Purple vs Cocoon Sealy Mattress

Should you go memory foam in the case of Sealy Cocoon or something new with Purple?

Although Purple and Cocoon are two of the most popular bed-in-a-box mattresses, they're actually quite different. Purple is a new-age mattress company that has achieved tremendous success, while Cocoon is backed by the bedding giant Sealy. In this post, we put the Original Purple mattress to the test against the two Cocoon beds.

Purple Mattress vs Cocoon By Sealy Synopsis

Here are the primary differences between Purple and Cocoon.

  • Feel — The Original Purple has a very unique, gel-like feel, while the Cocoon beds have a firm, memory foam feel.
  • Price — The Cocoon mattresses are quite a bit more affordable than the Original Purple bed.
  • Firmness Options — Cocoon allows you to choose between two different models (Classic and Chill) and firmness levels (Soft and Firm). The OG Purple comes in just one feel (medium).
  • Temperature Regulation — Purple beds allow for great airflow, while the Cocoon Chill has a special phase-change material in its cover, which helps keep you cool.
  • Sleeper Type — The Original Purple mattress is more accommodating for side sleepers.

Those are just the quick hit headlines, though. There’s a lot more detail about each bed that you’ll want to check out. Keep reading to learn more.

  • Hot sleepers

The Original Purple Mattress Has A Gel-Like Feel

As we alluded to above, the Original Purple mattress has a very unique feel. In fact, all Purple beds do, including the Purple.2, Purple.3, and Purple.4 mattresses.

This is because all Purple beds use the company’s patented Hyper-Elastic Polymer for their top layer. This polymer material is not a foam. It’s actually more of a gel or silicone-like material (although it’s obviously polymer). Nevertheless, Hyper-Elastic Polymer is very unique in that it’s stretchy, soft, and responsive, yet it’s also quite supportive. Purple likes to say it’s “soft where you want it and firm where you need it.”

As you lay down on the bed, you can feel the polymer below compressing, folding, and conforming to your body’s shape. I’ll be the first to admit that, initially, this sensation is a little weird. However, after spending a few nights on the bed, we’ve found most people end up really liking the feel of it. It’s one of those things where when you try and like it, you never go back to traditional mattresses. Just ask Slumber Yard team member Matt who sleeps on the Purple 4.0 model every night.

The Purple Bed Is Very Responsive

As we stated above, the Purple bed is very responsive thanks to its top layer. The Hyper-Elastic Polymer is very flexible and snaps back to position immediately after pressure is released. In fact, the polymer material can be stretched 15x its original state and will instantly pop back. It’s pretty incredible.

All this is to say that active sleepers who move around a lot will generally find responsive beds much easier to switch between sleeping positions. As you will find out below, the Cocoon mattresses are a little slower to respond thanks to their memory foam top layers.

Better For Side Sleepers

Overall, we think the Original Purple mattress comes in around a medium on the firmness scale. The bed strikes a very nice balance between pressure relief and support. The Cocoon mattresses (both firmness options), on the other hand, are a bit firmer than the OG Purple bed, despite having memory foam top layers.

Lots of pressure relief for side sleepers

As such, we think Purple is more ideal for strict side sleepers. The Hyper-Elastic Polymer is very soft and does a great job of cradling your hips and shoulders when you’re on your side. In fact, Purple even made our list of the Best Mattresses For Side Sleepers.

Hyper-Elastic Polymer Allows For A Lot Of Airflow

Another benefit of Hyper-Elastic Polymer is that it excels in terms of temperature regulation. First, Hyper-Elastic Polymer is naturally a temperature neutral material. It simply does not retain and radiate heat the same way a lot of common foams do (e.g. memory foam). Second, the polymer top layer is laid out in a grid formation. This creates columns and rows of tiny polymer squares (pockets) where air can move freely throughout the top of the bed.

More airflow than allowed by law

Cocoon doesn’t take a complete loss here, though. As you will find out below, you can choose between the Cocoon Classic and Cocoon Chill models. The Chill model uses a special phase-change material in the cover that makes the bed literally cool to the touch.

All in all, both of these beds landed on our list for the Best Beds For Hot Sleepers.

Multiple Models And Firmness Levels

What’s nice about Cocoon is that you can choose between a couple different models and firmness levels. There’s the Cocoon Classic, which is their most affordable bed. Then there’s the Cocoon Chill (mentioned above), which is specifically designed for hot sleepers.

Once you choose which model you want, you can choose your firmness level. Cocoon offers Soft and Firm version of both beds.

Cocoon Has A Firm Memory Foam Feel

Regardless of which Cocoon model you choose, both beds have a firm memory foam feel. Don’t let me scare you off with the “firm” designation—the beds are still soft and comfortable, you just don’t sink in as much as you do with a lot of other memory foam beds.

Firm, memory foam feel

All in all, Cocoon actually reminds us of the popular Nectar mattress, which is another firm memory foam bed. If you like memory foam, chances are you’ll like the Cocoon mattresses. As you lay down on the bed, it takes a second or two, but the top layers will start to wrap your body a little. I know a lot of folks really like this type of feel.

