Purple and Casper are both on the leading-edge of the online mattress industry. Casper broke onto the scene in a big way and became a well-known brand with a strong track record. For its own part, Purple has made its name with a unique, proprietary, and patented material that is employed in the comfort layer of its mattress.
As mattresses that have a generally similar price point, deciding which one is the best for you can be a struggle. This can be especially hard when considering a mattress like the one from Purple, which has a very distinct type of comfort layer compared to the Casper and many other foam mattresses that are on the market.
Both Casper and Purple offer other mattress models (such as Casper’s Wave and Essential mattresses and the Purple Hybrid and Hybrid Premier mattresses), but this comparison focuses only on the flagship offerings from each company. We’ll review the nuts-and-bolts of these mattresses and compare the performance of each to help you make a decision about which will be best for you.
Purple vs. Casper Mattress – Which One Should You Buy
Making a final decision about which of these mattresses to buy is tricky. There are benefits and downsides to each, and it may be hard for you to know which one is right for you. The guidance below offers some quick tips that may help you make your choice.
Buy a Purple mattress if you:
1. Are ready to try an innovative mattress material.
If you’re the type of person who likes experimenting with new products and designs or if you’ve tried out other mattress types and want something new, the Purple mattress is a perfect fit. It’s unique comfort layer material provides a different feel that many people love.
2. You want a bouncier mattress.
The nature of the Purple Grid material in the top layer of the Purple mattress is to be more resilient, which gives the Purple a bouncier feel. If you like more bounce or worry about feeling stuck in your mattress, the Purple may be good fit for you.
3. Want to know detailed mattress specifications.
Purple shares the details about the density and composition of their mattress layers while Casper protects most of that information as proprietary. If it’s important to you to know the details, go with the Purple mattress.
Buy the Casper mattress if you:
1. Know you like the feel of an all-foam mattress.
If foam works for you, there’s no reason to experiment with a different material like the one that is used in the Purple.
2. You weigh over 230 pounds.
The Purple mattress only has 2” of thickness in the comfort layer, which may not be enough to support heavier people. If you weigh over 230 pounds, you may “bottom out” of the top layer of the Purple, and as a result, the Casper will offer better cushioning and support.
Mattress Construction Comparison
There are some pretty significant differences between the construction of the Purple and Casper mattresses, and this section will introduce you to the fundamentals of how each of these mattresses is built.
The Purple Mattress is 9.5” tall with 3 layers covered by a knit fabric cover. The top layer is 2” of the company’s specialty Purple Grid. This material is known as a Hyper-Elastic Polymer that is a large array of small squares. When pressure is applied, the squares compress, and then they quickly bounce back when weight is removed.
The second layer is 3.5” of polyfoam with a density of 1.8 PCF that is designed to help bolster the top layer. The base layer is 4” of support polyfoam with a density of 2 PCF.
The flagship Casper mattress is 9.5” tall with a polyester cover. Under the cover are four layers of foam. The top layer is 1.5” of a specialty open-cell polyfoam. This layer is designed to provide contouring while staying cool and not allowing the body to sink too deeply into the bed.
The second layer is 1.5” of memory foam, which enhances the amount of contouring and pressure point relief provided by the mattress. The third layer is 1.5” of transition polyfoam, and the bottom layer is 5” of a support polyfoam.
A key factor in any mattress purchase is finding a mattress that is going to be comfortable. After all, if your mattress doesn’t feel right, you’re going to have a hard time getting to sleep and staying asleep throughout the night.
When it comes to comfort, firmness is the name of the game. The degree to which a mattress is hard or soft is absolutely central to its feel. At the same time, this is completely subjective since what type of feel is most comfortable for you will be different from what is most comfortable for other people. There isn’t any one firmness level that works for everyone, so choosing the appropriate firmness level for you can help make sure that your bed will be a place of relaxation and rest.
A scale of 1-10 is used to describe mattress firmness, and on this scale, 1 is the softest a mattress can possibly be while 10 is the firmest. Very few mattresses are produced at the extreme ends of this scale, and the most common level of mattress firmness is medium-firm, falling between 5-7 on this typical firmness scale.
Both the Purple Mattress and Casper mattresses are considered medium firm. The Purple is around a 6 on the typical firmness scale, and the Casper is a 6-7. Most people find the Casper to be slightly firmer than the Purple, but overall, the feel is generally similar.
Both the Purple and the Casper mattresses strive to provide a sleep experience that balances comfort, support, and resilience. As a result, they have many characteristics that are similar, but because of the differences in the materials that are employed in these mattresses, there are also some noticeable differences.
Overheating during the night happens for two main reasons. First, if the body sinks too deeply into a mattress, then it’s impossible for air to move around the body to cool it down. Second, many foam materials themselves retain heat, increasing in temperature through the night. For many sleepers, this can be extremely disruptive and uncomfortable.
The Purple mattress is a great choice for people who prioritize sleeping cool. The Hyper-Elastic Polymer used in the top comfort layer does not retain heat the way that most foams do, and it is also very resilient, which helps to prevent the body feeling trapped or swallowed by the mattress. The Casper mattress also has features to help with temperature regulation, such as open-cell foam, and most customers do not find that it sleeps hot. But when it comes to sleeping cool, the Purple is a top choice.
Both the Purple and the Casper do an excellent job of motion isolation and limiting disruptions that come from movement of another person who is sharing the bed. The bounce from the Purple mattress makes it transfer slightly more movement, but this will not be noticeable by most sleepers.
Responsiveness refers to how well a mattress can tailor its support to different parts of the body. A more responsive mattress is better at giving modified levels of cushioning to the parts of the body based on how much those parts of the body need. This kind of responsiveness goes a long way in promoting healthy spinal alignment.
The Purple and Casper mattresses both provide a responsive sleeping surface, but the way that they do so is quite different. For the Casper, responsiveness is offered by the two topmost layers, which are made of a proprietary polyfoam and memory foam. These layers contour to the body without being overly plush. For the Purple mattress, the Purple Grid is built to compress proportionally to the weight that is applied to it. It has less of a contouring feel than the Casper but still gives tailored cushioning to encourage alignment of the back and neck.
One difference when it comes to responsiveness, though, is that the combined comfort layer in the Casper is an inch thicker than in the Purple mattress. This added thickness can help the mattress be more supportive for people who weigh over 230 pounds or people who have very sharp pressure points.
Resilience and Bounce
The Hyper-Elastic Polymer used in the comfort layer of the Purple mattress bounces back to its original shape very quickly, which makes the Purple a very resilient mattress. This makes it easier to move around on the top of the bed. The Casper also has some bounce, but it does not regain its shape nearly as quickly as the Purple. For customers who put a priority on having a springy feel for their mattress, the Purple is a better fit.
Both of these mattresses are at best average when it comes to edge support. Materials that compress — like foam and the Hyper-Elastic Polymer — are usually weakest at the edges. Because neither mattress has materials designed to reinforce the edges, people who often sit or sleep near the edge of their bed may find the support there to be lacking.
Off-gassing and Smell
After unboxing, you should expect there to be some smell from both the Casper and Purple mattresses. For either option, the smell should go away within a few hours to a few days in any well-ventilated room. It is also important to know that any smell is not harmful.

Prices, Sizes, and Value

The Purple mattress is slightly more expensive than the Casper, but both are in same general price range. Purple tends to offer a bit more in terms of coupons or discounts, but it is also normal for Casper to have promotions that keep pace with those offered by Purple.
