Available in white, the Sealy Response Performance is a 14-inch traditional innerspring mattress that offers excellent support and comfort. One of the striking features of this mattress is Posturepedic technology.

This innovation targets the heavy parts of your body and pressure points to offer proper support and pressure relief. This is an innovation designed by Sealy Posturepedic in conjunction with top orthopedics.

Inside this mattress, there are two layers: the comfort layer and the support layer. There is a solid fabric-encased coil base and reinforced coil border on the perimeter. It responds to every move, ensuring that your mattress conforms to your curves. These coils also enhance motion isolation and give the mattress that bouncy feel.

Available in 6-inches and 8-inches, this mattress is very affordable and guarantees excellent value for money. It also offers excellent pressure relief, support, and a calm night of sleep, courtesy of its cooling properties.

As the name suggests, the Sealy mattress has been created using conventional foam. The support layer consists of denser foam for maximum body support and durability.

The 8-inch foam mattress comes with Copperchill, Sealy’s unique innovation that uses Copperchill fused memory foam to enhance cooling. If you sleep hot, buying a Sealy mattress with Copperchill should be a priority.

Inside this mattress, there is a 6-inch ultra-support foam for support and durability.

When it comes to the comfort layer, the Sealy 8-inch Copperchill Mattress has a 2″ premium response memory foam fused with Copperchill. This mattress is ideal for all types of sleepers, whether stomach, side, or back sleepers. Just make sure that you are not so heavy. This is considering the mattress is only 8-inches thick.

4. Sealy Copperchill Hybrid Mattress

Another good Sealy mattress for hot sleepers is the Sealy 12-inch Copperchill. This is simply because its comfort layer has foam with infused Copperchill, an element that promotes cooling.

Unlike the Sealy Copperchill Foam Mattress, this one is an innerspring mattress, otherwise known as a hybrid mattress.

Inside this mattress, there are 8-inch pocketed coils that provide adequate support at the center of the mattress, and the edges. The coil springs contour around your body curve perfectly, targeting support to all the pressure hotspots.

As for its comfort layers, there is a 0.75-inch premium response memory foam alongside a 1-inch advanced comfort foam. This combination ensures maximum conformity and pressure relief for a peaceful night.

The 10-inch and 12-inch variants are available in five sizes (Twin, Twin XL, Full, Queen, King, and California King). The firmness for all models is medium-firm.

Is Kingsdown a Good Brand?

Kingsdown logoKingsdown is a great mattress brand that promises comfort, support, and durability. There is a wide range of Kingsdown mattresses, from traditional foam mattresses to innersprings.

Kingsdown is a top-of-the-shelf mattress brand that is part of Owen & Company Limited. For over a century, the company has excelled in manufacturing and distributing high-end mattresses crafted using state-of-the-art technology and innovation.

1. Kingsdown Passions Imagination

The Kingsdown Passions Imagination Queen is a hybrid mattress that combines foam and innersprings for the comfort and support layers, respectively.

Interestingly, the company also offers matching 9-inch box springs to go with the different mattress sizes. You can trust the Passions Imagination with your comfort if you are a hot sleeper, stomach, combo, back, or side sleeper.

The Kingsdown Passions Imagination Pillowtop comes with 904 (Q) Tri-Zoned 15-gauge individually-wrapped innerspring coils.

The above review is for the Kingsdown Passions Imagination Pillowtop. There are six sizes available (Twin, Twin XL, Full, Queen, King, and California King).

2. Kingsdown Passions Aspiration

Another best-selling Kingsdown mattress is the Kingsdown Passions Aspiration, also an innerspring mattress.

Here again, Kingsdown has done a wonderful thing to accompany some packages with the semi-flex 9-inch box springs.

Get this mattress if you are a heavy sleeper, back sleeper, combo sleeper, hot sleeper, a couple, or sleeper with back pain.

Inside the support layer, there is no difference between the Kingsdown Passions Aspiration vs. Kingsdown Passions Imagination. The American brand also included 904 (Q) Tri-Zoned 15-gauge individually-wrapped innerspring coils that contour around all your body curves offering targeted support. However, for the comfort layer, this mattress comes with firm specialty foam and gel-infused foam for pressure relief and heat dissipation.

