Casper and Cocoon Chill both feature competitively priced all-foam and hybrid mattresses that can be purchased online, directly from the manufacturer.

Sealy has been well known in the industry for some time and offers an impressive number of mattress models. The company’s Cocoon Chill series includes one all-foam design and one hybrid, each sold as a mattress in a box.

Casper is a younger company that’s gained popularity in recent years. The brand was at the forefront of the online mattress movement and has inspired many bedding companies to follow suit. Casper offers a range of hybrid and all-foam models to match varying budgets.

Because Cocoon Chill and Casper mattresses both utilize memory foam and share core features, many shoppers find themselves torn between the two brands. We’ll compare both collections so you can see how each model rates in terms of performance, pricing, and construction. We’ll also give an overview of each company’s policy regarding shipping, returns, and warranties to help you choose a mattress with confidence.

Sizing Options

Getting the right size mattress is an important element of sleep comfort. Factors that drive size compatibility include height, body weight, budget, bedroom size, whether you sleep alone or with a partner, and personal preference.

Most mattresses come in six standard sizes, but some brands offer additional sizing options. Twin and full size mattresses are more compact and suitable for solo sleepers or children. Queen and king sizes are popular among couples and individuals who enjoy more space to spread out. A taller person might opt for a twin XL or California king, which are longer versions of the standard twin and king.

It’s also wise to consider mattress height and weight when shopping for a new bed. Some people prefer sleeping lower to the ground, but thicker mattresses are often more supportive and may be easier to get in and out of if joint or mobility issues are a factor.

Mattress weight has less of an impact on sleep satisfaction, but heavier models can make moving your bed more challenging.

All Casper and Cocoon Chill mattresses are available in the six standard sizes: twin, twin XL, full, queen, king, and California king. Casper models are also sold in a split king size for people who share adjustable beds.

Most of the Casper and both of the Cocoon Chill models fall within the standard mattress height range, between 10 and 14 inches. The Cocoon Chill is the shortest option between both brands, measuring 10 inches thick, while the 14-inch Casper Dream Max and Casper Snow Max offer the highest profiles of the two lines.

The variations in weight among both brands can be attributed to differences in construction methods. Hybrids generally weigh more than all-foam models since they utilize robust steel coil layers. With the fewest layers and least complicated design, the all-foam Casper One is the lightest mattress.

Differences in height and weight between Casper and Cocoon Chill mattresses are fairly negligible, so it’s unlikely that either attribute will be a deciding factor.

Construction and Materials Comparison

Materials and construction methods directly impact a mattress’ quality, longevity, and feel. Performance factors like responsiveness, motion isolation, temperature neutrality, and edge support all depend on how a mattress is crafted.

Most mattresses consist of separate comfort and support systems, sometimes with transitional layers in between. A comfort system may feature one or more top layers and is largely responsible for a mattress’ overall feel. The support core is made from more substantial materials, which are designed to support the spine and stabilize the overall mattress.

All Casper and Cocoon Chill models are either hybrid or all-foam designs:

  • Hybrid mattresses typically combine an innerspring support core with a comfort system made from various materials like memory foam, polyfoam, or latex. The philosophy behind a hybrid model is to emphasize the strengths of different construction methods while minimizing their drawbacks.
  • All-foam mattresses are made entirely from foam. The support cores are usually constructed out of high-density foams for greater stability, and the comfort systems use memory foam, polyfoam, or similar materials to contour to the body.

Casper

The Casper mattress collection features one all-foam model and four hybrids. Construction and materials vary based on the model and mattress type.

Casper One

The Casper One is an all-foam model designed to optimize spinal alignment. This mattress is considered medium firm (6) and contains three individual layers.

  • Adaptive polyfoam
  • Transitional memory foam
  • High-density base polyfoam

This budget-friendly mattress contours evenly to reduce pain and pressure buildup along the spine. It also excels at motion isolation for couples. The cover is a soft knit fabric blend.

