Mattress Firmness

Do you know how a mattress feels? Firmness is all about that – how soft or hard it is. It’s important because it affects how comfortable a mattress is for different types of sleepers. The right firmness helps your spine stay aligned and gives extra support to sensitive areas of your body. That’s why the choice of firmness is crucial when purchasing a mattress.

The mattress industry uses a “firmness rating scale” that tells you how soft or firm the mattress is. Firmness is rated on a scale from 1 to 10, where 1 is soft, and 10 is really firm. If you want a soft mattress, you’d check out those rated around 1. But if you’re into something firmer, go for mattresses closer to 10 on that scale.

Let’s talk about how firm Cocoon Chill Mattress feels!

Firmness of Cocoon Chill Mattress

Many like a mattress that’s comfortable but not too hard. Both Chill Memory Foam and Hybrid Mattresses are medium-firm mattresses. They both score 6 out of 10 in firmness, so they’re just right for a wide range of sleepers. The Hybrid mattress is responsive and gives you better support around the edges.

Chill Memory Foam Mattress from Cocoon by Sealy might feel like you’re sinking in a bit, but don’t worry; you won’t get stuck. The bottom part helps with that. The support layer is 6 inches thick and is sturdy to support your body really well. It hugs your body and gives a sturdy base for good comfort.

Now, the Chill Hybrid? It’s a bit firmer. This mattress is a combination of memory foam and supportive coils. Those coils can move independently and give targeted support. It’s all about helping you sleep better through the night.

Material & Construction

Q1. What are the unique technology, design, and materials used in the construction of Cocoon Chill Mattress?

Cocoon Chill Memory Foam Mattress is made completely of foam. There’s a comfort memory foam layer on top, followed by a high-density base layer of foam.

Cocoon Chill Hybrid Mattress has the memory foam on top for comfort, but underneath, it’s got wrapped coils giving it some bounce. It’s like combining the softness of memory foam with the springiness of coils.

In this section of the mattress review, let us talk about the construction of the mattresses!

  1. Cover

Both Chill memory foam and Hybrid mattresses have this cool-to-touch cover. The cover is made of Phase Change Material. Basically, it’s a special fabric that absorbs your body heat and dissipates it. It is good, especially if you tend to get warm when you sleep!

  1. Foam Layer

This layer of Chill Memory Foam and Hybrid mattress features Sealy’s Perfect Fit Memory Foam. It’s a bit firmer and helps in airflow. It contours your body, gives a cozy feel, and promotes pressure relief.

  1. Comfort Layer 2

Under the Perfect Fit Memory Foam, there’s a Responsive Comfort Layer. It’s like a cushion that stops your partner’s movements from disturbing your sleep. It helps you sleep peacefully every single night!

The bottom layer of both Chill Memory Foam and Chill Hybrid Mattress from Cocoon by Sealy is unique. Let me break down what each layer does for you.

  1. Foundation Layer (Chill Memory Foam)

Cocoon Chill Memory mattress has a 6-inch thick memory foam base. This layer supports you while you sleep, keeps the mattress in shape, and acts as the mattress’s foundation. When you go from the comfort memory foam to this base layer, you’ll feel more supported, making the mattress feel firmer overall.

Foundation Coil Layer (Chill Hybrid)

At the bottom, Chill Hybrid mattress has a layer made of pocketed coils. There are 900+ of these coils; all wrapped up separately to let more air in and stop motion transfer.

The support layer of Cocoon Chill Hybrid has strong steel coils along the edges. This extra support around the edges is good, especially for couples who love to take up space on the mattress. It means you can spread out comfortably without feeling like you might roll off.

Overall Rating 3.71/5



Q1. How would you rate Cocoon Chill Mattress from a repositioning & responsiveness perspective?

Repositioning is when you switch your sleep positions during the night. Responsiveness, on the other hand, is all about how well your mattress molds to your body and aligns with your changing positions and movements. A mattress that’s responsive bounces back into shape faster, so it’s easier for you to change positions while you sleep.

Chill mattress from Cocoon by Sealy is a responsive foam mattress. It’s got a high-density support core and a firm transition layer, so you won’t sink in too much. Cocoon Chill Hybrid is pretty easy to move on due to its coiled support. It’s not as stiff as other hybrid mattresses, making it easier to switch positions. This mattress feels medium firm and has coils that help you move without feeling stuck.

Even though the memory foam parts hug your body and take a bit longer to adjust, the coils balance it out by being springy. And since it’s not too soft, you won’t sink in too much when you lie down.

Comfort, Back Support, Pressure Relief


Q2. How would you rate Cocoon Chill Mattress for providing comfort and pressure relief to sleepers?

The comfort layers of Cocoon Chill mattress hug your body just right, giving relief from pressure points. It keeps your spine in a good position, and the memory foam layer helps ease pressure on your hips and shoulders by spreading out your weight.

Perfect Fit memory foam comes in both hybrid and memory foam mattresses. It quickly adjusts to your body shape, giving you great support and a comfy feel. This special foam is made to ease pressure points and boost your overall comfort.

Cooling & Temperature Control


Q3. How would you rate the cooling and overall temperature control characteristics of the Cocoon Chill Mattress?

