Which Mattress is Better? – Cocoon vs Casper

Quick Responsiveness: Casper
Contouring Comfort: Cocoon
Brand Reputation: Tie
Motion Transfer: Cocoon
Edge Support: Cocoon
Pressure Relief: Cocoon
Sleeping Cool: Casper
Value: Cocoon
OVERALL: Cocoon by Sealy!

Both of these beds are quality all-foam mattresses that pack a big punch when it comes to comfort. They both have their own qualities that make them unique, the Casper sleeps just a tad cooler (although we like the cooling Cocoon Chill cover) and it also has a more responsive feel than the Cocoon.

While the Cocoon does a great job at eliminating movement throughout the bed and has fabulous edge support for an all foam mattress. However, at the end of the day it is all of this combined with the price of the Cocoon mattress that really brings it home for us.

The Cocoon bed by Sealy is overall a more comfortable mattress that actually comes in at a truly great price, and that’s not even counting current discounts and our coupons. Which is why we choose Cocoon for our overall winner. Keep reading to get all of the details on materials and comfort to see why we believe it is the better buy.

Casper Mattress vs Cocoon – Delivery & Set Up:

cocoon mattress box deliveryCasper is one of the first brands people think of when you mention online bed-in-a-box mattress brands. Which is for good reason, they have paved the way with other front runners like Purple with loads of advertising and low prices. Sealy however is known for making great mattresses and is new to the online ordering mattress world. However, both have made these all foam mattresses that deliver to your door quickly and easily.

Whether you buy a Casper or a Cocoon mattress you can expect your bed to arrive at your home within a week or so. The unpacking process is rather similar overall, although we did find that the Casper had a bit more “new mattress smell” then the Cocoon mattress.

We believe this is due to the fact that Casper is assembled overseas while the Cocoon mattress is assembled in the USA. Casper and Cocoon both use all CertiPUR-US® certified as safe foams, so any smells that come out of either the Casper or the Cocoon mattress will be safe and should dissipate quickly.

We suggest leaving your new mattress to air out and firm up for at least several hours in a well-ventilated room before sleeping on it overnight. This will simply help to get a true feel for the mattress as well as to minimize the scent.

Casper vs Cocoon – Materials:

What a mattress is made of makes a big difference on how it performs, if you have an all foam bed it will behave differently than a hybrid mattress. Even two different all-foam beds like the Casper and Cocoon mattresses will feel different because they use different types of foam and other materials in order to create a different feel to their bed. Keep reading to get all of the details on what makes the Cocoon and Casper mattress unique.

What is Inside of the Casper Mattress?

casper mattress materialsCasper made their original mattress with a four-layer all-foam design. Starting with a base layer of dense support foam. This bottom layer of foam serves as the foundation for the rest of the mattress. Next up is one of the coolest layers in the Casper mattress, their zoned transition foam layer. This layer of foam is made up of different foam densities in order to provide more support where you need it most, along with more pressure relief that it is needed as well. This creates a mattress that gives you more of what you need right where you need it.

Next up is a layer of high-density memory foam. This gives Casper a good amount of cushioning without getting too warm, by having a cooler foam layer on top of the memory foam. This top layer of foam is an open-cell foam. The open-cell texture is what brings more airflow into the top of the mattress which helps keep the sleeper nice and cool. The top layer of foam on the Casper mattress also acts more like a latex foam than a memory foam, by this we mean that it has a much more adaptive feel.

For all those who dislike that “sinking” feeling that some memory foam mattresses have, you will enjoy how quick the Casper response to your movements. To top off the Casper mattress they use a stretchy cover that is soft to the touch and breathable.

What is Inside of the Cocoon by Sealy Mattress?

Cocoon has the simpler design out of the two mattresses we are looking at today. It consists of three foam layers, a comfort top layer, transition layer, and a base layer of foam. When you have such a simple design, the quality of materials you choose to put into your mattress will completely change the overall feel of the bed. Thankfully Sealy is experienced in the mattress world and they made some great choices with the Cocoon Chill mattress.

Sealy begins with a base 6” layer of dense supportive foam. This layer provides loads of support from edge to edge of the Cocoon mattress. Next up is their 2” layer of transition foam, this is vital for deep pressure relief and preventing any “bottoming out” feeling. (Bottoming out is when you sink straight through a comfort layer in a mattress and feel the firm base layer below.) Which is why the transition layer is key to overall mattress comfort and support.

Finally, there is the top comfort layer of foam in the Cocoon mattress. They choose a memory foam for their top layer of foam. This memory foam really conforms to the contours of your body.

Cocoon Mattress vs Casper – Comfort:

mattress firmness scale

Cocoon Comfort

cocoon mattress and casper comfortOne benefit for buying a Cocoon mattress over the Casper, is that it comes in two different comfort options for you to choose from. Sealy offers a Medium-Soft comfort option along with an Extra-Firm version as well. When we slept on the Medium-Soft option (the more popular of the two comfort options) we found that it slept around a 5-5.5 on our firmness scale of 1 being soft and 10 being the most firm. While their Extra Firm was around an 8.5.

