Cocoon vs Casper Mattress Overview

Casper was one of the pioneers in the bed-in-a-box mattress space. Despite the fact that the company has only been around since 2014, its standard Casper mattress is largely considered one of the best online mattresses, and the company as a whole is valued at nearly $1 billion. Sealy, however, is one of the most longstanding and trusted brands in the mattress industry. It designed and tested over 100 prototypes for two years to join the shippable mattress competition until it found the successful formula.

Cocoon by Sealy and Casper are both toward the top of the list of most popular online mattresses, but for different reasons. In this review, we’ll discuss Casper vs Sealy and how they directly compare, particularly as it relates to firmness, design, feel, and price.

Here are the key elements that you need to know when considering Casper vs Sealy.

  • Feel: Casper has more of a neutral feel, while Cocoon has a dense memory foam feel.
  • Price: Before and after discounts, Cocoon is more affordable.
  • Support: Casper has a special transitional layer that offers support and pressure relief exactly where you need it.
  • Cooling: Only Cocoon has an active-cooling mattress for hot sleepers.

Casper Mattress Review

Casper Construction And Materials

As you can see above in the construction breakdown below, the flagship Casper Mattress is an all-foam bed broken down into three layers.

casper mattress review original construction
Inside the original Casper mattress
  • The bed starts with a standard layer of support foam which acts as the bed’s foundation
  • Next is a layer of memory foam to neutralize the harsh feel of dense foam underneath
  • The third layer is made from the brand’s proprietary foam which acts and feels like polyurethane foam — neutral and responsive

Casper Feel And Firmness

The overall firmness rating for this bed sits at medium and it stikes a nice balance between being supportive and pressure relieving. As a result, we think it will be great for back, stomach, side, and combination sleepers. It is a versatile, nearly universally loved mattress.

Since Casper Mattress only has one layer of memory foam, and it’s located underneath a layer of neutral polyurethane foam, the overall feel of the bed is classic and neutral. Overall, it’s a really comfortable mattress that’s more breathable and responsive than a typical memory foam bed.

Is Casper Mattress Good For Couples?

Edge Support

All-foam beds like Casper usually don’t have the most phenomenal edge support, but it’s not bad either. We think it gets the job done fine, but if you want extra support, check out Casper’s hybrid beds.

Motion Isolation

Like most beds made with only foam, Casper preforms great in this category and absorbs motion very well.

Casper Wave vs Cocoon

Casper also offers hybrid mattress models such as the Casper Wave that are more fitting for heavy individuals or folks who want additional support. It has a similar neutral feel and medium firmness level like the original Casper bed, but it’s designed with five layers instead, including a supportive pocketed coil layer and perforated Talalay latex foam. Though, it is much more pricey than the OG Casper model.

Cocoon By Sealy Mattress Review

Cocoon Construction And Materials

Cocoon is a 10″ thick mattress and the exact construction will depend on the type of firmness you choose; “Softer” or “Firmer.”

cocoon by sealy review construction whats the mattress made of
A look inside the Cocoon mattress (Soft model shown)
  • Regardless of the model, each one will start with a thick layer of support foam
  • The soft model includes a transition layer in the middle which softens the bed just a hair
  • The firm model, on the other hand, does away with that center strip of foam and increases the thickness of the support foam. The net result is a slightly firmer bed.
  • The top slab of foam is made with memory foam and acts as the true comfort layer of the bed.

Cocoon Feel And Firmness

While Casper has more of a neutral feel, Cocoon has a dense memory foam feel. In fact, it’s firmer when you first lay on it, but it does soften after a few seconds and conform to the shape of your body. This viscous, hugging feel is typical of traditional memory foam mattresses like Nectar or TempurPedic.

The one downside of dense memory foam for some sleepers is that you do get a slight stuck-in-the-mud feeling with the Cocoon mattress.

As far as firmness goes, we rated the Softer model in between medium and medium-firm, while the Firmer model lands around a medium-firm. In short, if you compare Casper vs Cocoon, Cocoon is the firmer mattress between the two.

Cocoon Mattress Temperature

Anyone who gets hot flashes, nights sweats or sleeps hot at night will appreciate that Sealy offers the Cocoon Chill mattress, which is a cooler sleeping mattress than both the Classic Cocoon Mattress and Casper. This costs about $50 more than the original model, but it has a special cooling cover that’s cool to the touch.

