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 nd 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. It is also sold on Amazon. 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.

Cocoon Classic Mattress Performance

Motion Isolation

Memory foam mattresses tend to offer superior motion isolation. Memory foam “traps” movement and keeps it from transferring across the bed to a sleeping partner. The Cocoon’s foam layers absorb and isolate motion very well.

Edge Support

One drawback of memory foam beds – and the Cocoon Classic in particular – is the lack of edge support. Because the bed does not have a reinforced perimeter, the edges tend to sag and slump. Premature sinking around the edge – particularly in places where you normally sit – is common.

Heat Retention

We mentioned earlier that memory foam traps motion. Unfortunately, it does the same thing with body heat. This can result in a hot mattress and an uncomfortable sleep. If you tend to sleep very hot, the Cocoon Classic – and foam mattresses in general – might not be a good fit for you.


When a foam mattresses is compressed and sealed in plastic, it retains an odor that is released when it is first removed from its packaging. This is referred to as “off-gassing.” You should expect this smell with the Cocoon Classic, but it will go away after a few days.


The Cocoon’s support comes from its thick support base and a combination of foam layers. The support base is made of a high-density polyfoam, which provides a good foundation. The memory foam layer also provides solid support, customized to each sleeper based on the amount of pressure applied. The foam layers work together to provide pressure point and pain relief.


The Cocoon’s memory foam layer conforms closely to a sleeper’s body. You can expect that familiar memory foam “hug” that envelopes your body. Customers report that the Soft firmness setting offers quite a bit more “sink,” while the Firm setting doesn’t conform quite as closely.


The Cocoon Classic hasn’t been available long enough to know exactly how it will perform long-term. But Sealy, the company that manufacturers the Cocoon, is a very well-established brand in the industry. This fact, along with quality materials and construction, suggest that the Cocoon will hold up well over an average mattress lifespan.


Some couples find that memory foam mattress restrict movement too much and therefore inhibit their sexual activity. This could be an issue with the Cocoon. If this is a concern, the Firm setting would be the better choice.
