Cocoon Classic Buying Experience

In the online mattress industry, there’s a fairly standard group of policies in regards to shipping, returns, warranties, and all those things. It’s pretty fair to expect free shipping, free returns, a 100-night trial period, and a 10-year warranty—and that’s exactly what you get from Cocoon when you purchase their Classic mattress.

Your bed is going to arrive in a box about the size of a small refrigerator. To get it into that box, the bed had to be rolled and compressed in a vacuum-sealed plastic wrap. Once your bed shows up, you’ll want to get it unboxed as soon as you can. Remove the plastic wrapping and allow your new mattress to take shape wherever you want it, whether that’s on a bed frame or on the floor (because you just moved or you’re just not in the right phase of life for a bed frame).

It can take up to 72 hours for your bed to fully expand, so don’t worry if you pull it out of the box and it looks a little sad. It also might have a strange new-mattress smell, but that’s normal with almost all bed-in-a-box mattresses and not a sign that you’ve received a rotten bed. The smell should dissipate in a day or so.

Cocoon Classic Price And Coupon Code

Compared to a lot of the other mattresses you’ll be shopping for onlineCocoon Classic is an affordable option. You can find a breakdown of the pricing by mattress size in the table below.

SizePrice (MSRP)
Twin XL$449
King / Cal King$999

Because the online bedding industry is so competitive, a lot of brands are forced to offer mattress deals to sweeten the pot. Sealy, despite being a behemoth in the mattress space, will offer discounts on their mattresses. You can check the Cocoon website for current promotions. The sales change from time to time, but usually they offer some sort of cash discount as well as bundle in a free pillow or sheets.

Several Layers Of Foam

Cocoon Classic is a 10″ all-foam bed with two to three layers of material, all wrapped up in a soft, stretch-knit cover. This mattress comes in two different firmness options, so the construction changes a bit depending on which you opt for.

Let’s break it down. First up, there’s a base layer of “Essential Support Foam.” This is the bed’s thickest layer and provides the foundation for the mattress. Next is the “Personalized Comfort” layer, which isn’t actually personalized, but it is the layer that changes based on which firmness option you choose (Soft or Firm).

If you get the firm model, you lose the transition layer and the base layer goes from 6″ to 8″ so that the bed is still 10″ in total. What happens here is that there’s less material between you and the dense support foam on the base, which is why the mattress feels firmer.

Firm model has only two layers

The mattress is topped by a “Perfect Fit Memory Foam” layer, which is just a fancier way of saying memory foam that conforms to your body.

All in all, there’s nothing overly unique about the Cocoon Classic mattress, but then again, it’s really affordable so that’s sort of to be expected. It is nice, however, that you have the option between two firmness levels. Most budget mattresses come in one firmness level and that’s it. For example, Zinus, Tuft & Needle, and Lucid are all equally as Plain Jane as Cocoon Classic, but only come in one firmness level.

We Like The Cover’s Design

The cover on the Cocoon Classic mattress has a nice soft feel and it is removable, as are most mattress covers. However, we don’t suggest you actually take it off because it isn’t machine washable and is ultimately just an unnecessary hassle.

If you do need to clean up any spills or stains, though, you can spot clean with warm water and some mild detergent.

If you have an older mattress, you may be used to flipping and rotating the bed now and then, but with Cocoon Classic, there’s no need to do either. In fact, you should not flip it because it’s constructed with the layers in a non-reversible order. With regard to rotating the bed, you can do that, but it’s not absolutely necessary. If you’re sharing your mattress with a partner, however, it might a good idea to rotate the bed periodically so that it wears evenly.

What Cocoon Classic Actually Feels Like

As we mentioned earlier, this mattress comes in two different firmness options: Soft and Firm. Despite their given titles, though, we actually think the Soft option feels like a medium or a medium-firm, and the Firm is only slightly firmer. Also, keep in mind that memory foam tends to feel firmer when in a colder room and softer in a warmer room. This is partly the reason that we have softness/firmness on a range in the graphic below.

The Cocoon Classic definitely has a dense memory foam feel. When you first lay on the mattress, you don’t sink in. It actually takes a few seconds for the foam to soften up and contour to the shape of your body. This is standard with any firmer memory foam mattress, including Nectar, Novosbed, and many others. We think the bed is comfortable, but it’s not a mattress that prompts you to say “aaahhhhhh” when you first lay down.

As you can see, the bed is slower to respond to pressure being applied and removed. This really just boils down to, do you like memory foam? If yes, you’ll probably like the feel of this mattress. If no, then you won’t like Cocoon and you should check out some of our other mattress reviews.

Let’s Focus In On Sleeping Positions

We do think Cocoon Classic is a good mattress for back and stomach sleepers. Its dense memory foam feel and level of firmness means it provides enough support to keep the spine in neutral alignment when sleeping on your back or stomach.

