Casper vs. Leesa Mattress

Casper or Leesa? Which one is better? While Casper offers great support and comfort for individuals with less than 230 pounds who in different sleep positions, Leesa is suitable for any weight group, all sleep positions and those who sleep hot on foam beds.

The brand Casper started in 2014 with its flagship model named Casper. It was designed as a Medium firm, with a triple-layer comfort system that is combining polyfoam and memory foam, and a high-density foam support core. Leesa also launched in 2014. Its flagship, a Medium firm as well, has comfort layers made of polyfoam and memory foam and a base layer made of high-density polyfoam.

Today, both brands sell many other beds. Among others, Casper offers the Casper Wave – with a mix of memory foam and latex, and the Casper Essential – made of memory foam. Leesa also has the Sapira – a hybrid memory foam mattress. The brand models have many similarities such as the firmness setting, construction, history, and pricing. But each of them has unique attributes that give the bed both advantages and disadvantages when compared to other brands.

In this article, we will compare Casper and Leesa mattresses.

Quick summary

Casper mattress offers great support and comfort for individuals with less than 230 pounds who sleep on their backs, stomachs, or side, sleepers with chronic back, neck and shoulder pain, and couples.

Leesa mattress offers great support and comfort for individuals in any weight group who sleep on their backs, stomachs, or side, those who sleep hot on foam beds, and people who need a moderate amount of conforming.

Mattress Specs

Casper Mattress

Casper is a Medium Firm foam mattress with a 5.5 firmness setting. The model is excellent for back pain. It is sold at an affordable price of $1,195 for a Queen size. Along with it comes a 120-month warranty with 100-day sleep trial and free shipping, and it weighs 71 lbs. The Casper has three comfort layers. The top and bottom layers are made of polyfoam, while the middle layer is made of memory foam.

The bed’s cover is made from a thick, soft polyester blend that won’t bunch up during the night because it can snap back quickly. Also, it can be removed with a zipper for cleaning. The comfort layer consists of a latex-like foam material that provides a little bounce to the bed while allowing the person to sink into the foam and get good pressure relief. A person receives a zoned feel that gives pressure and pain relief to various areas of the body. Certain body and environmental temperature can positively or negatively affects you sleep. Casper has excellent temperature neutrality, with minimal body heat absorption that allows the person to sleep reasonably cool.

A layer of memory foam that is located below the cover gives an excellent body-contouring feeling while keeping the extended pressure relief of the top layer. Underneath it is a zoned support system with two types of polyfoam – durable and soft. The base is made from heavy-duty polyfoam that is responsible for the bed’s structure. The durability of the mattress is fair. Many owners have stated that the models have a decent performance, but it is still to be determined since the company has been in business only a couple of years. These foams are much firmer under the person’s core and hips, but softer under the head, shoulders, neck, and legs.

The bed’s motion is excellent, and it minimizes movement to a great extent, which makes it suitable for couples. It isn’t too responsive or even bouncy, so it doesn’t rank high in terms of sex. But the construction of the model offers excellent conforming, with targeted pressure relief, just like other mixed foam mattresses. The edge support is minimal, so sinkage around the edges is possible. It is silent when weight is applied, but some owners have moderate off-gassing after purchase.

Other company’s signature models are Casper Essential and Casper Wave.

Leesa Mattress

This Medium Firm foam mattress has a slightly less firmness setting – 5 on the firmness scale. Just like The Casper, the model is excellent for back pain. It is sold at an affordable price of $845 for a Queen size. Along with it comes a 120-month warranty with 100-day sleep trial and free shipping. And it weighs 71 lbs.

The cover is made of a thick polyester blend that gives a cozy and soft feeling. The comfort system has two layers. The upper one is made from 3 PCF polyfoam with an indentation load deflection (ILD) of 13 that is responsible for the moderate firmness, and the lower contains 3 PCF memory foam with an ILD of 9 that gives the bed a soft feel.

The comfort layers offer a bouncy and responsive feeling. Below is a memory foam layer that has a slow response to pressure which is excellent for body contouring. The last layer is made of high-density polyfoam that gives the bed its shape, support, and stability. The support core consists of high-density 1.8 PCF polyfoam that has an ILD of 32. The core gives the bed a firm feel, but the base layer of six inches is what reinforces the structure of the model and stops sagging.

The durability is good, with around seven years of use. The motion isolation is very good because of the multi-layered foam construction that reduces motion transfer, and this is what makes it great for couples. When speaking about couples, even though the mattress has some bounce, it is not responsive enough for sex.

Although some owners complained it sleeps hot, the bed is relatively cool, especially when you compare it to other foam-based models. The edge support is fair, just like its competitors – not better, not worse. But they are silent when weight is applied. It also conforms closely to the body and helps alleviate pains and aches, and aligns the spine. However, larger sleepers complain that it lacks support for them. Many also complained about the off-gassing odor, but it disappears in a few days.

Apart from trying out Leesa memory foam model, we also recommend the Leesa hybrid mattress with additional sleep enhancing features, as well as Leesa hybrid pillow.

