If you have narrowed down your mattress search to the Saatva and Casper mattresses, you are already in very good shape.
These are two very popular mattresses and for good reason. They are made of quality components and are both quite comfortable.
So, how do you choose between them?
I have broken these mattresses down based on their construction and who I think would benefit from each mattress. Will the Saatva or Casper be the mattress for you? Read on for my full comparison.
- They are similarly priced.
- They are both popular mattresses.
- Their customer service terms are similar.
- The Casper will be shipped in a box, but the Saatva will be hand delivered to your bedroom in an uncompressed form.
- The Saatva is a bit firmer than the Casper.
- The Casper is constructed with latex and numerous layers of foam, and the Saatva is an innerspring mattress with a pillow top.
- The Casper has a balanced foam feel, and the Saatva has a traditional innerspring feel.
- The custom slim Luxury Firm version is 11.5” tall.
- The cover is quilted with foam to create a Euro Top.
- The next layer is a thin memory foam layer.
- This is followed by a layer of individually wrapped microcoils.
- Finally, high-grade coils make up the bottom layer.
- There is a foam encasement which helps with edge support.
- The Casper is 10″ tall.
- The cover is soft and thin.
- The first layer is 1.5” of a breathable, latex-like foam.
- Next, there are 1.5” of a high-density memory foam.
- Then, there are 1.5” of a zoned transition foam.
- Finally, there are 5” of a durable support foam.

- The covers are quite different. Casper has a soft thin cover that allows you to interact with the top layers of the mattress. The Saatva also has a soft cover, but it is tufted and quilted with foam.
- 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 coils. There is 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.
- The Saatva will probably be the cooler sleeping mattress. 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. The two coil layers and durable foam, and foam encasement should ensure this mattress lasts longer than the Casper.
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. My hips sink into the pillow top but only a bit. In addition, my lumbar area is well supported.
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 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.
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.
In terms of feel, the Saava has an innerspring feel similar to what you 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 you 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.
Motion Transfer Differences
Between these two mattresses, the Casper definitely handles motion transfer more effectively. Foam is usually better at absorbing motion, so this is not surprising.
If you sleep with a partner, you should feel less of their movements on the Casper. It is the better option for couples.
See how the Saatva deals with motion transfer in the video below.
Watch how much better Casper is with motion transfer.
The Saatva has much better edge support than the Casper. 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. I also feel better lying close to the edge.
You can see the edge support differences in the photos below.
Marten is a staff writer for us. He 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:
In terms of firmness, I felt like both mattresses were a 7/10. I thought the Casper was firmer than Joe did. This is 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. 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. 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. 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 you are heavier back sleeper, either mattress could work for you. If you’re a heavier side sleeper, I would lean toward the Saatva. If you are a stomach sleeper, either could work.
In the end, it’s more about what feel you prefer. If you like a pillow top feel, the Saatva should be the better choice. If you like more of a balanced foam feel, the Casper is probably better.
As a heavier person, Marten had a much different experience than me. 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.
Pick Saatva If:
- You like traditional spring mattresses. If you like the feeling of a hotel mattress with some firmness and high-grade coils, the Saatva could work for you. It does have a luxury hotel innerspring feel.
- You are looking for a long-term investment. The Saatva features very durable materials in its construction. If you want a mattress that will last you for a long time, this could be a good choice. It is a value considering the years of use you 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.
Pick Casper If:
- You prefer a softer mattress. The Casper is definitely the softer of these two mattresses. If you don’t like too much firmness in your mattress, the Casper is the better bet.
- You prefer a balanced memory foam feel. The Casper is an all foam-mattress with soft foams in its top layers. At the same time, you are held up and shouldn’t feel stuck. If you like the feeling of memory foam, but don’t want to sink in too far, this could be a good mattress for you.
- You are a side sleeper. If you are of average weight, the Casper should give you nice pressure relief. Side sleepers should feel little pressure on their shoulders and hips.
If you consider this information, the decision between the Saatva and Casper shouldn’t be too difficult. The Saatva is a good choice if you like spring mattresses, or sleep on your back or stomach. Average weight side sleepers who like memory foam will probably feel better on the Casper. Please leave any specific comments or questions about the Saatva or the Casper in the comment section below.