The Medium-Soft option is a much more versatile comfort option that will suite far more sleepers than the Extra-Firm comfort option will. We suggest the Medium-Soft option for average sized sleepers who enjoy sleeping on their back or side and want a medium firmness level with lots of pressure relief.

While the Extra-Firm option is going to be better suited for average to large sized sleepers who prefer sleeping on their back or stomach. Side sleepers, the Extra-Firm is going to be too firm for you. While the Medium-Soft option will be too soft for stomach sleepers.

Casper Comfort

casper mattress comfortWhile Casper only comes in one comfort option, it just so happens to land right in our favorite sweet spot for mattress firmness, Medium-Firm. This is the level that tends to work best for the vast majority of sleepers no matter what size or sleeping position preference. Casper hits at a 5.5-6 on our firmness scale. This gives the mattress a rather universal feel. It as also more of a responsive mattress than the Cocoon, which is great for anyone who likes to switch positions throughout the night.

If you want loads of pressure relief and prefer a softer feeling mattress, then the Cocoon Medium-Soft, however for most people the single comfort option works rather well.

Motion Transfer – Casper Mattress vs Cocoon:

casper vs cocoon

All-Foam mattresses are typically the best way to go when it comes to looking for a mattress that will limit the amount of movement that travels throughout the mattress. This is due to the fact that coil systems inside of hybrid mattresses very adapting durable comfort, however they also create movement through mattresses. All-foam beds like the Cocoon and Casper mattresses tend to due a much better job at eliminating motion transfer.

However, there is a clear winner between the two for this category. The Cocoon does a better job at eliminating movement throughout the bed. This is due to the dense memory foam used in the mattress. This really stops motion and vibration in its tracks. While the Casper mattress is good with motion transfer on the whole, you will notice a bit more movement throughout the bed as it does have a more adaptive feel throughout the top layer of the mattress. Which is why we give the Cocoon the win for Motion Transfer.

Sleeping Cool – Casper vs Cocoon:

casper corner comfort comparison

Having a temperature neutral sleeping environment is an important aspect of comfort. It is difficult to get a great nights sleep if you keep waking up all hot and sweaty. While we typically suggest getting a hybrid mattress if you are concerned about sleeping cool, these all foam mattresses have made a few changes to their design in order to stay as cool as possible.

When looking for a mattress that sleeps cool the thing we suggest looking for most is airflow. The more air going through a mattress, the more space there is for heat to escape the mattress.

Does the Casper Mattress Sleep Cool?

casper mattress is comfortable compared to the cocoonIt is the top layer closest to the body that Casper really focuses on for keeping their sleepers cool. They use an open cell foam that provides lots a free-flowing air right up where you are sleeping which allows for any built up heat to escape out of the mattress.

They also use a lightweight woven cover that is nice and breathable as well. Since you don’t sink too far into the Casper mattress, this also helps to keep you from warming up throughout the night.

Does the Cocoon Mattress Sleep Cool?

cocoon mattress edge support overall reviewThe Cocoon does make a few precautions in order to keep their sleepers at a neutral temperature, however we found that it did warm up more than the Casper mattress did. This is because of all of the conforming memory foam that hugs the buddy.

It simply holds onto that heat more. However, they do have a Chill mattress cover. This cover uses thermic phase changing technology in order to try and pull heat away from your body as you sleep. While we love this cover and do find it helpful, Casper still takes the win for Sleeping Cool.

Edge Support – Casper Mattress vs Cocoon:

casper vs cocoon

Typically edge support is not a category where all-foam mattresses really shine. Neither the Cocoon or the Casper have any border enhancements or coils systems to give their edges loads of support, especially when you are sitting on the side of the bed. However, which you are sleeping up to the edge of either the Casper or the Cocoon mattress you are going to have plenty of edge support as far as sleeping surface goes.

If you are really wanting as much edge support as possible out of these two mattresses, we would suggest looking at the firm comfort option for the Cocoon mattress. This really does give you more support with the firm option than the softer version and will provide more than enough edge support when it comes to sleeping surface.

Casper vs Cocoon – Overall: 

If you love the feel and comfort that an all-foam mattress can supply, then either the Cocoon or Casper mattress are going to do a great job. They are rather similar mattresses while they have slightly different strengths.

Overall, they both do a great job at providing the comfort of a foam mattress. If you prefer a cool, more adaptive feeling mattress, then you might want to take a closer look at the Casper mattress. While if you are search for a true memory foam feel with different comfort options, then the Cocoon is really a great buy.

Since the Casper and Cocoon mattress are both rather similar as far as quality and comfort, the final aspect that tips the scales for us is the price. Cocoon’s prices are lower and that’s not even including our coupons. If you want a well-priced all-foam bed, the Cocoon is a great choice.
