In online mattress trade, the two most famous beds are Leesa and Casper; they are the most popular among direct-to-consumer mattresses. You have likely come across any of these beds in your search for mattresses online.

These beds have long years of successful customer patronage with thousands of happy users. In this discussion, we are sticking with our tradition of reviewing the flagship of both products instead of their other brands like Casper's Wave or Leesa's Hybrid beds. 

Both beds have memory foam as their core material. Leesa is a three-layered in structure while Casper is four layered. These beds use memory foam and other foam variants to deliver unique value in their support, contouring, and bounce.  

Despite several benefits delivered by both beds, each one is unique in their value and appeal to different sleepers. Therefore, this review is aimed to guide sleepers to choose the mattress that most satisfy their need.

The Brands Behind The Beds


David Wolfe established Leesa in 2015 to create a mattress with improved quality and affordable price. The company aimed at eliminating bed that is costly and filled with useless fillers typical of traditional manufactures. Currently, Leesa mattress is suitable for most types of sleepers. 

Leesa is proudly US manufacturer committed to high-quality mattresses. The company is a ‘10 to 1’ philanthropist who gives on a bed to charity for selling ten mattresses. To date, Leesa has given out more than 30,000 beds to charity organizations. 


Casper is currently a household name in the online mattress today. The brand and company have received countless accolades from industry leaders. It’s a regular feature in celebrated publications including the New York Times and Forbes among others.

Since its launch in April 2014, Casper has grown as a mattress of choice across North America, including the US and Canada.

Casper unique product is 100% made in the USA using safety-certified components to deliver unique and high-quality mattresses. Within a short time of its presence, the brand has experienced tremendous growth. Its success and industry leadership are thanks to exceptional innovation and customer friendly services.

Mattress Construction Comparison

The products, Leesa vs. Casper, use 100% foam with unique quality variations identifiable to each brand’s layers and foam types.


This mattress has high-quality foam structured in three simple layers. The design of each layer delivers specific quality and purpose. The three layers combine to produce affordable cost and fantastic sleep experience.

The Leesa mattress cover is from quilted poly-lycra blend fabric; the same highly breathable and comfortable material used in sports clothing.

The top foam layer for this mattress has 2 inches of LSA200, a unique type of foam for unparalleled comfort.

The LSA200 foam offers numerous benefits, including:

  • The cooling and comfort of latex foam and more durability.
  • A softer bounce, better for sleeping than Casper.
  • Breathable, cool and moisture-free at night.
  • Excellent motion transfer inhibition for an interrupt-free night for couples.

The Leesa mattress second layer consists of 2-inches of memory foam responsible for body contouring and pressure relief. This layer gives Leesa a definite edge above its competitors at the current price.

The foundation layer, at the bottom of the Leesa, is 6 inches of high-density support foam.  The base layer and two other layers give Leesa its 10-inch thickness. The foundation foam offers base support and breathability to help further the mattress remain cool on warm summer nights.


Concerning the construction of their mattresses, Casper is quite different for Leesa. 

In the Casper mattress, there is a layer of open-cell foam, which is directly above two memory foam layers.

The open-cell foam structure at the zenith of Casper’s mattress does not only regulate temperature but also makes the layer bouncier. This amount of bounce surpasses that of the Leesa, making the caper quite better for affectionate couples.

As said earlier, the dual memory foam layers, which follow the open-cell structure, aid contouring, support, as well as pressure relief during sleep.

Following these is a third-zoned layer of foam, which included three different foam types with different densities: the firmer foam at the hips region provide extra support for the hips, while the softer foam at the shoulders zone provide contouring for the shoulders, making the updated Casper model a good pick for side sleepers. 

At the mattress’s bottom is a layer of foam with high density, which supports the entire bed as a whole. 

Like the Leesa, all the layers of the mattress sum up to 10 inches in thickness.

Although the materials used in the Casper are not entirely organic like the Leesa, the memory foams, as well as the foundational foams used in the mattress have CertiPUR certification.

Firmness Comparison

On the 1-10 scale, we rate the Casper at 6, while the Leesa, 5.5. Although both brands similarly come within the Medium to Medium-Firm range, the Leesa is slightly softer than the Casper.

Equally, Leesa and Casper’s construction was designed to suit a wide range of sleepers with different sleeping positions. Besides, they both have a similar construction pattern; the top layer begins with soft, responsive materials, which are breathable. This layer is usually followed by less-responsive materials with contouring abilities, and finally, are denser materials, which provide support to the other layers of the mattress.

With the Zoned Support™ in Casper’s mattress, Casper is excellent at maintaining spinal health. This feature, due to the extra firmness around the center, is particularly helpful for heavier sleepers, who have more weight around their abdomen. Strict stomach sleepers would love this feature more than anyone else.

Leesa has slightly better pressure relieving features than Casper, because of its possession of softer and thicker comfort layers. This feature is more appreciated by side sleepers, who need more pressure relief around their shoulders and hips, as they put more pressure on those areas, which are not wide enough for the weight they hold. Even though the Leesa will support back and stomach sleepers adequately, side sleepers should appreciate Leesa better for adding additional comfort and cushioning alongside its softness. 

