Sealy 12-Inch Memory Foam Mattress Review
Sealy has been in the business of making mattresses for over 130 years. Founded in Texas, the company started out with mattresses made for the founder’s friends. Since then, millions of consumers have enjoyed the superior comfort and reliable support of Sealy mattresses.
The brand was acquired by Tempur-Pedic International in 2012 to form Tempur Sealy International, Inc. Sealy mattresses continue to be built in the US, each mattress exceeding industry standards to deliver long-lasting comfort and support.
Sealy offers three types of mattress: memory foam, innerspring, and hybrid mattresses. The Sealy 12-Inch Memory Foam Mattress with Adaptive Comfort Layers is the brand’s thickest all-foam mattress. It features adaptive memory foam, responsive comfort foam, and high-grade conventional foam to give sleepers a supportive mattress with a medium-firm feel. A removable cover also helps the mattress last longer and makes cleanup easier.
Material and Construction
The Sealy 12-Inch Memory Foam Mattress with Adaptive Comfort Layers is designed to give you the comfort and deep support you need for a restful night of sleep. The mattress offers 3 types of foam to keep you as comfortable as possible in bed.
This Sealy mattress has three foam layers: on top is a 3-inch layer of premium adaptive memory foam, in the middle is 4 inches of responsive comfort foam, and at the bottom is 5 inches of high-grade conventional foam. All these different foam layers work together to provide complete, all-body support so you can wake up pain-free.
The topmost layer of this 12-inch Sealy mattress features premium adaptive memory foam. What makes memory foam unique from other types of foam is its construction. Unlike other types of foam, memory foam has an open-cell structure. The open cells give memory foam the ability to adjust to the shape of the object on its surface and spring back into original shape once the pressure is removed. This means the mattress’ surface will readily accommodate your body’s contours once you lie in bed, then go back to its original shape once you get up.
The premium adaptive memory foam in this Sealy mattress is capable of forming around your body, remembering your unique shape. This helps relieve pressure and provide maximum comfort, especially in pain points like the back and joints. Plus, the layer itself is three inches thick, which is thicker compared to the memory foam layers on other mattresses today. This means you’ll really feel the comfort brought by the memory foam in this mattress.
What’s unique about the memory foam layer in this Sealy mattress is that it’s a high-density memory foam. This mattress’ memory foam layer has a density of more than 5 pounds per cubic foot. The memory foam itself usually has smaller cells compared to lower-density foam, so it may be slower to respond or adjust to your body’s shape. High-density memory foam brings a number of benefits compared to low-density memory foam. This type of memory foam is sought-after for its ability to offer unparalleled support and durability.
The middle layer of the Sealy 12-Inch Memory Foam Mattress with Adaptive Comfort Layers is made from 4 inches of responsive comfort foam. This layer of comfort foam is also designed to follow your body’s contours. It’s slightly firmer than the top layer of memory foam, and it prevents you from sinking into the mattress. This way, you won’t feel suffocated by the mattress’ foam layers. The layer of responsive comfort foam also serves as a functional transition layer between the top layer of memory foam and the base layer of high-grade conventional foam.
The mattress is thickest at its base layer, which includes 5 inches of high-grade support foam. This layer of foam is designed to provide both comfort and support. For this mattress, the layer of support foam serves as a sturdy base that gives the mattress its structure, giving the mattress enough firmness for sufficient lumbar support. The base layer also helps encourage airflow throughout the mattress.
The three layers of the Sealy 12-Inch Memory Foam Mattress with Adaptive Comfort Layers are wrapped in a comfort cover. The cover is made from a soft, circular knit fabric that improves comfort by giving you a plush surface to rest on. This mattress’ cover is removable, too, to make the mattress easier to keep fresh and clean.
The layers in this Sealy 12-Inch Memory Foam Mattress in a Box are made from CertiPUR US-certified foam. This means the foam in this mattress is free from toxic or hazardous substances, like heavy metals, ozone depleters, and regulated phthalates. The foam in this mattress is also certified to be low in VOC emissions, which helps preserve the quality of indoor air in your home.
