There’s a lot to consider before you finally settle on the best mattress for you, and it can be a job to navigate through all the options. So, we’ve done some of the hard work for you and put together a comprehensive comparison of two popular mattresses—Leesa vs. Casper.

We’ll cover everything from the firmness level to the materials, to the pros and cons of each mattress and even give you our detailed conclusion so that you can make the best-informed decision between the Leesa vs. Casper mattress.

Construction: Leesa vs Casper

You always want to consider just what your mattress is made of. Different materials offer different qualities. While that doesn’t necessarily lessen the value of individual materials, it does make a difference when finding a mattress that will meet your needs.

Casper Construction

The Casper Mattress is constructed with several layers of memory foam and latex foam to provide the best qualities of both materials. The top surface of the mattress features 4 layers of foam to relieve pressure off of joints and pressure point areas. The memory foam construction is specifically designed to mold to the body and gently cradle problem areas to avoid pain and stiffness night after night.

The top layer is constructed with zoned support to ensure that you’re getting the right amount of firmness vs. softness in all the right places. This helps to achieve optimal neck and spine alignments and guarantees a more comfortable sleep.

Underneath the memory foam layers of the Casper mattress, is a supportive layer of latex foam. This layer provides reinforcement throughout the entire mattress to ensure that you’re supported from one end to the other. The latex foam also allows for optimal temperature regulation and just the right amount of bounce.

Leesa Construction

The Leesa mattress is constructed with 3 individual layers to provide you with the ideal overall mattress. The very top layer of the Leesa features a 2” layer of Avena foam. This layer has been perforated to allow for airflow and breathability and assists in keeping you cool throughout the night. This layer also serves as the first line of comfort, providing you with a supportive, huggable comfort.

Underneath the layer of cool Avena foam, the Leesa is equipped with a 2” layer of memory foam that provides you with the best qualities memory foam has to offer. This layer is specifically designed to mold to your body and allow for the perfect level of support and pressure relief and cradle the joints to reduce pain and stiffness.

leesa vs casper

Bringing up the bottom of the Leesa mattress is a 6” layer of core support foam. This layer reinforces the top layers of the mattress and ensures a supportive, stable, and long-lasting mattress.

Who Wins?

When considering the Leesa vs Casper, they’re both constructed with high-quality materials and built to be comfortable, supportive, and long-lasting. Both mattresses feature at least a few layers of memory foam, combined with other materials to make for a great overall mattress.

However, the Casper does utilize Latex foam, which is known for its lifespan and durability, as their base layer to reinforce the mattress. Because of latex’s known durability, it does lend the edge to Casper for construction.

Temperature Control: Leesa vs Casper

One of the biggest deciding factors when purchasing a mattress is how well it will control your temperature while you sleep. A hot mattress will make for a miserable night’s sleep, leading to tossing and turning, frequent waking, and groggy mornings due to a restless, hot night.

So, how well does Casper vs Leesa stack up when it comes to temperature control?

Casper Temperature Control

The Casper mattress guarantees a cool sleep in a few different ways. The top layer of the mattress features an open cell foam that utilizes the powers of convection and conduction to actually move heat away from your body. The memory foam layer provides the ideal level of airflow and breathability to extract any heat from the top of the mattress, where your skin is exposed and move it down and away while you sleep.

The bottom layer of the mattress is made with premium latex foam. This layer is specifically designed as a second line of defense against heat retention, absorbing heat from the top of the mattress and distributing it evenly. The latex layer combined with the open cell foam and breathable memory foam layer work together to not only simply pull heat away from your body as you sleep but actually allow you to sleep cooler.

Leesa Temperature Control

The Leesa mattress’s main line of defense against heat retention is the top layer of perforated Avena foam. The punctures in the foam layer allow for optimal airflow through the mattress and overall breathability to help keep you cooler through the night.

They also use high-quality but light foam to help ensure that there are no dense materials that will absorb and trap heat against the body.

Who Wins?

