Casper vs Leesa: How Do Their Mattresses Compare?

What does this review include
Below you’ll find a detailed comparison guide for Casper and Leesa mattresses, including their sizing, construction, customer ratings, and performance in key areas. Both brands offer multiple mattress models but we’re going to specifically draw attention to their flagship foam models for an in-depth comparison.

The Casper Mattress and Leesa Mattress are two of the best mattress-in-a-box brands around. Casper was founded in 2013, and officially launched in April 2014. Leesa was also launched in 2015.

Both these brands have created their own legacies in the market, even beyond their superior quality mattresses. Casper is constantly ahead of the game when it comes to innovating and improving their products. Then Leesa is a Certified B Corporation, which means they are committed to social impact.

As you’re shopping for a new mattress, you’ll definitely come across these brands. At first, the mattresses seem to be very similar because they are made out of similar materials. But they are made to achieve different feelings and benefits for sleepers.

Keeping that in mind, it’s a good idea to thoroughly research both mattresses to know more about which one is right for you. And luckily, we’ve done the work for you!

Right out of the gate, we want to give you the information you need if you’re ready to make a decision.

See how the Casper Original Mattress and The Leesa Mattress compare to other mattresses in our Best Memory Foam Mattress page.

We take a closer look at each performance rating below. These ratings are based on thorough research and reviews from mattress owners and trustworthy external sources.

The material quality and mattress construction determines the value of all other characteristics that we get into below.

Both the Casper and Leesa mattress stack up in terms of their material quality. Their mattresses are made from premium, breathable foam that are certified by the CertiPUR-US program, meaning they are made without ozone depleting chemicals and harmful metals.

While they share a somewhat similar design, they differ mostly in the comfort layers. Casper is known for their tri-zoned memory foam layer that provides the right amount of support in certain areas. As such, it’s made to be softer under the shoulders and feet but firmer around the hips, waist and lower back.

Leesa’s comfort layers provide a layer of the brand’s own breathable foam that is bouncy and responsive, helping to keep the sleeper more on top of the mattress than in it. This layer works in conjunction with the memory foam layer beneath it that balances out the responsiveness with some added pressure relief.

A mattress’ durability is impacted by the materials it’s made of and the way in which it was constructed. This helps determine how long the mattress will maintain its structural integrity and comfort before it begins to deteriorate. Given that the average mattress lifespan is 8 years, this is a significant characteristic because it could signal how much longer you can have your mattress in a good condition.

Since Casper and Leesa’s flagship models are all-foam mattresses, they both show up the same in terms of durability. These mattresses are made with dense, high-quality materials that are made to last a while. Both companies also have 10 year warranties, so they share similar lifespans of 7 – 10 years.

Temperature neutrality of a mattress refers to how well a mattress absorbs body heat rather than trapping it. This trait is particularly relevant for hot sleepers and those who live in warmer climates. A mattress’s temperature control properties all contribute to a mattress’s overall breathability. This could be influenced by the materials and layer thickness.

Foam materials are known for trapping heat compared to other materials. The Casper mattress traps less body heat compared to other memory foam mattresses because it’s constructed with Airscape technology to promote more airflow to the top of the mattress.

The Leesa mattress is made with a breathable polyfoam layer on the top that won’t trap as much heat. Based on our research, it seems that Leesa sleeps slightly cooler than Casper. However, for sleepers that really struggle with temperature at night, both these mattresses may not produce adequate temperature control.

Responsiveness in a mattress is when it can tailor rearrange support to various pressure points of your body, adjust to your movements and bounce back to its original form. The level of a mattress’s responsiveness also determines how easily you can move across a mattress. This is especially important for those who have mobility issues or change sleep positions frequently during the night.

Leesa doesn’t have the bounceback of traditional innerspring mattresses, yet it still provides adequate ease of movement that allows you to move around easily on it without sinking in.

Contarily, the Casper mattress will offer more of a contouring feeling, classic memory foam cradle. In general, both mattresses provide adequate responsiveness for memory foam mattresses. They both give a balanced, cushioned feeling. Though, we would say that the Leesa mattress is slightly more responsive than Casper.

Edge support refers to how sturdy and strong the perimeters of a mattress are. If the edges aren’t strong, you might feel like you’re rolling off the edge if you get too close. And if you like to sit at the edge of the bed as you’re getting up or want full use of the surface that you share with a partner, then this benefit will be important.

In terms of edge support, foam mattresses aren’t always as secure compared to their hybrid and innerspring counterparts. It’s important to acknowledge that neither mattress will make you feel like you’re falling off the bed. However, these mattresses may fall short with edge support if you are a heavier sleeper or sit on the perimeter to get out of bed.

When it comes to the two models we’re comparing, Casper reigns more supreme in edge support. Its zoned support system in the middle helps to keep the surface of the mattress slightly more secure on the edges.

Most new mattresses will emit a slight odor once they are removed from their packaging. This is also known as off-gassing, which derives from volatile organic compounds (VOCs); otherwise known as a “new mattress smell”.

While off-gassing odors are non-toxic, they can still be unpleasant and problematic for sleepers who are sensitive to smells or have chemical allergies. Mattresses that contain solid memory foam and polyfoam materials are most likely to off-gas.

There is not a significant difference in off-gassing between Casper and Leesa. Like most bed-in-a-box mattresses, both are associated with some initial off-gassing odor, but these mild smells will dissipate in a couple days, if not a few hours after being left in a well-ventilated room.

