In 2014, Casper mattress became one of the popular mattresses that are sold online. The mattress is advertised on televisions, Internet, and social media sites.  Similar to other mattresses in its category, it can only be purchased online. This frees you from the hassle of dealing with a middleman, thus enabling you to purchase a mattress without being stressed. In addition, this also gives you a lot of savings since the overhead costs are greatly reduced.

The goal of the producers of Casper mattress is to simply provide the highest level of support and comfort for all sleepers. Casper also gathers first-hand information from customers, consult with scientific experts, and perform focus group research for them to identify the real needs of people who are looking to purchase a mattress. They used actual results of their research to produce a mattress that suits the needs of all types of sleepers. Casper mattresses are made up of 4 layers of foam to give sleepers the support and comfort that they desire. This 4 layer-foam also contributes to the firmness and coolness of the mattress.

In this article, we will provide you a comprehensive review of this brand. We will determine if this product really keeps its promises. Here is a quick kasper mattress review.

Key characteristics

  • Kasper features 3 distinctive layers of foam (premium latex, high-density memory foam and standard foam).
  • Casper does not heat up as a result of latex foam on the top layer.
  • It includes free express shipping.

Mattress Layers

This mattress has a thickness of 9.5 inches. It is made up of 4 distinct layers of various types of high-quality foam. Because of this, it has the capacity to minimally retain heat, thus giving you that cooling effect. This also adjusts the contour of your body and provides a steady support. The 4 layers of this mattress are made up of the following:

  • 1.5-inch artificial Dunlop latex foam
  • 1.5-inch memory foam
  • 1.5-inch poly foam
  • 5-inch support foam

First Layer

The topmost layer of the Casper mattress is composed of 1.5-inch artificial Dunlop latex foam. This particular type of foam mainly contributes to the cooling feature of this mattress, since this does not retain heat and provides increase breathability, therefore making the mattress surface cool. Moreover, this foam has a density of 3.3lbs/cu.ft. This density is good enough to make the mattress “bounce”.

Second Layer

The next layer of the Casper mattress is composed of 1.5-inch memory foam. This foam allows the mattress to adjust to the contour of your body. The memory foam also provides support and is beneficial in relieving pressure. The most common downside of memory foam is heat retention. This is the reason why it is designated just below the artificial Dunlop latex foam. As mentioned earlier, artificial Dunlop latex foam keeps the surface of the mattress cool. The memory foam layer of this mattress has a density of 4.0lbs/cu.ft.

Third Layer

The composition of the third layer is 1.5-inch poly foam. This foam highly contributes to the comfort and support that the Casper mattress gives to the sleepers. The density of this poly foam is 2.5lbs/cu.ft.

Base Layer

The bottom part of the mattress is still poly foam that has a measurement of 5 inches. This foam functions as the foundation of the mattress. It firmly holds the above layers and it improves the comfort and support that the mattress provides. This base layer has a density of 1.8lbs./cu.ft.


Although technically, the cover is not considered a particular layer of the mattress, it highly contributes to the comfort the Casper mattress offers. The top part of the cover of this mattress is made up of 100% polyester, the side panels are composed of a combination of polypropylene and polypropylene, and the bottom part comprises a combination of aramid, polyester, and rayon.

The cover of this mattress is somewhat permeable; therefore, this enhances the mattress’ breathability and is beneficial in the reduction of heat retention. Breathability and minimal heat retention are some of the plus features of the mattress. On the other hand, the cover is weak and thin, which makes it susceptible to damage or tearing. Since this is the case, to prevent cover damage, ensure that you handle the mattress with care especially in transporting or moving it, or even during sheet changing.

How firm is a Casper mattress

Is Casper too firm? The short answer is No. The firmness is measured on a scale of 1 to 10, with 10 being the firmest. As for the Casper mattress firmness, we give it a score of 6.5. This mattress has only one available model, and this is intentionally designed to provide “universal comfort.” This means that this product is a one-size-fits-most mattress. Several sleepers have different opinions with regard its firmness. Some said that it is just right, others commented that it’s too soft, and a few expressed that it’s too hard.


The second layer of the mattress is made up of memory foam, which is an important factor when it comes to the comfort that this mattress provides. As commonly known, memory foam has the capacity to adjust to the weight and shape of the body, thus giving you comfort while you sleep. As mentioned earlier, it has a thickness of 1.5 inches, enough to give your body a comfortable hug. But, a few users have claimed that it hugs too much.

