Cocoonbysealy The Chill Mattress Review

Product Description

In the mattress industry, Sealy is a well-known brand name. It was founded in 1881. Tempur-Pedic bought the company in 2012. As a result, Tempur Sealy International, one of the world’s biggest mattress manufacturers, was formed.

Cocoon is a Sealy sub-brand that offers a bed-in-a-box service that is delivered right to your door.

Cocoon has two mattress lines:

  • Cocoon Chill Memory Foam Mattress, a 10-inch all-foam model
  • Cocoon Chill Hybrid, a 12-inch hybrid model.

On a scale of one to ten, both have a medium-firm feel. Special cooling mechanisms are provided to help manage sleep temperatures.

This evaluation focuses on the essential characteristics, features, benefits, and drawbacks of the Cocoon Chill Memory Foam Mattress.

The Cocoon Chill Mattress is an all-foam mattress with a 6 out of 10 firmness rating (medium-firm). It is suitable for a variety of body shapes and sleeping positions because to its softness. The mattress is made up of three foam layers, each of which has a particular purpose in terms of support and shaping in order to provide a balanced performance. It also includes a cooling cover to keep you cool while you sleep. The Cocoon Chill is 10-inch thick.

A high-density polyfoam support core is solid, supportive, and long-lasting. A polyfoam transitional layer sits on top of the support core. It’s sturdy enough to prevent sleepers from sinking too far into the more rigid support layer. As it is responsive and quickly returns to its original shape, this layer improves overall mobility.

For pressure point relief and contouring, the memory foam comfort layer adapts to the body. It comprises of low-density memory foam, which retains less heat. Low-density foam, on the other hand, is frequently not as long-lasting.

One of the Cocoon Chill’s most notable features is its knit cover, which is loaded with phase change material to alter body temperature. This material is made to absorb and dissipate excess body heat, keeping the surface of your mattress cool throughout the night. It has a 100-day free trial and a 10-year limited warranty.

The foams used in the Cocoon Chill mattress have been confirmed by the CertiPUR-US program, a non-profit organization that conducts rigorous safety tests before awarding certifications.

The sizes available are Twin, Twin XL, Full, Queen, King, and California King.

  • Material: Cocoon Chill is an all-foam mattress featuring a Phase Change Material (PSM) cooling stretch-knit cover, a Perfect Fit memory foam layer, a responsive comfort foam layer that contours, and the necessary support layers composed of strong foam.
  • Sizes: Cocoon Chill is available in all regular sizes: Twin, Twin XL, Full, Queen, King, Cal King
  • Pricing: Depends on size & variety
  • Shipping & Delivery: Free
  • Trial & Return: 100-night trial, full refund, and pickup
  • Warranty: 10 years limited mattress warranty

Pros & Cons

Cocoon Chill has a lot to offer to sleepers. It is recommended for

  • Back and Stomach Sleepers
  • Those who prefer a memory foam bed yet are hot at night
  • Folks who need pressure relief
  • Couples and light sleepers who are quickly agitated by noise and motion transfer
  • Budget buyers

Plus, it’s not the best for

  • Heavier folks
  • Side Sleepers
  • People who like a soft mattress
  • Those who want edge support
  • Folks who like a durable mattress (It uses low-density foam which is less durable)


It’s difficult to say whether a mattress is firm or soft. All mattresses should be weight-bearing, promote proper spinal alignment, and provide a comfortable and restful night’s sleep. Personal tastes determine whether a mattress is fluffy and spongy (what mattress businesses label soft or plush) or less so (what brands call firm). Cocoon Chill is classed as medium-firm by the industry standard for defining firmness. On a scale of one to ten, it has a medium-firm feel. The Cocoon Chill has a slight memory foam feel to it, but not too much. People will sleep on top of the mattress and should avoid sinking too much. It provides a comfortable combination of sturdy support and close-conforming pressure alleviation for sleepers. Due to its medium-firmness, it is suitable for a wide range of body shapes and sleeping positions. The mattress is made up of three foam layers, each of which serves a different purpose to provide a balanced performance in terms of support and shaping. It also comes with a unique cover that is designed to keep you cool as you sleep.

