Casper and Leesa are two of the leading mattresses on the market. They both have a lot to offer but also some differences. We’ll look at how each of them stacks up against the other and let you know which one is right for you. You could also read more about the mattresses we review through our testing methodology.
At first glance, you may think that Casper and Leesa have very similar features. In this review, we’ll look over their differences and similarities to figure out which brand suits your needs best.

In this video, we compare Casper and Leesa mattresses to help you decide which is best for you. We’ll talk about how each mattress feels and its pros and cons so you can decide which is right for your needs.
In this section, we’ll walk you through the differences between Casper and Leesa mattresses in terms of firmness levels and feel.
Share the firmness levels of each mattress, and then address how those firmness levels will feel for different body types (lightweight, average-weight, and heavyweight). Although the Leesa and the Casper mattresses have very comparable firmness levels, their textures feel very different.
The top of the Leesa mattress is designed to let the sleeper’s body sink in slightly further, giving the impression that one is sleeping “in” rather than “on” the surface of the mattress. Although the top layer of the Casper mattress is also very soft, the zoned layer of memory foam that lies beneath it results in significantly less sinkage and significantly more support along the lower back and hips. Because of this, Casper has a feeling that is somewhat more balanced and less conforming overall.
Although people who weigh less than 230 pounds and sleep on their back, stomach, or side are likely to enjoy either mattress, we believe that lightweight side sleepers and heavier stomach sleepers are better supported on the Casper. Back sleepers who weigh more than 230 pounds will likely enjoy the Leesa. Because it has a Zoned Support layer, it provides increased cushioning for those who sleep on their sides and additional support for those who sleep on their stomachs.
Casper Performance By Body Type & Sleeping Position:
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 5 | 4 | 4 |
Average-weight (130–230 lbs): | 5 | 3 | 5 |
Heavyweight (> 230 lbs): | 3 | 2 | 2 |
Leesa Performance By Body Type & Sleeping Position:
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 5 | 4 | 4 |
Average-weight (130–230 lbs): | 5 | 3 | 3 |
Heavyweight (> 230 lbs): | 2 | 1 | 2 |
Leesa and Casper are excellent options if you’re an average weight and prefer to sleep on your side, back, or combination position (where one elbow is propped up). That’s because Leesa and Casper mattresses have softness layers that provide side sleepers, stomach or back sleepers, and combination sleepers pressure relief to your hips and shoulders and firmness layers that support your body weight evenly across the mattress surface. This allows for optimal spinal alignment during sleep, making breathing deeply and relaxing into a restful slumber easier.
Leesa and Casper mattresses are not the best options for heavy-weight sleepers. When it comes to side sleepers, they can feel like they’re sinking in too much and getting trapped between the mattress and the bed frame. Back sleepers may find that these mattresses don’t provide enough support for their backs. Stomach sleepers also may experience issues with these mattresses, as they tend to be more firm than soft. Combination sleepers may find that these mattresses are too firm for their liking.
If you’re a lightweight sleeper, especially if you are a side sleeper or back sleeper, then Leesa and Casper mattresses are the way to go. Your body weight is distributed evenly across the mattress, so you’ll feel supported without feeling smothered by too much pressure on your body. This also helps to prevent pressure points from forming along your hips and shoulders—which can cause discomfort during sleep.
Let’s look at the differences between the Leesa and Casper mattresses’ construction in terms of cover, comfort, and support layers.
Casper Mattress Materials | Leesa Mattress Materials |
Soft, breathable cover | Twill mattress cover |
(2“) Airscape foam | Breathable, bouncy foam |
(2“) Zoned Support layer | Memory foam layer |
(7“) High-density base | High-density foam |
11” | 11” |
The cover on a Casper mattress is soft, breathable, and made of polyester. This cover is designed to help you stay cool and comfortable while you sleep. The Leesa mattress has a Twill cover, which is also breathable but much more durable than Casper’s softer fabric. It’s also made from cotton and polyester.
In terms of comfort layers, the Casper mattress has a 2“ Airscape foam made of polyurethane and designed to work as both an airflow channel and an aeration layer that allows for increased airflow, which in turn helps with temperature regulation and body support. Meanwhile, Leesa has a breathable, bouncy foam made from polyester and latex, which I designed with a lot of bounce back so that you’ll feel less pressure on your body when you’re sleeping on it.
Casper has a 2″ zone support layer, while Leesa uses memory foam. This means that Casper’s construction provides support throughout the entire mattress, while Leesa’s is designed to cradle your body in its most comfortable position.
Size | Casper Prices | Leesa Prices |
Twin | $895.00 | $849.00 |
Twin XL | $995.00 | $899.00 |
Full | $1195.00 | $1099.00 |
Queen | $1295.00 | $1299.00 |
King | $1695.00 | $1599.00 |
California King | $1695.00 | $1599.00 |

