  • Cocoon and Casper mattress comfort

Casper comes in one comfort option. The medium firm; this works for the bigger clientele since it lands right on to our favorite spots regardless of your size or sleeping position. On the international firmness scale, Casper hits 5.5-6, giving the mattress an indisputable universal feel.

The Casper mattress tends to be more responsive compared to the Cocoon, therefore, it is quite ideal for sleepers who switch positions a lot. We all like variety and Sealy gave us exactly that. Cocoon mattresses come in two comfort options that you can choose from. Amazing, right?

You can either choose between a medium soft comfort option which is the most popular among the two and an extra firm version. On the firmness scale, the Medium soft comfort sits at a 5-5.5 whilst the Extra firm sits at a cool 8.5. (It is important to note that on this scale 1 is Soft, while 10 is Extra firm)

The medium-soft options tend to favor more sleepers compared to the extra firm option. This does not mean that people don’t prefer the extra firm option; some do and Sealy is there to cater to the minority too. The medium-soft is highly recommended for average-sized sleepers who prefer sleeping on their back more, however, this does not mean that you cannot sleep on any other position; yes, you can.

The extra firm will be the ideal sleeping solution for average-sized to heavy sleepers who fancy sleeping on their backs or stomachs. If your preference in a mattress lies on maximum pressure relief and a softer feeling, then the Cocoon medium-soft is for you, however, for most people the single options work perfectly.

  • Material used on Casper Vs Cocoon

The outcome of any product is fully dependent on the material used to make it. This does not exclude mattresses. What a mattress is made of will play a huge role in its comfort, durability, and performance.

Different types of mattresses will feel different; even a Casper and Cocoon will feel different as much as both are all-foam mattresses. Both manufacturers use different types of foam with a combination of other materials to create a different and unique feel for their specific suitability.

Casper’s original design consists of a four-layer all-foam design with a base layer of dense support foam that offers a stable foundation for the rest of the mattress. This dense layer is followed by a zone transitioned layer that consists of different foam densities to not only offer more support where you need it but also relieve pressure.

This ensures that you have what you need where you need it. To top it off, Casper is sealed with an exquisite layer of high-density foam that gives you a good amount of cushioning without becoming too warm.

The foam contains a cooler layer on top of the memory foam layer which has an open-cell texture ensuring a free flow of air keeping you cool all through the night. The top layer acts as more of a latex foam which offers more of an adaptive feel.

Casper easily adapts to movements and the top cover is breathable, soft, and stretchy giving it a beautiful and comfy finish. Cocoon on the other hand has a simpler design compared to Casper. It consists of three layers; comfort top layer, transitional layer, and a base layer.

Having a simple design such as this means that the other materials used to complement the foam ought to be high quality to compliment the simplicity of the design. Having been in the business long enough, Sealy did a good job with the Cocoon.

The first layer is a 6-inch base dense foam layer that provides support from edge to edge of the mattress. This is then followed by a 2-inch layer of transitional foam tailored to withstand deep pressure avoiding the sinking sensation as you get some rest.

That ensures you do not feel the firm base layer which can be quite uncomfortable. Finally, Cocoons’ choice of the top layer is a memory foam tailored to adjust, conform, and contour to your shape as you sleep minimizing indentation and maximizing comfort.

  • Motion Transfer

One of the most uncomfortable things is to sleep on a mattress that leaves an indentation after you have switched positions. All foam-based mattresses have managed to solve this problem since the coil system inside the hybrid mattress tends to adapt quickly to motion. This does not mean that there is no movement created on the mattress, there is, only that it is subtler and quick ensuring maximum comfort of the sleeper.

Both Casper and Cocoon are exemplary at eliminating motion transfer. However, Cocoon does a better job in elimination motion transfer on the mattress because of the dense foam used on the mattress that stops motion and vibrations on its tracks.

Casper curbs motion transfer as a whole, hence you tend to notice some movement throughout the bed because of its adaptive nature of the mattresses’ top layer.

  • Temperature Control- Sleeping Cool

When it comes to comfortable sleep, extreme temperature can be a major hindrance so, how about a mattress that can curb that?

Nothing will beat a good night’s sleep than a neutral temperature sleeping environment. As much as many people would suggest that you get a hybrid mattress for temperature control, these foam mattresses have been designed to ensure that the sleeper stays as cool as possible.

The most important thing to consider when it comes to the cooling effect is adequate airflow. Casper uses an open-cell foam that provides for a free flow of air allowing any trapped heat out. The top cover is also lightweight and breathable. The top layer focuses on keeping the sleeper as cool as possible.

The Cocoon mattress tends to keep its sleeper’s neutral. The mattress tends to retain more heat than the Casper, however, the top cover uses a chill technology that ensures that there is a cooling effect. The thermic phase changing technology used on the cover pulls away the heat from the sleeper.

  • Casper and Cocoon mattress edge support

This is not a dominant selling point or where they shine. Both Casper and Cocoon do not have well-defined edge support or enhancements along their edges when you sit on the edge of the bed.


However, when you sleep on either you will notice that even as you slide close to the edge the mattress will still provide adequate support as far as the sleeping surface is concerned. It would be advisable to get an extra firm cocoon mattress in case you want that edgy extra edge support.

  • Delivery and Set-Up

Casper is one of the pioneer brands for this type of mattress which did pave way for other brands who produce this type of mattress. Other brands followed suit and embraced rampant advertising and low prices.

Sealy then launched Cocoon by Sealy and brought healthy competition to the online mattress ordering business. However, both brands have played a role in ensuring that foam mattresses are efficiently delivered to your doorstep at your convenience.

Once you have ordered, both mattresses arrive on your doorstep in a week. The unpacking and set up is similar. In both instances, you are advised to have a helping hand.

Casper; tends to have a stronger ‘newness’ smell compared to the Cocoon by Sealy. The difference in smell certainly comes from the mode and place of assembling which differs for both brands. Both brands use CertiPUR-US® certified foams hence, any smell of gas coming from the mattress during unpacking is safe and should fade in no time.

You can ventilate the room during unpacking in case you feel that that the gas is making you uncomfortable. It is highly recommended that you leave your newly set up mattress to firm up for a few hours in a well-ventilated room before making use of it. This applies to both Casper and Cocoon mattresses.

Cocoon by Sealy & Casper mattress – which wins?

If comfort, a luxury that all foam mattresses offer, and a good night’s sleep is your priority then one of these two is the ideal match for you. Regardless of their differences, each has its strengths.

Overall, both mattresses will do a great job providing the ideal feel and comfort of a foam mattress and you can never go wrong with either. If you are the kind of sleeper who seeks a cool night’s sleep as well as an adaptive sleeping solution, then your interest should lean towards getting yourself a Casper mattress.

If you also live in areas that experience extreme heat, you too should jump into the Casper bandwagon and do not look back. Are you all about experiencing different, cozy, and true memory foam with different options to choose from, then Cocoon by Sealy is your choice. Some of us like to be given a variety to choose from. Well, Sealy got you covered.
