How Are These Mattresses Built?

There are several common types of mattresses, including latex, foam, hybrid, and airbed models. Latex mattresses are made with natural latex, which is harvested from rubber trees. Natural latex is breathable and offers moderate contouring, making it a popular choice for those who tend to sleep hot but want pressure point relief. Foam mattresses conform more closely. These mattresses are known to isolate motion and relieve pressure. A hybrid mattress has an innerspring support core with comfort layers of foam or latex. Airbeds are constructed with adjustable air chambers, allowing you to change the firmness of the mattress.

The original Leesa mattress and the original Casper mattress are both foam mattresses.

The materials used in a mattress directly affect the quality of the mattress. They also determine how much support the mattress provides. Natural materials like latex tend to be long-lasting. When it comes to synthetic materials, high-density foam is more durable than low-density foam. The average mattress lasts 6 to 8 years. This lifespan is determined by materials, workmanship, and usage.

Both the Leesa mattress and the Casper mattress are constructed with high-quality materials. Each mattress uses a mix of polyfoam and memory foam, but they differ in height and construction.

Leesa

The Leesa mattress has a height of 10 inches, which is standard for a memory foam mattress. The polyfoam base is topped with comfort layers of memory foam and polyfoam. As a result, the mattress relieves pressure points and conforms closely to the shape of your body.

The twill fabric cover of the Leesa mattress is made with a polyester and Lycra blend. It is breathable with a bit of stretch to it. The cover has a 4 stripe design that is unique to Leesa mattresses. The mattress cover should not be removed, but it can be spot cleaned as needed. This is typical of most mattresses and we recommend investing in a mattress protector if you are worried about spills or stains.

The top layer of the Leesa mattress is 2 inches of high-density polyfoam. This foam has more bounce than traditional memory foam, which makes it easy to move around on the mattress. This is helpful for combination sleepers who change their sleeping position throughout the night. It is also beneficial for couples. This layer is also more breathable than memory foam. It contours to the shape of your body without restricting movement or airflow. High-density polyfoam is less likely to sag or form deep impressions over time.

Beneath the top layer of polyfoam is 2 inches of low-density memory foam. The lower density of this foam means there is better airflow throughout this layer. This prevents heat retention and helps the Leesa mattress maintain a temperature neutral feel. Memory foam relieves pressure points, especially at the shoulders and hips. Both comfort layers hug the body and result in the feeling of sleeping “in” the mattress, which is what we expect from a mattress with memory foam in the comfort system.

The foundation of the Leesa mattress is 6 inches of high-density polyfoam. This supportive layer reinforces the comfort layers and adds durability to the mattress. Having a high-density polyfoam base also ensures consistent support throughout the mattress. This helps keep the spine aligned and prevents aches and pains.

The Leesa mattress is made with CertiPUR-US certified foams, so it is low in Volatile Organic Compounds (VOCs). It is also made without heavy metals and ozone depleters. There is some off-gassing to be expected when the mattress is unboxed, since it is a foam mattress that is compressed and vacuum-sealed. However, this smell typically dissipates within a few days in a well-ventilated room. The mattress is manufactured in the United States.

Casper

The Casper mattress is slightly taller than the average foam mattress, with a height of 12 inches. The all-foam mattress has 4 layers, which include both polyfoam and memory foam. The Casper mattress offers ample pressure relief and full-body contouring.

The cover of the Casper mattress is made with polyester. The border and bottom of the cover include spandex for stretch and breathability. Like the Leesa mattress cover, the Casper cover should only be spot cleaned as needed.

The first comfort layer of the Casper mattress is 1.5 inches of open-cell polyfoam. This layer is responsive with some bounce. This offers a balance of conforming pressure relief with ease of movement. The open cell structure of the foam increases the amount of airflow throughout the top of the mattress and prevents heat retention.

Beneath the open-cell polyfoam is a 1.5-inch layer of high-density memory foam. This foam conforms to the shape of your body and relieves pressure on the shoulders, back, and hips. This layer also absorbs movement and prevents it from transferring across the mattress, resulting in fewer sleep disturbances for those who share the bed. High-density foam is more durable than low-density foam, which helps prevent sagging over time. However, it is more likely to retain heat.

The transition layer of the Casper mattress is 1.5 inches of zoned polyfoam. This layer keeps you from sinking into the support core of the mattress. It also provides targeted support. The transition foam is softer under the shoulders and legs for a cradling effect. It is firmer underneath the lower back and hips. This helps keep the spine aligned, which can reduce back pain.