Casper Dream Hybrid and Dream Max

The Casper Dream Hybrid has a four-layer construction:

  • Adaptive polyfoam
  • Zoned transitional memory foam
  • Pocketed coils
  • High-density base polyfoam

While the Dream Hybrid is considered medium (5) and conforms closely to your body, the zoned memory foam pushes back against the extra weight in your torso and hips. This helps maintain even alignment and a flat sleep surface. A knit fabric cover encases the mattress.

For an extra fee, you can upgrade to the Casper Dream Max. This model is similar to the standard Dream Hybrid, but mixes up the comfort system to include a top layer of adaptive polyfoam, a second layer of zoned polyfoam, and a third layer of transitional memory foam. The other components are identical to those of the Dream Hybrid, and the Dream Max is also medium (5) in terms of firmness.

Casper Snow Hybrid and Snow Max

The Casper Snow Hybrid is a medium (5) hybrid composed of five individual layers.

  • Memory foam with phase change material coating
  • “HeatDelete” bands
  • Zoned memory foam
  • Pocketed coils
  • High-density base polyfoam

The phase change coating on the first memory foam layer and proprietary HeatDelete bands are both engineered to dissipate body heat on contact. As with the Dream Hybrid, the Snow Hybrid’s zoned transitional memory foam layer provides extra support around your midsection and prevents you from sinking excessively. A cool-to-the-touch fabric cover encases the mattress.

You can upgrade to the Casper Snow Max, which adds a third memory foam to the comfort system. The Snow Max’s other components are identical to those of the standard Snow Hybrid.

Cocoon by Sealy

The Cocoon Chill Series by Sealy includes two versions: the Cocoon Chill Memory Foam and the Cocoon Chill Hybrid. While one mattress is all-foam and the other is a hybrid, both models sport the most widely preferred firmness level, medium firm (6).

As the name implies, the Cocoon Chill Series is designed to offer optimal temperature regulation. Both models feature a stretch-knit cover infused with phase change material (PCM) that is engineered to draw heat away from the body. Other features vary according to construction techniques and materials.

Cocoon Chill Memory Foam

The Cocoon Chill Memory Foam is a medium firm (6) all-foam mattress made with:

  • Stretch-knit cover infused with phase change material
  • 2-inch memory foam layer
  • 2-inch transitional polyfoam layer
  • 6-inch polyfoam base layer

Standing at 10 inches tall, the Cocoon Chill Memory Foam Mattress has an average profile for an all-foam model. The top memory foam layer offers substantial contouring and traps less heat than denser foams. The transitional polyfoam layer is moderately firm and prevents sleepers from sinking too deeply into the support core. The polyfoam also adds some bounce, making it easier to change positions. The sturdy base is made from high-density polyfoam for greater durability and spinal support.

Cocoon Chill Hybrid

The Cocoon Chill Hybrid is slightly taller due to the pocketed coil core. The mattress is medium firm (6) and is made with:

  • Stretch-knit cover infused with phase change material
  • 1 inch of Perfect Fit memory foam
  • 2.25 inches of Perfect Fit transitional memory foam
  • 8 inches of pocketed coils with .75 inch of polyfoam

The comfort and transitional layers are made from Perfect Fit memory foam, designed to mold to a person’s unique contours in order to relieve pressure buildup. The 8-inch support core utilizes individually wrapped coils to minimize motion transfer and promote airflow. The coils provide some springiness for easier movement, and firmer coils along the perimeter supply stronger edge support. Lastly, a .75-inch polyfoam layer lines the base of the Cocoon Chill Hybrid, increasing the mattress’ structural integrity.

Mattress Performance Ratings

There’s no such thing as a one-size-fits-all mattress, and it’s rare for a single model to excel in all performance areas. Among the many characteristics that determine mattress performance, your preferences and unique needs will determine which attributes you should prioritize. By focusing on the features that matter most to you, the mattress search becomes much easier.

Durability
Most people don’t want to regularly replace their mattress, which is why durability is an essential factor to consider. A durable mattress resists premature sagging and indentation. Although wear and tear is inevitable, quality materials and craftsmanship can greatly increase a mattress’ longevity.

