Casper vs. Cocoon Chill Mattress Comparison: Which Is Best? Update 05/2024

Mattresses from both Casper and Cocoon Chill may be purchased online, directly from the manufacturer, at comparable prices.

Sealy is a well-known brand in the mattress industry and boasts a wide variety of mattress options. A hybrid and an all-foam model are available in the Cocoon Chill line, both sold as a mattress in a box.

As a newer firm, Casper is gaining a lot of attention these days. The company was a pioneer in the internet mattress industry, and it served as an inspiration to many others. Casper’s hybrid and all-foam mattresses come in a variety of price points.

Many consumers are torn between Cocoon Chill and Casper beds since they both use memory foam and have similar basic features. Each model in the two collections will be compared so that you can see how they stack up against each other in terms of performance, price, and construction. Each company’s policy on shipping, refunds, and warranties will also be discussed so that you can make an informed decision when shopping for a mattress.

Cocoon vs. Casper Mattress Overview

It’s no secret that Casper was a forerunner in the bed-in-a-box mattress industry. Casper’s standard mattress is widely regarded as one of the greatest online mattresses, and the firm as a whole is valued at close to $1 billion, despite the fact that it has only been operational since 2014. Sealy, on the other hand, is a well-known and well-respected name in the mattress industry. It spent two years developing and testing over 100 prototypes before finding a winning formula for the shippable mattress competition.

Both Sealy’s Cocoon and Casper’s are among the most popular internet mattresses, yet their appeal is quite different. We’ll examine the firmness, look, and feel of Casper and Sealy mattresses, as well as their prices, in this comparison.

When comparing Casper vs Sealy, the following are the most important aspects to keep in mind:

  • It’s hard to tell the difference between Casper and Cocoon just by looking at them, but we can definitely tell the difference when we lay down on them.
  • Cocoon’s price has decreased both before and after the markdown.
  • Pressure relief and support are provided by a specific transitional layer in Casper.
  • Cocoon is the only company that offers a mattress with built-in active cooling for people who tend to get hot as they sleep.

Casper vs. Cocoon Construction

The flagship Casper Mattress is a three-layer, all-foam bed, as seen above in the breakdown of its manufacturing. It is slightly thicker than the Cocoon Chill mattress, which is around 11 inches thick.

  • The foundation of the bed is a normal layer of support foam.
  • To soften the harshness of the dense foam beneath, we add a layer of memory foam. Additional pressure alleviation and stability are provided by a zoned construction.
  • Unlike polyurethane foam, the third layer is comprised of the brand’s unique foam, which is neutral and responsive.

With a 10′′ thick mattress and a 3-layer design, Cocoon Chill differs from the other two mattresses. Cocoon Hybrid is a 12′′ mattress with a pocketed coil base layer, if you choose.

  • The first layer of your Cocoon mattress will be a thick layer of foam.
  • Just a touch of softness can be found in the middle of the mattress.
  • Memory foam is used in the mattress’s top layer, which provides the most comfort.

Sizing Options

The quality of your sleep is directly related to the quality of your mattress. Height, weight, budget, bedroom space, whether you sleep alone or with a spouse, and personal preference all play a role in determining size compatibility.

Mattresses are typically available in six basic sizes, but some manufacturers also offer customized sized options. The smaller dimensions of twin and full-size mattresses make them ideal for those who choose to sleep alone or with a child. Many couples and singles prefer the extra room provided by the queen and king sizes. A twin XL or California king, which are longer versions of the conventional twin and king, would be the better choice for someone who is taller.

When looking for a new bed, don’t forget to factor in the height and weight of the mattress. If you have joint or mobility concerns, you may find it easier to get in and off of a mattress that is thicker than most people prefer to sleep on.

The weight of your mattress has less of an effect on your sleep quality, although heavier versions can be more difficult to move.

If you’re looking for a mattress, Casper and Cocoon Chill both come in six common sizes: twin XL (twin), full (full), queen (queen), and king (king). There is a slight difference in the length of Casper mattresses and Cocoon Chill beds, but the size is equal.

Most of the Casper and Cocoon Chill mattresses are between 10 and 12 inches high, which is common for mattresses. These two mattresses are both 10 inches thick and made of all-foam materials. As the tallest of the two models, the Casper Wave Hybrid measures 13 inches.

