Casper vs. Saatva Mattress Comparison

Casper and Saatva are two polar opposite mattresses, and we’re here to help you navigate choosing between the two.

Comparing Casper & Saatva Mattresses

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. 


  • 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.
  • We think the Casper is ideal for combination sleepers, especially those who tend to flip from their back to their side. The Saatva is better for back and stomach sleepers.
  • Because it’s an all-foam bed, the Casper sleeps warmer than the Saatva.


  • 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.

Who Is the Casper Mattress Best For? 

Best For…

  • Back sleepers fare the best with a blend of support and contouring cushion, and the medium firmness of the Casper offers both. 
  • Those with back pain will notice that their spinal alignment (and possibly even their posture) improves on the Casper, which reduces the likelihood of developing muscle aches.
  • Combination sleepers won’t feel stuck in the Casper mattress, thanks to its responsive foam layers.

May Not be Best For…

  • Heavyweight stomach sleepers need a little more support than the Casper can give them, though average sized stomach sleepers may find enough support. 
  • Hot sleepers should instead opt for the Casper hybrid mattress model, which includes a breathable layer of coils.

Who Is the Saatva Mattress Best For? 

Best For…

  • The two layers of coils in the Saatva mattress keep stomach sleepers hips lifted above the mattress surface, which can help prevent lower back pain.
  • Seniors need a mattress that keeps their spines in a healthy, natural “S” curve, and the Saatva delivers. Plus, it has good edge support for those who need stability getting in and out of bed.
  • Back sleepers will experience an ideal combination of cushioning and support on the Saatva.

May Not be Best For…

  • Side sleepers may not get enough pressure point relief on the Saatva, even with its 3” thick pillow top layer.
  • Light sleepers who sleep with a partner are likely to be disrupted a partner’s movement on the Saatva mattress.

Deciding Between Casper & Saatva

Firmness / Feel

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, 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.

Motion Isolation

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

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.

Pressure Relief 

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.

Spine Alignment 

The term “spinal alignment” is a fancy way of saying “good posture in bed.” Whether you sleep on your back, side, stomach or a combination of all three, you’ll notice fewer aches and pains if your spine stays in a neutral position during the night. Our team was impressed by how well both beds in this mattress comparison kept our testers’ spines in alignment. Both do a near-perfect job of helping you maintain good posture while you sleep.


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 the 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.


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.

Casper vs. Saatva: The Casper (left) is compared to the construction of the Saatva (right).

Casper Mattress Construction 

Cover Polyester blend
Comfort Layer  1.5” polyfoam

2” memory foam

Transitional Layer 2” memory foam
Support Layer 7” high-density polyfoam
Mattress Thickness  11”

The Casper mattress has a simple construction made of three layers of foam. Each layer is intentionally designed to maximize pressure relief and improve breathability. The top layer is Casper Airscape foam—a soft, open-cell foam that prevents heat from getting trapped in the comfort layer

The support layer is made of memory foam divided into three ergonomic zones. You’ll notice more support under your lower back and hips and more cushioning under your shoulders. The simple base layer is made of support foam.

Saatva Mattress Construction

Cover Euro-top cover (fill varies by firmness setting)
Comfort Layer  .6” Polyfoam

.4” Memory foam

Transitional Layer 4” pocketed coils
Support Layer Recycled steel bonnell coils
Mattress Thickness  11.5” or 14.5”

The Saatva mattress is wrapped in a soft organic cotton cover that’s coated with an all-natural antimicrobial treatment called Guardin. This treatment helps to cut down on germs and odors that can accumulate on the mattress. When you lie down, you immediately sink a few inches into the euro pillow top. This topper is padded with a 3” layer of polyfoam that conforms to your body and forms a barrier between you and the first coil layer.

The Saatva is anchored by a dual coil system. The top layer is made of small pocketed coils with targeted motion isolation and pressure relief. The second layer is made of sturdier steel coils. In between the two, a thin memory foam layer and wire frame give you an extra boost of lumbar support. Finally, dense foam lines the edges of the mattress and helps improve edge support.

Our Casper vs. Saatva Final Review

These are both really comfortable beds, but if sleeping cool is your main priority, the Saatva is the better option. If you have back pain or sleep on your side, the Casper is probably your best bet. Back sleepers will fare well on either mattress, but stomach sleepers should go with the Saatva, particularly the luxury firm or firm versions. Lastly, couples will achieve significantly better motion isolation on the Casper mattress.
