An upstart mattress company and an industry giant face off in the bed-in-a-box category. Can Sealy produce a mattress as good as the innovative system of Casper or is Sealy too entrenched in its old ways?

In our Casper versus Cocoon review, we’re going to explore both mattresses to see if Sealy can think outside the box enough to get to the heart of the bed-in-a-box spirit, or if Casper’s answer-to-no-one (except the customer) model will prevail. Let’s take a look.

Casper and Cocoon Comparison

Let’s take a look at a few similarities and a few fundamental differences.

How are Casper and Cocoon similar?

Despite being two different models of a company, there are a few similarities between Casper and Cocoon, particularly in logistics (trial periods, manufacturing, warranties, and shipping). Some of the mattress concepts are similar as well.

Packaging and Off-gassing

Both companies compress their mattresses to ship directly to your house. Neither mattress produces much odor although let’s be honest, any mattress wrapped in plastic is going to have a little bit.

Once you unseal it and unroll it, the smell dissipates fairly quickly. Both need a few hours at least to expand fully, so don’t wait around to unpack right before you get into bed. You’ll be at the maximum smell and minimum comfort.

The best thing to do with both mattresses is to allow them to expand fully and air out at least 24 hours before you plan to sleep on them. Since neither company offers white glove service, you’ll still have your old mattress for one more night before switching over. Resist the temptation and leave them both alone until the next day.


Both mattresses use the contour/support method when putting layers together. They don’t have the same number of layers, but the concept is identical. On the top, the contour layer of foam gives into the curves of your body allowing those pressure points to sink further into the mattress.

In conventional mattresses, your body conforms to the bed rather than the other way around. Contouring layers get around this problem, so the mattress takes on the shape of your body instead.

Bottom layers are called support foam. These layers are denser and provide more pushback against your body. If the entire mattress were contouring, you’d sink into a quicksand-like pile. The support layer stops your body from sinking entirely so that your spine is in alignment and supported.

Motion Transfer

Both Casper and Cocoon have excellent motion transfer, almost equal. Casper’s top layer is a latex blend, so it’s a little bit more responsive than the Cocoon. People who want a little bit of bounce without too much overall motion will find the Casper closer to what they’re looking for.

The Cocoon goes all in with an ultra conforming top layer, particularly in the soft option. It does imitate the “hug” of an original memory foam mattress, so if you want zero motion transfer, it nails that preference.

Despite the slight difference in the top layer, both do reduce motion transfer down to nearly nothing, so couples (or pet lovers) should get a lot of peace in spite of a partner or pet’s tossing and turning.


Both mattresses have a pretty high rating for durability. Casper hasn’t been around that long, so it’s still a matter of debate about whether these mattresses will last in the long run. However, since the company’s beginnings, there have been few complaints in the three to five years most people have owned their mattresses about small wear and tear such as ripped seaming or indents in the foam.

Cocoon is a new mattress, but not a new company. Sealy has excellent ratings for mattress durability. Even if this is a new mattress offering, we feel confident in Sealy’s ability to put out a durable mattress.


Both Cocoon and Casper are pretty close regarding overall cost. The Casper original and the Cocoon Chill option are the same price point with the California King coming in at less than $1200.

Casper and Cocoon also offer a budget option. Casper’s Essential line has a California King at less than $800, but the Cocoon original is a little higher at less than $1000.

Overall, the average cost of the mattresses is in the same tier. Both companies offer free shipping.


Both companies offer financing options over the course of a year if the full price of the mattress is out of your reach right now. You can complete the financing directly through the website on the same day and proceed to checkout.

Trial Periods and Warranty

Both companies offer a 100-day trial period for you to decide if your new mattress meets all your needs. Casper asks that you sleep on your new bed for at least 30 nights before initiating a return, but Cocoon doesn’t.

When you initiate a return, both companies take the mattress back free of charge and issue you a full refund. Cocoon allows a one-time transfer to switch to a different bed as well.

Both companies have a limited ten-year warranty for defects and some wear and tear. They both reserve the right to issue exchanges at their discretion.

Manufacturing and Customer Service

If US manufacturing is essential to you, take heart. Casper’s mattresses are manufactured in the United States with some components coming from abroad. Cocoon is also made in the US and mattresses ship from the Mississippi facility.

Customer service experiences can make or break a relationship with a company, even if the products are fantastic. Not to worry, here. Neither customer comments about their customer service, but it appears that both are mostly based in the United States.

How are Casper and Cocoon Different?

Fundamental differences exist between the actual layers of Casper and Cocoon mattresses as well as the firmness levels.


The original Casper has four different layers of foam. The top two layers are contouring foams with the first layer being an open cell latex blend that’s responsive (bouncy). The third layer is zoned support with firmer foam under your hips and softer foam under your shoulders. The fourth layer is the dense support base layer.

