Casper Mattress Overview:

casper all foam original mattress comparison reviewIt is hard not to think of Casper when it comes to bed-in-a-box brands. This company paved a way for online mattress shopping. Giving everyone access to a bed that could be easily bought and shipped right to their door. Having an all foam, universally appealing feel and at the right price for many mattress shoppers. This took the concept of mattress shopping to a completely different level.

The original Casper mattress features 4 layers of foam carefully balanced to make a 12″ mattress that should work for just about anyone. Over the years there have been a few changes made to this bed. For an example, it used to be a 10″ mattress and has since been upgraded to 12″. Whether for better or worse, they still are one of the most popular brands and a name to reckon with.

Cocoon by Sealy Overview: 

cocoon by sealy mattress comparison reviewThe Cocoon Chill by Sealy is willing to take the challenge of one upping the O-G of online mattresses.

They offer a true memory foam mattress available in not only one, but two different comfort options. Giving sleepers an online option from a established, well known brand that is also giving them more choice.

This bed-in-a-box combines 2 layers of comfort foams with a base layer for 3 layers total. Together making a 10″ mattress available in a soft or firm feel. The true memory foam feel of this mattress hugs your body and cocoons you in comfort – giving this mattress its name. Backed by years of mattress industry experience from Sealy, this brand is surely one that will not disappoint.

Casper vs Cocoon – Off Gassing & Delivery:

casper delivery process compared to cocoonThere shouldn’t be much difference in this category for the Casper and Cocoon mattresses. Both are made in America, compressed, put into a compact box and shipped right to your door. However, the off gassing and fumes did differ when opening these mattresses.

While the Cocoon had minimal odors during the set-up process the Casper wasn’t quite as minimal.

Unfortunately, the Casper was quite strong with odor initially. And it even lingered for several days until it finally dissipated after several weeks. Making the Cocoon far more appealing, especially if you are sensitive to smells.

While Cocoon is much less smelly, the Classic Casper offers something to their customers that Cocoon does not.

Casper offers an home set up for free with the cost of purchase. Depending on your particular needs, this may be a big benefit that Sealy does not offer with Cocoon.

Casper vs Cocoon – Comfort:

When it comes to the comfort of any mattress there are a few ways to go about judging the comfort. First is the firmness level of each bed. Rating them on a scale between soft and firm and trying to find a feel that is compatible with most sleepers is key.

softness scale meterThe Casper comes in one universal feel that is considered a medium-firm feel. On a the firmness scale this original mattress in a box comes in right around a 5.5 to 6.5, depending on your size. This is a fairly ideal feel for all sleeping positions, working quite well for most sleepers. Unless you prefer a truly firm feel or a mattress that is more medium to medium-soft, this comfort level should be a good comfort level for most sleepers.

When it comes to the Cocoon Chill mattress you get more options. The mattress comes in two comfort levels, called Medium-Soft and Extra Firm. According to Cocoon, the Medium-Soft feel should fall in between a 3 and 8. While we would have to say that this option falls around a 5 to 5.5  for most average sized people. Putting it right in a spot most ideal for side and back sleepers.

While their Extra Firm option is more of a true firm feel. Cocoon’s rating should fall around a 8 to 10. More than likely coming in around an 8.5 for the majority of sleepers and certainly best for stomach sleepers, back sleepers who like a firmer feel and even larger sleepers.

Casper vs Cocoon – Materials:

The quality and density of these materials will also give some insight into the durability and long term use of a mattress. As well as the value of the bed and if it is worth the price. Below we will give a breakdown of both the Casper materials and the Cocoon materials.

Casper Mattress – Materials:

materials used in casper mattress - not hyrbidThe Casper mattress is 12″ and uses 4 layers of foam. The top layer is going to be made of responsive breathable open-cell foam. This layer is meant to mimic the feel of latex and be more responsive. However, it lacks the durability and natural benefits that latex actually provides. This is followed by another layer of high density memory foam and transition foam. These layers help evenly distribute weight as well as all work together to relieve pressure too.

These comfort layers sit on a base of dense support foam. The cover on this mattress is a little thicker too adds a bit of extra softness. It is breathable as well as has more durable side panels. This mattress will have a conforming yet responsive feel that will be fairly supportive as well.

Cocoon by Sealy Mattress Materials:

cocoon motion transferThe Cocoon mattress is also a 10″ mattress that uses 3 layers of foam. The top layer is going to be 2″ of a very true conforming memory foam. This comfort layer is going to provide great pressure relief as well as a contouring feel that helps distribute your weight evenly.

This is followed by another 2″ of transition foam that will help create a balance and gentle support between the dense base foam and softer memory foam. As well as provide deep comfort and a bit of response for easy moving. These comfort layers sit on a 6″ base of dense support foam. This mattress will have a conforming and hugging feel that will be exactly what to expect from a true memory foam mattress. As well as covered in a premium cover that can be upgraded to a “chill” feel that adds extra cooling benefits too.

Casper vs Cocoon – Our Comfort Pick: 

We know that comfort can be a very subjective area of mattress shopping. However, having a good idea of the materials and feel, or firmness, of a mattress can be a good place to start. Especially when your are objectively deciding which may be more comfortable. This holds true initially, as well as after several years of sleeping too.

casper vs cocoonThese two mattresses vary a bit in the firmness of each. The Cocoon will have a softer and firmer option, with the Medium-Soft leaning closer to a medium feel and the Extra Firm a true firm. While the Casper has a medium-firm feel. The layers of the Cocoon offer a more contouring and slightly more pressure relieving feel. Where the Casper is slightly more responsive with a combo of open cell and memory foam. Giving the Cocoon a more “cocooning” feel over the Casper.