The support base of the Casper mattress is 7.5 inches of polyfoam, which is thicker than the Leesa mattress. The thick foundation reinforces the mattress from edge to edge and prevents sagging over time. This makes it a better choice for sleepers who weigh more than 200 pounds.

The foams used in the Casper mattress are CertiPUR-US certified, meaning they are low in VOCs and made without ozone-depleting chemicals. Like the Leesa mattress, there is still some off-gassing to be expected when the mattress is unboxed. Any odor should dissipate within a few days and is generally not considered to be harmful.

How Do The Leesa and Casper Mattresses Feel?

Since both the Leesa and Casper mattresses are made with layers of polyfoam and memory foam, there are similarities in terms of how they feel and how they respond when you lie down. There are differences in the construction, though, that determine key factors like the amount of contouring, support, and bounce found in each mattress.

Both mattresses conform to the shape of your body, prevent pressure points from forming, and reduce aches and pains. The Leesa mattress has a closely conforming, body-hugging feel that is commonly associated with memory foam mattresses. The Casper mattress has zoned support that targets areas like the shoulders and hips.

We’ll take a closer look at the firmness, bounce, support, and temperature neutrality of the Casper vs. Leesa mattresses here. It should be noted that how the mattresses feel will be affected by your body weight, sleeping position, and personal preferences. However, this section will give you an idea of what to expect from each mattress.

Firmness

When we talk about mattress firmness, it is on a scale of 1 to 10, or extremely soft to extremely firm. The majority of mattresses fall in the middle of this scale, and are considered to be medium to medium firm. You’ll rarely find a mattress at either extreme. Side sleepers and those who weigh less than 130 pounds typically prefer a soft to medium soft mattress, or 2 to 4 on the firmness scale. Those who weigh more than 130 pounds often choose a mattress that is medium (5) to medium firm (6).

Both the Leesa and Casper mattresses are considered to be a 5 on the firmness scale. The medium firmness of each mattress balances contouring with full-body support. This firmness appeals to a wide range of body types and sleeping positions, especially side and back sleepers. In general, stomach sleepers opt for a firmer mattress.

The Leesa mattress provides the closely conforming feel that is expected from a foam mattress. The comfort system relieves pressure points and cushions the body. This is ideal for side sleepers of all weights, and back sleepers who weigh less than 130 pounds.

The Casper mattress also cushions the body and relieves pressure on the shoulders and hips. The polyfoam top layer and zoned transition layer prevent sinking in too deeply. The thicker profile and foam construction of the Casper mattress make it a great option for back and side sleepers of all body types.

Bounce

Both the Leesa mattress and the Casper mattress have more bounce than the average foam mattress, but they won’t compare to the bounciness of a latex or hybrid mattress. Latex is more resilient than foam and bounces back to its original shape faster. Innerspring coils add ample bounce to a mattress, making hybrid mattresses easy to move around on. Memory foam, on the other hand, is slow to return to its original shape and has minimal bounce.

Since the Leesa and Casper mattresses use polyfoam in the top layer instead of memory foam, these mattresses are more resilient than you might expect. However, the second layer of memory foam absorbs movement and bounces back slowly. While this adds traction to the mattress, it can make it harder to switch positions.

Bounce in a mattress is an important factor when it comes to changing positions. Generally speaking, the easier it is to move around on a mattress, the better the mattress is for sex. Without bounce, movement is restricted. The Casper and Leesa mattresses will likely be resilient enough for most couples. However, those who prefer more bounce may want to consider the hybrid versions of either model.

Edge Support and Ease of Movement

In addition to bounce, couples should also consider edge support and ease of movement. Edge support in a mattress measures how well the perimeter holds up under pressure, especially when you sit or sleep near the edge of the bed. The more support a bed has around the perimeter, the easier it is to get in and out of bed. It increases the usable surface area of the bed and prevents sagging over time.

Foam mattresses are often lacking when it comes to edge support, especially when compared to hybrid models. The Leesa and Casper mattresses are similarly rated in this category. The Leesa mattress sinks in along the edges, especially when sitting on the edge of the bed. This is most noticeable to those who weigh more than 200 pounds.

The thicker support core and profile of the Casper mattress give it a slight advantage, though the foam layers still compress under pressure. Again, this is most noticeable for people who weigh more than 200 pounds when sitting on the edge of the bed. Those who weigh less should still feel supported when sleeping near the edge.

