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

All-foam and innerspring mattresses have been a common sight for decades within the sleep industry. However, with the rise of internet-based marketplaces and heightened awareness within consumers, manufacturers have turned towards a multi-layered approach, allowing them to inhibit the negative characteristics of a particular material.

The Casper Original vs. Purple comparison discusses two such mattresses where layers of different foams have been used by the manufacturers, with the efforts being compounded in the form of high-end yet affordable products that have varying amounts of plush-conforming responses.

Casper Original Breakdown

CLICK FOR PRICE

While memory foam has revolutionized the sleep industry, it does possess certain weaknesses. Casper has aimed to neutralize these by incorporating a layer of special open-cell foam, specifically targeting the long-standing issue of heat retention.

Construction

Cover

Pure polyester has been used to make the mattress’ cover. Fitted tightly over Casper Original’s layers, the cover has a soft feel, is significantly breathable and can be removed for cleaning purposes if the need arises.

First Layer

Featuring a thickness of 1.5 inches, the top layer consists of open-cell foam, issuing a response similar to that of memory foam, i.e. contouring according to your body’s pressure profile. A major advantage of this foam is its inner push that prevents your body from sinking too quickly into the mattress. Furthermore, the open cell design means dissipation of heat can take place easily, something viscoelastic foams are poor at.

Second Layer

This layer is responsible for providing the bulk of comfort and consists of 1.5 inches of memory foam. It works in conjunction with the upper layer, generating an enveloping effect, relieving stress off the joints. Any heat that does build up within this layer is isolated from the surface through the breathable open-cell foam.

Third Layer

With a density of 2.5 lbs./cu.ft and thickness of 1.5 inches, this layer is composed of transition foam, acting as a smooth gateway between the softer upper layer and the firm layers below. The layer, therefore, generates both plush comfort and conformity, slowing down the pace at which your body sinks into the mattress.

The layer features special zoned design, meaning its firmness differs along its length, being softer at certain points, e.g. shoulders, and firmer at concentrated pressure points, e.g. lower back. This has been done to ensure targeted support to the body and ample relief for your spine so that it aligns properly.

Fourth Layer

This is the final layer of the mattress and acts as a support core for the entire structure. 5.5 inches of polyurethane foam of 1.8 lbs./cu.ft density has been used for the layer, providing unyielding support to your body. After initial sinkage occurs at the upper layers, the layer ensures that the body doesn’t progress too deep into the mattress, which may otherwise result in joint strain.

Firmness and Feel

Comfort and Support

Neither the mattress’ firmness level nor its ILD ratings have been made public by the manufacturer to prevent imitation from competitors. However, the overall response is sufficient for an average sleeper who doesn’t have unique desires. A balance of pressure relief and inner push is maintained by the mattress, with the upper layers providing plush comfort that transforms into conformity as the body adjusts. Deep compressive support is provided by the polyurethane foam base, which is necessary for proper spinal alignment.

It must be noted that the transition layer’s zoned design plays a major part in spinal alignment as it ascertains the level of plushness/conformity each body part gets.

Edge Support

Memory foam mattresses aren’t the best when it comes to providing edge support. But, since the Casper Original has a layer of stiff polyurethane foam at the base, it is more supportive than typical memory foam beds. Furthermore, the top-most layer possesses a certain degree of the push of its own that prevents the formation of a slope as soon as you move towards the edges.

Cooling

Thermal regulation is one of the biggest challenges associated with memory foam mattresses. Casper Original’s inclusion of the open-cell foam counters this quite well as any heat buildups are dissipated through its breathable inner design. The strategic placement of the memory foam also plays a key role here as your body doesn’t come directly in contact with the thermal accumulations.

In addition, the polyester cover does possess a certain level of breathability, aiding the open-cell foam’s thermal regulation capabilities.

Motion Transfer

Memory foams have a dead response in the face of irregular disturbances or movements. Since the uppermost layers have a primarily contouring effect, the mattress is able to dampen such episodes locally rather than transferring them sideways and alerting your partner. Surely, the open-cell foam does have an inner push of its own, slightly similar to that of latex, but this isn’t noticeable in the majority of cases.