Sizes and Pricing

Both the Casper and Leesa are available in six sizes. The prices for twin sizes are $695 for Casper and $525 for Leesa, while the twin XL are $745 and $695. Looking at the twin bed prices, Leesa is much cheaper, with the twin XL being the same price as Casper’s regular twin.  The same goes for other sizes, as well. The Leesa is much cheaper than the Casper. The Full-size bed costs $1,095 for Casper and $855 for Leesa. The prices for the Queen are $1,195 and $995. The price of a King size is $1,495 and $1,195, while California King $1,495 and $1,195.

Mattress Construction

Each model has a different material composition, firmness, and thickness. The firmness level for Casper is Medium 5.5 and for Leesa Medium 5., while the thickness is 9 1/2″ for Casper and 10″ for Leesa. The weight for both beds is 71 lbs. The Casper’s comfort layer consists of one layer of 1/2″ 4 PCF memory foam, one layer of 1/2″ polyfoam, one layer of 1/2″ 2 PCF polyfoam, while Leesa’s model has layers of 2″ 3 PCF polyfoam and 2″ 3 PCF memory foam. The Leesa’s support core is made of  6″ 1.8 PCF HD polyfoam, while the Casper has 5″ 1.8 PCF HD polyfoam. Both beds have covers made from polyester, but Leesa also includes Lycra® Spandex with the polyester blend.

Sleep Position Ratings

The Caspers has many foam layers that provide close conforming. These layers also help align the sleeper’s spine while alleviating pressure points for individuals in all weight groups. However, since it is a Medium Firm, it is most comfortable for those who weigh less than 230 pounds and sleep in any position, even combination sleeping.

The Leesa has exceptional balance support and cushioning with its construction that is made of mixed-foam. It is comfortable for people of all weight groups to sleep, regardless of the sleep position. It also sleeps very cool, making it an excellent choice for those who sleep hot on foam models.

Individuals in the lightweight group – those with less than 130 pounds, will sleep very good on their side or back, and sufficient on their stomachs on Casper, and good in any position on Leesa. Side and back sleepers in the average weight group – between 130 and 230 pounds will sleep very good on Casper, while back and stomach sleepers will sleep very good on Leesa. Side sleepers in the heavyweight group will sleep good on both brands, while back sleepers will sleep good on Casper and very good on Leesa. However, stomach sleepers with more than 230 pounds need to choose carefully – Casper will offer fair sleep, while Leesa can provide good sleep.

Delivery, Warranty, and Sleep Trials

After comparing their construction, let’s talk about the most important aspects of shopping – delivery, warranty and sleep trials.

Casper has a non-prorated warranty that lasts 120 months, with a 100-day sleep trial. However, the sleep trial doesn’t cover a mandatory break-in period, but you can return the bed anytime during this period and get a full refund if it was ordered from Casper. Purchases placed on and other retailers may include additional fees.

Exchanges are available only during the sleep trial period, and exchange for a different color will void the remaining sleep trial, while a separate model will get a new 100-day sleep trial. The warranty is entirely non-prorated – with all shipping charges covered by Casper. It covers 1″ or more in-depth sagging or indentations of the sleep surface, along with physical flaws that lead to splits or cracks and cover zipper defects.

Customers receive the product within two to seven business days after placing the order. The Standard UPS delivery is free of charge, but White Glove delivery with the in-home assembly will cost $149. The product is compressed and shipped in a box, and it can be delivered anywhere in the U.S. and Canada.

Leesa also has a non-prorated warranty that lasts 120 months, with a 100-day sleep trial as well. However, Leesa’s sleep trial does consist of a mandatory 30-day break-in period, which means customers won’t be able to get a full refund until they test it out for 30 days. And the sleep trial will be voided if the bed is transferred outside of its original country of purchase. But Leesa does have prepaid shipping labels with which you can return the product free of charge.

The 120-month warranty is entirely non-prorated, but it is voided if the product is not used with a supportive base or foundation. The company will cover the costs of having the mattress repaired or replaced, but associated shipping charges will fall on the owner. The warranty covers 1″ or more in-depth sagging or indentations of the sleep surface, along with physical flaws that lead to the foam being damaged when in proper care and use, cover defects and issues with seams or zippers.

Customers receive the product within three to seven business days after placing the order. The standard delivery is free of charge, and White Glove delivery is available for select locations with the in-home assembly will cost $100. Removing the old model will cost $50 more, making the total $150. The product is compressed and shipped in a box, and it can be delivered anywhere in the U.S., Canada, the U.K., and Germany. But White Glove delivery is not available in all locations. Any changes to the customer’s shipping addresses need to be made within 24 hours of placing the order.


Both mattresses have their benefits and downsides, so you need to consider all of them very carefully and find an adequate model for you. To help you choose, we are going to show you some of our recommendations for both beds.

You should choose Casper if you have chronic pain in your lower back, shoulders, or neck. It is suitable for any sleeping position – stomach, back, side or combination, but it is most comfortable for individuals with 230 pounds or less or those who sleep with another person. It may not be suitable for people who sleep hot or want a different firmness setting – softer or firmer than the Medium Firm.

People who want a bed that conforms to a moderate extent should consider getting Leesa. It is also suitable for those who sleep hot or can be easily woken up by their partner’s movements in bed or even noise. But it is not ideal if you like your mattress to conform closely or you need a model that is firmer or softer than a ‘Medium’ feel.