3. Kingsdown Passions Aspiration PT

Third, in the list of the best-selling Kingsdown mattresses is the Kingsdown Passions Aspiration PT. This one is an innerspring mattress that combines coil springs and memory foam for the support and comfort layers.

Like the other Kingsdown mattresses in this review, the Passions Aspiration has packages that tag along with semi-flex 9-inch box springs. The mattress is ideal for hot sleepers, stomach, combo, back, or side sleepers.

Under the hood, the Passions Aspiration PT comes with the same coil structure used in the other Kingsdown mattresses. These are 904 (Q) Tri-Zoned 15-gauge individually-wrapped innerspring coils for optimizing contouring and support.

As for the comfort layer, things take a little twist. The company included gel-infused memory foam and plush foam for maximum conformity and pressure relief.

4. Kingsdown Passions Fantasy

The mattress is ideal for the heavy sleeper, back sleeper, combo sleeper, hot sleeper, a couple, or sleeper with back pain.

Kingsdown included 744 (Q) Tri-Zoned 14.5-gauge individually wrapped innerspring coils for support and body contouring inside the support layer. On the other hand, the comfort layer includes gel-infused memory foam combined with firm foam to enhance body-hugging and pressure relief.

Kingsdown vs. Sealy Face to Face Comparison

Now, onto the main business of the day, how does Sealy compare to Kingsdown? To understand how these two brands compare, we will assess all the crucial aspects that buyers consider when choosing the best mattress to buy.

These include comfort, support, firmness, cooling and temperature regulation, motion isolation, eco-friendliness, shipping and delivery, and, importantly, aftersales (sleep trials, warranty, and returns). Without further ado, let’s get into it.

Is Kingsdown More Comfortable Than Sealy?

One of the crucial factors to consider when shopping for a mattress is comfort. You want a mattress with a comfort layer that hugs your body and offers targeted pressure relief.

So, how does Sealy compare to Kingsdown in terms of comfort?

Are Kingsdown Mattresses Comfortable?

Kingsdown Mattresses Comfortable
From the construction as well as customer reviews, Kingsdown mattresses are comfortable. Out of 10 ratings, we give it an 8.7. The prominent attribution for this mattress’s comfort is the materials used on the comfort layer.

Kingsdown Passions Imagination and Kingsdown Passions Aspiration both come with gel-infused memory foam that hugs your body and relieves all pressure points. On the other hand, the Kingsdown Passions Aspiration uses gel-infused memory foam and plush foam to enhance comfort further.

Are Sealy Posturepedic Mattresses Comfortable?

Coleman SaluSpa Portable
Yes. Sealy mattresses have been designed to offer excellent comfort. As a matter of fact, Sealy has better ratings compared to Kingsdown.

Our experts gave it an 8.9, making it the winner as far as comfort is concerned.

The company relies on premium materials such as advanced comfort foam, premium response memory foam, and advanced comfort foam.

Which Mattress Has the Best Support?

Besides comfort, support is also an important consideration. This is the ability of the mattress to float your body while keeping the spine aligned throughout the night. Without a bed with good support, you will constantly wake up with neck pains, back pains, etc. It’s also essential to ascertain the mattress’ edge support.

Let’s compare the support of mattresses offered by these two mattress brands.

Kingsdown Mattress Support

Kingsdown Mattress Support
All the Kingsdown mattresses in this comparison review are hybrid. As you may be aware, the coil springs used in these mattresses offer the best support. Kingsdown mattresses have good customer reviews regarding the support they offer.

The Kingsdown Passions Imagination and Kingsdown Passions Aspiration are both innerspring mattresses with 904 (Q) Tri-Zoned 15-gauge individually-wrapped innerspring coils which offer solid support. What’s more? They are very responsive to contour around your body perfectly.

As for Kingsdown Passions Fantasy, the coil structure is not as robust. Here the company used 744 (Q) Tri-Zoned 14.5-gauge individually-wrapped innerspring coils. Remember, the more the number of coils and the higher the gauge, the better the support. As for edge support, Kingsdown is also a good choice. It comes with a full-body surround edge support that doesn’t sag whatsoever, unlike ordinary mattresses.