Due to variances in building methods, there is a noticeable difference in weight between the two brands. Steel coil layers in hybrids make them heavier than foam-only ones. There are fewer layers and less complexity in the Casper Element’s all-foam construction, which makes it lightest.

Casper and Cocoon Chill mattresses are nearly identical in height and weight, making it unlikely that either metric will be a decisive factor.

Construction and Materials Comparison

The quality, durability, and comfort of a mattress are strongly influenced by the materials and construction methods used. There are many variables that affect a mattress’s performance, including responsiveness and motion isolation, temperature neutrality, and edge support.

Most mattresses are made up of different comfort and support systems, with transitional layers thrown in for good measure. Mattresses can have one or more top layers that are responsible for the overall feel of a mattress. The mattress’s support core is constructed of heavier materials that are designed to sustain the mattress and support the spine.

  • Casper and Cocoon Chill mattresses are either all-foam or hybrid designs.
  • This type of mattress often incorporates diverse materials like memory foam, polyfoam, or latex within the comfort layer. When it comes to hybrid models, it’s all about maximizing the advantages of various construction methods while limiting their negatives.
  • There are all-foam mattresses, which are made of foam. Memory foam, polyfoam, or similar materials are commonly used in the support cores, while the comfort systems are typically created from high-density foams for improved stability.


With three hybrid models and two all-foam options, the Casper mattress assortment is diverse. Depending on the model and kind of mattress, the construction and materials differ, but all mattresses offer a soft and stretchy breathable cover. Cotton, rayon, spandex and recycled polyester are used to make the cover, which is then sewn together.

The Airscape polyfoam, which is found in all Casper mattresses, is another notable feature. The foam has been engineered to promote ventilation, making it more breathable than ordinary foams. Airscape polyfoam in Casper mattresses achieves a good mix between body-contouring and responsiveness, which is why they perform well in pressure relief and mobility.

Materials and design procedures are unique to each model, therefore other performance ratings can vary widely.

Casper Original & Casper Hybrid

For optimal spinal alignment, the Casper Original is a zoned, all-foam mattress. Because of its perforated design, the polyfoam helps maintain a consistent temperature. There are three layers of foam in this mattress:

  • 1.5 inches of polyfoam Airscape
  • 7-inch polyfoam foundation with 2 inches of 3-zoned memory foam

The Casper Hybrid was created by combining the best aspects of the original Casper mattress with additional innovations. Polyfoam is used in the support core of both models, however the Casper Hybrid uses pocketed coils instead. Additionally, the coil core’s edges are reinforced. There are three layers to the Casper Hybrid mattress.

  • 1.5 inches of polyfoam Airscape
  • Memory foam in the form of a 3-zoned, ergonomically correct 2 inches
  • Pocketed coils with a 7-inch foam encasement are 6 inches in diameter.

Medium firmness is a rating of 5 on the 10-point scale for Casper mattresses, which includes the Original and Hybrid models of the mattress. For a wide range of body proportions and sleeping preferences, this level of firmness is ideal.

A similar contouring and pressure alleviation can be expected from the two variants. Targeted support is provided by zoned memory foam layers. The lumbar region and midsection are subjected to a lot of pressure, whereas the shoulders and neck are cushioned.

With a coil support core, the Casper Hybrid mattress is more responsive than the Casper Original. The Hybrid also includes a more robust foam encasement around the perimeter, which provides better edge support.

Casper Nova Hybrid

Compared to the Casper Hybrid, the Casper Nova Hybrid has a more complicated design. In total, there are four layers to the mattress:

  • Polyfoam with a thickness of one-inch
  • Airscape polyfoam with a 1.5-inch ergonomic, 3-zoned design
  • A two-inch thick layer of seven-zoned memory foam
  • Pocketed coils with a 7-inch foam encasement are 6 inches in diameter.

Compared to other hybrids, the Nova Hybrid has a more moderate (5) feel. The mattress has an additional layer of zoned memory foam designed to alleviate certain pressure points. The Nova Hybrid is also slightly more durable than the Casper Original and Hybrid.

Hybrid Casper Wave

With its specific materials and technologies for temperature management and support, the Casper Wave Hybrid mattress is a premium luxury model. The Wave Hybrid consists of five distinct layers.