While both the Casper and the Leesa mattress boast some sort of temperature regulation, the Leesa only has one true line of defense in their top perforated layer. Whereas, the Casper mattress utilizes every single layer of the mattress to help pull heat away from the body, disperse it evenly, allow for optimal airflow, and actually make you cooler through the night.

So, in Casper vs Leesa temperature control, Casper certainly takes the win.

Firmness: Leesa vs Casper

Firmness can be a tricky thing to get right when searching for a mattress, simply because everyone is different. Some people prefer to sleep on an extremely firm surface, while others are looking for a softer, plusher mattress. There really is no “right” level of firmness, rather just a firmness that is right for you.

However, if you’re unsure on how firm you want your mattress to be, then it’s best to look for something that provides a happy medium—a just right level of firmness combined with soft comfort.

Who hits the spot-on firmness in Leesa vs Casper?

Casper Firmness

The Casper mattress is primarily made with memory foam, which is not usually known for being super-firm. However, it is backed up by a significant layer of latex foam, that helps to provide that level of firmness and support that a lot of sleepers are looking for.

This mattress is described as medium-firm. So, if you’re looking for super-firm or super-soft, it doesn’t really reach an extreme on either end of the spectrum. But, it does seem to provide a happy medium. The latex layer allows for a base platform of support, while the memory foam top layers provide a nice level of plush comfort and a cradling effect.

Leesa Firmness

The Leesa is also considered a medium-firm option. It rates a 6 on the firmness scale, with 10 being the firmest available, and 1 being super-soft.

Again, it’s primarily constructed with memory foam, in addition to other foam materials, so it’s not known for being a super firm option. Rather, the Leesa falls somewhere in the middle. This mattress allows for a firm, supportive base, with a soft, plush top layer that will provide comfort and a cradling effect where you need it most.

Who Wins?

Both options are considered medium-firm, meaning they’re not super-firm, nor super-soft. Both the Leesa and the Casper boast the perfect blend of soft comfort and firm support, and both boast the ability to relieve pressure, pain, and stiffness. However, based on reviews, Casper beat out Leesa on that “just right” level of firmness.

Price: Leesa vs Casper

Oftentimes, the biggest deciding factor when making any large purchase comes down to how hard it’s going to hit your wallet. You want to ensure that your purchase is worth your money, and it never hurt anyone to be a bit thrifty and compare prices.

When considering the Casper vs Leesa, which will be the easiest on your pocketbook?


The Casper mattress comes in at $805.50 for a full-size mattress, $895.50 for a queen size, and $1075.50 for a king. As far as mattress prices go, the Casper is pretty much right there in the middle. Of course, there are mattresses on the market that cost far more as well as options that are far cheaper. However, when purchasing a new mattress, the phrase, “you get what you pay for” certainly rings true. For the amenities that you’re receiving from the Casper mattress, the price is pretty neutral.


The Leesa mattress will cost you $730 for a full-size mattress, $845 for a queen, and $1070 for a king size. Again, these prices are pretty neutral for a new mattress that offers great qualities and amenities such as temperature control, quality construction, and joint pain relief.

Who Wins?

When it comes down to the Leesa vs Casper, Leesa takes the trophy in price. While it’s not a huge difference, only a bit over $5 for the king size Casper vs. Leesa, the Leesa still comes in as the cheaper option.

Pros & Cons of the Casper vs. Leesa

One of the best ways to determine whether you’re making a good purchase is to take the advice of those who’ve already bought it. Reviews can be a huge deciding factor when making a large purchase decision, such as deciding between the Leesa vs Casper, because you can get the first-hand experience, without ever having to make a purchase.

What Do Reviewers Absolutely Love About The Casper?

The biggest praise given by reviews of the Casper mattress is the “just right” level of firmness Vs. comfort. Over and over again, reviews have hailed the Casper for providing them with the perfect amount of cradling softness around joints and pressure points, while still remaining firm and supportive throughout the areas that need it. Many reviews have even mentioned that they suffer from arthritis or back issues, and the Casper has greatly improved their quality of sleep and allowed them to wake every morning without pain.