Pain Relief and Support

The memory foam (hybrid foam) is also beneficial in relieving pain caused by pressure. A lot of customers reported that their pain is significantly reduced when they sleep on this mattress as compared to the traditional one. Since this mattress is absolutely made up of foam, it provides sleepers a considerable amount of support. We discovered that the maximum foam indentation was minimal as compared to other mattresses. Therefore, the mattress provides sleepers sufficient support.

Heat Retention

Although the product is composed of a layer of memory foam, which obviously retains heat, this particular foam is situated under the latex foam, which is widely known to give a cooling effect. In addition, its cover is also made up of breathable materials. Therefore, the mattress is perfect for those who are looking for a mattress that has a cooling capability.

Off-Gassing – Does Casper mattress smell bad?

We are delighted to inform you that off-gassing in the mattress is minimal. Upon opening the package and unrolling the mattress, we have smelled a slight odor; however, it just disappears within an hour. If you are highly sensitive to odors and have observed undesirable smell, we recommend placing the mattress in a well-ventilated space for one to two days to reduce the odor.


Unlike innerspring mattresses, foam mattresses are commonly known to lessen the intimacy. This is so because foam does not have the capacity to bounce back easily. Therefore, when using the Casper mattress, you probably have to make a little extra effort when doing intimate acts.

Sleeping Position Ratings

Various sleep positions have different requirements when it comes to comfort and support. Because of this, it is our goal to discover the level of support and comfort the mattress has to provide for different sleeping positions. Please see below our findings:

Back Sleepers

For back sleepers, the mattress fits them well. The layered foams provide support for those who are used to sleep on their backs. This works by lessening the pressure placed on the shoulders, neck, and spine. We have also discovered that this provides enough comfort for back sleepers of all sizes and weights.

Stomach Sleepers

The same as side sleepers, small- and average-sized stomach sleepers will also love the mattress. It also gives them enough comfort and support. But, for those stomach sleepers who are extremely heavy may not like the mattress that much. This may not meet their needs in terms of support and comfort. The foam has the tendency to indent too much if the sleeper is very heavy.

Side Sleepers

We have found out that not all side sleepers are satisfied with the level support and comfort that the  mattress provides, especially those who are overweight. The foam tends to indent excessively if the sleeper is heavy.  It lowers the level of comfort and support, thereby resulting in body pain.

Bed Frame Compatibility

Ideally, the mattress requires a flat and firm foundation. One great foundation option for this mattress is the slatted base frame. It is best to use a frame that has narrow separations between the slats. A solid and firm platform foundation is also a good option. If you opt to use a metal frame, ensure that it is backed up with thick wooden slats that have proper and enough spacing to create a strong support for the bed.

Your chosen foundation for the mattress greatly affects the overall comfort that it provides; therefore, it is best to carefully and wisely choose your foundation so that you can get the maximum support and comfort that the Casper mattress offers.

Warranty, Guarantee and Trial Period

Warranty: The Casper mattress has a limited warranty of 10 years. A visible indentation of above 1 inch is covered in this warranty, except if the indentation is caused by an inappropriate foundation. The warranty also covers any damages caused by construction defects that lead to split or crack and damages caused by defective zipper system of the cover.

Guarantee:The company offers 100% satisfaction guarantee.

Trial Period: The company offers a comfort guarantee of 100 nights. If you think that the mattress does not meet your needs, the company will give you a full refund, as long as it is within the specified trial period. You will not be charged of any restocking fees and there are no hidden charges. Some company representatives will just pick up the mattress in your home. Then, it is either recycled according to local regulations or donated to a charity organization.


The Casper mattress can be classified as an above average mattress. It is made up of 4 layers of foam. For average weight sleepers, it provides fair support and medium firmness. It has a cooling feature, which is a great advantage. Moreover, it has a thick layer, which increases the level of comfort that the mattress provides.

Casper mattress is a great option for people who have an average weight and for back sleepers. But, if you are in search of a mattress that provides maximum softness and firmness, it may not meet your needs. In addition to that, if your weight is above average or if you are a side or stomach sleeper, this mattress may not provide you the support and comfort that you desire.
