Sealy is one of the oldest and largest mattress manufacturers in the United States. The Sealy Corporation was founded in 1881 when a cotton gin builder started making mattresses for his friends. When the cotton gin builder invented a machine that compressed cotton in 1889, he started licensing it to others. Soon, “mattresses from Sealy” became well known. In 2012, Tempur-Pedic International purchased Sealy.
Sealy mattresses are sold under three main brand names: Sealy Posturepedic, Stearns & Foster, and Bassett. This review will focus on the Cocoon by Sealy, which launched in 2016. Sealy offers two versions of the Cocoon: the Cocoon Chill and the Cocoon Classic. We will focus on the Cocoon Classic.
The Cocoon by Sealy has two firmness options: Medium Soft and Extra Firm. Both options feature a comfort layer of Perfect Fit Memory Foam. The support layer of the Medium Soft mattress uses Flexible Essential Support Foam, while the support layer of the Extra Firm mattress uses Reinforced Essential Support Foam.

The Cocoon Classic is available in two firmness settings: Cocoon Soft (4) and Cocoon Firm (6). This scale is from 1-10, with 10 being the most firm with 1 being the least firm. The Soft, which is the most popular option on this model, is noticeably more plush than typical mattresses. Sealy recommends this setting for those who like to be “hugged” by their bed. If you know you prefer that softer feel, it might be the best choice for you. The Firm is considered a medium-soft and is usually a safe place to start for most sleepers. Sealy recommends this settings for those who prefer a “more sturdy” feel for their bed.
The Cocoon Classic is available online at the Cocoon by Sealy website. Sealy does not sell the Cocoon through any brick and mortar retailers or at their own physical stores.
The Cocoon classic is a memory foam mattress, constructed in three layers. The two firmness settings have slightly different makeups. The Soft setting starts with a 6-inch support core of 1.8 PCF (pounds per cubic foot) polyfoam. That’s followed by a 2-inch transition layer of 2.2 PCF polyfoam, topped by 2 inches of 3 PCF memory foam. The Firm setting starts with 8 inches of 1.8 PCF polyfoam, topped with 2 inches of the 3 PCF memory foam. The mattress cover is a made of a stretch-knit polyester fabric.
As is typical with most “bed in a box” mattresses, the Cocoon Classic is manufactured, compressed, sealed in plastic, and shipped in a labeled box straight to your door. The bed arrives in one piece, completely assembled.
Shipping is free to any address in the United States, including Alaska and Hawaii.
The Cocoon Classic is delivered via UPS and typically arrives 5-7 business days after an order is placed. Next-day, two-day, and Saturday deliveries are available at checkout for an additional cost.
The Cocoon Classic should be removed from its packaging promptly after delivery, so it can begin decompressing. The mattress should be fully decompressed and ready to sleep on after just a few hours.
Sealy does not offer any additional delivery services at this time.
Sealy offers a 100-night sleep trial on the Cocoon Classic mattress, with no break-in period. If you are unsatisfied with your bed for any reason during the first 100 nights, Sealy will arrange to remove it free of charge and issue a full refund of your purchase price. Any delivery charges will not be refunded.
Sealy offers a 10-year warranty on the Cocoon Classic. Sealy will repair or replace any defective mattress during that time, but the owner will be responsible for any transportation charges related to the repair or replacement. Full warranty terms can be found here.
Cocoon Classic Mattress Performance
Like other all-foam mattresses, the Cocoon by Sealy isolates motion very well. The foam absorbs most motion, so you’re less likely to feel your partner tossing and turning during the night. However, the Medium Soft mattress will likely isolate motion better than the Extra Firm mattress since its 2-inch transition layer could help absorb motion.
Foam mattresses do not traditionally offer reinforced edges. Because of this, the foam compresses when you sit or sleep near the edge of the bed, which could create a feeling of instability. Like other foam mattresses, the Cocoon by Sealy lacks reinforced edges. This can make it difficult to sit or sleep near the perimeter of the bed and depending on your weight, reduce the sleepable surface area of the bed. While neither firmness option offers reinforced edges, the Extra Firm mattress should compress less than the Medium Soft mattress, so its edges may feel somewhat sturdier.
