Casper and Saatva are both online bedding companies with popular mid-range mattresses. The original Casper mattress is made with three foam layers, while the Saatva Classic mattress is made with a combination of polyfoam, memory foam, and coils. Saatva gives you three firmness choices: plush soft, luxury firm, and firm. In this review, we’re focusing on the luxury firm model.
You’ll like the Casper if you prefer the close, conforming hug of memory foam and tend not to overheat at night. It’s also a comfy choice for side and back sleepers. The Saatva is ideal for hot sleepers, back or stomach sleepers, and those who like a little bounce from their bed. We test these mattresses first-hand, so make sure to check out our testing methodology.
The Casper is an all-foam mattress that feels soft, but dense, under pressure. The Saatva is a hybrid mattress with a coil support system that has a bouncy feel. The Casper and luxury firm Saatva are both medium-firm mattresses that fall on the firmer end of the firmness scale. Each mattress helps address overheating at night: Casper with perforated AirScape foam and Saatva with breathable coils.

Check out the video below to see how Casper and Saatva stack up against each other.
Here’s how the Capser and Saatva mattresses feel for different sleepers.
The mattress firmness scale ranges from 1–10, with 1/10 being plush and 10/10 being tabletop firm. The best soft mattresses tend to conform very closely to the sleeper’s body, while firm mattresses have thinner comfort layers that minimally conform. With that said, the firmness level is relative to each individual. Heavier sleepers usually report that mattresses feel softer than advertised, while petite sleepers think they feel firmer. The Saatva and Casper mattresses are both medium-firm, with the majority of reviewers reporting a slightly firmer feel. That’s good news for stomach sleepers, who need their hips to stay lifted on top of the mattress to avoid lower back pain. Back sleepers with average-weight body types also tend to enjoy medium-firm to firm mattresses.
The Casper mattress has a soft, foamy feel where you can feel a slight sink-into sensation. Despite this, we had no problems moving around and found it to be responsive to our movements.
The Saatva, on the other hand, offers a more bouncy feel, thanks to its traditional coil-on-coil design. Unlike Casper, the Saatva mattress feels like you’re resting on top of the mattress with minimal sinkage.
The Casper Original is more suited to back sleepers, thanks to the dense polyfoam layer that spreads your body weight evenly for better support and comfort. Though a bit on the firmer side, the Casper still provides adequate zoned support for side sleepers. That said, some side sleepers may opt for something with a bit more cushion. Stomach sleepers, on the other hand, should take caution as Casper’s all-foam construction may not have enough support to keep your hips elevated. Lastly, Casper is a good fit for combination sleepers because of its responsive foam later.
The Saatva Classic comes in three firmness levels, so it’s only a matter of choosing the right one for you. Back sleepers and stomach sleepers should benefit more from the firmer levels, the Luxury Firm or Firm versions, which will give them enough support to keep your spine aligned. Side sleepers should definitely avoid the firmer ones and go for the Plush Soft version for more cushion.
Casper Performance By Body Type & Sleeping Position:
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 5 | 5 | 5 |
Average-weight (130–230 lbs): | 5 | 4 | 5 |
Heavyweight (> 230 lbs): | 4 | 3 | 3 |
Saatva Performance By Body Type & Sleeping Position:
Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
Lightweight (< 130 lbs): | 5 | 5 | 5 |
Average-weight (130–230 lbs): | 5 | 5 | 4 |
Heavyweight (> 230 lbs): | 4 | 4 | 3 |
1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent
For average weight back sleepers, both mattresses should be able to provide enough comfort and overall support for a good night’s sleep.
Most average weight side sleepers will find adequate support and cushion from both mattresses but may gravitate more toward Casper’s Zoned Support feature.
The majority of average weight stomach sleepers should find more comfort with the Saatva mattress, given the different firmness levels.
Average weight combination sleepers should also be comfortable with both mattresses. We recommend you choose the Saatva Plush Soft if your dominant position is side sleeping or the Luxury Firm version for a balanced feel.
Heavyweight back sleepers may have an easier time sleeping on Saatva’s coil-on-coil system as it should give enough support for the back. The Casper struggles a bit with heavier weight because of its all-foam construction.
On the other hand, heavyweight side sleepers may find both mattresses lacking when it comes to support and pressure relief.
The Saatva is equipped with better support for the majority of heavyweight stomach sleepers than the Casper. Stomach sleepers weighing 300 lbs and above should probably go for a firmer mattress that provides better support.
For heavyweight combination sleepers, Saatva (specifically, its Luxury Firm or Firm version) should be your choice. We don’t recommend the Casper as it doesn’t have a responsive coil system that allows easier movement.
Regardless of sleeping position, all lightweight sleepers should find no issue with both the Casper and Saatva mattresses. It all boils down to preference — if you prefer the sinking feeling in a mattress, go for Casper, but if you like the feeling of sleeping on top of a mattress, you should pick Saatva.
The Casper Original is an all-foam mattress that measures 11.5″ thick, while the Saatva classic is a hybrid mattress that ranges from 11.5″ – 14.5″. In this section, we’ll break down each mattress’s layers and see how they compare.
Casper Original Mattress Materials | Saatva Classic Mattress Materials |
Polyester blend | Euro-Top Cover (fill varies by firmness setting) |
1.5” Polyfoam 2” Memory Foam | .6” Polyfoam .4” Memory Foam |
2” Memory foam | 4” Pocketed Coils |
7” High-Density Polyfoam | Recycled Steel Bonnell Coils |
The Casper has a polyester blend cover that’s lightweight and breathable, while the Saatva features a soft organic cotton cover that’s coated with an all-natural antimicrobial treatment called Guardin.
Casper’s support layers consist of a polyfoam top layer (made out of their proprietary Casper Airscape foam) and a second layer made out of memory foam, which provides the Zoned Support system.
Saatva has a polyfoam top layer that differs depending on the firmness level. This is followed by a memory foam layer for added support and contouring.
The Casper has a memory foam support layer that’s firmer than the rest of the layers and acts as the foundation for the bed. The simple base layer is made of support foam.
The Saatva has two coil layers — a top layer consisting of small, individually pocketed coils and a bottom layer that’s made of sturdier steel coils. A thin layer of memory foam separates the two coil systems, while a dense foam layer lines the mattress edges.