We would go as far as to say that back and stomach are the two most ideal sleeping positions for this mattress. At one point, we even selected Cocoon Classic as our “Best Value” pick on our list of the best mattresses for back sleepers.

For the same reasons this is a good bed for back and stomach sleepers, Cocoon Classic isn’t the best option for side sleepers. The density and firmer feel mean you won’t get as much pressure relief for the protrusion of your shoulder and hip while sleeping on your side.

That said, if you’re close to 225 lb, you should be fine sleeping on your side even though it might not be your favorite mattress of all time. Certainly, if you plan to sleep on your side, you should be looking at the Soft model.

If you’re a combo sleeper, you’ll be okay on this mattress. It doesn’t have the best responsiveness, so you may feel a bit stuck when you go to switch positions, but that’s generally the case with memory foam beds. We think that as long as you spend most of your sleep time on your back and/or stomach, Cocoon Classic will work for you just fine.

The other thing to consider is that some restless sleepers really like memory foam because it makes them feel secure. Because the mattress is slower to respond to pressure, it creates a little nook or indentation for your body. As such, you’re not as inclined to want to switch sleeping positions.

All this is to say that we could see combination sleepers really liking, or not liking, this mattress. It all just depends on the individual sleeper.

A Foam Bed That Might Work For Heavy People

There is no yes or no answer here—it’s more complicated than that. Because this bed is fairly dense and on the firmer end of the spectrum, it’s more ideal than a good number of all-foam beds, but we wouldn’t put it on par with Big Fig or WinkBed. This isn’t an especially thick mattress at 10” (which is just about average), but overall we do think the mattress will be durable. Again, not ideal for heavy people, but better than beds like Layla since this one is firmer.

Not designed for heavy people, but it will work in a pinch

We will note that heavier people are going to find this bed softer than lighter folks. The more weight you put into the mattress, the softer it feels and the more you sink it. So if you have a larger build, it is important that you do like the sink-in feature of memory foam. We’d also suggest you definitely opt for the Firm version of this mattress.

It’s Made For People Under 250 lb

We think the Cocoon Classic is a good choice for medium and petite sized people. But, again, mattress feel is affected by your weight, so if you’re quite small, just know that the bed will likely feel firmer to you. If you’re not interested in a firm mattress, go for the Soft version.

The Chill Model Is A Cool-Sleeping Bed

No, it doesn’t sleep hot, but we wouldn’t say that it sleeps noticeably cool. Rather, we’d call this mattress temperature neutral. In all honesty, temperature regulation is affected by more than just the materials in a mattress. While Cocoon Classic uses memory foam, which is usually a warmer material, it is a bit firmer, which will prevent the mattress from wrapping/hugging your body. The heavier you are, the warmer you’ll sleep on this bed—the opposite is true for petite individuals.

If you’re looking for a mattress that truly does sleep cool, you might want to check out the Cocoon Chill. The only difference between the Classic and Chill models is that the Chill has a phase-change cooling cover and costs $50 more. You can see the Chill model on the Cocoon website.

A Section Just For Couples

The Cocoon Classic is a pretty good choice for couples, although there’s always the chance that one person likes memory foam and the other doesn’t. When you’re sharing a bed, there’s a lot to consider, but you want to think about edge support and motion isolation in particular.

The edge support on this mattress is fairly good, which means that you can sleep on those outside inches of the bed without feeling like you’re about to roll off. That roll-off issue can be a problem when you and your partner share a smaller bed, like a full or a queen. Inevitably, one of you is going to end up ousted to the bed’s edge, and supportive edges will help make that situation a bit better. Usually edge support is an issue with softer coil or foam beds. Typically, firmer beds do a better job here.

No major roll-off sensation

Cocoon Classic is good at isolating motion thanks to that top layer of memory foam. Motion isolation refers to how well the mattress limits cross-bed motion. Think back to those mattress commercials with the glass of wine that doesn’t spill when the pretty lady jumps on the other side of the bed—that’s motion isolation.

As you can see, the water doesn’t stay completely stagnant, but a lot of the movement is actually due to the entire mattress moving rather than motion transferring through the bed.

Couples want a bed with good motion isolation so that one partner can get up for a midnight bathroom run (or a midnight snack) without waking up their better half. Motion isolation is also important if one partner is an active sleeper and tends to toss and turn throughout the night. Again, you don’t want the other person to wake up because of the movement.

Cocoon Classic Review: Verdict

When it comes down to it, the Cocoon Classic is an affordable all-foam mattress with a dense memory foam feel. It’s suitable for back, stomach, and combo sleepers. It comes in two firmness options, which gives you a little bit of customization, though we think the Soft and Firm versions are fairly similar.
