Key Characteristics of Cocoon by Sealy
The Cocoon is an all-foam bed made by legacy mattress manufacturer Sealy that also manufactures Tempur-Pedic and Posturepedic products. Cocoon is Sealy’s online mattress brand that’s made in America, affordable, and delivered right to your doorstep.
The Cocoon comes in the Classic and the Chill version. The Chill features Sealy’s proprietary Phase Change Material (PCM). This innovative tech absorbs and dissipates your body heat, so the sleep surface stays cool to the touch all night long.
Sealy has been helping victims of Hurricane Harvey through their partnership with Good360 with donations of cash and mattresses. The bed manufacturer is committed to disaster recovery philanthropies and works with Good360 who coordinates with local relief agencies on the ground to meet needs. They’ve delivered millions of dollars of mattresses and donations to disaster victims.
Cocoon by Sealy uses only CertiPUR-US® certified foams. Certi-PUR is a not-for-profit that certifies foam producers only after intensive safety inspections. This certification guarantees Sealy foams do NOT contain ozone depleters, mercury, lead, heavy metals, formaldehyde, regulated phthalates, PBDE, TDCPP, and TCEP flame retardants, and ensures low VOC emissions to protect indoor air quality.
The Cocoon by Sealy Is Perfect For You If…
For those looking for a reasonably-priced mattress made by a quality bed maker, Cocoon by Sealy may be a top choice for you. The Cocoon comes in two firmness options, soft and firm. Most every person, no matter their sleep position, can find a fit from one of these two offerings.
Because they need additional cushion on pressure points, side sleepers will likely prefer the softer version while stomach sleepers need the firm option so their hips won’t sink in and throw the spine out of alignment. Back sleepers will also benefit from the firm model.
If you like the sensation of memory foam and want a comfortable, no frills mattress, Cocoon is a top choice. Also, if your budget is tight, the Cocoon Classic is an excellent choice. For hot sleepers, spend the extra $150 to get the phase-change cover, the Cocoon Chill, for a cool to the touch experience.
The Cocoon by Sealy Might Not Be Perfect For You If…
Cocoon by Sealy advises the maximum weight for this bed is 500 pounds total. For those that sleep with a partner, if you’re both moderate weight, this might be fine. However, even given the total weight allowance, if you weigh more than 250 pounds or have a high BMI, the Cocoon may not work for you.
All-foam beds are often not supportive enough for heavyweight sleepers and may sleep hotter than you want. If you don’t like the feel of memory foam, the Cocoon won’t be a top choice for you. Also, if you’re looking for a premium, luxury sleep experience, this may not be for you. It’s a comfortable but basic bed.
Cocoon by Sealy Mattress Construction
The Cocoon by Sealy, whether you choose soft or firm, has three layers and is 10” thick. The difference in the two models is customized materials choice. The Cocoon Firm has two foam layers while the Soft has three. The Cocoon Chill differs only in that the cover is of high-tech materials.
From bottom to top, here’s what you’ll find inside the Cocoon by Sealy:
Support Core - Polyfoam
The support core differs based on whether you choose the soft or firm option. Sealy uses high-density foam (but does not provide specifications of the materials). The firmer Cocoon has an 8” core of high-density polyfoam while the softer bed uses 6” of flexible support foam. Both are heavy, resilient foams.
Comfort Layer – Polyfoam and Memory Foam
The comfort layers of the Cocoon also differ by the firmness you choose. The softer bed has a dual comfort layer of 2” of transition polyfoam under 2” of memory foam. With the firmer bed, the comfort layer is 2” of memory foam. The total bed height for either option is 10” with all layers.
Cover – Classic
The cover of the Cocoon by Sealy classic option is stretch-knit of spun polyfibers. It’s breathable and soft to the touch and has a pleasant visual appeal.
Cocoon Chill Mattress Construction
Cover - Cocoon Chill
In the Cocoon Chill, the standard cover is replaced by the proprietary Phase Change Material designed to take your body’s heat and dissipate it, so you don’t sleep hot. The bed is cool to the touch, and this high-tech fabric is the same used in high-performance textiles designed for extreme hot and cold climates.
Support and Comfort Layers - Polyfoam and Memory Foam
If you choose the Cocoon Chill, you should know that the innards of the mattress are the same as the Cocoon Classic. The proprietary technology that makes the chill perform as promised is in the cover material.
Firmness, Comfort, and Support
Construction controls mattress firmness
Mattress firmness is a primary concern for most buyers, but what makes a mattress less or more firm? Beds have two functional parts: the support core and comfort layer(s). The support core is the lower level of the bed while the comfort layer(s) are on top.
