by Casper wins for back sleepers who want targeted zoned support. Leesa is the better fit for combination sleepers who want a uniform pressure-relieving feel at a slightly lower price. Both are solid all-foam bed-in-a-box options, but neither matches the support, trial length, or white-glove delivery you get from Saatva Classic, which is why we rate it above both. If budget is the deciding factor, the Puffy Cloud gets you a similar all-foam feel with a longer trial for less.
Saatva Classic
9.4/10
- Dual-coil construction with reinforced lumbar zone, more support than either foam alternative
- Outstanding edge support and cooling, far better airflow than all-foam
- Free white-glove delivery, setup, and old mattress removal
- 365-night trial, lifetime warranty, no-fee returns in most cases
- Moderate motion isolation, coil bounce transfers more than foam
- Heavy, not compressed in a box, ships fully assembled
If you are comparing Leesa and Casper but can stretch the budget slightly, the Saatva Classic in Luxury Firm gives you longer trial, better edge support, and a traditional coil feel that outlasts both all-foam competitors.
Puffy Cloud
8.7/10
The Puffy Cloud delivers the same all-foam, pressure-relieving feel that draws shoppers to Leesa and Casper, usually at a lower sale price for a queen. Its 365-night trial and lifetime warranty also beat the 100 nights and 10 years both brands offer.
Leesa vs Casper: who wins?
Both Leesa and Casper are legitimate bed-in-a-box foam mattresses with solid reputations, but they are built differently and serve different sleeper types. Casper uses a three-zone ergonomic support layer that firms up under the hips and lumbar, which is the right call for back sleepers who need spinal alignment. Leesa uses a more uniform foam stack that distributes pressure evenly across all zones, making it the better pick for combination sleepers and people who change positions through the night.
At their respective price points, Casper runs slightly higher on the queen but both frequently go on sale near $995. The real gap shows up in long-term durability: all-foam mattresses at this price tier typically show body impressions within 4 to 6 years, which is why we consistently recommend investing a bit more in a dual-coil hybrid like the Saatva Classic if your budget allows.

Construction: how each mattress is built
Leesa Original
The Leesa Original is a 10-inch all-foam mattress with three layers. A 2-inch breathable cooling foam sits on top to manage surface temperature. Below that is a 2-inch contouring memory foam layer that provides pressure relief at the shoulders and hips. The base is a 6-inch high-density support foam that anchors the whole structure. There is no zoning, which means the feel is consistent from head to foot, a design choice that suits combination sleepers but gives back sleepers less targeted lumbar firmness than some people need.
Leesa also offers hybrid versions (Original Hybrid, Sapira Hybrid, Legend Hybrid) that add pocketed coils for extra responsiveness and edge support. Those are worth considering over the all-foam Original if you share a bed or sleep warm.
Casper Original
The Casper Original is an 11-inch all-foam mattress with a more deliberately engineered support layer. Casper calls it AirScape Zoned Support: the foam is softer under the shoulders and firmer under the hips and lumbar zone, which helps keep the spine aligned for back and side sleepers. The top cooling layer includes perforated foam for airflow, which Casper markets as AirScape. The base is a high-density support core.
Casper also has hybrid options (Original Hybrid, Nova Hybrid, Wave Hybrid Snow) at higher price points. The Wave Hybrid Snow adds a gel cooling layer and a more aggressive zoned foam system, but it pushes the queen price above $2,000, which is a different conversation entirely.
Firmness and feel
In independent testing, the Leesa Original scores around 5.5 out of 10 on firmness, which puts it squarely in the medium range. The feel is described consistently as pressure-relieving and contouring without excessive sinkage. Side sleepers generally land comfortably on it because the memory foam distributes shoulder pressure well.
The Casper Original scores around 6 out of 10, slightly firmer than Leesa overall. More importantly, the feel changes depending on where you lie: softer under the shoulders, firmer under the hips. Back sleepers and heavier side sleepers often find this preferable. Stomach sleepers, however, may find Casper's zoning actually creates too much firmness at the pelvis, making it feel uneven.
Motion isolation and edge support
Both mattresses perform similarly on motion isolation. All-foam construction absorbs movement well, so a restless partner is less likely to disturb you than on a coil bed. Leesa's memory foam layer is slightly better at deadening motion than Casper's zoned support layer, though the difference is minor.