A support core made of high-density polyfoam is stable, supportive, and long-lasting. On top of the support core is a polyfoam transitional layer. It’s firm enough to keep sleepers from sinking too far into the harder support layer. This layer also increases the general ease of movement because it is sensitive and rapidly returns to its previous shape.

The memory foam comfort layer contours to the body for pressure point alleviation and shaping. It retains less heat as it is low-density memory foam.

Material & Construction

The Cocoon Chill’s three foam layers are each created for a different function, resulting in a balanced performance that includes both support and contouring. A support core made of high-density polyfoam is stable, supportive, and long-lasting. On top of the support core is a polyfoam transitional layer. It’s firm enough to keep sleepers from sinking too far into the harder support layer. This layer also increases the general ease of movement because it is sensitive and rapidly returns to its previous shape.

The memory foam comfort layer contours to the body for pressure point alleviation and shaping. It retains less heat because it is a low-density memory foam. Low-density foam, on the other hand, is often less durable.

The Cocoon Chill’s knit cover, which is infused with phase change material to adjust body temperature, is one of its most remarkable characteristics. This material is designed to absorb and drain excess body heat, keeping the surface of your mattress cool all night. When compared to other memory foam mattresses, the Cocoon Chill sleeps cool thanks to the low-density memory foam layer.

  • Layer 1: The top layer is constructed of 2-inch high-quality Perfect Fit Memory Foam, which conforms to your body size, shape, and sleeping position to promote a restful night’s sleep. It relieves a lot of pressure.
  • Layer 2: Cushioning support is provided by the 2-inch Responsive Comfort Foam, which lessens motion transmission and prevents the “sinking” sensation. It’s a transition layer between the memory foam and the support layer that works as a buffer.
  • Layer 3: The 6-inch Essential Support Layer is made of a thicker, more durable polyfoam that is pretty sturdy and resilient. It always bounces back.

The Cocoon Chill mattress’ layers are encased in a stretch-knit cover infused with patented Phase Change Material (PCM), which keeps you cool as you sleep. It’s a tad more breathable and feels cool to the touch.

Sleepers who reposition themselves while sleeping will have an easier time doing so if they have the correct mattress. With the sinking in feature of memory foam and softer foam mattresses, it is more difficult for the sleeper to change positions. If your companion repositions themself frequently during the night, you won’t want to feel every toss and turn in Cocoon Chill. Cocoon Chill’s Perfect Fit memory foam adapts and responds to the curves of your individual shape for a soft and supportive feel. The high-density foam conforms to your body size, shape, and sleeping position. The polyfoam transition layer responds fast and returns to its former shape. This layer also makes it easier to move about.

Comfort, Back Support, Pressure Relief


When purchasing a mattress, it’s critical to consider if it provides good back support, spinal alignment, and pressure reduction. Maintaining adequate spinal alignment while sleeping is essential for healthy back support. This means the mattress should keep your spine in a position similar to how it is while you’re standing. Pain, discomfort, lack of circulation, repeated tossing, and other issues can occur when a mattress pushes back against your body with too much force in a concentrated region. In general, side sleepers should be most concerned with “pressure points,” as this is the position in which your body’s weight is dispersed over the smallest surface area.

The ability of a bed to relieve stress in the shoulders, hips, and lower back is referred to as pressure release. The capacity of a mattress to accomplish this is mostly determined by your weight, sleeping position, and body form. Another issue for heavy sleepers is whether the foam version is strong enough to support their weight without slumping all the way down to the bottom support layer.

Unfortunately, no mattress can provide spinal alignment and pressure relief to all sleepers in the same way. Sleepers of various weights, body types, and sleep postures will have variable spinal alignment and pressure reduction capabilities.

