If anyone has done much mattress research, they have probably heard of Sealy, which is a company that has been producing quality mattresses since 1881.
Like many modern manufacturers, Sealy has gotten into the online mattress game with its popular Cocoon mattress. It’s interesting to test this mattress out and see if the quality that Sealy has become known for has translated into the Cocoon. This review will cover everything consumers should know about this mattress, including a full breakdown of the construction, the pros and cons, breathability, durability, motion isolation, edge support, comfort, support, and much more.
Who Might Want To Pick The Cocoon Mattress…
- Those who are looking for a value mattress- If someone is looking to save some money on a mattress, but they still want high-quality memory foam, the Cocoon should work well for them. It is an affordable mattress that is also very well made and an excellent overall value.
- Back sleepers- The Cocoon should offer great support and body contouring for back sleeping. At the same time, one’s hips should sink in just a bit while the memory foam contours well to the precise shape of the body.
- Stomach sleepers- If someone sleeps primarily on their stomach, they should feel well supported on the Cocoon. Their mattress should stay flat and supportive when they are stomach sleeping. If someone needs even more support, they can also opt for the Extra Firm model.
- People looking for a great firm mattress– Whether someone is looking for more support or just likes the feeling of a firm mattress, the Cocoon should be a good match for them.
Who Might Not Want To Pick The Cocoon…
- Side sleepers- If someone sleeps on their side, they will want to find a mattress that is soft enough to relieve pressure on their shoulders and hips. Even the Medium-Soft model will likely feel too firm when people are side sleeping, so side sleepers will most likely want to look for a softer mattress. Check out the best mattresses for side sleepers instead.
- Those who prefer a soft or medium-firm mattress- The Cocoon is a firmer-than-average mattress and might not be a good choice for those who like something softer. If someone likes a little more give in their mattress and wants some more comfort, they should look elsewhere.
- Someone who is a much larger person- While Marten found the Cocoon to be supportive, he is only 230 lb and not as large as others. If someone weighs more than this, this all-foam mattress might not be supportive enough for them, and they should definitely look for a mattress that incorporates coils in its construction.
- The Cocoon is 10” tall and features a simple construction with three foam layers.
- The cover is soft and contains a phase change material to make the mattress cool to the touch and a little bit more breathable
- The first layer is 2” of memory foam, which provides great pressure relief and body contouring.
- Then, there is a 2” transition layer that acts as a buffer between the memory foam and support layer.
- Finally, there 6” of a standard base polyfoam, which is a fairly standard base layer for an all-foam mattress available online.
- There are two firmness options with the Cocoon, and shoppers can opt for Extra Firm or Medium Soft. The Extra Firm version is going to be more supportive and better for heavier sleepers. As the name suggests, the Medium Soft version is going to be softer and feature softer comfort material, making it more ideal for side sleepers.
- Consumers also have another choice to make when they buy a Cocoon: Chill or Classic. The Chill model’s cover contains a phase change material that regulates temperature, which should ensure people don’t sleep too hot on the Cocoon.
- While the Medium Soft model has three layers, the Extra Firm model only has two layers. The Extra Firm model does not feature a transition layer, while the Medium Soft does.
- The top layer of memory foam has that classic, slow-moving feel, which means people should slowly sink into the top of the mattress. It will also provide a good amount of body contouring, which can be great for lower back support.
- Larger people might find this mattress to be quite firm because of its construction. The comfort layer is not very thick so if someone is larger, they could press right through it and hit the support layer beneath.
- The Cocoon’s materials are quite durable, so this should be a mattress that won’t sag.
How This Mattress Compares To The Tuft & Needle
If someone has been looking for an all-foam, bed-in-a-box mattress, they have probably come across the Tuft & Needle. Since these are both very popular mattresses, people might want to know how the Cocoon compares to the Tuft & Needle.
While these are both all-foam mattresses, they are different in many respects:
- In terms of design, the Cocoon has three foam layers, and the Tuft & Needle has a simpler construction with only two layers.
- Shoppers can choose from two firmnesses for the Cocoon and can also opt for the Chill version, while the Tuft & Needle only comes in one design.
- Both versions of the Cocoon are firmer and more supportive than the Tuft & Needle.
- Just speaking of price, the Cocoon does cost more than the Tuft & Needle, even when including available discounts.
- Their feels are quite different because of the differences in materials and construction. The Cocoon has a bit of that slow-moving memory foam feel on top. The Tuft & Needle lets people sink in quite a bit, but it is still a responsive mattress so sleepers shouldn’t feel stuck.
Side sleepers will most likely prefer the softer Tuft & Needle, while back sleepers and stomach sleepers will feel better support on the Cocoon.