A common complaint by memory foam users has been entrapment. The presence of the upper open-cell foam layer prevents this from happening, allowing you to change positions easily as you sleep.

Unique Features

Plush aided by Conformity

The Casper Original combines memory foam with a slightly bouncy open-cell foam that helps it in achieving a unique plush-conforming response. The mattress adapts according to the body’s pressure while at the same time issuing a conforming response so that you don’t feel trapped. This gives you the hug of a traditional memory foam mattress while the freedom to move around effortlessly.

Cool for a Plush product

The prime responsibility of the mattress is that of a slightly conforming viscoelastic mattress. As stated earlier, memory foam products are poor at thermal regulation, however, this doesn’t hold true for Casper Original. The open-cell upper layer isolates the body from any heat buildups in the memory foam layer, while at the same time dissipating thermal accumulations through its aerated design.

Dead Response to Disturbances

The upper layers of the mattress have a largely dead response to movements that you or your partner may make throughout the night. These are absorbed locally and thus, don’t affect either of you, resulting in a calmer and uninterrupted night’s sleep.

Targeted Support

Most mattresses follow a uniform ILD rating for each of the constituent layers, thus providing the same response to all body parts. However, the transition layer within the mattress has a zoned design with varying firmness according to the body’s pressure points. This provides optimum pressure relief and helps keep the spine aligned. Moreover, this makes the Casper Original suitable for a wide variety of sleepers with special weight profiles and sleep styles.

Less Expensive

The mattress is less expensive compared to the Purple, with the price going down further through the use of our coupon code. At an affordable rate, you get a product that has the cradling effect of a viscoelastic mattress, minus the over-enveloping and heat retention issues.

Purple Breakdown

CLICK FOR PRICE

The Purple aims to provide its customers with a product that features both plushness and conformity, similar to memory foam and latex rubber, respectively. The mattress incorporates a proprietary foam and special configuration to achieve this objective.

Construction

Cover

The mattress’ cover is made of a blend of three synthetic fabrics, i.e. lycra, viscose, and polyester. The cover is soft upon touch and has a minimal thickness so that thermal regulation wouldn’t suffer. It must be noted that the fabric Lycra holds moisture-absorbing properties, making the mattress a viable contender for hot sleepers.

First Layer

The first layer of the mattress comprises of 2 inches of “hyper-elastic polymer foam”, a proprietary foam that has an adaptive response to your body’s pressure points, while at the same time allowing freedom of movement through an inner push. The response is somewhat similar to the upper layer of Casper as the latter also features conformity that prevents sudden sinkage.

In addition to being a proprietary technology, the structure of the layer is also unique. The foam features a grid configuration with constituent cells holding air. This lets your body float over the mattress until a certain amount of force is applied that results in elastic conformity. The unique structure also means thermal regulation is maintained, and the surface is kept cool.

Second Layer

At a thickness of 3.25 inches and density of 1.8lbs/cu.ft, polyurethane foam forms this layer. The function is similar to the transition layer in purple, acting as a buffer between the relatively soft upper layer and the support core below. The density of the layer gives it medium firmness, which isn’t as soft as hyper-elastic foam but also not as stiff as the layer underneath.

Third Layer

The final layer of the mattress, it is composed of 2lbs/cu.ft polyurethane foam. The prime purpose is to hold the entire structure of the mattress and to provide the body with solid support as it rests into the mattress. The manufacturer has made use of high-density foam for this layer, prioritizing longevity and reliability over short-term cost-cutting.

Firmness and Feel

Comfort and Support

Just like Casper Original, the mattress is available in only firmness level, i.e. medium-firm. The Purple’s design caters the needs of a wide range of sleepers, adjusting according to their sleep profiles. The major source of comfort within the mattress is the hyper-elastic polymer foam that delivers the hug similar to that of memory foam products but at the same time a degree of conformity that keeps the body’s posture aligned. The response is supplemented by the stiff support cores underneath that ensure that excessive sinkage doesn’t take place, which otherwise would make it difficult to change position and cause a nuisance.

Edge Support

Even though the mattress features a proprietary foam, it still is an all-foam product. Nonetheless, it holds its structure when pressure is applied along the edges, in a similar fashion to that of Purple. Some compression is observed as pressure is applied to the air-filled cells, however, the high-density polyurethane layers inhibit this response and keep the structure upright.

