The Leesa and the Casper mattress are very similar, both in construction, in feel and even in price, so it can be difficult to figure out which is the best one for you. Both are made with a hybrid foam construction, meaning that they are built with several layers of different kinds of foam.
Both have sturdy base layers of high support foam, meaning that they operate similarly in terms of motion transfer.
But there are some subtle differences between the two, with the Leesa being slightly firmer with a bit less sink than the Casper mattress.
By pouring through the hundreds of reviews of each mattress, we have determined that the Leesa mattress is best for averaged sized people, under 230 pounds but is also comfortable for larger people. People who sleep on their backs, sides and stomachs are all generally satisfied with this mattress.
People who sleep on the Casper mattress who are average sized are also generally satisfied, sleeping in all positions. But heavier people over 230 pounds may find this mattress has a bit too much sink for them, particularly if they sleep on their stomach.
Furthermore, between the two, hot sleepers seem to be happier with the Leesa mattress, because of the level of sinkage of the Casper.
Let’s dig deeper into what makes these two mattresses great and the differences between them as we take a look at their construction, motion transfer, breathability, body compatibility and value.
The Leesa Mattress
A popular and sound choice for a foam mattress, the Leesa mattress is highly adaptive and works well with people of most body types and weights. Great for people who like the cushiness of foam, without the sinking in feeling, the Leesa makes for a cool and comfortable sleep.
What we liked:
- Great for hot sleepers
- Little motion transfer
- Good support for overweight people
- High quality construction
- Good value and warranty
What we didn’t like:
- Might not be suitable for customers who prefer thick memory foam layers
- Might be too firm for small people
- Some off gassing
The Leesa Mattress is an all foam mattress with no springs so first thing to note is, if you are making the transition from an innerspring mattress, this mattress is going to feel different from what you are used to. It has three layers of foam, starting with a six-inch layer of high density support foam on the bottom.
This high-density layer is what makes the mattress stable and makes it a good option for people who share the bed. It stays in place and is silent when another person gets in and out of the bed and turns over.
Above this is a two-inch layer of memory foam. This layer is what helps this mattress be comfortable for most sleep positions. It provides contouring and support for side sleepers and relieves pressure but at only two inches, doesn’t give too much of a sinking feeling.
The top layer is a two-inch layer of Avena foam. Avena foam is a corrugated type of foam that is meant to be more durable and higher quality than latex. The corrugated design promotes airflow and so this mattress is great for people who sleep hot and it’s a unique feature for mattresses of this type that tend to rely on cooling gel layers for keeping temperatures down.
This mattress isn’t made of natural materials and a small number of customers have reported off gassing issues that last a few days after opening.
However, overall most customers report that this smell dissipates after a while and the foams are Certi-PUR US certified to guarantee that they don’t emit harmful toxins are are bad for indoor air quality. It is on the firm end of the mattress scale, around a six or seven on a ten point with ten being the firmest, so if you are looking for that sinking feeling of memory foam, this might not be the mattress for you.
But for hot sleepers who like a bit of memory foam, and some sleep cool features, you will most likely be happy with this mattress.
The Leesa mattress performs well for people of most body types. Reviews suggest that people that move around in different positions in the night are comfortable in this bed, even if they are over 230 pounds.
The majority of customers are satisfied with purchasing the Leesa, overall with a few finding it a bit too firm and adding a mattress topper for extra comfort. This is particularly the case with smaller people under 130 pounds, who may find this mattress a bit too firm if they sleep on their side.
Similar to all foam mattresses, this mattress has some sink on the edge, so if you are someone who likes to sleep on the edge of the bed, you might want to consider if a foam mattress is right for you as innerspring mattresses tend to offer more support around the edges than foam construction. However, this doesn’t bother most people.
In terms of value, the Leesa is a fantastic buy. They offer a nice 100-night sleep trial and only ask that you try the mattress out for a minimum of 30 days.
Their warranty covers manufacturing defects for 10 years and offers full replacement in case of any problems.
They are priced very competitively for mattresses of a similar type and have a very high rating of customer satisfaction.