Overall Pros

  • Casper offers a significant sleep trial and a decent warranty
  • Reviewers praise the just right firmness of the Casper mattress
  • Th Casper mattress comes with an affordable price tag
  • The several different layers of temperature control not only pull heat away from you but actually allows you to sleep cooler
  • Reviews compliment Casper’s friendly and timely customer service

What Are the Drawbacks of the Casper Mattress?

One of the biggest reviewer complaints on the Casper mattress was a lingering odor. The mattress is delivered rolled and vacuum packed and Casper does recommend allowing at least 72 hours in a well-ventilated area for the “fresh foam” smell to dissipate. However, some reviewers have noticed that even after the 72-hour period, the mattress still has a lingering odor.

Overall Cons

  • Some sleepers have reported that the Casper mattress wears down quickly, only providing medium-firm support for around 6 months to a year
  • Because it arrives vacuum packed, it can take several hours, up to 72, to fully expand and be ready for use
  • There is very little to no edge support in the Casper mattress, leaving you to roll off the bed, and sitting on the edge of the bed can cause strenuous wear
  • Reviewers have reported that, when sleeping with a partner, the mattress seems to sink to one side

What Do Reviewers Love About Leesa?

Most reviewers rave about Leesa’s overall comfort. No matter if you’re a side-sleeper, back-sleeper, stomach-sleeper, or if you’re one of those that hit every sleeping position throughout the night, the Leesa never fails to provide you with the best all-around comfortable experience.


  • The Leesa company provides a decent warranty and trial period, with a 100-night trial and 10-year limited warranty
  • The price of the Leesa mattress won’t break the bank
  • Reviewers boast that the mattress provides an ideal level of firmness
  • For every 10 mattresses purchased, Leesa donates one to a homeless shelter
  • The Leesa mattress is 100% made in the USA
  • The Leesa mattress is specifically designed to adapt to individual bodies, making it a great option for couples

What Are the Drawbacks of the Leesa Mattress?

The main complaint made by reviewers of the Leesa mattress is the fact that it falls a bit short in cooling properties. A lot of consumers have noticed that it just doesn’t pull away heat proficiently, and oftentimes leaves them sleeping hot and sweaty.


  • An odor is noticeable upon opening the Leesa mattress and some consumers have reported that the smell lingers up to weeks
  • Some consumers have reported that the Leesa is a bit too firm for their taste and they require an additional mattress topper to achieve optimal comfort
  • Returns can be a hassle because you have to ship it back
  • The Leesa has almost no edge support, leaving you vulnerable to rolling off and causing additional wear if you sit on the edge often

Warranties: Leesa vs Casper

A good warranty is an important factor in any large purchase decision but especially for something as significant as the mattress you’ll be sleeping on every night.

First and foremost, a good warranty equates to good quality. A company simply is not going to back up a product that they’re not completely confident in. Furthermore, you don’t want to fork out over a thousand bucks for a mattress, only to discover it’s defective and be left footing the bill for a replacement.

So, who has the best warranty in Casper vs Leesa?

Casper Warranty

One of the main goals for the founders of Casper was to give consumers the opportunity to try their mattress out for an extended period of time before making any final commitments. So, naturally, Casper offers a 100-night risk-free trial on their mattresses. If you’re not completely satisfied and entirely in love with your Casper product, they will not only refund you the purchase price but pick it back up themselves.

If you love your Casper purchase and decide to keep it after the 100-night sleep trial period, you’re still protected with a 10-year warranty. As long as you are the original purchaser of the Casper mattress and you bought it directly from Casper or one of their authorized retailers, then Casper will cover the replacement or repair of the product if it’s found defective. Covered defects include; deterioration of the mattress that leads to an indentation greater than an inch in depth, any splitting or cracking in the foam construction with normal use and handling, and any defects in the zipper assembly on the mattress cover.