The memory foam comfort layer of the Cocoon Chill provides pressure relief that is close-conforming. The transitional layer and support core help to correct the spine, while the memory foam comfort layer compresses slightly beneath the hips and shoulders to ease pressure and redistribute body weight.

Side sleepers, who require greater contouring to accommodate the width of their hips and shoulders, are more likely to benefit from pressure-relieving mattresses. The support core and transitional layers of the Cocoon Chill, on the other hand, are firm and even enough to support stomach and back sleepers.

  • Back Sleepers: Back sleepers require greater support, especially around the hips, which can sink into softer beds and inhibit good spinal alignment. Cocoon Chill is a medium-firm mattress with three foam layers that is appropriate for back sleepers of ordinary weight. Back sleeping should be fairly pleasant for people who weigh between 130 and 230 pounds. The soft memory foam moulds the body pleasantly, but there is enough of support underneath.
  • Side sleepers: The Cocoon mattress is excessively firm for side sleepers. While lying in this sleeping position, people may begin to experience pain on pressure points.
  • Stomach sleepers: Getting optimal spinal alignment for stomach sleepers might be more difficult, since some mattresses cause the hips to sink too much. For “stomach sleepers,” stability and support are especially crucial to avoid back and hip pain. Because it doesn’t allow hips to dip too much, the Cocoon Chill is ideal for stomach sleepers. In this situation, sleepers should feel properly supported.
  • Heavy sleepers: People who are overweight put a lot of force and pressure on the bed. Because Cocoon Chill is medium-firm, heavyweights over 230 pounds should have no trouble sleeping on their backs. The top layer contours the body well, while the support layer keeps the body in place. For heavyweight side sleepers, it might not be the best option. People who weigh more than 230 pounds are more likely to push through the comfort layer and experience shoulder and hip discomfort.
    The Cocoon Chill mattress should be suitable for heavier stomach sleepers. Because the bed provides adequate hip support, the body should not become out of alignment while sleeping in this posture. Those who weigh more beyond 300 pounds, on the other hand, may find the Cocoon unsupportive.

Cooling & Temperature Control


Memory foam mattresses are known for their ability to retain heat. The memory foam layer produces a tight feeling and traps heat as the sleepers sink into it. The premium stretch-knit cover of Cocoon Chill is endowed with an unique “Phase Change Material” that absorbs and disperses heat for a cool, refreshing feel. The memory foam comfort layer is also lower-density, which means it doesn’t hug the body as tightly and allows more heat to escape.

Motion Isolation and Sharing a Bed


This category assesses how well a mattress protects other people in the bed from being disturbed when their spouse rolls over, adjusts, or changes positions. The Cocoon Chill Mattress is ideal for couples, light sleepers, and adults who have to share a bed with children or pets. It, like other all-foam types, inhibits vibration spread. The all-foam layers, particularly the memory foam, hug the body, preventing disturbances from spreading across the surface. It’s almost certain that tossing and turning on the Cocoon Chill Mattress will not wake up your mate.

Edge Support


Foam mattresses aren’t usually extremely supportive along the mattress’s very edge, which is significant if you want to sit on the edge of the bed or sleep on it. Couples should also consider edge support, as poor performance here restricts both sleeping and sexual engagement to the middle of the bed rather than the periphery. Getting in and out of bed might also cause a disturbance to your companion, as the bed may flex if you sit on the edge. With all-foam mattresses, this is a regular issue. Although the Cocoon Chill’s support core is made of high-density foam, the edge isn’t sufficiently reinforced to avoid sagging.

Recommendation based on sleeping style

We all need to sleep well, no matter what posture we sleep in, in order for our bodies to recover and replenish. During the day, we actually shrink by one to two inches. The lack of fluids causes the intervertebral discs to contract, which causes this condition. During the night, the fluid repairs the discs. In order for this to function, you must sleep in a comfortable position. What do we mean when we say we’re in a good position? There are three types of sleep positions: side, back, and stomach sleepers, as well as those who prefer a combination of these positions. All three people have distinct demands and so have different experiences when it comes to the comfort, support, and flexibility that a mattress should provide.