You Might Want To Pick The Leesa Mattress If
- You are a cold sleeper: Because the Casper mattress has slightly more of a sinking feeling than the Leesa mattress, we recommend this bed if you are often cold when you sleep. This mattress, in compared with the Leesa, has a bit more “hug” and will keep you warm when you sleep.
- You prefer the sinking feeling of memory foam: If you like a mattress with all form construction that has a bit of a sinking feeling, you’ll probably like the Casper. While not overly soft, three layers of one and a half inch pieces of foam, including a layer of memory foam sit on top of the base layer of higher density foam, and it means that you get a bit of cushiness here that you don’t get with the Leesa.
- You are average weight: This mattress is best suited for average weight or smaller people. Because it has a bit of sink to it, heavier customers find this bed has a bit too much sink and it’s not the most comfortable for overweight stomach and side sleepers. The most satisfied customers are those of average weight who sleep on their stomachs, backs or sides. Smaller customers who are under average weight find that the level of firmness is great for their hips and shoulders and they don’t have the pains that a firmer mattress gives them.

Another great mattress option is the Casper and it is one of the more popular mattresses when it comes to online purchasing due to their marketing and success through word of mouth. Like the Leesa, the Casper mattress is built from multiple layers of foam but there are some subtle differences, as we will discuss.
What we liked:
- Durable, high quality construction
- Great for average weight sleepers
- Great for people who like the sinking feel of memory foam
- Little motion transfer
- Decent warranty and sleep trial period
What we didn’t like:
- Might not be suitable for overweight sleepers
- Might not be great for hot sleepers
- People who don’t like the sinking feel of memory foam may not like this bed
- Some off-gassing smell
The base layer of the Casper is made from durable support foam and it is five inches thick as opposed to Leesa’s six inches. The next layer up is a one-and-a-half-inch layer of poly foam, with a layer of the same thickness of memory foam. These layers are topped with another one-and-a-half-inch layer of proprietary open-cell, cooling foam.
Although the the Leesa mattress only has three layers and has a slightly thicker layer of memory foam than the Casper, reviews suggest that overall, customers feel that the Casper mattress has slightly more sinkage and feels a bit softer than the Leesa mattress. This might be because of the three layers of memory foam and regular foam in the Casper, as opposed to the Leesa, which has slightly thinner top layers and a thicker layer of stable base support foam.
As well, the Leesa has a thicker base layer of support foam, which also makes it firmer. Because of this, we feel we feel, and reviews suggest, that this mattress is best for people of average size, but heavier people, over 230 pounds might feel that this mattress has too much sinkage, especially if they sleep on their sides or stomach.
Because this mattress has a bit more of a sinking in feeling than the Leesa, customers who sleep hot might find that the Casper mattress feels hotter than the Leesa, despite the fact that it has a top layer of open-cell foam.
Compared with the Leesa, which has the top layer of corrugated Avena foam, reviews show that the Leesa is a cooler bed. Like the Leesa bed, the Casper offers a ten-year warranty and a 100-night sleep trial.
Similar to the Leesa, the Casper bed is priced very competitively for multilayered mattress of a similar type and while it isn’t made of any luxury or natural materials, this mattress is a tremendous value for the quality of materials and the number of satisfied customers.

Our Verdict: Leesa Vs Casper Mattress
Really, the difference in mattresses comes down to differentiation in thickness and firmness, with the Casper having slightly more sink and being less suitable for overweight and hot sleepers.
Conversely, the Leesa bed is a bit too firm for some sleepers, particularly if they are smaller than average as they don’t have the weight to accommodate the Leesa’s level of “push back”. Overweight customers who sleep hot are happier with the Leesa which overall, has an extremely high level of customer satisfaction for people of all shapes and sizes.
Both company’s offer similar pricing and value with the same sleep trial period and warranty. They are both built with high quality certified foams and while both have some level of off gassing, they are about the same in regards to how long this lasts. Both have about the same level of motion transfer and both mattresses are great for those who sleep with a partner or for light sleepers.
Overall, while a certain degree of mattress shopping comes down to personal preference, based on customer reviews, we recommend the Leesa mattress for average and overweight customers or for customers who sleep hot and the Casper for average or lightweight customers or for those who tend to sleep cold.
