Saatva Vs Casper Mattress Overview
The Saatva is an innerspring mattress that features nice components such as organic cotton, micro-coils, and supportive coils – it comes in three firmnesses, and we reviewed the Luxury Firm model.
The Casper Original is available in all-foam and hybrid models, and we reviewed the all-foam model. It is an innovative mattress with a zoned construction that offers an excellent balance of comfort and support. In fact, we named it one of the best bed-in-a-box mattresses!
The Saatva and Casper both have a lot to offer, but they are a better fit for people with different sleep preferences.
Who Should Get The Saatva?
- Those who want to try one of the best innerspring mattresses with a pillow top
- Stomach sleepers and back sleepers who are in need of extra support
- Those who are looking for a durable, longer-lasting mattress
Who Should Get The Casper?
- Side sleepers who need a mattress to relieve pressure on their shoulders and hips
- Those who prefer an all-foam mattress with a balanced foam feel
- Shoppers who want to spend a bit less money on their mattress purchase

Similarities Between The Saatva And Casper?
Now, let’s discuss the major similarities between the Saatva and Casper mattresses:
- The Saatva and Casper are both popular, best-selling online mattresses
- Saatva and Casper both offer competitive sleep trials, warranties, and customer service terms.
- The Saatva and Casper mattresses both feature memory foam somewhere in their design.
- They are two of the best mattresses for back sleepers.
- Both mattresses feature some sort of zoning, so they will feel firmer or softer depending on one’s sleeping position.
Differences Between The Saatva And Casper?
The Saatva and Casper are really more different than they are alike; let’s see what the significant differences are:
- The Saatva is an innerspring mattress, and the Casper Original is an all-foam mattress with no coils.
- The mattresses have a very different feel – the Saatva has a classic, bouncy innerspring feel, and the Casper has a balanced foam feel.
- The Saatva mattress is more breathable than the Casper Original all-foam mattress.
- The Saatva mattress should be more supportive than the Casper mattress.
- The Casper mattress costs less than the Saatva mattress.
- The Saatva comes with free White Glove Delivery, and the Casper will come shipped in a box.
Firmness And Feel Differences
As we saw above, the Saatva and Casper have some very different designs and this affects their overall firmness and feel. We will now talk about just how firm these mattresses are, what they feel like, and how this will differ for average, light, and heavyweight sleepers.
How Firm Are The Saatva And Casper Mattresses?
In our experience, the Saatva felt like a 7/10, just a bit firmer than average. Again, we will note that this is the Luxury Firm model – the Plush Soft model will feel softer, and the Firm model will feel firmer. With the Luxury Firm Saatva mattress, there is some plushness on top as a pillow-top mattress, but it gets much firmer beneath that.
The Casper Original mattress also felt like a 7/10 – the top polyfoam layer is quite soft, and then the mattress is firmer the deeper we press in. Also, because of the Zoned Support system in the second layer, the Casper will feel noticeably firmer and more supportive when people are back and stomach sleeping and softer when they are side sleeping.
Also, as with any mattress, the firmness of the Saatva and Casper will depend greatly on the size and weight of the sleeper. A larger person might feel like both mattresses are softer than we did, and a lighter person might feel like they are softer. Below, we will get into more detail on how these mattresses will feel for people of different sizes.
Sleeping On The Saatva And Casper Mattresses
Back sleeping on the Luxury Firm Saatva mattress, we are experiencing a nice balance of comfort and support. Our hips sink into the pillow top, and we also feel extra lumbar support from the zoning in the mattress. Also, with its two sets of coils, the Saatva mattress is providing an excellent amount of support.
Side sleeping on the Saatva mattress, we are feeling a bit of pressure on our shoulders and hips. Side sleepers who are medium-weight or lightweight should feel decent pressure relief on the Luxury Firm mattress. Heavier side sleepers might want to consider the Plush Soft model for better pressure relief.
Stomach sleeping, the Saatva mattress is offering decent support – it does feel firm enough to support us under our hips. Of the two, it is the best mattress for stomach sleepers. That being said, larger stomach sleepers might want to consider the Firm model or another firm mattress altogether.
The Casper is also a good match for us when we are back sleeping – the firmer area of the Zoned Support layer is providing extra lumbar support under our hips, and the base support foam is holding up our bodies well. We don’t quite feel the same overall support we received on the Saatva, however.
Side sleeping on the Casper, the mattress is a good fit for us because the shoulder area is significantly softer than the lumbar area. We feel little pressure on our shoulders and hips, but much larger side sleepers might still need a softer mattress.
Stomach sleeping, the Casper is not giving us quite enough support under our hips, so we are bowing in there somewhat. Even with its Zoned Support System, the Casper is not supportive enough for us in this position.
What Do The Saatva And Casper Mattresses Feel Like?
The Saatva mattress has a traditional innerspring feel and boasts a good bit of bounce. With the pillow top, it also has a somewhat plush feel on top of the mattress. That being said, it feels like we are sleeping “on top” of the mattress without sinking in too far.
The Casper mattress has more of a balanced foam feel that is both soft and responsive. We sink into the Casper more than we do on the Saatva, but we have no real issue moving around or changing positions.
Average Weight Sleepers – 130 lbs – 230 lbs
Average weight back sleepers should feel comfortable and supported on both the Saatva and Casper mattresses. They should feel their hips sink in the right amount, and they should receive proper overall support and lumbar support.
The majority of average weight side sleepers will most likely prefer the Casper mattress because of its Zoned Support system. They shouldn’t be experiencing too much pressure on their shoulders and hips. However, those who are closer to 230 lbs might feel too much pressure on both the Saatva and Casper.
Stomach sleeping, the majority of average weight people should feel better support when they are on the Saatva mattress. Stomach sleepers who are closer to 130 lbs should feel enough support from the Casper mattress as well.
Heavyweight Sleepers – Over 230 lbs
Larger back sleepers should feel better support when they are lying on the Saatva mattress. The two sets of coils should provide decent support while the base foam in the Casper might not be able to handle the heavier weight.
Side sleeping, larger people might not get enough pressure relief on either the Saatva or Casper. They might require a softer mattress with a thicker, more pressure-relieving comfort layer.
When they are stomach sleeping, larger people will feel better support on the Saatva. However, those who are 300 lbs or over are going to undoubtedly require a firmer, more supportive mattress. See our best mattresses for heavy people for more supportive options.
Lightweight Sleepers – Under 130 lbs
Lightweight sleepers should find the Saatva and Casper to be a good fit for all three sleeping positions. It really depends on what feel they are looking for – if they want to sleep “on top” of the mattress, they should choose the Saatva and, if they want to sink in a bit more, they should choose the Casper.
The Casper is also one of our best mattresses for lightweight sleepers.
Mattress Construction Differences
We will now take a look inside the Saatva and Casper mattresses and see exactly what they are made of. We will discuss each layer one by one and discuss how it affects the overall feel and performance of the mattress.
Cover
The Saatva features an organic cotton cover that is extremely soft and breathable. The Casper features a knit cover that is also thin and quite breathable.
Comfort Layers
Saatva’s cover is quilted with soft foam to give the top of the mattress a pillow top look and feel. The Luxury Firm model is plush, but the Plush Soft will be even plusher and offer more of a pillow top. Below that, there is a thin layer of memory foam that will help provide pressure relief and some extra lumbar support and contouring as well.
The top layer of the Casper contains soft, responsive polyfoam with AirScape technology. Basically, the foam is ventilated to promote airflow through the top of the mattress so that sleepers don’t overheat at night. Below that, there is a layer of Zoned Support – this is a layer of memory foam that is firmer toward the center and softer toward the head and foot of the mattress. This will make the mattress feel more supportive when people are back sleeping and stomach sleeping and softer when they are side sleeping.
Support Layers
The Saatva mattress features two sets of coils in its support layer. First, there is a set of microcoils that will provide a mix of support and contouring as well. Then, there is a set of high-grade coils that will provide excellent support, even for larger sleepers. The coils also contain LumbarZone technology which makes them firmer toward the center and softer toward the head and foot of the mattress.
The Casper Original mattress features base foam in its support layer that is firmer than the top two layers. This will provide a decent amount of support for back sleepers and some stomach sleepers.
Mattress Height
The Saatva comes in two heights, 11.5″ and 14.5″ – we reviewed the 11.5″ model. The Casper Original mattress is 11″ thick, so it is just a bit thinner than the Saatva we reviewed.

