If you’ve done much mattress research, you have probably heard of Sealy. It may be hard to believe, but the company has been producing quality mattresses since 1881!
Like many modern manufacturers, Sealy has gotten into the online mattress game. One of its most popular bed-in-a-box mattresses is the Cocoon. It is an all-foam mattress with two firmness options. Also, they offer a Chill version for you hot sleepers out there.
I reviewed the Medium-Soft Chill model before, and I was very excited to try it out again. Is this the all-foam mattress you have been waiting for?
You Might Want To Pick The Cocoon If …
- You are looking for a value mattress. If you are looking to save some money on a mattress, but you still want high-quality memory foam, the Cocoon should work for you. It is an affordable mattress that is also very well made.
- You are a back sleeper. The Cocoon should offer great support for back sleeping. At the same time, your hips should sink in just a bit while the memory foam contours to the shape of your body.
- You are a stomach sleeper. If you sleep primarily on your stomach, you should feel well supported on the Cocoon. Your mattress should stay flat and supportive when you are stomach sleeping. If you need even more support, you can opt for the Extra Firm model.
- You prefer a firmer-than-average mattress. Whether you are looking for more support or just like the feeling of a firm mattress, the Cocoon should be a good match.
You Might Not Want To Pick The Cocoon If …
- You are a side sleeper. If you sleep on your side, you want to find a mattress that is soft enough to relieve pressure on your shoulders and hips. Even the Medium-Soft model will likely feel too firm when you are side sleeping. Side sleepers will most likely want to look for a softer mattress.
- You 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 you like a little more give in your mattress and want some more comfort, I would look elsewhere.
- You are a much larger person. While Marten found the Cocoon to be supportive, he is only 230 lb. If you weigh more than this, this all-foam mattress might not be supportive enough for you. I recommend that larger people look for a mattress that incorporates coils in its construction.
- The Cocoon is 10” tall.
- The cover is soft and contains a phase change material.
- The first layer is 2” of memory foam.
- Then, there is a 2” transition layer.
- Finally, you have 6” of a standard base polyfoam.
- You have two firmness options with the Cocoon. You can opt for Extra Firm or Medium Soft. The Extra Firm version is going to be more supportive. As the name suggests, the Medium Soft version is going to be softer and feature softer comfort material.
- You have another choice to make when you buy a Cocoon: Chill or Classic. The Chill model’s cover contains a phase change material that regulates temperature. This should ensure you 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. This means you should slowly sink into the top of the mattress. It will also provide a good amount of contouring.
- Larger people might find this mattress to be quite firm. The comfort layer is not very thick so if you are larger, you could press right through it and hit the support layer beneath.
How Does This Compare To The Tuft & Needle?
If you have been looking for an all-foam, bed-in-a-box mattress, you have probably come across the Tuft & Needle. Since these are both very popular mattresses, you 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 two.
- You can choose from two firmnesses for the Cocoon and can also opt for the Chill version. The Tuft & Needle only comes in one design.
- Both versions of the Cocoon are firmer than the Tuft & Needle.
- Just speaking of price, the Cocoon does cost more than the Tuft & Needle.
- Their feels are quite different. The Cocoon has a bit of that slow-moving memory foam feel on top. At the same time, you sleep on top of the Cocoon. The Tuft & Needle lets you sink in quite a bit. However, it is still a responsive mattress so you shouldn’t feel stuck.
Side sleepers will most likely prefer the softer Tuft & Needle. 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. You do have some soft memory foam on top, but only two inches. Pressing into the Cocoon, you hit the support layer pretty quickly. If you are larger, you could feel like the mattress is even firmer than I did.
Here is how I feel in different sleeping positions:
- Lying on my back, the Cocoon is a great match for me. My hips sink in just a bit, but the mattress supports me overall. 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. I am feeling some firmness when I lie down, and I am getting some pressure on my shoulders and hips.
- On my stomach, the Cocoon works very well. The mattress doesn’t let my hips sink in. I feel very well supported on the Cocoon.
Again, while there is some memory foam on the top, it is only 2″. So, you get some of that memory foam feel, but not too much. You will sleep on top of the mattress, and you shouldn’t sink in too much. There is also almost no bounce.
Do you sleep with a partner? If so, you should definitely keep motion transfer in mind. Basically, you want to find a mattress that isolates the motions made by you and your partner. You don’t want to be waking each other!
To test how well the Cocoon handles motion transfer, I put a glass of water on top of the mattress. I 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. 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 choice for couples.
Couples and people who like to take up their whole mattress should also keep edge support in mind. You want to know if you and your partner will get the right amount of space. Will you be able to sleep near the edge of your mattress, or will you feel like you 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.
You can see the good edge support in the photo below.
If you are looking for a new mattress, you should always consider your height and weight. I am 5’9″ and weigh 160 lb. To give you a different perspective, I asked Marten to try out the Cocoon. He is 6’7″ and weighs 230 lb. Let’s see what a larger person had to say about the Cocoon:
If you are a larger person like me, you should definitely consider how comfortable and supportive your mattress is.
Specifically, if you are a side sleeper, you want to think about how thick the comfort layer is. You want to make sure you aren’t bottoming out when you 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. It felt closer to an 8.5/10 for me.
Here is how I felt in different sleeping positions:
- Back sleeping, the Cocoon was a good match for me. 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.
- Stomach sleeping, I am feeling good overall support. I am not bowing in at the hips.
If you are a heavier back sleeper, this could be a good match for you. Heavier side sleepers should look elsewhere. 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 you are much larger than Marten (say over 300 lb), you might want to find a mattress with coils. You want to make sure your mattress can handle extra weight.
Unboxing The Cocoon Mattress
When you receive your Cocoon mattress, it will be in a big cardboard box. First off, ask a friend to help you move the box into your bedroom.
Then, you can take the rolled up mattress out of the box and place it on your bed frame. Next, carefully cut through the few layers of plastic. Clear the plastic away, and you’re done!
Since this is an all-foam mattress, you might need to give it a few days to fully expand.
What Makes The Cocoon Stand Out?
- You have two firmness options: Medium Soft and Extra Firm.
- There is also a Chill model available if you worry about sleeping hot at night.
- The Cocoon is a supportive mattress that should be a good match for back and stomach sleepers.
- The mattress is a great value and is very affordable.
- 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 you have 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.