On a scale of 10, our experts gave Kingsdown a cool 9.2 when it comes to support

Sealy and Sealy Posturepedic Support

Sealy Support
Like Kingsdown, Sealy boasts excellent support, according to online reviews and the construction of the support layers in its mattresses. There are innerspring hybrid mattresses that combine coils and foam and foam mattresses that use foam only in the comfort and support layers.

Sealy Conventional Foam Mattress and Sealy 8-inch Copperchill Foam Mattress are no match for Kingsdown when it comes to support. These are foam mattresses that are known to dip and sag faster. They don’t have the resilience of innerspring mattresses. The edge support is also not as durable as that of innerspring mattresses. We also rated Sealy 9.2.

The latter wins the bout in the battle between Sealy Copperchill Hybrid Mattress vs. Sealy Response Performance Mattress. While both mattresses offer excellent support courtesy of the coil support, Sealy Response Performance comes with Posturepedic technology. This innovation leverages ultra-firm support layers and targeted support where you need it most, with pinpoint accuracy.

As for edge support, there is a lot of improvement between Sealy Copperchill Hybrid Mattress vs. Sealy Response Performance. When it comes to edge support, these two mattresses are superb, but the Sealy Response Performance is the best courtesy of the reinforced coil border.

Understanding Firmness

Firmness is an important consideration when buying a mattress. For starters, this is the feel of the mattress when you lie on it. It could be plush, soft, firm, or stone hard. Make sure the mattress you buy has the right firmness. For the record, there is no such thing as the best firmness. What can be comfortable for me may not necessarily work for you. In the below table, we have assessed the firmness levels to help you with your shopping.

Cooling and Motion Isolation

Besides comfort and support, there are other mattress features that determine whether you will have a comfortable and sound sleep or not. These include cooling and temperature regulation and motion isolation.

Which is the Best Mattress for Hot Sleepers

Copperchill for Hot Sleepersn
For hot sleepers, a mattress with a cooling effect is paramount. This is especially during the hot summer nights when you sweat a lot. For the record, mattresses are not fans, so don’t expect magic if you are a hot sleeper. But there are a few technologies that mattress companies leverage to enhance cooling and mattress freshness. So, how does Kingsdown compare to Sealy in terms of cooling and temperature regulation?

Kingsdown is a good mattress for thermal regulation, but not the best that there is.

The American brand uses perforated gel memory foam that allows for excellent airflow and circulation in and out of the mattress.

The breathability of the foam allows you to at least sleep cool if you are a hot sleeper.

On the other hand, Sealy mattresses vary when it comes to cooling. The Sealy Conventional Foam Mattress, for example, doesn’t have any bells and whistles regarding cooling. Sealy Copperchill Hybrid Mattress and Sealy Copperchill Hybrid Mattress, on the other hand, sleep cool courtesy of the Copperchill fused memory foam.

As you may be aware, Copperchill boosts cooling and temperature regulation.

Which is the Best Mattress for Sleepers Who Toss and Turn?

Sleepers Who Toss and Turn
Sleepers who toss and turn frequently can make the other sleeping partner uncomfortable because of the noise and ripple effect when the mattress compensates for the pressure during tossing and turning. That said, it’s essential to go for mattresses with effective motion isolation. This way, you can put up with a partner that tosses and turns.

So, which of the two brands is the best here?

Kingsdown Motion Isolation
Kingsdown mattresses are hybrid, so they are the best for motion isolation.

Interestingly, the three mattresses in this review have responsive Tri-Zoned individually-wrapped innerspring coils that absorb all the pressure and isolate motion so you can sleep soundly.

Sealy Motion Isolation
As for Sealy, the memory foam mattresses, Sealy Conventional Foam Mattress and Sealy Conventional Foam Mattress, and Sealy 8-inch Copperchill Foam Mattress have poor motion isolation as they are made using foam. But the Sealy Copperchill Hybrid Mattress and Sealy Response Performance Mattress do better as they have responsive coils inside them, which dissipate motion.

Which Brand is Eco-Friendly?

Sleepers Who Toss and TurnThe manufacture of mattresses takes a toll on natural resources. Its carbon footprint is also a great threat to the ozone layer.

What’s more? Most old mattresses end up in landfills, and equally is an environmental concern. If you are conscious about the environment, you should buy from an eco-friendly brand.

