealy memory foam mattresses.


The Sealy memory foam mattresses all rely on the contouring effect of memory foam to provide support. By responding in proportion to the weight and pressure that is applied, memory foam can help to offer support where it is most needed. In practice, this means that the spine is aligned properly, reducing the risk of back pain.

Mattresses with very thin or low-quality memory foam comfort layers are less likely to effectively provide this kind of support. This is because the foam may not be strong enough to adequately conform the pressure, and this issue can be more acute for people who weigh over 230 pounds or who have very pronounced pressure points.


There is limited long-term data regarding the durability of the Sealy memory foam mattresses. In situations without long-term data, we ordinarily evaluate the likely durability of mattress based on its internal components and the quality of the materials. Because Sealy shares only limited information about its foams and their composition — in particular the thickness and density of the foam layers — we are not able to draw firm conclusions about the expected durability of these mattresses.


There are many firmness options available for each of the mattress lines. The Essential and Performance collections have offerings in Plush (3-4 on the typical firmness scale), Cushion Firm (5), and Firm (6-7). The Premium collection comes in Ultra Plush (2-3) and Firm (6-7) models.

Motion Transfer

Memory foam mattresses have excellent motion isolation properties. Because the foam only responds to the part of the body where pressure is applied and then slowly recovers to its original shape, movement on one part of the mattress is rarely felt on other parts of the mattress.


Almost all foam mattresses have some odor when they are first unboxed. Reports from customers have indicated that Sealy mattresses tend to have more odor than other brands. These odors are not harmful, though, and usually dissipate within a few hours to a few days.

Sleeping Hot

The contouring effect of memory foam can cause a person to sink deeply into the mattress, limiting airflow around the body and causing the mattress itself to retain heat. Infusing the foam with gel is one method of trying to prevent heat retention, but studies are mixed about whether it actually has this effect.


Like most memory foam mattresses, these options from Sealy may cause some slight interference to sexual activity. This can happen because of the way that memory foam can inhibit motion, which can occur when people feel that they are sinking too deeply into the mattress. While this isn’t a major issue for most people, it is something to be aware of as a potential concern for memory foam.