In this section, we’ll describe how the two mattresses compare in temperature, motion transfer, edge support, durability, pressure relief, and pain relief. This will help you distinguish which mattress fits your needs best.
Both Leesa and Casper use breathable polyfoam along the top layer to store less body heat than the average memory foam mattress. However, neither bed is as excellent as most beds with a layer of innerspring coils. While both beds are suitable for people who don’t struggle with sleeping hot, the Casper is just a touch cooler. The Leesa mattress hugs the body closer and stores more body heat throughout the night.
For a more restful night’s sleep, those who share their bed with a significant other, a pet, or even a child need a mattress that can absorb motion from the other occupants. Leesa and Casper mattresses are made entirely of responsive foam, which means that they are not particularly effective at reducing motion transfer. As a result, neither one is a wise choice for people who share a bed and are light sleepers.
Although both the Leesa and the Casper beds provide the necessary level of edge support, the Casper is more supportive for sitting on the edges of the bed than the Leesa is. This makes it possible to lie along the edges of both beds without feeling unsafe or uncomfortable. It’s possible that the Casper would work well for you if you get in and out of bed by grabbing the side of your mattress.
The Casper’s Zoned Support foam is designed to provide a more supportive feel at the shoulders than the Leesa. While it’s also great for lightweight side sleepers, you won’t get as much pressure relief in the shoulders if you’re an average-weight side sleeper.
The Leesa’s conforming memory foam surface supports the spine of back sleepers exceptionally well. It also supports a healthy spine for medium-heavyweight side sleepers who weigh more than 130 lbs and stomach sleepers who weigh less than 130 lbs. Meanwhile, the Casper is one of the few beds that does an exceptional job providing proper spinal alignment, no matter your sleeping position. Because the Casper has three ergonomic support zones, the bed should offer good spinal alignment for side, back, and stomach sleepers who weigh less than 230 lbs.
Compared to the Leesa mattress, the Casper mattress has a slightly longer lifespan. The Casper is less likely to form body impressions or soften as quickly as the Leesa due to the firmer foam located along the middle third of the bed. This is the area of the bed where the heaviest parts of the body tend to rest.
Casper mattresses are free to most of Canada and the 48 continental states, but Alaska and Hawaii have a shipping fee. Their mattresses can be returned any time during the first 100 nights or trial period, and full refunds are available. Moreover, Casper offers a 10-year warranty on defects in materials or workmanship.
Leesa is the bed-in-a-box brand that ships mattresses compressed into a box, including delivery to Hawaii and Alaska. If you’re not ready for a new mattress yet, no problem—Leesa offers a trial period of 100 nights, then donate it to charity if you decide it’s not right for you. It also comes with a 10-year limited warranty wherein Leesa pays to repair or replace your mattress if you experience a covered defect, including body impressions greater than 1” deep.

The Leesa’s thicker comfort layers mean a closer cradling feel that’s great for anyone who likes to be hugged by their mattress. The Casper’s Zoned Support layer gives sleepers superior support and cushioning, making it a better option for people with back or joint pain. Both beds come with a risk-free 100-night trial periods and easy returns, removing most of the stress that comes from buying a new mattress online. They also both made our list of best mattresses in 2025, so you can count on a good night’s sleep on either bed.
If you’re looking for a comfortable, supportive, and affordable mattress, either of these is a solid choice. The Leesa is an excellent match for lightweight back sleepers and people who need pressure relief around their shoulders. The Casper is better for combination sleepers and heavier people who need more support.
Casper has a lower price point than Leesa, but if you’re a side sleeper or back sleeper and want to sink into the mattress a bit more, Leesa might be the better option. Both companies offer trials, so if you can try it out before committing to it.
When it comes to softness, Leesa is probably the more comfortable mattress. This means it should provide plenty of pressure relief for side sleepers who don’t want to feel jammed up around the shoulder. We also found that Casper offered decent pressure relief for side sleeping.