  • Airscape polyfoam filled with cooling gel is 1 inch thick
  • Latex that is 1.5 inches thick.
  • a 1.5-inch layer of Airscape memory foam with three zones
  • Zoned polyfoam with targeted gel pods is 1.5 inches thick.
  • Pocketed coils with a 7-inch foam encasement are 6 inches in diameter.

The Wave Hybrid’s zoned polyfoam layer with targeted gel pods sets it apart from other Casper mattresses. The gel pods, which are dispersed throughout the polyfoam, are designed to conform to the body to aid with weight distribution.

If you prefer the sensation of memory foam but find yourself sweating at night, Casper has come up with an extra cooling technique for you. For an extra fee, the Casper Snow upgrades are available for the Nova Hybrid and Wave Hybrid. Phase change material in the cover and graphite HeatDelete bands are included in the cooling features. Together, these additional materials are designed to help diffuse heat throughout the mattress so that the sleep surface does not get uncomfortably hot.

Casper Element

The Element mattress from Casper is an all-foam design with two layers of foam:

  • a thickness of 3 inches of polyfoam from Airscape
  • Base polyfoam is 6.5 inches thick.

Even though the Element is the most streamlined model in the Casper line-up, the dual-layer foam model is made to conform to the body’s shape and promote proper spinal alignment.

Cocoon by Sealy

Sealy’s Cocoon Chill Memory Foam and Cocoon Chill Hybrid are part of the company’s Cocoon Chill Series. While one mattress is an all-foam type and the other is a hybrid, they both have the most popular firmness rating, medium firmness (6).

In keeping with the brand’s name, the Cocoon Chill Series is meant to maintain a constant temperature. Phase change material (PCM) is injected into the stretch-knit covers of both versions, which is designed to pull heat away from the body. Other characteristics are dependent on the methods and materials used in construction.

Cocoon Chill Memory Foam

Medium firmness, all-foam mattress with a stretch-knit cover infused with phase change material: Cocoon Chill Memory Foam

  • 2-inch thick layer of memory foam
  • 2-inch polyfoam transition layer
  • A six-inch layer of polyfoam

The Cocoon Chill Memory Foam Mattress has an average height for an all-foam mattress at 10 inches. Top memory foam gives substantial contouring and is cooler than denser layers of foam. The transitional polyfoam layer is relatively stiff and prevents sleepers from sinking too deeply into the main support structure. ‘ Changing postures is made simpler by the polyfoam’s springy quality. A high-density polyfoam base provides increased stability and support for the spine.

Cocoon Chill Hybrid

Due to the pocketed coil core, the Cocoon Chill Hybrid stands a little taller. Infused with phase change technology, the mattress’s stretch-knit cover is medium firm.

  • Perfect Fit memory foam, 1 inch thick
  • Perfect Fit transitional memory foam, a thickness of 2.25 inches
  • Polyfoam.75-inch thick over 8-inches of pocketed coils

There are layers of Perfect Fit memory foam that adapt to the shape of a person’s body to alleviate pressure points. Individually wrapped coils in the 8-inch support core reduce motion transfer and increase ventilation. The springiness of the coils makes it easier to move around, while the harder coils around the perimeter provide better support for the edges. Finally, the Cocoon Chill Hybrid’s foundation is lined with a.75-inch polyfoam layer, enhancing the mattress’ structural integrity.

Mattress Performance Ratings

You can’t get a mattress that’s perfect for everyone, and it’s even rarer for a single model to perform well in all areas. Mattress performance is influenced by a wide range of factors, including your own tastes and needs. Focusing on the aspects that are most important to you simplifies the mattress search.


Durability is an important consideration because most individuals do not want to replace their mattress on a regular basis. A long-lasting mattress prevents sagging and indentation from occurring early on. Quality materials and craftsmanship may extend the life of a mattress, even if wear and tear is inevitable.

Motion Isolation

Movement is less likely to spread across the bed if the mattress isolates motion properly. For couples and those who share a bed with a child or a pet, motion isolation is critical. Mattresses made of memory foam tend to be excellent in preventing disturbances from movement. When it comes to isolating motion, hybrid mattresses tend to be less successful than all-foam mattresses.