Cooling

The Purple fares better than the Casper Original in terms of cooling thanks to the air packed grid of the hyper-elastic foam layer. This allows cross-ventilation of air, taking away any heat accumulations with it. Furthermore, the foam possesses a molecular structure that doesn’t trap heat, unlike memory foam, making thermal regulation as efficient as possible.

Motion Transfer

Even though the upper layers have a somewhat cradling response as you lay down on the mattress, there is a certain amount of springiness present. This may lead to a minute level of amplification of the disturbance either you or your partner make at night. You can expect better motion isolation from the Casper as the upper layer generates lesser bounce compared to the hyper-elastic polymer foam.

Unique Features

Plushness and Latex-like Bounciness

The Purple incorporates properties of both memory foam and latex rubber, generating a contouring response studded with bounciness. However, unlike memory foam it doesn’t retain heat, nor does it exert excessive push, striking an equilibrium between the two. For a reasonable price, albeit higher than the Purple, you get to enjoy the conformity of high valued latex mattresses.

Thermal Regulation

The comfort layer does an excellent job at dissipating heat. Its inherent design prevents it from accumulating any bodily heat, while the ventilating structure keeps the surface cool, making it a suitable product for hot sleepers.

Compatibility

The dynamically adaptive design of the uppermost layer means neither you nor your partner would have to adjust sleeping positions to suit the other. The mattress responds according to the individual’s pressure profile, irrespective of the loading on the other side. Furthermore, the medium-firm option is suitable for a range of users, unless of course, you are severely under/over-weight.

Durability

The mattress has two layers of high-density polyurethane foam, holding the entire structure while maintaining spinal alignment. The manufacturer has specifically used high-density materials as it prolongs the mattress’ lifespan and reduces the chances of permanent deformation.

Which One To Get?

Casper Original

Here are some reasons to consider Casper:

  • You want a cheaper mattress: Combined with our coupon code, you can get the Casper Original at an affordable price; a mattress that holds plush conformity, while at the same time conformity that lets you change positions with ease.
  • You don’t want to miss out on viscoelastic products: The mattress consists of various layers, each having its own unique characteristics, but by large the response generated is still one that contours according to your body’s pressure points. This response has in fact been supplemented by added conformity that downplays the weaknesses of viscoelastic foam, particularly over-envelopment and heat retention. Therefore, if you’re looking to enjoy the hug of a memory foam mattress but don’t want to get trapped in it while sleeping, the Casper is a good choice.
  • You want greater motion isolation: The upper layers of the mattress generate a dead response to any irregular movements that may occur during your sleep, making it a viable choice for couples who don’t want to get disturbed by each other’s schedules.
  • You want targeted support: The transition layer within the Casper has a varying firmness level, stiffer below the back and softer over the shoulders. This results in optimum spinal alignment, regardless of the weight the person carries or the way he/she sleeps.

Purple

CLICK FOR PRICE

However, you might want to choose Purple if:

  • You want a viscoelastic response with greater bounciness: While the Casper does generate a degree of bounciness, it may still not be enough for some sleepers who desire greater conformity. For them, the Purple is a good choice as it has a contouring response of memory foam along with the bounciness of latex rubber.
  • You want greater cooling: The comfort layer of the mattress is composed of a proprietary foam that has a thermally neutral design, preventing heat from being absorbed. This is further aided by a cellular structure that promotes the flow of air, keeping the surface as cool as possible. Moreover, the Lycra used in the cover has moisture-wicking abilities, making the mattress suitable for humid climatic conditions.
  • You want to share your bed: the uppermost layers have a dynamic response according to the person resting on top of them. This means the mattress won’t automatically compress altogether depending on your weight profile, thereby, making it suitable for a lighter or heavier individual next to you! The mattress does have an extra degree of bounce to its response, but it is largely unnoticeable during sleep.
  • You want greater durability: The manufacturer has made use of high-density polyurethane foam that keeps all the layers well-aligned and prolongs the available lifespan of the mattress. This is backed by a 10-year warranty, giving you ample time to make the most out of your investment.