The mattress is rolled and compressed into a box before it’s shipped out to consumers. All you have to do upon receiving your mattress is unbox and unroll it onto the base. The mattress may need up to 24 hours to fully expand.

Comfort and Ergonomics
The Sealy 12-Inch Memory Foam Mattress with Adaptive Comfort Layers is one of the most comfortable mattresses you can get today. The mattress offers three different types of foam to ensure that you’re as comfortable as possible. Plus, the mattress’ cover gives the mattress a soft, plush feel you’ll enjoy.
This Sealy mattress comes with a cover that’s made from circular knit fabric. Circular knit fabric offers a variety of benefits, not the least of which is a soft texture. The softness of the mattress’ cover makes it comfortable to rest on, so you can immediately relax as soon as you lay in bed. The knit fabric cover also gives the mattress some flexibility, while adding some breathability. This is important especially because memory foam can run slightly hot for some sleepers.
Just past the cover, you’ll immediately feel the memory foam layer of this Sealy mattress. The mattress’ top layer is made from premium adaptive memory foam, so you can be sure that it will cradle your body and relieve pressure in various areas of your body. Memory foam is designed to be flexible enough to adjust itself according to your body’s unique shape. It will yield around your body, rather than forcing your body to adjust to the mattress’ surface.
One of the best features of memory foam is that it can easily mold itself to your contours, however needed. This means the mattress will be better at relieving pressure on your body compared to other materials. The memory foam won’t push back or place upward pressure on your body as you lay in bed.
The mattress’ layer of premium memory foam is also designed to support proper alignment of the back. Memory foam does this by ensuring even weight distribution across the mattress. The memory foam compresses where it’s needed most to keep your spine in proper alignment and support your lower back.
For side sleepers, for instance, the shoulders and hips bear the most weight. The memory foam layer in this Sealy mattress compresses under the shoulder and hips to ensure that your lower back gets adequate support and your spine is properly aligned. This way, you can wake up without lower back pain and muscle tension.
The high density rating of the memory foam layer also makes the mattress more effective at pressure relief. According to sleep experts, high-density memory foam is also more efficient at improving circulation.
This Sealy mattress also provides sufficient comfort and support for all sleeping positions. The memory foam in this mattress accommodates your body’s shape, whether you sleep on your stomach, side, or back. This way, you can settle into your favorite position without developing pressure points.
The middle layer of responsive comfort foam in the Sealy 12-Inch Memory Foam Mattress with Adaptive Comfort Layers also contributes to the overall comfort provided by the mattress. The 4-inch middle layer is designed to be responsive enough to prevent sinking, so you won’t feel smothered by the mattress’ memory foam layer. This also makes it easier for you to get out of bed when needed.
The layer of responsive comfort foam also helps cut down motion transfer, so you won’t wake up if your partner tosses and turns all night. This is an excellent benefit for both light sleepers and restless sleepers.
The base layer on this Sealy foam mattress keeps you comfortable by providing consistent support throughout the night. With the thickness and density of foam in this layer, you’ll get that “on-the-bed”, floating feel for maximum comfort. The 12-inch thickness of the mattress itself also helps it provide more pressure relief. The extra thickness of the mattress also allows it to comfortably accommodate additional weight.
The memory foam in this Sealy mattress also makes it more comfortable to use through its allergen-repellent properties. The dense structure of memory foam limits the growth and spread of dust mites. Other allergens such as mold and pet dander will also be unable to work their way through the foam layers of this Sealy mattress.
And since the foam layers in this mattress are CertiPUR-US certified, you can be sure that this Sealy mattress won’t emit any harmful or chemical odors that can trigger allergies or cause other health problems. For your safety, the mattress is made without heavy metals, formaldehyde, regulated phthalates, and ozone depleters.