Motion Isolation
If a mattress isolates motion well, then movement is less likely to ripple throughout the bed and disturb a sleeping partner. Motion isolation is an important aspect for couples and for those who share the bed with a child or a pet. Memory foam mattresses usually excel at preventing motion-related disturbances. Since hybrids offer extra bounce, they typically aren’t as effective at isolating motion when compared to all-foam designs.

Sex
A number of variables influence how well a mattress rates in terms of sex. Responsiveness, temperature regulation, edge support, and ease of movement are all key factors. Insufficient bounce can limit movement and make certain positions awkward or challenging, while better edge support increases surface area. Vigorous movement combined with a heat-retentive mattress may cause discomfort. Couples may also value the privacy of a mattress that doesn’t make too much noise.

Temperature Neutrality
A mattress’ ability to regulate temperature greatly influences comfort, especially if you tend to sleep hot. Hybrids are more effective at staying cool, since the coils offer plenty of room for ventilation. By contrast, traditional memory foam has a reputation for trapping heat, although various cooling technologies can be used to improve this material’s breathability.

Pressure Relief
Pressure tends to build up at the shoulders, hips, and back while sleeping, but a mattress with enough give can help cushion these sensitive areas. However, a mattress that is too soft may cause aches and pains associated with poor posture. For the best pressure relief, a mattress should strike the right balance between contouring and support. A good example is a close-conforming memory foam mattress paired with a supportive innerspring or high-density polyfoam base.

Off-gassing
New mattresses sometimes emit a chemical-like odor that can be off-putting. Termed off-gassing, the smell results when volatile organic compounds (VOCs) in certain foam materials are exposed to air. The odor isn’t usually considered harmful, and it should dissipate within a few hours to a day of the mattress being aired out.

Ease of Movement
It’s easier to move and shift positions on a springy mattress. Hybrids are usually good at facilitating movement, since their innerspring support cores provide bounce. This is in contrast to memory foam, which may conform so closely to the body that it impedes movement. Many sleepers appreciate some degree of responsiveness to prevent the feeling of becoming stuck in their mattress.

Edge Support
A mattress with a reinforced perimeter increases usable real estate on the bed. Couples often appreciate greater edge support, as do sleepers who tend to drift to the sides of a bed. Solid edges are also helpful for people with back pain or mobility issues since they make it easier to get in and out of bed. If you’re looking for a mattress with strong edge support, a hybrid or innerspring mattress is your best bet.

Pricing Information

Mattress pricing can vary dramatically, which may seem a bit perplexing at times. Cost depends on variables like mattress type, size, construction, thickness, quality of materials, and cooling features. Prices can also fluctuate based on manufacturing location, warranty and return policies, and shipping fees.

The average cost of a queen size mattress is between $1,200 and $2,000. With that said, some mattresses can run as low as $300 or upwards of $3,000. A better-quality mattress may cost more, but the odds are you won’t have to replace it as frequently.

Casper and Cocoon Chill mattresses are fairly comparable in terms of pricing. Their price-points are typical of mattresses of this type and quality.

Casper has a greater range of models and has more variation in pricing. The least expensive mattress of the collection is the Casper One, which has a very accessible price-point. The Dream Hybrid and Snow Hybrid are on par with the average hybrid model in terms of cost, while the Dream Max and Snow Max are luxury models with expensive sticker prices.

The Cocoon Chill Hybrid is less expensive than the average hybrid model and shares a similar price tag with the Casper Hybrid. While the Cocoon Chill Hybrid performs on par with the Casper hybrids in terms of temperature neutrality and pressure relief, it’s not quite as durable.

Shipping

It’s helpful to review shipping details before making a purchase, as policies vary when it comes to fees, turnaround times, professional setup, and mattress removal. Many companies offer free shipping to the contiguous U.S., while deliveries to Alaska or Hawaii may incur a fee.

The Casper and Cocoon Chill beds are mattress in a box models, meaning the mattress is compressed in plastic and then packaged inside a box for convenient delivery. The boxes are relatively easy to maneuver. Once you open the box and remove the plastic, the mattress expands to its normal size. Mattress in a box models have become increasingly popular in recent years as they can be purchased online and don’t generally require assistance to set up.