We should also mention that Cocoon Chill is one of the most affordable active-cooling mattresses available. In fact, the cover is so cool-to-the-touch that it almost feels wet. Cocoon Chill might not be as cool as Brooklyn Bedding Aurora or the Freya mattress, but it is far more affordable.

Is Cocoon A Good Mattress For Couples?

Edge Support

Similar to Casper, Cocoon offers ample edge support for couples who share a mattress with a partner. It’s not the best we’ve ever seen because the bed is made with all-foam, but it’s still good enough to get the job done.

Motion Isolation

Memory foam tends to be great at isolating motion (think back to those old TempurPedic commercials where a woman jumps on a mattress right next to a glass of wine). As such, Cocoon passed out motion isolation test with flying colors.

Cocoon Chill vs Casper

If you compare Cocoon Chill vs Casper, you get two all-foam bed in a box mattresses that feel very different from each other. Cocoon Chill has a firmer profile with a memory foam feel while Casper is a tad softer and feels like responsive, neutral-foam. Cocoon Chill is also a cooler sleeping mattress for hot sleepers who tend to warm up during the night. Lastly, after discounts, Cocoon Chill tends to be the more affordable bed.

Casper vs Cocoon Mattress Pricing

For anyone who is especially price-conscious, Cocoon is the obvious choice—assuming that you’re fine with the mattress’ feel and firmness. The MSRP of a queen-size Cocoon Chill mattress is about $950 before any discounts. Casper, for the same size, is about $1,100. See the table below for a full cocoon vs casper price comparison.

SizeCasperCocoon
Twin$595$600
Twin XL$695$650
Full$995$760
Queen$1,095$930
King$1,295$1,150
Cal King$1,295$1,150

For college students, anyone trying to fill a guest room or Airbnb, or budget shoppers, Cocoon is probably the smarter pickup. Having said that, both brands do offer coupons to make their beds even cheaper, and Cocoon tends to be more aggressive with theirs.

Sleeper Type Analysis

Not every bed is designed to suit all bodies and sleeping positions. In this section, we’ll break down who we think Sealy vs Casper work best for according to the different body and sleeper types.

Side Sleepers

Side sleepers typically prefer softer, more pressure reliving beds that contour to the curves of your body. While neither Casper or Cocoon were rated on the soft end of the spectrum, Casper has a slightly softer mattress profile that’s a bit more suitable for side sleepers. Though, heavy side sleepers should be just find on either bed.

Back And Stomach Sleepers

Considering we rated the soft and firm models of Cocoon around the medium-firm range on the soft/firm spectrum, we think they’ll be better suited for back and stomach sleepers who prefer a more supportive firmness level.

Combo Sleepers

In truth, combination sleepers can opt for either Casper or Cocoon — it ultimately depends on how soft or firm you want your bed to be. If you favor your side, you might want Casper or the Softer model from Cocoon. Those who predominately sleep on their back or stomach may want to opt for Cocoon’s Firmer model. Or, you can choose Casper which lands right in the middle of the spectrum to accommodate all sleeping positions.

Heavy Individuals

If we’re being honest, we think folks who weigh over ~230 lbs should look elsewhere. Neither Casper or Cocoon have particularly supportive or durable constructions like hybrid beds do. As such, we recommend Casper Wave or another hybrid mattress that’s made with innersprings or pocketed coils.

Petite To Average Individuals

Those who weigh under ~230 lbs will find foam beds like Casper and Cocoon to be accommodating enough for their weight, so we don’t think these body types will have any issues with either bed.

Cocoon vs Casper Mattress Review Verdict

For the most part, it all comes down to feel, firmness and price. Do you want a neutral-foam bed? Do you like memory foam? Which sleeping position do you favor? What’s your budget?

If you’re open to spending a little more, but want the more popular, more neutral feeling bed, go with Casper—we doubt you’ll be disappointed. After all, there’s a reason that Casper is worth nearly a billion dollars.

If you’re a fan of memory foam and you tend to sleep on your back or stomach, Cocoon is the way to go—it’s a nice mattress for the moneySealy knows what it’s doing, even if the Cocoon mattress is a relatively new product.