The Casper Wave has five layers with an extra layer of hyper-targeted support under the lumbar region. Their budget option, the Essential, has only three layers of basic contouring and support foam.

All of the Cocoon options have three layers. The first layer of foam is the contouring layer. It provides the full sink of traditional memory foam. The second layer is a “comfort layer.” It’s firmer or softer depending on your mattress preferences. The final layer is dense support foam.

Mattress Styles

Let’s talk a little more about what each company offers you in mattresses.

The Casper Original

The original Casper is a four-layer memory foam mattress with two contouring layers and two support layers. It has a zippable cover meant to help disperse heat and make cleaning the mattress a little easier. The third layer is a zoned support layer, meaning your shoulders get to sink into the bed a little deeper than your hips will. Overall, it comes to about a six on a ten-point firmness scale.

The Casper Wave

The Wave takes things a little bit further by adding a targeted support layer. This layer is similar to zoned support, but it offers even more support for the lower lumbar region. It’s intended for people who experience a lot of pain during the night in their back but still need the contouring action of memory foam for other pressure points.

The Casper Essential

Casper’s budget mattress strikes a balance between a smaller budget and comfort. If you don’t have any outstanding sleep issues, the Essential offers basic contour and support foam in three layers. The entire line comes in under $800.

The Cocoon Original

The original Cocoon has three layers of foam in the basic contour and support set up but with one significant difference. The middle layer of foam is firmer or denser depending on your sleep preferences.

With the soft middle layer, the mattress is about a 4.5 on a ten-point firmness scale. The denser middle layer moves the bed up to about a seven on a ten-point scale. This wide range gives you a lot of choices as far as your sleep preferences go.

The Cocoon Chill

The Chill features the same set up on the inside of the mattress, contour layer, soft or firm option layer, and dense support layer. The cover is what makes this mattress. It’s a material that’s so good at wicking away heat and dispersing it away from your body that the cover feels almost wet to the touch (in a good way). We aren’t sure exactly how to describe this cover, but it is one of the coolest touch options on the market.

And the Winner is…

Cocoon. Total Upset. Buy Online Now

We’re confident recommending Cocoon as the best choice based on our analysis of critical factors that an average, discerning mattress shopper would care most about. It’s rare that an established company can see the writing on the wall and completely reinvent a product to match what consumers are looking for.

We love the Casper. We do. However, one beef we’ve had with the mattress-in-a-box phenomena is that we don’t get to choose what firmness level we’d like because memory foam is intended to hit the middle of the spectrum.

Casper produces some great mattresses, yes, but when we learned we could customize our own sleep experience based on what we want and not what a company tells us is comfortable? Priceless.

The Chill layer is a bit of magic on top of this decision. It’s nothing fancy, and nothing feels different from the regular mattress’s support, but that cool touch material keeps even the soft mattress from reflecting heat back onto our bodies. We can get a super soft mattress with plenty of “hug” without sweating to death halfway through the night. It’s brilliant.

For Sleepers With Specific Needs

And now the breakdown for your specific sleep concerns. Here are our targeted recommendations.

Side Sleepers: Choose Cocoon

Here’s why. Although Casper offers targeted support layers in its mattresses intended for side sleepers, the softer feel of Cocoon’s Soft mattress more closely aligns with a side sleeper’s pressure points while supporting the spine. You get an overall contour that fits you regardless of your specific side sleeping position.

Stomach Sleepers: Choose Cocoon

Here’s why. The Cocoon firm is slightly firmer than the Casper, so it keeps you from overextending your spine in the superman position. It also has a slight edge in edge support (see what we did there?), so you can hug the side as close as possible without feeling like you’ll fall off.

Back Pain: Choose Cocoon

Here’s why. We’ve recommended Casper in the past for back pain sufferers because in a world of bed-in-a-box mattresses with no soft to firm options, the targeted support layer was a game changer. Now that you can choose an ultra-firm mattress, our preference is Cocoon.

Heavy People: Choose neither

Here’s why. Neither mattress is intended for those on the heavier end of the spectrum. The Cocoon soft is going to offer almost no support. The firm is going to feel too firm. Casper has no options at all. It’s not going to work. We suggest checking out Winkbed’s Plus mattress for a bed that considers your specific needs.

Couples Choose: Casper

In the only recommendation that goes towards Casper, we recommend Casper’s combination support if you can’t agree on what kind of mattress to get. The zoned support helps hit both targets. If you can decide on a firmness level, choose Cocoon.


Sealy did an outstanding job of listening to the market and providing something that other bed-in-a-box brands were lacking, a firm (well, medium firm) and soft option. It edges out the Casper in that area and Cocoon’s better temperature regulation.