Kingsdown mattresses are eco-friendly as they are made using eco-friendly and all-natural options. No chemicals used in the manufacture pose a threat to the ozone layer. The products from this brand come with top eco-friendly certifications such as CertiPUR-US. Unfortunately, the company won’t dispose of your mattress like many brands such as Casper, Sealy and Beautyrest do.
Sealy also is an eco-friendly mattress brand that manufactures its products with recyclable material. The company claims that over 90% of all raw materials are recyclable. As mentioned above, Sealy will pick your old mattress for proper disposal. That tells you the company is committed to reducing the volumes of mattresses ending up in landfills.

Shipping and Delivery

When purchasing a mattress, don’t just look at the comfort features; also assess the delivery options available. There are several things you need to take note of. The fundamental ones are the coverage, shipping charges, and turnaround. Go for free shipping and fast delivery, if possible, expedited delivery. You don’t want to wait for ages to sleep on your new mattress.

Also, how the mattress is delivered matters: experts recommend mattresses that arrive in the bed-in-a-box method as they are less bulky, so you won’t have to struggle with them in the corridors or up the stairs. In this segment, we analyze the shipping and delivery of mattresses from Kingsdown and Sealy.

How Does Sealy Ship and Deliver Their Mattresses?
Sealy Deliver
The mattresses are shipped in a compact mattress in a box design. Delivery is in the larger contiguous United States though there are some exceptions.

There are no shipping charges. Sealy offers excellent service when it comes to shipping, but then, the delivery takes 5 -7 days.

Sealy can make arrangements for your old mattress disposal.

How Does Kingsdown Ship and Deliver Their Mattresses?
Kingsdown Deliver
Just like Sealy, Kingsdown mattresses can be delivered in the contiguous United States. But then, there is no white-glove service, so Sealy is undoubtedly the winner. The bad thing about Kingsdown is that the retailers set the rules regarding shipment. Some retailers may offer free shipping while others charge for the service.

Also, the delivery turnaround varies depending on the retailer. This is the same for old mattress removal. On Amazon, however, you are guaranteed fast and affordable delivery.

Do Kingsdown and Sealy Have Warranties, Free Trials, and Returns?

One last consideration when buying mattresses is the aftersales service. Here, the important aspects include the warranty, free trials, and returns. The warranty protects your mattress against any manufacturer’s defects. On the other hand, free trials allow you to try the mattress, and if it’s not comfortable, you are free to return the mattress for a refund or exchange.

Here again, Kingsdown doesn’t score so well considering it doesn’t have a definite policy regarding the mattress warranty. Though the brand guarantees a ten-year warranty, it’s the retailer who will dictate the terms. Another shortcoming of this mattress brand is the lack of sleep trials. Today, all the top brands offer up to 100 days of sleep trial. Such brands exude more confidence.

What’s the Best Choice? Kingsdown or Sealy?

Now that we have reached the end of this Kingsdown vs. Sealy mattress comparison review, the big question is, which is the best mattress brand between the two?

Well, as you have seen, there are areas in which each of the two brands excels. Below is a summary of what each mattress is best for.

Why Buy Kingsdown?
Kingsdown is a great deal for buyers looking for a mattress from a renowned brand. All the three Kingsdown mattresses in this review are innersprings. That said, they are ideal for buyers looking for excellent support. If you are a heavy sleeper, a back sleeper, a stomach sleeper, or you have back pains, Kingsdown mattresses should be on top of your wish list. They also offer a fair share of comfort and are durable.

Why Buy Sealy?
Sealy is also a renowned brand that provides consumers with quality and affordable mattresses. One thing that Sealy mattresses capitalize on is comfort. The two Sealy mattresses in this review guarantee conformity and pressure relief. On the other hand, the two hybrid models strike a balance between support and comfort.


That’s the end of this Kingsdown vs. Sealy comparison review. As you have seen, both mattresses have advantages and disadvantages. So, what do our experts recommend?

Well, if you are going for support, get a Kingsdown mattress. But if you want a mix of the two, Sealy will come in handy. In the long run, Sealy hybrid mattresses offer excellent comfort and support.

What’s more? They sleep cooler than Kingsdown mattresses. All said and done, what’s most important is finding a mattress that will allow you to enjoy your sleep. Remember, what works for you might not necessarily work for another person.