Do you kick your covers off every night or sweat through your sheets often? You might need a cooler mattress. The best mattresses for hot sleepers have a breathable construction and incorporate various cooling technologies.
Casper uses “open cell” Airscape foam in their mattress, which includes perforation in the foam to enable better airflow. The Casper should help slightly hot sleepers sleep temperature-neutral, especially compared to other all-foam beds. The coil layers in the Saatva mattress create a lot more open space for cool air to flow, so it’s a better option for hot sleepers.
Does your sleeping partner love midnight snacks? Then this performance category is for you. Motion isolation is the measurement of how well a mattress keeps movement isolated at its source. Memory foam mattresses usually do the best job of absorbing motion, while innerspring mattresses are notoriously bouncy and squeaky, transferring motion readily across the surface of the bed.
Predictably, the Casper does a better job of reducing motion transfer. That’s not to say couples won’t be able to sleep easily on the Saatva, but if motion transfer is a priority for you, Casper is the better choice.

Edge support is an important factor to consider if you sit on the edges of your bed often or if you sleep close to the sides of the bed. Both of these mattresses have reinforced perimeters: Casper has a dense base layer that prevents sinkage, and Saatva is framed with high-density foam. We think the Saatva is a little better at supporting edge dwellers, but both mattresses performed well in this category.
If you sleep predominantly on your side, you need a mattress with lots of pressure relief. Putting too much weight on your curvier bits can strain your spine, shoulders, hips, and neck. The best mattresses for side sleepers compress easily around pressure points but aren’t so soft that you lose the natural “S” curve of your spine.
Casper is the clear winner in this category. Casper’s all-foam construction offers more pressure relief than Saatva’s coil layers and pillow top. Still, the Saatva may still be in line with your comfort level if you’re an average or plus-sized combination sleeper who spends time on your side.
When it comes to mattresses, pressure and pain often have a cause-and-effect relationship. The more pressure you put on your spine, the more it builds up, and eventually turns into chronic back pain.
If you have chronic pain, both mattresses perform well when it comes to providing support and relief for your back. Casper’s all-foam construction does just a bit better by relieving more pressure.
Mattresses are designed to perform at optimal levels for at least seven years, and ideally 10 years. Some mattresses are more durable than others, and high-quality materials don’t always make a difference. Typically, latex mattresses last the longest, and innerspring mattresses deteriorate the fastest. Hybrid beds, like the Saatva, tend to keep their shape a little longer than foam beds, but the difference shouldn’t be more than a year or two.
Casper provides free shipping 1-2 days after placing your order (with extra fees for deliveries to Alaska and Hawaii). They also offer a 100-sleep trial period, with free returns and a full refund. You’ll also get a 10-year warranty with your mattress, which includes free repair or replacement in case of defects.
Saatva offers free white glove delivery that comes with old mattress removal. Unfortunately, they don’t ship to Alaska or Hawaii, but freight forwarding is an optional extra cost. They also provide an extensive 365-day sleep trial and a lifetime warranty, eligible only to the original mattress owner. With it, you get free replacements during the first two years and discounts for repair and replacement.

Both mattresses are really comfortable and bring something different to the table for different sleepers. Both beds are great if you’re sleeping alone, but couples may want to go for the Casper Original mattress for better motion isolation. Back and side sleepers will probably sleep better on the Casper, while Saatva offers better firmness and support for stomach sleepers, particularly the Luxury Firm or Firm versions.
Yes, Casper mattresses are designed to last up to 8 to 12 years. Durability aside, proper care and maintenance should also be followed if you want your mattress to last.
All mattresses will eventually sag with time. If you sleep in one position or area, then that side may experience sagging. You can rotate your mattress to avoid this, but don’t flip it as Casper mattresses are made of strategically layered materials.
Yes, it will eventually sag, as all mattresses do. To prevent this, you can rotate your Saatva mattress every six months to distribute the wear and tear to other areas.
No, all Saatva mattresses are constructed and made from materials that are sourced from the U.S.