The warranty does not cover any strenuous abuse or destruction of the mattress and its components, any Casper mattress bought used or from an unauthorized dealer and will only replace or repair specifically damaged hardware (meaning if the zipper breaks, they will only replace the zipper, not the entire mattress).

Leesa Warranty

Leesa offers a 100-night happiness guarantee. Meaning you get to take your new Leesa mattress home, set it up, and sleep on it for a full 100 nights to determine if you’re going to be 100% happy with your purchase. If by chance, you don’t love the Leesa mattress, then you can return it for a 100% full refund.

The Leesa company also offers a 10-year limited warranty. This warranty guarantees that the Leesa company will replace or repair (at their discretion) your Leesa mattress so long as the problem meets the terms of their warranty. The Leesa mattress is made to be supported by a solid frame. The company is not liable for any problems that are experienced with the Leesa if the mattress has not been used properly on a supportive, appropriate frame.

The 10-year limited warranty covers an indention of at least an inch or greater, any physical defect that causes irreversible damage to the memory foam, and any errors in the cover including the seams and zipper hardware. It is important to note that Leesa may choose to replace your mattress cover instead of repair it, and it will be replaced with the style of cover that Leesa is currently using. This means that the color and design could differ from your original cover.

The warranty does not cover any defects that are caused by improper use, extraordinary abuse or damage to the mattress such as cuts or burn holes, any normal increase in softness so long as it does not affect the pressure-relieving abilities of the mattress, and it does not cover any mattress bought from an unauthorized dealer or purchased used.

Who Wins?

When it comes to Casper vs Leesa, in the end, they both offer virtually the same warranty – a 100-night sleep trial and a 10-year limited warranty. The terms of their warranties are mostly the same as well, they will repair or replace, at their discretion, within 10 years so long as the mattress has been used properly and has not been subjected to abuse by the owner.

However, Casper does have a slight leg up in the fact that they will personally come and remove the mattress from your home if you’re not satisfied during the 100-night sleep trial.

About The Companies

When making any large life purchases, it’s always nice to know a little bit about who you’re buying from. What got them started? How long has the company been in business? Have they received any awards or accreditations? What makes their company worth your business?


The Casper Mattress Company was founded by five individuals who wanted to revolutionize the way we shop for and buy mattresses. Like many other consumers, they found it strange that you were expected to choose a mattress to sleep on night after night with just a few minutes inside the store. So, in 2014, they launched the Casper Company that sells online, directly to the customer, and allows for a significant trial period to allow you to acclimate to your new mattress and make a truly informed decision before making any final commitments.

Since their launch in 2014, Casper has been recognized by several entities including Good Morning America, Forbes, and The New York Times. Casper was named one of the most innovative companies in 2017 by Fast Company. In 2018, they were Good Housekeeping’s Lab Pick. Casper now boasts the label of “The internet’s favorite mattress.”


The founders of the Leesa mattress company wanted to make buying a mattress simpler and cheaper. So, they set out to cut out the middleman and all of the middleman costs and created a company where you could purchase high-quality, comfortable mattress at an affordable cost, without being left to shop through store after store and deal with all the sales pitches that come with it.

The Leesa company is determined to make a good impact on this world. As a matter of fact, the company boasts the fact that they’re concerned just as much about their footprint left in the world as they do about their profits and revenue. To achieve those goals, the Leesa company supports their local community, plants trees to reduce their environmental impact, and donates one mattress for every 10 sold to a homeless shelter.

So, What’s Conclusion?

When it comes down to it, both the Leesa and the Casper are great options when considering your new mattress purchase. Both mattresses are constructed with memory foam to provide the perfect ratio of firm support and plush comfort.

While the reviewers of the Leesa bragged about the overall comfort that it provided, and we certainly applaud Leesa’s environmental and social contribution, in our review the Casper did beat out the Leesa in several categories. So, if you’re looking for a mattress that will provide ideal firmness, support, pressure relief, and fantastic temperature control, then the Casper is most likely the best option for you.