Edge support is a shared weakness between them. Sitting on the edge of either mattress produces noticeable compression, and the sleeping surface shrinks meaningfully from the perimeter. Couples who spread out or who get in and out of bed frequently may find this frustrating over time. This is where both lose ground to any coil-based mattress, including the Saatva Classic, which uses reinforced perimeter coils that hold the edge firm.
Cooling and temperature
Leesa's top layer uses a breathable open-cell foam that allows some airflow, but like most all-foam mattresses, it retains more body heat than a coil-based design. The memory foam layer in particular tends to trap warmth around the sleeper's body. Hot sleepers should know this going in.
Casper's perforated AirScape foam does slightly better at moving air through the mattress. The perforations allow heat to dissipate more actively than a solid foam layer. Still, even Casper's best all-foam construction runs warmer than a hybrid with open coil chambers. If cooling is a top priority, both mattresses are adequate for average sleepers but not ideal for hot sleepers.
Price and value
On list price, Leesa comes in slightly cheaper across most sizes. Queen-to-queen, Leesa lists at around $1,199 versus Casper's $1,295, though both brands run frequent promotions that can bring either close to $995 on a sale. Both offer 100-night trials and 10-year warranties, which puts them on equal footing for risk management.
For context, the Saatva Classic starts around $1,695 for a queen but includes free white-glove delivery and setup, a 365-night trial, and a lifetime warranty. For $500 more than a sale-price Casper or Leesa, you are getting a longer trial window, better durability (coil construction), and removal of your old mattress. That is a different value proposition, not just a higher price tag.
Who should buy Leesa?
- Combination sleepers who move through multiple positions during the night
- Side sleepers under 200 pounds who want pressure relief at the shoulder and hip
- Couples who sleep at similar temperatures and want a consistent, predictable foam feel
- Buyers on a tight budget who want a reliable all-foam mattress under $1,200 list price
Who should buy Casper?
- Back sleepers who want zoned lumbar support from a foam bed
- Side sleepers who run warm and appreciate the perforated AirScape layer
- Buyers who want slightly more targeted ergonomic support than a uniform foam stack provides
- People who have tested Casper in a showroom and liked the firmer-at-the-hips feel
Frequently asked questions
Is Leesa or Casper better for back pain?
Casper's zoned support layer firms up under the lumbar zone, which gives it a slight edge for back pain caused by poor spinal alignment. Leesa's uniform foam feel is better at pressure relief but does not actively reinforce the lumbar. For serious back pain, both fall short of a properly zoned hybrid like the Saatva Classic or a dedicated lumbar-support mattress.
Which is softer, Leesa or Casper?
Leesa is marginally softer overall, scoring around 5.5 out of 10 versus Casper's 6 out of 10 in independent testing. The difference is subtle, but side sleepers who want more give at the shoulder tend to prefer Leesa, while sleepers who want a bit more pushback choose Casper.
Are Leesa and Casper good for couples?
Both are decent for couples. Motion isolation is a strength for all-foam mattresses, so a partner moving at night is less disruptive than on a coil bed. The weakness for both is edge support: the sleeping surface narrows near the perimeter, which can feel restrictive for two people sharing a queen. A hybrid mattress with reinforced edges solves this problem.
How does Saatva compare to Leesa and Casper?
Saatva Classic is a dual-coil hybrid, meaning it has two layers of steel coils with foam comfort layers above. This gives it better durability, superior edge support, and more cooling airflow than either all-foam option. The trade-off is price (queen starts around $1,695) and reduced motion isolation compared to foam. Saatva also includes free white-glove delivery, a 365-night trial, and a lifetime warranty, which neither Leesa nor Casper offers.
Do Leesa and Casper have fiberglass?
Leesa uses a thistle-based flame barrier and is fiberglass-free. Casper has not publicly disclosed its flame barrier composition as of 2026, and some consumer reports have raised questions about its liner material. If fiberglass-free certification matters to you, verify directly with Casper before purchasing, or choose a brand with explicit third-party certification.
Saatva Classic
If you are still torn between Leesa and Casper, the Saatva Classic is the mattress we would price out first: dual-coil support, a 365-night trial, and free white-glove delivery that neither foam bed matches.