Saatva And Casper Performance Differences
We put the Saatva and Casper mattresses through a number of tests with regard to cooling, motion transfer, and durability – let’s see how they performed!
Sleeping Hot Or Cold
The Saatva mattress should sleep cooler because of its two sets of coils; they will promote airflow through the mattress and keep it from trapping too much heat.
The Casper Original also comes in a hybrid model, and that should sleep cooler than the Casper Original all-foam mattress we reviewed.
Motion Transfer
When it comes to handling motion transfer, the Casper Original is the superior mattress. It has a thick layer of memory foam in the second layer that is absorbing more motion than the top layer of the Saatva. Those who need the best mattress for couples might want to consider the Casper Original over the Saatva.
Edge Support
While the Casper is better with motion isolation, the Saatva wins out when we are talking about edge support. With its two sets of coils, the Saatva offers better support when we are sitting and lying down near its edge. This allows us to sleep closer to the edge of the mattress without feeling like we are going to roll off.
Durability
Based on their construction, both mattresses appear to be durable and should last for at least seven to 10 years. Between the two, the Saatva might last longer, given that it features two sets of coils.
Off-gassing
The Saatva mattress actually comes with free White Glove Delivery, so it will not arrive in a cardboard box the way other online mattresses do. The Casper does come in a standard cardboard box, so after we unpacked it, there was some initial off-gassing. This is normal for a bed in a box mattress and, after we left the mattress in a well-ventilated room, the smell did dissipate after 48 hours.
Noise
Given that the Saatva mattress features coils, it is a little noisier when we move around, but we do not hear this with the all-foam Casper Original mattress. The Saatva is by no means noisy, but this might be more of an issue after many years of use.
Sex
When it comes to finding a mattress for sex, couples should be looking for something more responsive that makes it easy to move around. Based on this, the Saatva might be a better mattress for sex, but the Casper Original shouldn’t be a bad option either.
Warranty Info
The Saatva comes with a 365-night sleep trial and a lifetime warranty, and the Casper comes with a 100-night sleep trial and a 10-year warranty.

The Casper is more affordable than the Saatva mattress – a Queen size Casper costs about $200 less than the Saatva.
Which mattress sleeps cooler, the Saatva or the Casper?
