The GhostBed Classic and the Casper mattress are leading all-foam mattresses that are sold online. These mattresses use carefully structured foam layers to provide a sleeping surface that can promote spinal alignment and provide a luxurious, welcoming feel for your bed.
The composition of these mattresses is different, and as a result, there are important differences in their characteristics and performance. By breaking down this information, while also reviewing the key logistical information (such as pricing, shipping, and return policies), you can home in on a mattress that is going to provide you with the absolute best sleeping experience.
As we begin this comparison, it is important to note that we are focusing only on the GhostBed Classic and the original Casper mattress. Though GhostBed also makes the GhostBed Luxe, and Casper makes its Wave and Essential mattresses, these mattresses are less well-known and are not the subject of this specific article.
Mattress Construction Comparison
A good place to start in evaluating and comparing mattresses is to consider how the mattress is built. The design and materials are a key determinant of the durability and performance of a mattress.
The GhostBed is 11” tall and on the exterior has a soft, stretch-knit cover. Inside, the mattress has 3 layers. The top layer is 1.5” of aerated, synthetic latex with a density of 3.5 PCF. This layer provides bounce and moderate contouring. Its aerated latex also helps avoid heat retention.
The second layer is 2” of gel-infused memory foam that has a density of 4 PCF. This high-density memory foam enhances the contouring effects by working in tandem with the latex layer. The base layer of the mattress is support polyfoam with a density of 2 PCF.
The flagship mattress from Casper clocks in at 9.5” tall and has a simple polyester cover. Inside, it has four layers of foam. The top layer is made of a specialty open-cell polyfoam that is 1.5” thick. The open-cell foam helps let heat dissipate, and this foam is built to offer some but not excessive contouring and sink.
The second layer is made with 1.5” of memory foam. This foam boosts the contouring effect and pressure point relief offered by the mattress. The third layer is 1.5” of a transition polyfoam, and the base layer is 5” of polyfoam. Specific technical specifications for these foams -- including the foam density -- are not published by Casper.
Comfort is a natural starting point for evaluating a mattress or comparing two different mattresses. The fact is that, regardless of all the other features or benefits a mattress has, you won’t be satisfied with a mattress unless you feel comfortable when you lie down on it to go to bed.
Comfort is determined primarily by the firmness level of the mattress. We measure firmness on a scale of 1-10. On this scale, a mattress with a rating of 1 is the plushest or softest that a mattress can be. A mattress with a rating of 10 is like concrete or as hard as a mattress can be.
Every person is different, which means that what level on this scale feels most comfortable to you may not be comfortable for someone else. We recommend thinking about your current mattress and trying to determine what level of firmness you want as this can then help guide your decision about your next mattress. If you’re not sure, medium firm (5-7) is the most commonly preferred firmness level.
The comfort feel of the Casper and GhostBed is very similar. Both fall as a 6-7 on the firmness scale. If you’re looking for a mattress that is clearly softer or harder than this, then neither of these mattresses is likely to be a good choice for you.
Like many all-foam mattresses, there are certain characteristics that the GhostBed Classic and the original Casper share. However, because of the differences in components, there are also areas where these mattresses diverge. In each of the following subsections, we’ll examine how these options perform in key criteria affecting the sleep experience.
Sleeping hot, or overheating in the night, can be a huge problem. For some people it can easily lead to fragmented sleep and daytime sleepiness. This overheating usually happens because of a lack of airflow around the body that happens when the mattress contours or hugs the body too tightly. In addition, some types of foam build up heat through the night, exacerbating heat retention problems.
The GhostBed and Casper mattresses each have elements of their design that helps counteract sleeping hot. The GhostBed uses latex, which does not have as much hug, and this latex is also aerated to reduce how much it retains heat. The Casper also uses an open-cell foam and one that, though it contours to the body, doesn’t permit as much sink as many traditional foam materials. As a result, both of these options are solid when it comes to staying cool through the night.
Motion transfer is the term that is used to describe how the movement of one person on a mattress can be felt by another person who is sharing the mattress. A goal of mattress design is to limit motion transfer, and the Casper in particular does a fantastic job at this. Its contouring level is sufficient to isolate most motion without causing someone to sink too deeply into the mattress. The GhostBed also does well at motion isolation, but because the latex in the topmost layer has more bounce, it tends to transfer modestly more motion than the Casper.