It is worth mentioning that we tested both firmness options (Soft and Firm) and we found that both actually land on the firmer side of the spectrum. We rated the Firm version around a medium-firm on the firmness scale, while the Soft version lands a little closer to medium.

Cocoon Mattresses Are More Affordable

This is pretty straightforward. The Cocoon mattresses are much more affordable than the Original Purple. The Cocoon Classic is about $200-$300 cheaper, depending on which size mattress you’re looking for. Next, the Cocoon Chill is about $100-$200 less expensive than Purple, again depending on which size you select.

However, those prices are just based on MSRPs. You can almost always find some sort of Cocoon coupon code or promo code to make the mattresses even cheaper. Check the green box on the right side of the screen to see what kind of promotion the company is currently running.

Purple isn’t too keen on sales, but they do almost always toss in a free gift (pillow, sheets, seat cushion, etc.) with each mattress purchase. Check to see what they’re currently offering.

Better Edge Support

We also think the edge support is a little more solid on the Cocoon mattresses. As you roll over towards the side, there’s very little compression and you never feel as if you’re going slide right off the bed.

This is an important subject for partners who share a smaller size bed, like a full or queen. Beds with solid edge support mean there is more room for both partners to spread out and still feel like they’re being properly supported near the edges.

To be fair, the edge support on the New Purple mattresses is much better than the Original Purple. The new models use dense foam side rails around the perimeter of the beds.

Cocoon Sealy Mattress vs Purple Review Verdict

You made it through the long, arduous journey of a Slumber Yard comparison. Thanks for sticking with us to the end. If you’re still stuck between these two mattress brands, ask yourself a few questions to make the decision easier.

First, how much are you willing to spend? If you’re on a tight budget, go with the Cocoon Classic. That model is an excellent value.

Next, which type of feel do you like? Do you want a memory foam feel or something that is very unique? That’s up to you. It’s purely a personal preference decision.

Next, how much do you sleep on your side? If you spend a lot of time on your side, go with Purple. The Hyper-Elastic Polymer top layer does a great job of cradling your pressure points.

Finally, do you sleep hot? If so, do you want a bed that is cool to the touch or provides excellent airflow? We’d say go with the airflow (i.e. Purple).

That’s all we’ve got for you. We hope it was helpful. Thanks for choosing the Slumber Yard!

What Purple And Cocoon Have In Common

As you’ve read above, Purple and Cocoon differ in several ways. However, they do have some similarities, as well. Here’s where these two mattresses overlap.

Back And Stomach Sleepers

As you read above, we think the Original Purple is better for side sleepers, but when it comes to back and stomach sleepers, we think both beds are good choices. Both Cocoon and Purple provide a good amount of support under your lower back and trunk.

Heavy body types (people the weigh over 250 lb) are a different story, though. See below.

There Are Better Options For Heavy Sleepers

We generally like to point big folks towards beds that use coils for their support structure. Sadly, the Original Purple and Cocoon mattresses do not use coils. Instead, both beds use a dense foam for their foundations.

Beds that contain coils tend to be more durable and supportive than all-foam beds. As such, there are better options out there for heavier people. We’d recommend taking a look our list of the Best Beds For Heavy People if you’re a person that weighs a lot.

If you’re a big person and you are leaning towards Purple, don’t worry, the Purple 2.0, Purple 3.0, and Purple 4.0 all use pocketed coils and are great options for large individuals.

Good Motion Isolation

Last up, both beds do a good job with motion isolation. They both passed our tests easily.

Motion transfer is an important topic for couples to consider. A bed that deadens movement well means you won’t be disturbed by your partner’s movements. In other words, you won’t be jostled awake every time your partner rolls over or gets up. Luckily, both Purple and Cocoon perform well here.

The Buying Process For Each Bed

Over the last several years, online mattress brands have made a conscious effort to make things very easy for consumers. Don’t believe me? I bet you will by the end of this section. Let’s start with Cocoon.

The Cocoon mattresses ship for free and will arrive compressed and rolled up in a medium size box. Once the mattress is delivered, simply move the box to your room and unroll the mattress onto your bed frame or foundation. Be sure to let the mattress fully inflate for about 24-72 hours before using.

Once the mattress is delivered, Cocoon gives you a 100-night risk-free trial period. This is how these online mattress companies get around not having thousands of retail stores for you to peruse. Instead of five minutes in a store, they’re basically giving you around three months to test the bed in your own home to decide whether you like the bed or not. Pretty cool, right?

If you decide you don’t like the bed during the trial period, no worries, just contact Cocoon and they’ll take care of you. They’ll arrange for a third party crew to come pick up the mattress from your home. From there, just provide proof the mattress has been picked up and the company will issue you a full refund. Cocoon also backs their mattresses with a 10-year warranty. You can get more details about the warranty on the company’s website.

Purple, like Cocoon, also offers free shipping, free returns, a 100-night risk-free trial period, and a 10-year warranty. Really, the only difference is that the Original Purple doesn’t arrive in a box. Instead, it just comes rolled up in a protective bag.