Ease of movement indicates how well the mattress facilitates changing positions. Not only does ease of movement make a mattress better for sex, but it also makes it better for combination sleepers who shift positions throughout the night.

When comparing the Casper vs. Leesa mattresses, we found both mattresses facilitate movement relatively well. While the foam layers of the Leesa mattress are not as resilient as latex would be, they provide some traction. This prevents the feeling of being trapped or restricted by the mattress.

Like the Leesa mattress, the Casper has more bounce than other foam models. It is easier to move around on, but it still conforms to the shape of your body. This means it may not be resilient enough for some couples.

Cooling

The Casper and Leesa mattresses are similarly rated for temperature neutrality. Both mattresses take measures to prevent the heat retention and restricted airflow commonly associated with foam mattresses.

The Leesa mattress has a breathable cover and top layer of polyfoam. Most importantly, the memory foam used in the comfort system is low-density. This means it retains less heat than traditional memory foam, which prevents the feeling of sleeping hot.

The Casper mattress also has a breathable cover. The open-cell polyfoam in the top layer improves airflow around your body. However, the memory foam used in the Casper mattress is high-density. This layer is more likely to retain heat.

We wouldn’t say either mattress is noticeably cooling, but both provide a relatively temperature neutral feel. If you tend to sleep hot, the Leesa mattress may be a better choice due to the lower-density memory foam in the comfort system.

Our Recommendations

When deciding between these two foam mattresses, the choice is ultimately up to you. There are plenty of variables to consider, including personal preferences that we may not have accounted for in this comparison. Both mattresses are great choices, though one may be better than the other depending on your own needs and priorities. Based on our extensive testing and methodology, these are our recommendations.

Both mattresses offer comfort and support for every sleeping position. We found that side sleepers benefited from the close contouring of foam layers in both the Leesa and Casper mattresses. These mattresses cushion the shoulders and hips and keep the spine aligned. For back sleepers, the Leesa mattress ensures the spine is kept in alignment and the lower back is supported. The Casper mattress has zoned support that proportionately responds to the shoulders, back, and hips. Stomach sleepers may find they prefer a firmer mattress. However, both the Leesa and Casper mattress take measures to prevent the hips from sinking in too deeply while cushioning the chest.

Since the Leesa mattress and the Casper mattress have more bounce than most foam mattresses, they are easy to move around on. These mattresses use memory foam in the comfort system, which isolates motion and prevents sleep disturbances. The foam construction of each mattress ensures they are both silent when bearing weight. These factors make either mattress a good choice for couples.

If you tend to sleep hot, the Leesa mattress has an edge over the Casper mattress. It uses low-density memory foam and breathable polyfoam to increase airflow and dissipate heat. Though both mattresses are competitively priced, the Leesa mattress is a more affordable choice.

On the other hand, the Casper mattress offers better pressure relief. The thicker foam layers and targeted zones ensure that there is less pressure put on the hips, shoulders, and lower back. This makes it ideal for anyone who has chronic back pain or sharp pressure points.

Key Differences

The Leesa mattress and the Casper mattress are comparable in many ways. However, there are key differences that set them apart. One of these differences may end up being the deciding factor in your mattress search.

The Casper mattress is taller than the Leesa mattress, with a thicker support base and added transition layer. The 12-inch profile of the Casper mattress makes it more ideal for sleepers who weigh over 200 pounds, as they are less likely to sink into the support base of the mattress. The 10-inch profile of the Leesa mattress is standard, and it provides ample support and comfort for those who weigh less than 200 pounds.

The zoned transition layer adds targeted support to the Casper mattress and helps keep the spine aligned. This layer of the Casper mattress also provides better pressure relief. Softer foams cradle the shoulders and legs, while firmer foam keeps the hips from pressing into the mattress. While the Leesa mattress relieves pressure points with conforming foam, the Casper mattress has a slight edge.

The Leesa mattress is better at regulating temperature. While both mattresses are designed to dissipate heat and prevent the feeling of sleeping hot, there are key differences when it comes to construction.

The differences in construction also result in a difference in price. The Leesa mattress is frequently available for less than $1,000. This price point will appeal to budget shoppers, as it is more affordable than the Casper mattress. Keep in mind that both companies offer seasonal promotions that discount the price of the mattress.