Pressure relief is a characteristic that most people look for in a mattress. It’s usually one of the traits most responsible for a restful night’s sleep because it affects how well a mattress contours to your body, promotes better spinal alignment and relieves tension at pressure points like the hips, lower back and shoulders.

Adequate pressure relief is important for comfort, especially for those who struggle with pain. Leesa performs better than Casper in this regard because it conforms much closer to the body. Therefore, it does a great job at aligning the spine and alleviating aches and pains.

Motion isolation is mostly relevant for people that share their mattress with a partner, child or even pet. It’s the degree to which a mattress absorbs motion across the surface. If one person is a light sleeper or has a different schedule or sleep-wake cycle, then superb motion isolation helps to reduce those interferences.

Like most all-foam mattresses, Casper and Leesa’s flagship models perform very well in their motion transfer abilities. Both absorb movement to a significant degree because of their dense, multi-layered foam construction. So good news for couples—you won’t feel your partner tossing and turning in the middle of the night with either of these mattresses!

We’re not going to dance around the fact that mattresses are used for more than just sleeping. While each person or couple may be looking for something different, generally the most important traits that establish whether a mattress is ideal for sex are: bounce, responsiveness and edge support.

Both the Casper and Leesa mattresses are decent choices if you’re looking for a mattress that is suitable for sex. Many all-foam beds won’t be as good compared to hybrid or innerspring models.

Though Casper and Leesa’s original mattresses do offer some slight bounce, they tend to be less springy at the surface and most couples find this isn’t as conducive for sex.

Casper’s conforming and pressure relief properties help contour a side sleeper’s body. The zoned layer helps maintain spinal alignment by providing a significant cushion to the shoulders and hips.

Leesa’s structure is slightly firmer than Casper’s. That being said, it’s well-suited to side sleepers in the average weight range. People who fall in this realm will have all the pressure relief they need, but heavier individuals may notice a bit of pressure on the shoulders and hips.

Casper’s firmness is on the softer side, but back sleepers under 230 lbs who want a softer, cushion feel will appreciate this mattress. The memory foam layer is zoned, therefore it prevents sinkage in the midsection. Though, heavier sleepers might sink in too deeply around the hip area.

While Leesa’s original mattress is a great option for combo sleepers, if you’re strictly a back sleeper and weigh around the 230 lb range or less, then this provides great support for your lumbar region. The support layer lifts your body while the top memory foam layers will conform to the curves of your spine. Though sleepers over 230 lbs or closer to 300 lbs may appreciate the hybrid version for its pocketed support coil foundation.

When it comes to stomach sleeping, you’re usually putting a lot more pressure on the midsection. And if this is sinking too far into the mattress, you’re at risk of pushing your spine out of alignment. Casper’s zoned layer will provide support around the midsection but it might not be enough for heavier sleepers.

The Leesa is an okay option for stomach sleepers, but it’s not the best choice. If you strictly sleep on your stomach, you might be better off with a firmer mattress. While the Leesa is slightly firmer than the Casper, it has too much give around the midsection, which in turn puts uncomfortable pressure on the spine. Combination and lightweight sleepers who like to sleep on their stomach will be fine.

The Casper mattress has a medium, close body conforming feel with a fair amount of bounce. The benefit of a top polyfoam layer is its softness and responsiveness. Because of its Zoned Support System, it feels relieving for sleepers who experience frequent aches and pains. It will feel extra supportive under your core and hips and softer at your neck, shoulders and legs. If you like the feeling of a classic memory foam feeling, the Casper is right up your alley.

The Leesa mattress has a more balanced foam feeling. It doesn’t differ significantly when it comes to firmness, but it’s slightly more responsive than the Casper mattress. When you lie down on it, you’ll sink a bit, but not so much that you’re stuck. The foam layers of Leesa will provide the optimum balance of cushioning and support. If you like a balanced, easy to move surface, the Leesa is right up your alley.

All-in-all, both mattresses feel nice to sleep on. It’s now up to whether you want something that feels light and airy (Leesa) or soft and cozy (Casper).

Standout features:

Standout features:

The Leesa and Casper mattress share a lot of the same quality and traits, and are only slightly unique in their feeling, materials and construction. So it’s hard to say which mattress has the best overall value. Truthfully, we believe they are both mattresses that provide excellent value and benefits.

Ultimately deciding which mattress has the best overall value depends more on your preferences. Though we can confidently say, these are two of the best mattresses on the market as they have both generated positive reviews from customers.

What we like about Casper

We really like the Casper Original mattress for its price, superior balanced form and comfortable feeling. Sleepers who want to feel supported and hugged by their mattress will enjoy this model. In comparison to Leesa, it provides more of a slow-moving memory foam feeling. So if you’re trying to prevent or avoid back and shoulder pain, Casper does an excellent job at providing pressure relief. It also breathes exceptionally well compared to other foam mattresses.

What we like about Leesa

Then with the Leesa Mattress, we like how it’s also a relatively budget friendly option. The Leesa Original Queen mattress happens to be slightly cheaper than the Casper Original Queen. It’s also an ideal option for combination sleepers because it’s easy to switch positions. Furthermore, it’s a suitable choice for most sleepers regardless of your bodyweight. Leesa’s original mattress is more responsive than slow-moving, and offers a balance of comfort, support and stability.

We would recommend the Casper and Leesa flagship mattresses to just about anybody looking for a supportive and comfortable sleep surface. But it’s up to you to determine how well either mattress would meet your specific needs.

There is likely something that stands out to you in one more than the other and we advise you to trust your gut on this one. If all else fails—they both have 100 day return policies!
