Deciding between two quality mattresses like the Layla and Casper can be difficult. These all-foam mattresses have a lot to offer different types of sleepers.
To make your decision easier, I have broken these mattresses based on their constructions and who I think would benefit more from one or the other.
This comparison will go through the construction of both mattresses in detail and highlight the main takeaways consumers should know about before making a purchase.
- They are both all-foam mattresses.
- They are both 10” thick.
- They both incorporate memory foam somewhere in their construction.
- The Layla is flippable, and the Casper is not.
- The Casper has zoned support, and the Layla has a more uniform feel overall.
- Layla has memory foam in its top layer, and Casper has it in its second layer.
- Layla has a classic memory foam feel, and the Casper has a balanced foam feel.
- The Casper is firmer than the Layla.
- The cover is infused with Thermogel to help with cooling but doesn’t affect the feel of the mattress significantly.
- From the soft side down, first, there are 3” of a copper-infused memory foam, which is very soft and has great pressure relief.
- Next, there are 2” of a convoluted support foam, which has channels to help with airflow.
- The support layer is 4.5” of a 2 lb. base foam, which is a pretty standard base layer in the industry.
- On the firm side, there is 1” of copper-infused memory foam, which is the same material used in the soft side of the mattress.
- The cover is soft and thin and doesn’t affect the overall feel of the mattress too much.
- The first layer is 1.5” of a breathable, latex-like foam, which gives the mattress softness and resilience.
- Next, there are 1.5” of a high-density memory foam, which gives the mattress great body contouring.
- Then, there are 1.5” of a zoned transition foam, which is firmer in the middle part and softer underneath the shoulder area.
- Finally, there are 5” of a durable support foam, which is a pretty standard base layer on the market.
- Both mattresses have soft thin covers that make it easy to feel the layers beneath.
- The transition layer of the Casper has zones that will be firmer, which means it is firmer under key areas of the body. The Layla does not have this and instead has a more uniform feel.
- The Layla is flippable, so there is a soft side and a firm side, while the Casper is not.
- The Layla has memory foam in its top layer, while the Casper has it in its second layer. This gives the Layla a more classic memory foam feel and the Casper a more balanced foam feel.
- Both these mattresses should be good at keeping people sleeping cool throughout the night. They are both breathable mattresses, but the Casper may be a bit better with cooling. It has an open-celled top layer which will make it more breathable than that top memory foam layer on the Layla.
- They should both be about the same in terms of durability.
For me, the soft side of the Layla was a 5.5/10, and the firm side was closer to an 8/10. The Casper felt more like a 6/10 in terms of firmness, so I definitely think the Casper is the firmer than the soft side of the Layla.
The Casper also has a zoned construction, which means that it is firmer under heavier areas like the hips. At the same time, under the shoulders, the mattress is softer and more pressure-relieving.
Because of this, the Casper felt better when I was on my back and stomach, as that zoned support kept my hips from sinking and taking my spine out of alignment.
I did feel nice pressure relief on the Casper, but I think the Layla was better in this position, as I felt very good pressure relief on the shoulders and hips.
In terms of feel, the Layla has more of a classic memory foam feel that resembles quicksand. Lying on the mattress, I slowly sink and sleep more “in” the mattress. The Casper has a balanced foam feel in which I sleep “on” the mattress, and as a result it is easier to move around on the Casper.

Motion Isolation Differences
Memory foam is usually quite good at preventing motion transfer because of its chemical nature. Since the Layla has memory foam in its top layer, I expected the motion isolation to be better than the Casper.
Between the two mattresses, the Layla indeed better motion isolation because of the thickness of memory foam used in the construction. People should feel less of their partner’s movements on their side of the mattress. Because of this, the Layla could be the better mattress for couples who don’t want to be disturbed by their partner’s movements.

The Casper is a bit firmer than the Layla and doesn’t have that super soft memory foam on top, which helps give it better edge support in my opinion.
Sitting on the side, I felt more secure when I leaned over to tie my shoes. Also, with the Casper, I felt like I could lie closer to the edge without falling off.

Marten is a staff writer for us and has a much different body type: He is 6’7″ and weighs about 230 lb; I am 5’9″ and 160 lb. Here is what he thought about these two mattresses and how appropriate they are for heavier sleepers.
I felt like the Layla was a 6/10 for firmness, and the Casper was more like a 7/10.
On the Layla, I felt better on my side and felt good pressure relief on the shoulders and hips. Between the two mattresses, when I was on the Casper I felt better on my stomach and back, perhaps because of the zoned construction.
So, if someone is my size and a side sleeper, they should lean toward the Layla. If someone is my size and a back or stomach sleeper, between the two, they should choose the Casper.
While Marten found both mattresses to be a bit firmer, he did agree that the Layla was the softer of the two mattresses. Because of this, he actually came to similar conclusions about this mattress. The Layla was the better pick when he was on his side, and the Casper was better when he was on his stomach and back. I think that zoned support really went to work for him on his back and stomach.
Who Should Pick Layla:
- Those who prefer a softer mattress- The Layla has two sides, and the soft side is definitely softer than average without question. If someone likes a mattress with extra pressure relief, this could be a good choice.
- People who are primarily a side sleepers- The soft side of this mattress does a good job of relieving pressure on the shoulders and hips. If someone mainly sleeps on their side, this should be the better pick for them.
- Those who prefer a classic memory foam feel- If someone likes to sink into their mattress and sleep more “in” your mattress rather than “on” the Layla should be better for them. It has that soft, quicksand-like feel that comes with classic memory foam.
Who Should Pick Casper:
- Those who prefer a medium-firm mattress- While it is not very firm, the Casper is definitely firmer than the Layla without question. If someone needs a bit more support, this might be the mattress to go with.
- Back or stomach sleepers- The mattress is designed to be more supportive under key areas like the hips. If someone sleeps primarily on your back or stomach, this firmer mattress with its zoned support may be better for them.
- People who prefer a balanced foam feel- If someone likes a foam feel where it is still easy to move around on the mattress, the Casper may work for them. People will have less of that feeling of getting “stuck” on this mattress.
Both of these mattresses could be a great choice, depending on what kind of sleeper someone is and the type of feel they are looking for. If someone sleeps on their side or likes a classic memory foam feel, they should choose the Layla, but if someone sleeps on their back, stomach, or prefers a balanced foam feel, the Casper could be the way to to go.