The sex appeal of a mattress is influenced by a variety of factors. The ability to react quickly, regulate one’s body temperature, maintain one’s edge, and move freely are all crucial. A lack of bounce might make certain poses difficult or impossible to perform whereas a better edge support increases surface area. When you have a heat-retentive mattress and you move a lot, it can be uncomfortable. Couples may also cherish the quietness of a mattress for their own space.

Temperature Neutrality

If you sleep hot, a mattress’ capacity to control temperature is critical to your comfort. Hybrids are better at keeping cool because the coils have a lot of room for airflow. Although many cooling technologies can be employed to improve the permeability of this material, standard memory foam has an undeserved bad reputation for retaining heat.

Pressure Relief

During sleep, pressure points such as the shoulders, hips, and back might become more aggravated, but a mattress with sufficient give can assist alleviate this problem. A mattress that is overly soft, on the other hand, might exacerbate back and joint discomfort associated with hunched over sleeping positions. A mattress’s contouring and support functions work together to provide the optimum pressure alleviation. The combination of a memory foam mattress with a supportive innerspring or high-density polyfoam foundation is a good illustration of this.


When purchasing a new mattress, it is common for it to produce a chemical-like odor. It’s known as off-gassing, and it occurs when volatile organic compounds (VOCs) in particular foam materials are exposed to the outside environment. Typically, the odor isn’t toxic and should diminish within a few hours to a day of the mattress being aired out.

Ease of Movement

Springy mattresses make it easy to get in and out of bed. With the help of an innerspring core, hybrid mattresses are usually good at facilitating movement. Memory foam, on the other hand, may be so molded to the body that it inhibits movement. To avoid the impression of being stuck in a mattress, many sleepers want a degree of responsiveness.

Edge Support

Adding a reinforced perimeter to a mattress improves the amount of usable space on the mattress. Couples, as well as those who sleep on their sides a lot, often appreciate a mattress with more edge support. It’s easier to get in and out of bed with solid borders for persons with back problems or mobility issues. Choosing a mattress with excellent edge support is best done with a hybrid or innerspring model.

One of the simplest and most economical hybrids from Casper is the Casper Hybrid. The Casper Nova Hybrid, which has four layers, outperforms the Original Hybrid in terms of longevity and functionality. The Wave Hybrid, Casper’s most expensive mattress, has five internal sections and features like targeted gel pods. The vehicle is nonetheless less expensive than other high-end hybrids.

Compared to other hybrids, this model is less expensive and shares a similar price tag with the Casper Hybrid. In terms of temperature neutrality and pressure relief, the Cocoon Chill Hybrid is on level with the Casper hybrids; however, it isn’t as long-lasting.

Trials, Warranty, and Delivery


If you’re going to buy a mattress online, it’s a good idea to check out the delivery rules before making a final decision. Free shipping to the continental United States is common, although deliveries to Alaska and Hawaii may be subject to additional charges.

A mattress in a box model like the Casper and Cocoon Chill beds is compressed in plastic and then placed into a box that can be easily delivered. Moving the boxes around is a breeze. The mattress grows to its normal size once the package is opened and the plastic wrap is removed. Because they can be purchased online and don’t need to be assembled by a professional, mattress in a box types have been increasingly popular over the past several years.

It’s impossible to tell if a mattress is right for you unless you’ve had a chance to sleep on it for some time. A sleep trial allows you to return the mattress if it doesn’t match your demands.

As a rule of thumb, a sleep study can last anywhere from 30 nights to 18 months. Before you may seek a refund, some firms want you to try the mattress out for a certain amount of time. The company often provides a free pick-up service. Customers may be asked to cover the cost of return shipping or to give their mattress to a local charity and submit a receipt in some situations. Always read the tiny print before making a purchase, as return policies can contain any number of exceptions or disclaimers.

Casper Sleep Trial and Return Policy

Companies have varying policies for assessing damage and handling repairs and replacements when it comes to warranties, which might be complete or partial. It’s possible that the corporation will pay for the return shipping costs, but it’s not always so clear-cut. The warranty may be voided if certain criteria are met.

Casper Mattress Warranty

Casper has the option of either repairing or replacing the mattress, depending on the degree of the problem. It is covered by the warranty for visible indentations of at least 1 inch, as well as splits or cracks that were not caused by misuse. The guarantee does not cover damage that occurs as a result of misuse or an inadequate foundation being utilized with the mattress. The cost of returning an item to us is not the responsibility of the buyer.