Responsiveness in a mattress is important for promoting spinal alignment and avoiding back problems. This is because responsiveness helps makes sure that the cushioning given to each part of the body is “just right” -- not too much or too little. For example, the shoulders usually need more support than the ankles and feet. If a mattress can’t provide proportional support, it may put too much pressure on the shoulder or cause the spine as a whole to become misaligned.
The Casper and GhostBed mattresses both use two layers of foam in their comfort layers, including a second layer of memory foam, in order to provide contouring responsiveness. As a result, each is effective at relieving the body’s main pressure points and supporting a healthy alignment of the body. Because it has a bit more contouring, the Casper may have a slight edge here, but the GhostBed still provides plenty of cushioning for sleepers in any position.
Resilience and Bounce
Some foam mattresses have more “bounce” than others. This bounce is a result of the resilience of the mattress, which means that the foam quickly pops back to its normal shape when weight is no longer being applied to it. This bounce can help make sure that you don’t feel stuck in one position on the mattress. Bounce can also help facilitate sex on a mattress and is important for people who place a high priority on a mattress that is good for intimacy.
High resilience is a characteristic of latex, and as a result, the GhostBed has a springier or bouncier feel than the Casper. However, the polyfoam in the Casper’s top layer is also built to have more resilience than traditional memory foam, so the difference in resilience between these two mattresses is not as pronounced as some might think.
There is no reinforcement of the edges in either of these two mattresses, which means that both are generally weak at this part of the mattress. If you sit on the edge of the bed, you are likely to feel the foam collapse quite a bit, and this is especially true if you weigh more than average. If edge support is a requirement for you, it may be necessary to look for a mattress other than the GhostBed or Casper.
Off-gassing and Smell
When first taken out of the box, it’s important to know that both of these mattress will give off a slight odor. This is normal for foam mattresses and it is not harmful. In just a few hours, this smell should dissipate completely as long as your room is well-ventilated.

The cost for the original Casper and the GhostBed Classic are similar, but the GhostBed is a more affordable option. Moreover, both companies offer discounts and coupons that can further reduce your out-of-pocket cost.
While price isn’t a clear differentiator, we can say that both of these are a solid value for well-designed all-foam mattresses. Neither is available at a bargain basement price, but given their track record and the quality of the materials used, the prices for both are reasonable.
GhostBed Mattress vs. Casper Mattress – Which One Should You Buy?
If you’ve pared your choices down to the GhostBed and the Casper, you’re well on your way to purchasing a quality mattress that is likely to deliver years of great sleep. But with so many considerations to take into account, making that final call on which to buy can be a quandry. In this section, we’ll list a few decision-points that might help simplify this choice for you.
Buy the GhostBed Classic mattress if you:
- Want a latex layer: latex is a popular mattress material because of its ability to be both responsive and bouncy. For people who adjust their sleeping position often or who want a mattress that’s best for sex, latex is a good choice, and because it’s in the GhostBed and not the Casper, it is a marked difference between these two choices.
- Want to know the technical specifications of your mattress: GhostBed publishes the density and other details of their foams, and Casper doesn’t. If you want to know this information before making a purchase, then go with the GhostBed.
- Weigh more than 230 pounds: sleepers who weigh more than average often do better with latex and with comfort layers that are greater than 3” in thickness. The GhostBed has latex and offers an extra half an inch of foam in the comfort layer, which can give some necessary extra cushioning to some sleepers.
Buy the Casper mattress if you:
- Prefer contouring over bounce: while the GhostBed has more bounce from latex, this also means that it sacrifices some of the contouring offered by the Casper. If you’d rather err on the side of more hug than bounce, the Casper is a better choice for you.
- Trust in the market leader: Casper has sold thousands and thousands of mattresses and is a market leader that can boast a nearly unparalleled list of positive customer reviews. This is no coincidence, and if you trust that Casper is a market leader for a reason, then it’s worth going with this option.
Both the GhostBed and Casper come with long sleep trials that allow you to test the mattress out without making any financial commitment. Because of this, you aren’t locked into any choice that you make.
While this offers some peace of mind, of course you want to try to pick the right mattress right off the bat. With the comparison in this guide, you can review your own priorities and needs and determine which of these solid choices is most likely to bring you years of sweet dreams.