Since memory foam contours to the body, it can also trap heat against the body. As is common with foam mattresses, the Cocoon by Sealy may trap some heat. However, the breathable mattress cover should allow for cooling airflow to promote a cooler night’s sleep. Additionally, since the Extra Firm mattress does not provide as much contouring, it should sleep somewhat cooler than the Medium Soft mattress.
Foam mattresses usually emit a slight odor from manufacturing when you first unbox them. This odor isn’t harmful and should go away quickly, usually within the first week. To air out your mattress, just leave it in a well-ventilated space until the smell has dissipated.
With two firmness options, the Cocoon by Sealy should be able to provide good support and proper spinal alignment for a wide variety of sleepers.
Both the Medium Soft and Extra Firm mattresses use a 2-inch comfort layer of Perfect Fit Memory Foam that can contour to the body. Below that layer, each mattress has unique adaptations to provide support.
The Medium Soft has a 2 inches of transition foam and 6 inches of Flexible Essential Support Foam. This construction can allow sleepers under 130 pounds to sink in enough to promote proper spinal alignment.
The Extra Firm mattress uses 8 inches of Reinforced Essential Support Foam. This firmness can prevent sleepers over 230 pounds from sinking in too deeply.
As is common with memory foam mattresses, the Cocoon by Sealy offers very good contouring. The comfort layer of the mattress is composed of two inches of Perfect Fit Memory Foam that adapts to each sleeper’s size, shape, and position. This close conforming can relieve pressure points and provide added comfort. If you want even more conforming, you may prefer the Medium Soft mattress over the Extra Firm mattress.
A mattress’s overall durability depends on the construction and materials. Because of this, the Cocoon by Sealy should be durable. Information on the exact density of the foams used is not publically available. However, Sealy advertises high-quality, durable materials. Since the Cocoon by Sealy comes with a 10-year warranty, it can be expected to hold up well.
Since memory foam mattresses contour to your body shape, they can be more difficult to move around on. The same is true of the Cocoon by Sealy. The memory foam may retain the shape of your body, making it harder to change position. Additionally, the Cocoon by Sealy mattress lacks the bounce of traditional innerspring mattresses, so it may not be as ideal for sex as a springier bed. Since the Extra Firm mattress does not allow you to sink in as deeply, it may be somewhat better for sex than the Medium Soft mattress.

What Type of Sleeper Is Well Suited to a Cocoon by Sealy?
With every mattress review, we remind you that choosing the right bed is a personal decision. It’s important to consider your own personal preferences, sleeping position, body weight and type, and any health conditions you may be dealing with. Think about your own individual comfort and spinal support needs. We encourage you to make use of any sleep trial to ensure that the bed you chose is the right fit for you.
Side Sleepers: Between the two firmness options, the Cocoon by Sealy can accommodate most side sleepers across all weight groups. The 2-inch layer of Perfect Fit Memory Foam contours to the body and relieves pressure points. The Medium Soft mattress should allow side sleepers under 130 pounds to sink in deeply enough, while the Extra Firm mattress should prevent side sleepers over 230 pounds from sinking in too deeply.
Back Sleepers: Back sleepers usually benefit from a consistent sleep surface that conforms to the body without sagging. The memory foam layer in the Cocoon by Sealy provides desirable conforming, while the support foam can prevent sagging. Back sleepers over 230 pounds may benefit from the Extra Firm mattress. Back sleepers under 130 pounds may prefer the Medium soft mattress.
Stomach Sleepers: Since many people carry extra weight in their midsections, stomach sleepers generally need a mattress that will prevent their midsections from sinking in too deeply. The 2-inch layer of Perfect Fit Memory Foam in the Cocoon by Sealy is thick enough to provide contouring. However, it is also thin enough that it doesn’t allow excessive sink for most sleepers. Since the mattress comes in two softness options, the Cocoon by Sealy can accommodate stomach sleepers in different weight groups. The Medium Soft option is better for most stomach sleepers under 130 pounds, while the Extra Firm option is better for most sleepers over 230 pounds.
