Cocoon by Sealy and Casper are both on the list of the most popular online mattresses. In fact, they're both toward to the top of that list. And for good reason—these are pretty nice mattresses at affordable price points. In this review, we discuss how Cocoon and Casper directly compare, particularly as it relates to firmness, design, feel, and price.

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 a successful formula.

Cocoon by Sealy and Casper are both at 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.

Casper vs. Cocoon Construction

As you can see above in the construction breakdown below, the flagship Casper Mattress is an all-foam bed broken down into three layers. It’s about 11″ thick, slightly taller than the Cocoon Chill mattress.

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. It also features a zoned construction to provide added pressure relief and support where you need it most.
  • The third layer is made from the brand’s proprietary foam, which acts and feels like polyurethane foam — neutral and responsive.

Cocoon Chill, however, is a 10″ thick mattress with a similar 3-layer construction. If you opt for the Cocoon Hybrid, you’ll have a 12″ mattress with a pocketed coil base layer.

What Do Casper And Cocoon Feel Like?

The overall firmness rating for Casper sits at medium, and it strikes a nice balance between being supportive and pressure relieving. We think it’s a very safe pick since it’s so versatile — there’s a reason why it’s so popular!

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.

While Casper has more of a neutral feel, Cocoon Chill 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.

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.

Twin XL$695$650
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. You can check offers on Casper’s website and the deals running on the Cocoon website.

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.

Body Type Analysis

  • 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.

Other Considerations

We also tested edge support, motion isolation, and temperature for each mattress. These are important factors for those who share a bed or sleep hot during the night!

Edge Support

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

Motion Isolation

Memory foam and polyfoam tend 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 Chill and Casper passed our motion isolation test with flying colors.

Mattress Temperature

Anyone who gets hot flashes, night sweats, or sleeps hot at night should appreciate the Cocoon Chill mattress, which is a cooler sleeping memory foam mattress. 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.

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? Do you sleep hot?

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 or you sleep hot, and you tend to sleep on your back or stomach, Cocoon Chill 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.

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.