Firmness And Feel
Speaking of firmness, I thought the Cocoon felt like a 7.5/10, definitely firmer than average. There is some soft memory foam on top, but that layer is only two inches. Pressing into the Cocoon, people will hit the support layer pretty quickly, so if someone is larger, they could feel like the mattress is even firmer.
Here is how it felt in different sleeping positions:
- Lying on my back, the Cocoon is a great match for me from a support perspective. My hips sink in just a bit, but the mattress supports me overall, and the top memory foam layer also conforms to the shape of my body.
- When I am side sleeping, the mattress is too firm for me overall. I am feeling some firmness when I lie down, and I am getting some pressure on the shoulders and hips.
- On my stomach, the Cocoon works very well, as the mattress doesn’t let my hips sink in. I feel very well supported on the Cocoon overall.
Again, while there is some memory foam on the top, it is only 2″ thick. So, people get some of that memory foam feel, but not too much. People will sleep on top of the mattress, and they shouldn’t sink in too much.
If someone sleepers with a partner, they should definitely keep motion transfer in mind. Basically, people want to find a mattress that isolates the motions made by them and their partner.
To test how well the Cocoon handles motion transfer, I put a glass of water on top of the mattress and pressed into other parts of the mattress, and the glass barely moved. I also laid down and asked Marten to get in and out of bed as well as roll around, and I can say that I barely felt his movements at all.
In the end, this lets me know that the Cocoon should be a good mattress for couples who don’t want to be disturbed by their partner’s movements. Make sure to check out our best mattresses for couples.
Couples and people who like to take up their whole mattress should also keep edge support in mind. People will want to know if they and their partner will get the right amount of space. Will they be able to sleep near the edge of their mattress, or will they feel like they are going to fall off?
When I sit near the edge of the Cocoon, the mattress doesn’t collapse too much. It is a firmer-than-average mattress, so that is not too surprising. Also, when I lie down, I can get very close to the edge while still feeling secure.
People can see the good edge support in the photo below.
If someone is looking for a new mattress, they should always consider their height and weight. I, for reference, am 5’9″ and weigh 160 lb. To give people a different perspective, I asked Marten, who is 6’7″ and weighs 230 lb, to try out the Cocoon. Let’s see what a larger person had to say about the Cocoon and how appropriate it is for heavier sleepers:
If someone is a larger person, they should definitely consider how comfortable and supportive their mattress is.
Specifically, if someone is a side sleeper, they want to think about how thick the comfort layer is. They want to make sure they aren’t bottoming out when they press through that comfort layer.
Since the comfort layer is only 2” thick on the Cocoon, I thought the mattress was firmer than Joe did, and it felt closer to an 8.5/10 for me.
Here is how it felt in different sleeping positions:
- Back sleeping, the Cocoon was a good match for me, as my hips sink into the comfort layer, but the support layer keeps them from sinking in too far. The top layer is also providing some nice contouring and lumbar support.
- When I move to my side, I press right through the comfort layer and feel some serious pressure on my shoulders and hips. It is not the best match for side sleeping as a result.
- Stomach sleeping, I am feeling good overall support, as I am not bowing in at the hips.
If someone is a heavier back sleeper, this could be a good match for them. Heavier side sleepers should look elsewhere, but heavier stomach sleepers should find this to be a good match.
Larger people like Marten should feel the support they need on their back and stomach. However, I think that if someone is a much larger than Marten (say over 300 lb), they might want to take a look at one of the best innerspring mattresses. They will want to make sure their mattress can handle extra weight.
Unboxing The Cocoon Mattress
When people receive their Cocoon mattress, it will be in a big cardboard box. First off, they should ask a friend to help them move the box into their bedroom.
Then, they can take the rolled up mattress out of the box and place it on their bed frame. Next, they can carefully cut through the few layers of plastic.
Since this is an all-foam mattress, people might need to give it a few days to fully expand.
What Makes The Cocoon Stand Out?
- There are two firmness options: Medium Soft and Extra Firm, maximizing the chances people will get the right firmness level for them.
- There is also a Chill model available if people worry about sleeping hot at night. It is one of the best mattresses for teenagers who sleep hot.
- The Cocoon is a supportive mattress that should be a good match for back and stomach sleepers.
- It’s one of the best value mattresses compared to other similar mattresses on the market.
- Even the Medium Soft model is a good choice for those who like firmer mattresses.
I enjoyed trying out the Cocoon mattress again. It is a supportive, all-foam mattress, and I like that there are firmness options.
The Cocoon comes with a 100-night sleep trial, 10-year warranty, and free shipping and returns. Financing is available. Sealy also offers many other mattress models.
