Casper VS Purple Mattress Features Comparison


Let’s start by looking at how these two mattresses are constructed.

This is an all-foam mattress that is available in 12-inches height. The brand targets medium firmness and a healthy bout of pressure relief and comfort. Therefore, you will only get one comfort level, which makes Casper be a great mattress for all types of sleepers.

The Casper mattresses have 4 layers, with the first one being the cover. The cover is made from a polyester combination, and it is pretty thin. However, the cover is still soft and comfortable.

The second layer is the comfort layer. The uppermost layer of the comfort layer is made of a latex-like polyfoam material. This layer has a bouncy feel and a fast response to pressure. Below the polyfoam layer is the memory foam layer.

The third layer is the transition layer. This layer is made of a firmer polyfoam with a zoned-support layer. This means that there will be softer foam close to your shoulders and firmer support close to your hips.

Last but not least, we’ve got the base or foundation layer. This is constructed with a firm HD polyfoam base. The key role of this layer is to provide strong support to the entire mattress.

The Purple mattress measures 9.5-inches in height and has a unique grid layer. This layer gives the user a unique feeling that other mattresses on the market can’t offer.

The Purple mattress comes with an exceptional cover that is made up of a mix of polyester, viscose, and lycra materials. The next layer is the comfort layer, which is constructed with Purple’s proprietary, hyperelastic polymer grid. This is a great layer as it responds excellent to pressure, and it is also bouncy. This layer is also neutral, and thus the air will flow through it naturally, and it won’t trap heat. One of the main differences between the Purple mattress and the Casper mattress is that Purple is constructed in a grid structure, while Casper is not.

The third layer is the transition layer. It is made of HD polyfoam, which provides extra support to the one provided by the base layer. And finally, the base layer is also made with HD polyfoam that is even firmer than the transition layer. This provides the mattress with the support that it needs.

When choosing your mattress, it is important that you select a comfortable mattress as you will be sleeping on it every night after a long and hectic day. So, if the mattress doesn’t feel right, you can be certain you won’t have a good night’s sleep, or you will have a hard time sleeping. For this reason, you need to find the right firmness.

The degree of firmness of a mattress determines its comfort and support. Some people find a soft mattress to be okay, while others prefer a medium-firm mattress. The level of firmness is tested using a scale of 1 to 10, with 1 being the least firm and 10 being the firmest. On the other hand, 5 is considered to be medium firm. When deciding on firmness, consider your weight and sleeping position. What is good for you may not be for another individual? Therefore, take your time and pick a mattress that you’re comfortable sleeping on.

Comparing the Casper and Purple mattresses, these two have been tested and found to have a medium-firm. The Purple mattress is considered to have a medium firmness of 6, while the Casper mattress is considered to have a medium firmness of 6 to 7. Generally, these two mattresses have a similar feel, and they are very comfortable for different sleeping positions.

Motion transfer

So Purple vs. Casper mattress: which one has better motion transferability? If you share a bed with your partner and they change the entire night causing you to have sleepless nights, then these two mattresses will be a great option for you. This is because they perform an outstanding task of motion isolation and reducing disruptions that emanate from the movement of another individual.

However, the Purple mattress has a bounce, which might slightly transfer movement, but this can go unnoticed by most sleepers. Unlike Purple mattress, Casper mattress absorbs and reduces motion to a great extent, making it slightly better than Purple in reducing disruptions from movement while sleeping.

Temperature control

Overheating at night can cause you to have sleepless nights. Normally, overheating is either caused by your body sinking too deeply into the mattress, making it almost impossible for the air to move around the body to cool it down, or by foam materials retaining heat. When foam materials retain heat, they increase the temperature throughout the whole night. To many individuals, this can be very disruptive and uncomfortable.

If you sleep hot and want a mattress that cools off perfectly, then you should go for the Purple mattress instead of Casper. This is because Purple mattress has a hyper-elastic polymer included in the top comfort layer. This layer doesn’t retain heat, and thus it helps prevent the body from feeling trapped by the mattress.

Even though the Casper mattress isn’t better than the Purple mattress when it comes to sleeping cool, it also has features of its own such as open-cell foam, which helps in regulating temperature. So, it’s still cool but not cooler than a Purple mattress.

Edge support

These two mattresses may be firm, but they don’t offer the best edge support. Materials like hyper-elastic polymer and foam are not very strong at the edges. So, since these two mattress materials don’t have reinforced edges, people who sit o the edge of these mattresses will find the much-needed support to be lacking. So if edge support is your priority, then you can check the other reviews of the best edge support mattresses, such as Naturepedic Mattress or Brentwood Home natural luxury mattresses.  The purple hybrid premier mattress also provides better edge support but costly than the original purple mattress.

Resilience and bounce

The Purple mattress comes with the hyper-elastic polymer in the comfort layer, which makes it bounce back quickly. Also, the Casper mattress has some bounce, but it doesn’t bounce back as quickly as the Purple mattress. The hyper-elastic polymer feature in the Purple mattress makes it bounce back rapidly and be a very resilient mattress. So, if you are an individual who wants a springy feel and a mattress that is easy to move around, then the Purple mattress will be an ideal choice for you.


When we talk about mattress responsiveness, we mean how well a mattress can provide its support to different parts of the body. A more responsive mattress is one that is great at offering modified levels of cushioning to the different parts of the body based on how much those parts require support. Such a response helps in promoting a healthy spinal alignment.

Both the Casper and Purple mattresses offer a responsive sleeping surface, even though they do it differently. The Purple mattress has a smart-comfort purple grid that is designed to compress proportionally to the weight that is applied to it. On the other hand, the Casper mattress comes with two top layers that are made of proprietary polyfoam and multiple layers of memory foam. These layers perfectly contour your body and respond very well. Hence, if you want a mattress that contours to your body well, then a Casper mattress takes the day over Purple.

Off-gassing and smell

Just like many other mattresses on the market, both the Casper mattress and Purple mattress will produce a smell when unpacked for the first time. But this shouldn’t worry you at all as the smell doesn’t last long. In addition, you should note that the smell is not harmful, and it will last for a few hours to some days before it completely disappears.


If you’re a couple looking for a nice mattress for a sound night’s sleep, then these two mattresses will be a good choice for you. The Casper mattress may be somehow bouncy, but it is not bouncier than Purple. Also, many previous users say that Purple is bouncy but not very bouncy. But between these two, the Purple mattress is slightly bouncier and the better option in this category.


This is one of those features that these two mattress models perform exceptionally. They are both very silent when bearing weight.


The Casper and Purple mattresses are in the same price range, but the Purple is slightly expensive. However, Purple tends to provide lots of discounts or coupons, which make it be slightly cheaper. But the Casper also provides promotions that keep pace with those offers given by Purple. With this kind of competition, you will find that these two brands offer almost the same prices for their different mattress models, from twin XL to the queen and California king beds. But if you select a wave Hybrid mattress model of these two brands, you have to spend some more.