Personally we preferred the feel of the more true memory foam pressure relief of the Cocoon, especially in the soft feel. It does a great job of hugging your body and evenly distributing weight all while still letting you easily change positions. The support also feels more solid and durable making the long term use of the mattress more likely. We found that this mattress did a great job of working great for both of us. Accommodating sleeping on your side and back and even working well while occasionally on your stomach.

Casper vs Cocoon – Motion Transfer:

casper vs cocoonBoth of these mattresses are all foam mattresses and that alone will make for minimal motion transfer. Each of these mattresses are about 10″ of all foam that makes for little vibrations from movement. The Cocoon mattress does have 2″ of memory foam on top that will respond quicker to reduce movement and eliminate it before it travels to your partner. It also offers a thicker portion of base foam that will absorb any extra movement too.

Casper’s top is a more responsive open cell foam layer that is meant to mimic latex and will have a more responsive feel. It won’t be anything overly noticeable, but when comparing these mattresses side by side the Cocoon has slightly less motion transfer than the Casper.

Casper vs Cocoon – Sleeping Cool:

casper corner comfort comparisonAs previously mentioned, both of these mattresses are all foam beds that also have layers of memory foam. Heat retention with memory is a little more prevalent than in a hybrid or latex mattress. Leading to a warmer mattress not long into sleeping. Most mattresses that feature memory foam try to combat these heat retaining properties. Usually by adding gels or off setting the heat with more open celled structures.

Casper Sleeping Cool –

The Casper mattress has a top layer that has an open cell layer of foam that helps pull heat away from the body. The top layer also acts as a barrier between the memory foam and the surface as well. It also uses a woven stretch knit cover that is breathable and meant to dissipate heat. These materials should help reduce some of the heat retention.

Cocoon Sleeping Cool –

cocoon cooling comfortThe Cocoon Chill mattress is Sealy’s answer to the problem for heat retention. The cover of this mattress utilizes thermic phase changing material to help with sleeping cool. The Cocoon mattress has a top layer of true memory foam that may sleep a little warmer. The transition layer doesn’t have any added gels or cooling properties to aid in heat dissipation but will be more responsive to help you not feel stuck. If you are a warm sleeper you will have the option of getting the firm option that will allow you to ride more on top of the mattress. The cool to the touch cover with thermic phase changing material will help eliminate heat. This cover is cool to the touch and also helps to wick away moisture.

Overall, it is tough to keep any all foam mattress cool and hybrids will naturally be a better option for those who are particularly hot sleepers. However, both of these brands have done their due diligence when it comes to ensuring their all foam mattresses sleep as cool as possible. Which is why we gave them a tie in the sleeping cool category.

Casper vs Cocoon – Edge Support:

casper vs cocoonEdge support may or may not be something that is a big concern to you. However, if it is than paying attention to how well constructed and durable the materials are will play a roll. Edge support is important if you either sit on the edge from time to time or if it is important for you to use the full edge to edge sleeping surface of your mattress. Making sure that even the edges are solid and hold up will make a difference in how comfortable it is as well as how it performs for you.

When comparing the Cocoon to the Casper you may notice a bit of variance in perimeter support. While the Casper is okay for sleeping it certainly lacks while sleeping. More than likely due to the thinner layer of base foam and slightly less dense comfort foams on top. This will make you feel like you need to stay in a few inches from the edge while sleeping, cutting down on the full use of the bed. And sitting along the edge will certainly leave you feeling unsupported.

On the other hand the Cocoon has a more consistent and durable feel that translates to overall better edge support. Which is both beneficial for sitting and sleeping. Allowing you full use of the bed that evenly distributes your weight and allows no change in feel whether sleeping on the edge or in the middle. And even sitting on the edge will feel more stable, though its intention isn’t really meant for sitting use. When all is said and done, the edge of the Cocoon will feel more solid than the Casper.

Casper vs Cocoon – Value:

casper mattress and boxThe value of a mattress goes beyond just its price tag. Looking at the components, construction and benefits of each makes a difference when it comes to their value. Comparing these areas to the price gives you a better idea if it is good, bad or great value. Additionally looking at any other added benefits like trial periods length, warranty and customer service also goes into this area.

The Casper mattress is just under $1000 for a queen size and does include the shipping in the price and in home set up. This mattress also includes a 100 night sleep trial and a 10 year warranty. This mattress may be right up your ally, and if that is the case, great. It is a 12″ thick mattress with poly and memory foam comfort layers.

Casper vs Cocoon – Overall: 

cocoon mattress in a boxLooking at both of these mattresses from an impartial perspective we can say that both do a fine job. The Cocoon may check a few more boxes, especially with the options available to choose from. The Casper will have a more medium-firm feel while the Cocoon will have two comfort options to choose from.

When it comes to benefits the Cocoon may edge out the Casper in edge support as well as delivery and off gassing. As far as sleeping cool and motion transfer goes, both will fair similarly. Now when it comes to value, the Cocoon is going to take the cake. While the Cocoon Chill by Sealy gets you better benefits at a more affordable cost, especially when utilizing their coupon.

When all was said and done we preferred the true memory foam feel of the Cocoon by Sealy. This mattress provided good solid support as well as an ideal feeling memory foam. This mattress also comes in at a great price point and the solid brand that stands behind it.