Beds may also have a stabilizing layer at the bottom and a transition layer between the core and comfort layer(s). The support core makes a bed more or less firm and determines how well it supports your spine and keeps it aligned in a neutral position for optimal sleep.
The softness of a bed results from the construction and materials in the comfort layer(s). The richness of the comfort layer determines how well it relieves pressure on your shoulders and hips and how much you sink into the mattress and it contours and hugs your body.
The mattress industry rates firmness on a scale of 1 to 10. The very firmest beds are rated 10, and the softest are rated 1. Most people sleep best in the middle of the scale on medium to medium-firm beds. Beds at either extreme are not preferable to most. Heavier people need firmer beds and lighter weight people usually prefer softer beds.
Cocoon by Sealy’s firmness
Cocoon offers two firmness options: soft and firm. These fall on either side of the mid-point of the firmness scale. The Cocoon Soft rates around a 4-4.5 on the scale. The Cocoon Firm comes in around 7 on the scale. The two beds are distinctive and sleep quite differently from each other.
Because Sealy doesn’t provide specifications on its materials, rating the firmness is subjective. However, mattress selection is a matter of personal preference so how the bed feels to you is important. Since technical specs aren’t provided, verified customer reviews on performance should be informative.
Both the Cocoon Classic and the Cocoon Chill are available in soft or firm options.
How Does Cocoon by Sealy Sleep?
The Cocoon by Sealy performs as you’d expect from memory foam. The two version of the bed, soft and firm, sleep quite differently. The softer bed is a plush experience and best for side sleepers, but there’s not a lot of bounce in the softer version.
The primary difference between the two is what Sealy calls the feel of sleeping “on the bed” versus “in the bed.” With the softer model, you sink more deeply into the comfort layers for a contouring hug. Some people may not like this sensation and some really love it.
The firmer bed, however, gives the “on the bed” feel where you’re on top of the materials, not sinking in, but still getting some contour from the top memory foam layer. This is usually better for back and stomach sleepers, but the sensation you prefer is subjective and a matter of preference.
Memory foam, as a rule, sleeps hotter than innerspring, latex, or hybrid beds. The Cocoon Classic will be warmer to sleep on, and if you run hot at night or prefer a cooler bed, you may want to invest in the Cocoon Chill upgrade for an additional $150.
The Cocoon soft version does a better job minimizing motion transfer than the firm, but both perform well in this regard. Memory foam is a top choice for reducing movement energy. If you or your partner shift around a lot, this is a definite plus for the Cocoon.
Off-gassing is common with most bed-in-a-box models. The unboxing aroma is mild and dissipates within 48 hours. Some people choose to unbox in a spare room then move the mattress into their bedroom. Cocoon is CertiPUR certified, so the VOCs are low.
Foam, in general, is less durable than a premium material like latex. For the low cost of this mattress, you can’t expect a decade of durability. However, for buyers on a budget that need a bed to last for a few years, this can be a top choice for good sleep at a reasonable price.

The Cocoon by Sealy is a top choice for bed-buying on a budget. If you want a basic, no-frills bed that will perform well, this may be your choice. Since Sealy doesn’t publish the specs on the density of their foams, it’s difficult to compare Cocoon to similar mattress models by other manufacturers.
As a stand-alone consideration, the price is reasonable for the sleep you get so long as you’re not expecting a premium sleep experience like you would get with a latex bed that would cost double or triple the price. It’s well-reviewed by verified buyers and can be a top choice.
Shipping, Trial, Warranty, and Returns
If you choose the Cocoon by Sealy, here’s what to expect:
Shipping via UPS standard is free. If you want the Cocoon faster, you can upgrade to UPS next day, second day, or Saturday delivery. The upgraded cost for other shipping options varies.
Sealy offers a 100-night sleep trial on the Cocoon. You can request a refund in that period or try an exchange to the softer/firmer option. If you exchange and still aren’t pleased, you can return and refund.
Returns on the Cocoon are free with no questions asked. They arrange for mattress pick-up and donation to charity, then give you the full price of your purchase back.
The bed comes with a 10-year, full replacement limited warranty but only if you buy directly from Sealy. The warranty covers only workmanship and materials defects.
Verdict on the Cocoon by Sealy
With 150 years of Sealy expertise in the design, engineering, and testing of the Cocoon, it’s a well-made bed, particularly for the price. As a memory foam bed, there’s lots of contour, but you should think carefully when choosing between soft or firm since soft sleeps hotter unless you choose the Chill.
The Certi-PUR assurance on the safety of the foam is reassuring, as is the rigorous testing that Sealy put this bed through while designing it. For those shopping on a budget that want a comfortable, basic, reliable bed, Cocoon by Sealy rates well. It’s a reasonable price for a bed from a top manufacturer.