Even though these models have their special sleeping positions which they work better with, they are still multi-functional enough to suit a wide range of sleeping positions, as well as body types of different sleepers.

As for Casper, there is no limit for weight, although Leesa advises a weight limit of 300 lbs. People who worry about weight limits and specifications should note that with both companies, you can get the upgraded models, Casper Wave, and the Sapira, for Casper and Leesa respectively, which includes more supportive materials.

Sleep Experience

As they are both all-foam mattresses, they Casper and Leesa offer quite similar sleep experiences. However, with detailed information, there are significant differences which allow you to decide better.

Temperature Control

Both the Casper and Leesa do good jobs at keeping heat away. Although all-foam mattresses usually have problems with sleeping hot, these two brands are not known for sleeping hot. The open-cell foam structure in Casper does not allow heat retention. Additionally, the firmness of Casper does not let the body to sink into the mattress, eliminating the possibilities of trapping heat around the body. The Leesa mattress, like the Casper, also incorporates the bouncy Premium Foam Layer, which prevents heat retention better than most traditional memory foams. 

Motion Transfer

The Leesa, even with its bouncy nature, efficiently isolates motion to a reasonable extent. Thus, many users report how wonderful it performs in this field. Conversely, although the Casper is also quite efficient in this field, it does not work as effectively as the Leesa. Overall, both brands are suitable for couples who do not want movements from the other partner to disturb them while sleeping.


Responsiveness, for a mattress, means that the foams in the mattress respond to the pressure applied to them, based on the amount of weight and tension involved. Thus, such bed will contour to and support the sleeper’s body, and therefore, promote spinal health. This feature is essential for every sleeping position, and it is a remarkable feature in both the Casper and the Leesa. Although both brands have enough responsiveness, the Casper is slightly more responsive than the Leesa.

Resilience and Bounce

When weight is put on foam mattresses, the foams compress and decompress when the pressure is withdrawn. Concerning resilience, we are looking at how fast the foams decompress back to their original forms. Thus, a mattress with more resilience will allow faster re-bounce and will be bouncy enough to allow smooth movement on the bed. The latex-resembling foam in the Leesa results in a very resilient surface. While the Casper also is resilient, it is not as resilient as the Leesa.

Edge Support

Both the Casper and Leesa score weak points at edge support, as they do not make provisions for extra reinforcements around the perimeters of the mattress. Thus, if you sit or sleep close to the edge, you might not get enough support. So, if you are keen on a bed with perfect edge support, try to consider a mattress with reinforced edges, or one which is not an all-foam model.

Off-gassing and Smell

During their first installations, both brands equally off-gas. However, these odors are not harmful, and they only last a short while, usually within a few hours or days, as long as the room has proper ventilation, i.e., enough airflow. 

Warranty and Returns

Leesa and Casper are almost equal in terms of their policies on returns and warranties; buying from either of them is very safe.


  • A 100-night trial period for customers.
  • Within the 100-night trial period, there is room for returns and a complete refund.
  • When mattresses are returned, they are given out to charities.

Casper Mattress vs. Leesa Mattress – Which One Should You Buy?

It can be quite tricky to choose between two mattress brands that share almost every feature and function. This process is particularly cumbersome for Leesa and Casper, as both companies have good qualities and accomplishments in the mattress industry, as well as excellent customer reviews and satisfaction. The following guidelines might help to enlighten you, which one will suit you better amongst these two leading brands. 

Purchase the Casper mattress if:

  • You crave for more contouring and hug: although the Casper does not offer perfect hug and contouring, it is still a better option than the Leesa in this field, and thus, is a better option for hug-loving people.
  • You sleep on your back: even though the Leesa also works quite well in this field, with its extra firmness, the Casper has the edge over it for back sleepers. It is especially perfect for back sleepers since his set of sleepers love firmer surfaces for extra support and comfort during sleep.

Purchase the Leesa mattress if:

  • You are a combination sleeper: perhaps you move around and turn on your bed while you sleep at night. If yes, then, you should crave for a mattress which will allow you to move and toss around on top of it without problems. For such a feature, you will need a bouncy mattress like the Leesa. With the bounce of the Leesa, you will enjoy moving around on your bed. And, since the mattress is very responsive, combo sleepers will receive enough support, irrespective of the position they use to sleep.
  • You enjoy more bounce: since the Leesa comes with a latex-resembling sleeping surface, it is bouncier than the Casper. The springier feature also aids sex between couples and does not make you feel like you are stuck in your bed. 
  • You prefer knowing complete specifications of a mattress: while the Casper holds back most of its specifications as proprietary, provides in-depth details about their mattresses. So, if you are keen on having this information, you should pick the Leesa over the Casper.
  • You place significance over a charitable mission: for every ten mattresses that Leesa sells, they give one out to charity. So, if you buy from Leesa, you are also giving out to charity indirectly. This act is a part of the company’s dedication to giving back. 


Equally, the Casper and Leesa are remarkable brands, which offer quality at reasonably affordable prices. So, although it can be challenging to settle on buying one since they both come with 100-night sleep trials, you can try each model out to find out the best one for you- buying either of them is not, at all, like taking a risk.

However, whether you finally settle for the Caser or the Leesa, you are sure to receive total satisfaction from your decision as a customer. Protection Status