Memory foam mattresses can get pretty warm because they hug your body closely and as a result hold onto your body heat. However, Cocoon Chill Memory Foam mattress tackles this problem with its heat dissipating features. It’s actually cooler to sleep on compared to other mattresses that are all foam.

The mattress cover for both the foam and hybrid versions is made from Phase Change material. It helps keep your body from getting too hot by pulling heat away. Plus, Cocoon Chill Hybrid has coils inside that let air move around. If you tend to get hot while sleeping, these features might make a big difference in helping you stay cool all night long.

Motion Isolation and Sharing a Bed


Q4. Does Cocoon Chill Mattress provide reasonable motion isolation when sharing a bed with others?

Cocoon Chill Memory Foam and Hybrid Mattress help in motion isolation. The Responsive Comfort layers contour to your body and keep movements from getting transferred across the bed. The Hybrid mattress has coils that add a bit of bounce, which might cause some movement. But don’t worry; those coils are individually wrapped up on to keep movements from getting transferred.

Edge Support


Q5. How would you rate the edge support of Cocoon Chill Mattress?

Foam mattresses usually aren’t strong on the sides. Cocoon Chill Memory Foam has dense foam in the middle, but the edges might sag a bit. If you really need a solid edge to help you get out of bed easily, you might prefer the Hybrid Mattress.

Cocoon Chill Hybrid has coils that go all around the mattress, making it feel strong and steady. You can sit or sleep near the edge without worrying about sinking too much or sliding off.

Recommendation based on sleeping style

How you sleep can really make a difference in how well you rest at night. It’s important to find the best way to sleep to keep your whole body feeling good.

There are three main sleeping positions: side, back, and stomach sleeping. Each has its own advantages and disadvantages. Choosing the right one for you can really change how you feel when you wake up in the morning!

In this part of our mattress review, let’s discuss how The Chill mattress from Cocoon by Sealy works for different sleep positions.

Cocoon Chill Mattress and Side Sleepers

If you’re a side sleeper, you’d probably love a mattress that hugs your body just right while giving good support. Cocoon Chill Memory Foam does exactly that. Its memory foam layer molds to your shape and eases those pressure points, while the supportive layers keep you from sinking too much.

If you weigh more than 130 pounds, this mattress might be suitable for you. It strikes a good balance between comfort and support for side sleepers. But if you’re under 130 pounds, you might feel a bit more pressure around your hips and shoulders because you won’t sink in as much.

Now, Cocoon Chill Hybrid, with its medium firmness, is good for side sleepers under 230 pounds. It lets you sink in just enough to relieve pressure and keep your spine aligned. Even if you’re over 230 pounds, it’ll help with pressure points, but some might find it a bit tough to keep their spines properly aligned.

Cocoon Chill Mattress and Back Sleepers

Cocoon Chill memory foam mattress is good for people who sleep on their backs. It has medium level firmness and helps keep your back in a good position while you sleep. If you weigh between 130 and 230 pounds, this mattress works really well for you. But if you’re under 130 pounds, you might not feel as snug, and if you’re over 230 pounds, your hips might sink in a bit.

Cocoon Chill Hybrid mattress features memory foam that hugs your body and keeps your hips comfy if you sleep on your back. It also has coils to make sure you stay supportive all night long.

These mattresses are medium firm, which means if you’re under 230 pounds, they would keep your spine in line. But if you weigh more than 230 pounds, your hips might sink in too much and cause some pressure on your lower back.

Cocoon Chill Mattress and Stomach Sleepers

If you are a stomach sleeper, Cocoon Chill Memory Foam and Hybrid mattresses can effectively support you all night. It stays firm enough to keep you comfortable without sinking too much in the middle. Plus, its memory foam layer adds a bit of softness.

Cocoon Chill Hybrid is also good for stomach sleepers. Its memory foam layers and individually-wrapped coils make the bed comfortable and supportive at the same time.

If you weigh less than 230 pounds, this mattress should give you a nice combination of softness and support. If you’re under 130 pounds, your spine should stay aligned well, but the mattress might feel a bit too firm. For those over 230 pounds, you might sink in more around your hips and stomach, making it harder to keep your spine aligned.

Customer Policy

Trial & Return

Why do mattress manufacture’s offer free trial period for online purchase of mattresses?

Whether you purchase a mattress in a store or online, you make a long-term decision that could impact your sleep health. When you buy a mattress in a store after lying on a few mattresses, listening to sales pitches, and getting some great deals, you ignore how you and your partner's body will react to the mattress. Any new mattress has a break-in period (adjustment period), and your body needs time to adjust to a better feel. Lying on a mattress for a short time in a store setting does not provide insight. Buying a mattress online further compounds the fact that you never got to touch or feel the mattress before you purchase. That's why mattress manufacturers offer an extended trial period to try the mattress in a comfortable home setting without any pressure and then make the call whether to retain or return.

What is the duration of Cocoon By Sealy’s risk-free trial period?

Cocoon by Sealy offers a 100-night sleep trial period starting from the delivery date.

What does Cocoon By Sealy’s warranty covers in terms of defects?