If you prefer, some companies also offer White Glove delivery, which means that a professional team will install the mattress in your home. The technicians will remove any packaging for you, and may also be able to remove your old mattress.

Casper Shipping Policies

All Casper mattresses ship free of charge to the contiguous U.S. Shipping is also available to Alaska, Hawaii, and Canada for an additional fee. Most mattresses are delivered within 5 to 7 days of order placement.

Casper offers optional White Glove delivery for an extra charge in select locations. After scheduling a delivery window, a technician will bring the mattress into your room of choice, unbox it, and discard the packaging. White Glove customers can also request removal of an old mattress.

Cocoon by Sealy Shipping Policies

Cocoon by Sealy offers free UPS Ground shipping for all mattress orders to the U.S. Orders are processed within 2 days and typically arrive within 5 to 7 business days. Expedited shipping is available for an extra fee.

Mattresses are compressed and shrink-wrapped for shipping. If you purchase the Sealy Ease Power Base, then your order is also eligible for free White Glove delivery.

Sleep Trial and Returns

Most bedding companies recognize that it takes some time for your body to adjust to a new bed, which is why many offer sleep trials with a mattress purchase. Even if you’ve done thorough research, you won’t know if a mattress is the right fit until you sleep on it for some time. If the mattress doesn’t meet your needs, then a sleep trial allows you to return it for a refund.

Sleep trials can be anywhere from 30 nights to 18 months, but the average length is 100 days. Some companies require that you test your mattress for a minimum period of time before requesting a return. A complimentary pick-up is often arranged by the company. In other cases, the consumer may be responsible for any return shipping fees, or the company may ask that the customer donate the mattress locally and provide a receipt. A return policy can have any number of exceptions or disclaimers, so it’s always a good idea to read the fine print before making a purchase.

Casper Sleep Trial and Return Policy

Casper offers a 100-night sleep trial for its mattresses. There isn’t a minimum break-in period, so returns can be initiated at any time during the 100-night window. Casper will issue a full refund and schedule a pick-up free of charge. White Glove service and other extra fees aren’t eligible for a refund.

Cocoon by Sealy Sleep Trial and Return Policy

Cocoon mattresses include a 100-night sleep trial, but Sealy recommends sleeping on the mattress for at least 30 days before making a decision. With that said, Sealy will provide a full refund for any return made during the 100-night period. Refunds are typically issued within 1 to 2 business days.

If you decide to return your Cocoon Chill mattress, then Sealy will arrange a pick-up at no charge to you. Depending on your location, Sealy will either recycle, donate, or discard your mattress.

Warranty

A mattress is a large investment, but a warranty can give you added peace of mind. Warranties cover possible defects in materials and craftsmanship. They do not cover damage associated with normal wear and tear.

Warranties may be either full or partial, and companies have different policies when it comes to assessing damages and handling repairs and replacements. Sometimes the customer is responsible for return shipping fees, while in other cases the company will cover the cost. Certain conditions may void the warranty.

Casper Mattress Warranty

All Casper mattresses have the same 10-year limited warranty, which is only valid for the original purchaser. Casper advises that customers retain their receipt or proof of purchase.

Depending on the nature of the defect, Casper will elect to either repair or replace the mattress. The warranty covers visible indentations of at least 1 inch , as well as splits or cracks not caused by improper use. Damage caused by abuse or by using the mattress with an insufficient foundation is not covered under the warranty. The customer is not responsible for return shipping costs.

Cocoon by Sealy Mattress Warranty

Cocoon by Sealy mattresses are backed by a 10-year limited warranty. This covers possible manufacturing defects, visible indentations deeper than 1 inch, and physical flaws, except if these are the product of improper use. Using the mattress without a proper foundation will void the warranty.

Sealy’s warranty is non-transferable, and the company will determine whether or not to repair or replace the mattress upon evaluation. Customers can also choose to upgrade to a better model by paying the difference.The customer is responsible for covering shipping costs.
