Saatva Construction

  • The custom slim Luxury Firm version is 11.5” tall and features multiple foam and coil layers.
  • The cover is quilted with foam to create a Euro Top that gives the mattress its softness and pressure relief.
  • The next layer is a thin memory foam layer that gives the mattress additional lumbar support.
  • This is followed by a layer of individually wrapped microcoils that provide additional body contouring.
  • Finally, high-grade coils make up the bottom layer and are highly supportive and durable.
  • There is a foam encasement which helps with edge support.

Casper Construction

  • The Casper is 10″ tall and features four separate foam layers.
  • The cover is soft and thin and doesn’t affect the overall feel of the mattress significantly.
  • The first layer is 1.5” of a breathable, latex-like foam that is soft and bouncy.
  • Next, there are 1.5” of a high-density memory foam that provides pressure relief and body contouring.
  • Then, there are 1.5” of a zoned transition foam that acts as a buffer between the comfort and support layers.
  • Finally, there are 5” of a durable support foam, which is a pretty standard base layer in the industry.

Construction Differences/Notes

  • The covers are quite different in feel and what they are attempting to achieve. Casper has a soft thin cover that allows people to interact with the top layers of the mattress. The Saatva also has a soft cover, but it is tufted and quilted with foam to add softness and pressure relief.
  • The Casper has a zoned construction, while the Saatva does not. These zones make the mattress firmer under key areas like the hips, but keep the rest of the mattress soft and pressure relieving. This makes it a great option for combination sleepers.
  • The Saatva has two layers of steel coils, starting with a layer of microcoils over a high-grade spring system. The microcoils help with contouring and could relieve back pain. The second layer is great for support, breathability, and durability.
  • The Saatva will probably be the cooler sleeping mattress, because the two layers of coils should allow for some good airflow. It should be much more breathable than the all-foam Casper mattress.
  • The Saatva should also be a more durable mattress without question. The two coil layers and durable foam, and foam encasement should ensure this mattress lasts longer than the Casper.

Firmness/Feel Differences

In terms of firmness, the Saatva felt like a 7/10, and the Casper felt like a 6/10. I think most average weight sleepers would agree that the Casper is the softer of these two mattresses.

On the Saatva, I felt very good support when I was on my back, because my hips sink into the pillow top but only a bit. In addition, my lumbar area is well supported because of the middle memory foam layer.

On my side, I was surprised by how well the mattress relieved pressure. The pillow top is soft, so I feel very little pressure on my shoulders and hips. I also feel well supported on my stomach.

On the Casper, I also feel excellent support on my back. The zoned construction makes it so the mattress is firmer under my hips, so they don’t sink in too far. Also, this keeps the mattress soft around my shoulders, and that gives great pressure relief when I am on my side. On my stomach, I feel decent support because of the zoned construction.

While both mattresses could be good for all positions, back and stomach sleepers should find better support on the Saatva. Side sleepers will most likely get better pressure relief on the Casper because of the zoned construction.

In terms of feel, the Saava has an innerspring feel similar to what people might find in a hotel. It has a Euro Top, which feels like a plusher pillow top. The Casper has a balanced foam feel where sleepers will sink in just a bit. Both mattresses have some bounce, so it should be easy to move around on either one.

See what I thought of the Saatva’s hotel feel in the video below.

Now, compare this to the balanced foam feel of the Casper with the video below.

Motion Transfer Differences

Between these two mattresses, the Casper definitely handles motion transfer more effectively. Foam is usually better at absorbing motion than steel support coils, so this is not surprising.

If someone sleeps with a partner, they should feel less of their movements on the Casper. It is the better option for couples who don’t want to be disturbed by their partner’s movements.

See how the Saatva deals with motion transfer in the video below.

Edge Support

The Saatva has much better edge support than the Casper, because it is a firmer mattress and foam encasement surrounds the sides of the mattress.

Sitting down near the edge the mattress, I felt more secure on the Saatva, and I also feel better lying close to the edge.

People can see the edge support differences in the photos below.

Marten’s Take

Marten is a staff writer for us and has a much different body type from me. He is 6’7″ and weighs about 230 lbs (I am 5’9″ and 160 lbs.). Here is what he thought about these mattresses and how appropriate they are for heavier sleepers:

In terms of firmness, I felt like both mattresses were approximately a 7/10. I thought the Casper was firmer than Joe did, because I press through the comfort layer and feel the firm layers beneath.

Lying on my back on the Casper, my hips sink in a little bit but not too much, and I feel the zoned support holding me up.
On my side, I am feeling some firmness on my shoulders and hips. On my stomach, I don’t feel like I am bowing in at the hips, so I feel properly supported.

On the Saatva, I felt great on my back; my hips sink into the pillow top just a bit, but I am supported overall. I feel better pressure relief on the Saatva than I did on the Casper, because the pillow top is doing a very good job of relieving pressure on my shoulders and hips. On my stomach, I also feel good support overall.

If someone is a heavier back sleeper, either mattress could work for them. If someone is a heavier side sleeper, they should lean toward the Saatva, and if someone is a stomach sleeper, either could work.

In the end, it’s more about what type of feel people prefer. If people like a pillow top feel, the Saatva should be the better choice. If people like more of a balanced foam feel, the Casper is probably better.

As a heavier person, Marten had a much different experience than me, because his weight caused him to press into the Casper more than I did. Because of this, it felt firmer, especially when he was on his side. So, he thought it wasn’t the best match for him as a side sleeper.

Who Should Pick Saatva:

  • Those who like traditional spring mattresses- If people like the feeling of a hotel mattress with some firmness and high-grade coils, the Saatva could work for them. It does have a luxury hotel innerspring feel that a lot of sleepers will be accustomed to.
  • People who are looking for a long-term investment- The Saatva features very durable materials in its construction, so if people want a mattress that will last them for a long time, this could be a good choice. It is an excellent value considering the years of use people will get out of it.
  • You are a back or stomach sleeper. The Saatva is the firmer and more supportive of these two mattresses. If you sleep on your back or stomach, you should get better support on the Saatva.

Who Should Pick Casper:

  • Those who prefer a softer mattress- The Casper is definitely the softer of these two mattresses, so if someone doesn’t like too much firmness in their mattress, the Casper is the better bet.
  • People who prefer a balanced memory foam feel- The Casper is an all foam-mattress with soft foams in its top layers but where sleepers also will feel held up and won’t feel stuck. If people like the feeling of memory foam, but don’t want to sink in too far, this could be a good mattress for them.
  • Side sleepers- If someone is of average weight, the Casper should give them nice pressure relief. Side sleepers should feel little pressure on their shoulders and hips and have a great sleeping experience.

If people consider this information, the decision between the Saatva and Casper shouldn’t be too difficult because the differences really are quite large. The Saatva is a good choice for people who like spring mattresses, or sleep on your back or stomach, while average weight side sleepers who like memory foam will probably feel better on the Casper. Consumers should read through this article a few times, assess their needs and preferences, and then make a more informed decision.
