Casper Original vs. Leesa – Which One is the Best?

In recent years, the popularity of memory foam has grown rapidly, with consumers getting used to their soft, plush response and subsequent pressure relief. At the same time, a number of complains have also risen, with users reporting heat buildups, poor edge support and lack of responsiveness. In order to tackle these issues, manufacturers have turned towards modified memory foam types and/or incorporation of multiple layers.

The Casper Original vs. Leesa comparison is about two such products that feature modified viscoelastic layers in conjunction with special or proprietary foams. Both mattresses are all-foam products, with the prime goal of maximizing user comfort. Due to their modified design, the response they generate is different than that compared to a typical memory foam mattress, which has been explained in detail below.

Casper Original Breakdown

The Casper Original is an all-foam mattress available in one firmness option, i.e. medium-firm. It tackles the conventional problems associated with memory foam through a layer of special open-cell foam.

Construction

Cover

The cover is made of pure polyester, tightly spread over the mattress’ layers. It is soft upon touch and also breathable, keeping the surface cool to sleep on. Moreover, it is removable that allows easy washing in case it gets dirty/sweaty.

First Layer

1.5 inches of special open-cell foam forms the first layer of the mattress, which navigates the entire response generated by the mattress. As your body makes contact with the open-cell foam, it contours according to your posture – just like memory foam – but at a slower pace, along with a certain degree of responsiveness. The latter prevents feelings of uneasiness due to excessive sinkage while allowing you to move around the mattress or change positions effortlessly. This is something that can’t be expected from a layer of memory foam. Lastly, the open cell structure makes the layer breathable, transferring any hot air away from the surface.

Second Layer

The layer generates the typical plush response so many memory-foam-lovers long for. It embeds itself into the response generated by the open-cell foam layer, sinking according to the body’s posture. Usually, a viscoelastic foam is employed as the top-most layer, however, this has been avoided by Casper Original to tackle issues of poor heat retention and non-responsiveness. This placement order allows you to enjoy the soft response of memory foam while giving the mattress a slightly latex-like bounce. Furthermore, any heat buildups in this layer are isolated from the surface through the breathable layer of open-cell foam.

Third Layer

This is a buffer layer of the mattress made of transition foam that has a medium level of firmness, slowing down any sinkage while keeping the body cushioned from the hard polyfoam base. The transition foam used in this layer has a zoned design, meaning it provides greater support at high-pressure points such as the lower back, and lesser support at low-pressure points such as the shoulders. This helps keep the spine aligned, providing targeted pressure relief to each major part of the body.

Fourth Layer

The final layer of the mattress; it is made of 5.5 inches of high-density polyurethane foam and acts as the support core of the mattress. It stops any further sinkage, keeping the body’s posture aligned, while at the same time supporting the upper layers of the mattress.

Firmness and Feel

Comfort and Support

As stated earlier, the mattress is offered only in one firmness level: medium-firm. The manufacturer hasn’t made the ILD ratings of the mattress public to prevent imitation but has clearly stated that the product is fit for a variety of users. This is largely true as the uppermost open-cell foam layer brings much-needed responsiveness to the mattress, even though its prime response is similar to that of memory foam. This is followed by deep compressive support by the polyfoam base that prevents excessive sinkage from taking place. Conclusively, the mattress provides plush comfort as well as a certain degree of bounce that makes it suitable for individuals with varying weight profiles, as long as they aren’t extremely under/overweight.

Edge Support

When a consumer makes an investment, he/she expects to make the most out of it. However, with memory foam mattresses, the edges are of little use as they turn into slopes as soon as pressure is applied. This isn’t true for Casper Original thanks to the open-cell foam layer that gives it ample responsiveness to resist instant compression upon addition of load. In addition, the stiff polyurethane base also brings in stiff resistance and keeps the layers above in an upright position.

Cooling

As the memory foam layer is located below the open-cell foam, any heat buildups are far away from the body. If hot air does make its way to the surface, it is driven away by the airflow set up in the open cell structure of the first layer. Moreover, the polyester cover also holds breathability, keeping the surface as cool as possible. This makes the Casper Original a viable option for enjoying the comfort of a viscoelastic foam in hot and humid climates.

Motion Transfer

Motion reduction is a vital parameter against which a mattress is judged, especially by couples with varying sleeping schedules. While excessive sinkage and lack of responsiveness are effectively deal by the addition of open-cell foam, motion isolation is also tackled effectively as the response of the upper layers is largely contouring. The inner bounce of the initial layer has only a tiny effect, which would be hardly noticeable while you’re asleep.

Unique Features

Plush Comfort with characteristic bounce

The Casper Original is an all-foam mattress with the response being similar to that of a memory foam product; however, it also possesses slightly latex-like properties, which generates some bounce. Thus, the mattress lets your body enjoy the contouring response but prevents excessive sinkage from taking place, which is otherwise annoying and causes discomfort.
