Sealy 13-Inch Plush Eurotop

Sealy offers multiple lines mattresses from Shop Cocoon, Innerspring, Memory Foam, to Hybrid mattresses. Each mattress comes in different sizes and firmness. But for this post, we’ll focus on the conform line which offers Memory Foams like Sealy Conform Premium Mattress (Plush).


This mattress contains multiple materials which have a total of 5 layers. For its outer layer, it has the Ultra-Stretch ComfortLoft cover with chill material. Its fabric with mid-loft knit is super stretchable and feels cool to the touch to help you sleep better. Under its cover, it has the exclusive material from Sealy known as the SealyChill Gel Memory Foam. This 2 inches foam is specifically designed with 3-Zone and PCM gold. Thus, its gel can help the foam to adapt to your body shape and size. Next to this layer is the 2 inches SealyCool Gel Memory Foam which is another layer of conforming foam. Of course, it is also infused with gel beads to make them more flexible and durable for support. Underneath this layer is the 3 inches ComfortSense Gel Memory Foam which is considered as the latest innovation among gel memory foams. ComfortSense Foam is designed to respond according to your unique body shape to ensure your comfortable sleep every night. Its last layer is the SealySupport Gel Base Foam which is 6 inches thick. This final layer provides a high-quality supportive feel with firmer foam. Overall, this memory foam has 13 inches thick profile which is available in different sizes. Depending on your size and your partner’s (optional), you can get it in Twin Long, Full, Queen, King, and California King sizes.


This Sealy Memory Foam comes in plush and cushion firm feel. Focusing on the plush version, this mattress comes in thicker SealyChill Gel Memory Foam. It also has a thicker Sealy ComfortSense Gel Memory Foam which allows it to provide a plush feel.

Temperature Regulation

This plush version of the Sealy Conform Line consists of multiple layers that keep it cool all night. First, it has a stretchable cover that is made with chill cooling technology which makes its fabric cool to the touch. Next to this are its SealyChill Gel Memory Foam, SealyCool Gel Memory Foam, Sealy ComfortSense Gel Memory Foam, and SealySupport Gel Base Foam. In other words, all materials of this Sealy Conform Premium Mattress are made with the latest cooling technology. Therefore, you don’t have to worry about sweating at night even if you’re a hot sleeper. Its gel-infused memory foams will cushion your body to get rid of excess heat from your body for a cool sleep


This plush version has a thinner foam base compared to its cushion firm version. However, Sealy designed it to provide targeted support just where you need it. This is thanks to its Posturepedic Technology which the company developed with the aid of orthopedic specialists. It targets the heaviest parts of your body to provide reinforced support. At the same time, the Posturepedic Technology uses a top layer that has a denser feel in the middle area. Thus, your body stays leveled to ensure the health of your spine while you sleep. No need to worry that the middle area will sag.

Serta Mattress

Best For:

  • Memory foam lovers who want more edge support
  • Stomach, back, and combo sleepers with a small, medium frame
  • Side sleepers with large frames
  • Anyone who needs more temperature regulation solution
  • Customers who prefer shopping either online or at brick-and-mortar stores

Serta Raised Air Mattress with Never Flat Pump

Just like Sealy, Serta offers multiple models in its online and physical stores. It got the Perfect Sleeper, iComfort, Mattress in a Box, Hotel Mattresses, SleepTrue, and other mattress models. However, we’re going to focus on one mattress only from its Perfect Sleeper line which is the Express Mattress.


If the Sealy mattress has a thick 13 inches profile, this Serta Perfect Sleeper only has a thinner profile. This consists of 4 layers which include its Breathable Knit Cover with CoolFeel technology. Under this is the exclusive Serra Premium Gel Memory Foam which has a body-conforming capacity as the first comfort layer. Its second comfort layer is the Serta Gel Infused Support Foam which provides additional cushioning comfort. For its support system, this Perfect Sleep Express has the Serta Foam Core which completes its 12 inches profile. Just like the Sealy mattress, this Express Mattress is also available in different sizes. These sizes include the Twin, Full, Queen, and King sizes.


Compared with the Sealy mattress, this 12 inches version is available in a firm feel only. It suits light to average weighted back, stomach, and combo sleepers. Since it is a firm pure memory foam mattress, it might not feel that comfortable for side sleepers with a small frame. But if you’re a little heavy, its firmness might feel slightly softer even if you sleep on your side.

Temperature Regulation

This Serta Perfect Sleeper Express contains multiple layers with cooling technology. Its Premium Gel Memory Foam helps reduce the excess heat from your body as the mattress sleep surface. Its Gel Infused Support Foam also reinforces the top layer to get rid of heat from the mattress. This Perfect Sleeper Express Mattress even has a CoolFeel cover that is more breathable than other regular mattress covers.


When it comes to playing the role of support, this mattress has a thick Serta Foam Core to ensure that. This layer reinforces its previous layers to keep your full-body support while you’re sleeping. One of the best things about its support system is its offered edge support. Thus, you can feel safer even when you’re lying near the edge of the bed. Despite being a bed-in-a-box mattress, its supportive capacity is guaranteed after its hassle-free setup.


For the highlight of this post, let’s get down to their differences. So, let’s start with the price department which is pretty easy to differentiate. For the Sealy mattress, its prices range from $2,274 (Twin Long) to $2,799 (King and California King). Meanwhile, the Serta mattress’ prices range from $699 (Twin) to $1,099 (King). Whether you’re looking for an affordable mattress or expensive mattress, this guide can help you which one to pick. When it comes to sizes, Serta’s smallest size starts with the Twin size while Sealy starts with the Twin Long size. If you want a mattress that is bigger than a King size, you can rely on Sealy since it is also available in California King size. If you want a brand that offers more firmness options, you can also rely on Sealy when it comes to that. It’s available in a plush and cushion firm while Serta is available in a firm feel only.

If you’re buying a mattress for you and your partner, the edge is one of the most important things to consider. In this case, the Serta mattress has more edge than the Sealy mattress since it consists of firmer pure memory foams.


Still can’t decide whether it’s Serta or Sealy? No worries. Here are some guide questions that can help you make your final verdict:

How much is your budget?

If your budget for a premium mattress is less than $1,000 only, it is pretty obvious that Serta is your best option. But if you’re fine with spending over $2,000 even for a Twin Long size mattress, Sealy is a great investment.

Are you a hot sleeper?

Both mattresses contain materials that can handle the heat. However, the Sealy mattress contains more high-quality materials that can keep you cool throughout the night.

Do you share your bed?

Size is very important when you share your bed. Thus, this is where Sealy’s California King sized-bed can come in handy to accommodate sleepers with small to large frames. But when it comes to the edge support, we recommend Serta due to its firmer feel, especially on the edge.