  • Side Sleepers: The vast majority of people sleep on their sides. The body can sink into the mattress, but the waist must be supported and the spine must be adjusted. This prevents neck and back aches in the morning. The support sections for the neck and pelvis should be flexible to relieve pressure on these places. Side sleepers like a mattress that provides both contouring relaxation and firm support. The Cocoon Chill excels at both of these tasks. The supporting polyfoam transition layer and core restrict sinkage, while the memory foam comfort layer adapts to a side sleeper’s body and spreads out their weight to relieve pressure points. The Cocoon Chill may be best suited for side sleepers who weigh over 130 pounds due to its medium-firm feel. Because they won’t sink in as far, side sleepers under 130 pounds may experience higher pressure building around their hips and shoulders.
  • Back Sleepers: If you like to sleep on your back, it’s also critical that your shoulders and hips sink far enough into the mattress to prevent unpleasant arches. Back sleepers, on the other hand, prefer to feel as though they’re “sleeping on” rather than “sleeping in” a mattress. For a back sleeper, sinking too much into a mattress can be uncomfortable, especially if their hips sink deeper into the mattress than the rest of their body, putting pressure on their lower back. Back sleepers like a mattress that gently cradles the hips while offering enough support to keep the spine aligned. A back sleeper’s hips should be able to sink in slightly thanks to the Cocoon Chill’s memory foam comfort layer. The polyfoam transition layer and core provide support for a good sleeping posture. The Cocoon Chill is ideal for back sleepers of all sizes, particularly those weighing 130 to 230 pounds. Back sleepers weighing less than 130 pounds may not get as much cradling as they’d want, while those weighing more than 230 pounds may endure hip sinkage.
  • Stomach Sleepers: A less flexible mattress with a good amount of firmness is most ideal for sleeping on your stomach. This keeps your stomach from sinking too far into your body, which would limit your movements and cause curvature. This causes shoulder issues as well as neck stress. In fact, stomach sleepers require additional support to keep their spine aligned and comfortable. A soft mattress might cause a stomach sleeper’s midsection to sink into the support core, putting tension on their lower back. A firmer mattress prevents this by providing consistent support. The Cocoon Chill is popular among stomach sleepers of all sizes. It provides enough support to keep you in a comfortable position all night. The memory foam comfort layer gives some softness to the surface, while the polyfoam transition layer and support core keep the mattress faithful to its medium-firm classification and help prevent the sleeper’s midsection from sinking in too deeply.
  • Combination Sleepers-Those who alternate between various positions: Are you one of those guys that sleep on their back, stomach, side, and back in a single night, exhausting the entire spectrum of positions? You’re not on your own. According to studies, the majority of people shift positions roughly 20 times per night. The best mattress for combo sleepers is responsive and effectively isolates motion. The flexible memory foam top layer of the Cocoon Chill does an excellent job of reducing motion transfer. Cocoon Chill mattresses are well-suited to most average-weight sleepers, who will feel well-supported in whichever position they choose. Moving from one posture to the next, however, takes more effort if you are heavier.

Trial & Return

Why do mattress manufacture’s offer free trial period for online purchase of mattresses?

Whether you purchase a mattress in a store or online, you make a long-term decision that could impact your sleep health. When you buy a mattress in a store after lying on a few mattresses, listening to sales pitches, and getting some great deals, you ignore how you and your partner's body will react to the mattress. Any new mattress has a break-in period (adjustment period), and your body needs time to adjust to a better feel. Lying on a mattress for a short time in a store setting does not provide insight. Buying a mattress online further compounds the fact that you never got to touch or feel the mattress before you purchase. That's why mattress manufacturers offer an extended trial period to try the mattress in a comfortable home setting without any pressure and then make the call whether to retain or return.

What is the duration of Cocoon By Sealy’s risk-free trial period?

Cocoon by Sealy offers a 100-night sleep trial period starting from the delivery date.

What does Cocoon By Sealy’s warranty covers in terms of defects?
