Casper is a young company but quite popular in the mattress market. This is because of many things. As a simple judgment, Casper mattress is good for its price. It provides medium firmness and good support for side sleepers. If you are interested in foam mattress, seek for medium firmness and need an affordable mattress, keep reading my Casper mattress review for more details.

Casper mattress’s Materials


Casper mattress is made of 4 layers of foam that results in 9.5 inches in total thickness. The big differences comes in the thickness and density used for each layer. In addition, Casper has changed their design for mattress three times, the details below are the latest version:

Casper mattress layers

Casper mattress layers (top to bottom) – 1.5″ poly foam, 1.5″ memory foam, 1.5″ poly foam, 5.0″ base foam

Top layer – Casper uses a 1.5″ of responsive poly foam for making the top layer. This aims to provide the great cushion, and bounce for mattress. In addition, the top is also designed to be contoured to your body, resulting comfort for sleepers.

Second layer – a memory foam that comes with 1.5 inches and a density of 4.0 PCF (pounds per cubic foot) is used. This aims to achieve the pressure relief and support goals for the mattress.

Third layer – this layer is made of 1.5″ poly foam, but the density comes with 2.5 PCF. This acts as transitional layer.

Bottom layer – the foundational base is designed with support poly foam. In additional, this foam has density of 1.8 PCF and 5 inches in thickness.


The design for Casper mattress’s look is something as common a standard for many online mattresses. It is simple, yet nice enough. The top surface is 100% white but the sides is grey and studier. There are differences in the components used for making the fabric.

The top surface is made of 100% polyester, meanwhile, side panels are made of 51% polyester and 49% polypropylene. This different portions leads to different feels. The top surface is softer and thinner. Along with that, because the cover is fairly porous, it helps to add more breathable and cooling feel for the mattress.

Additionally, not all Casper mattress’s covers are assembled in USA, some are assembled in Mexico. Along with that, the materials used for making the cover is derived from Belgium and USA.

Firmness Feel, Support and Others

In terms of firmness level, Casper mattress is rated as 6 out of 10 on the firmness scale when compared to many its competitions. In addition, the poly foam and memory foam are chosen to combine together on purpose, which aims to provide unparalleled support without sacrifice in bounce. What’s more? The memory foam is placed right under the poly foam layer as the way to minimize heat retention – a common issue of memory foam.

Casper mattress firmness

Casper firmness – medium / medium firm, 6 out of 10, where 10 is the most firm

With this combination of two top layers, the mattress is able to provide medium firmness, great softness and good contour to body of side sleepers, back and even stomach sleepers, but this doesn’t provide supportive support enough for heavy sleepers. They makes mattress easily sunk very far down.

Along with that, sadly, the edge support of Casper mattress is not something too great. It is weaker a bit than many mattresses out there. Especially, you can easily see that when sitting on the edge. This isn’t beneficial to those who sleep close to the edge and not ideal for amorous activities as well. However, this issue is still something acceptable for me who doesn’t sit much on edge of the mattress for daily activities like watching TV or using smartphone.

Casper is an above average mattress that offers a medium firmness and good support for average weight sleepers. The response poly foam + memory foam combination creates a balance of contour, but could deliver better performance with a thicker comfort layer. At launch Casper stood alone as the best mattress online. However, over the last 2 years a number of new competitors have stood up to challenge Casper. While Casper is still a pretty good mattress, many competitors simply offer better performance at a lower price.
