I’m Chris Miller. Cocoon shows up constantly in “cooling mattress” searches, usually positioned as a more affordable option. For this review, I focused on the two core models in the Chill Collection—the Chill Memory Foam and the Chill Hybrid—to see how they actually feel night to night and where the trade-offs show up.
For this Cocoon review, I worked with a small in-house testing group. Marcus stressed support and edge stability, Jenna focused on cooling comfort, and Ethan handled couple testing and motion transfer. We combined notes so the differences between the two models came through clearly.
We kept the setup consistent. Each mattress was tested in the same room with the same bedding, and we rotated through back, side, and stomach sleeping. Along the way, we logged temperature feel, pressure build-up, ease of movement, edge stability, and partner disturbance using repeatable checks.

Product Overview
| Mattress | Pros | Cons | Ideal For | Price (Queen, typical) | Overall Score |
| Cocoon Chill Memory Foam | Cool-to-the-touch cover, close contouring, excellent motion isolation, frequent promotions | Edges are only average, bounce is limited, heavier stomach sleepers may want more lift | Average-weight side and back sleepers, hot sleepers who want all-foam feel, motion-sensitive couples | Pricing varies by size and promotion | 4.3 / 5 |
| Cocoon Chill Hybrid | More lift and bounce, steadier edges, strong airflow, balanced medium-firm feel | Transfers more movement than the all-foam model, can feel firm for very light side sleepers | Mixed-position sleepers, hot sleepers needing extra support, couples using the full surface | Pricing varies by size and promotion | 4.4 / 5 |
Testing Team Takeaways
The biggest split between these two Cocoon models is feel. The Chill Memory Foam is quieter and more “hugging,” and it does an excellent job muting partner movement. The Chill Hybrid feels more buoyant, holds the edges up better, and is easier to change positions on—especially if you don’t like the slow-sink sensation of all-foam beds.
Marcus pushed both beds for deeper support. On the all-foam model, he liked the pressure relief but noticed more sink when he stayed on his stomach. The hybrid felt more “held up” through the midsection and stayed steadier when sitting on the edge.
Jenna paid the closest attention to cooling comfort. She preferred the first-touch cool feel on both models, but she liked the hybrid better on warmer nights because it didn’t trap as much heat once you settled in.
Ethan focused on movement and couple testing. The memory-foam model did the best job dampening motion. The hybrid still performed well, but the springier core made big movements more noticeable.
Cocoon Mattress Comparison Chart
| Mattress | Type | Firmness (1 soft–10 firm) | Thickness | Key Materials | Cooling Performance | Support Character | Pressure Relief | Responsiveness | Motion Isolation | Durability | Edge Support |
| Cocoon Chill Memory Foam | All-foam | Around 6–6.5 (medium-firm) | 10 inches | Cooling cover + “Perfect Fit” memory foam (all-foam build) | Cool on contact; generally temperature-neutral for most sleepers | Best for average-weight back and side sleepers; less supportive for heavier stomach sleeping | Strong contouring at shoulders/hips; good for pressure points | Moderate; rolls are easy, but it’s not springy | Excellent; absorbs most partner movement | Solid for the price class with simple foam stack | Fair; usable, but compresses when sitting |
| Cocoon Chill Hybrid | Hybrid | Around 6 (medium-firm) | 12 inches | Cooling cover + memory foam over pocketed coils | Very good airflow; typically sleeps cooler than the all-foam model | More lift and easier movement; supports a wider range of body types | Good pressure relief with a shallower hug | High; springier surface and quicker rebound | Good; slightly more motion transfer than all-foam | Coil core helps resist sag under heavier loads | Good; edges feel sturdier for sitting and sleeping near the side |
What We Tested and How We Tested It
We scored both Cocoon models using the same hands-on process we apply across our mattress reviews. Ratings reflect real nights of sleep plus repeatable checks for support, pressure relief, cooling, motion isolation, responsiveness, and edge stability, and firmness.
Support focused on spinal alignment in back and stomach sleeping. We watched for sagging through the hips and whether the shoulders stayed supported instead of dipping.
Pressure relief came from side-sleeping checks, plus targeted time on the shoulder and hip. We noted how quickly the surface filled in around pressure points and whether any numbness showed up after a full night.
Cooling combined a few things: the first-touch feel of the cover, how warm the foam felt after an hour, and whether heat built up enough to cause position changes. We also paid attention to airflow differences between the foam and hybrid cores.
Motion isolation was scored with a standard couple-movement sequence (getting in/out, changing positions, and turning). Edge support measured both sitting stability and how secure the perimeter felt when sleeping near the side.
Responsiveness covered how quickly the mattress regained shape after we moved and how much effort it took to roll, pivot, and get up. The goal was to capture “real” ease of movement, not just bounce.

Cocoon Mattress: Our Testing Experience
Cocoon Chill Memory Foam
Our Testing Experience
We started with the Chill Memory Foam because it’s the simpler build and the one most people land on first. The surface has that cool-to-the-touch sensation right away, and the foam underneath leans into a gentle, pressure-relieving cradle rather than a springy feel.
On my back and side, the mattress kept my spine fairly level while still letting my shoulders sink in. It’s not a marshmallow-soft bed, but it does “fill in” around the hips and ribs in a way that makes pressure points feel less sharp by morning.
Marcus (around 230 pounds) was more divided. He liked the quiet, cushioned feel, but on his stomach he noticed deeper sink through the midsection. For heavier stomach sleepers, the support can feel less steady than a coil-based hybrid.
For couple testing, the Chill Memory Foam was the stronger performer. Larger movements were muted quickly, and smaller shifts didn’t ripple across the surface the way they do on springier beds.
The main compromise is the perimeter. Sitting to put on shoes compressed the edge more than we’d call “strong,” and sleeping right up against the side felt less secure than on the hybrid.
Overall, this model makes the most sense for average-weight back and side sleepers who want cooling plus classic memory-foam contouring—and who don’t need the firmest edges.
Pros & Cons
| Pros | Cons |
| Cooling cover feels cool at first touch | Edge support is only average for sitting |
| Excellent motion isolation for couples | Limited bounce if you prefer a springy feel |
| Comfortable contouring for pressure points | Heavier stomach sleepers may want more lift |
| Aggressive sale pricing gives high value for cooling-focused shoppers | Long-term durability sits in “good” rather than ultra-premium territory |

Cocoon Chill Hybrid
Our Testing Experience
The Chill Hybrid keeps the same cooling cover on top, but the feel is immediately different once you lie down. You get less slow-sink and more buoyant support, with the coil layer adding lift as you change positions.
On my back, it stayed flatter through the hips than the all-foam model, which made it easier to relax without feeling “stuck.” Side sleeping still had enough cushioning for shoulders, but the hug is shallower than on the foam version.
Marcus preferred the hybrid. Under heavier load, the coil core kept the midsection from dipping as much, and he felt more stable when sleeping closer to the edge.
Cooling was strong, especially later in the night. The hybrid didn’t hang on to heat the way many all-foam beds can, and airflow through the coil unit made the surface feel more consistent.
Motion isolation was still good, but you do feel more movement than on the memory-foam model—most noticeable with bigger shifts like getting out of bed.
If you want a cooler feel plus easier movement and sturdier edges, the Chill Hybrid is the more well-rounded pick. It’s also the safer bet for combination sleepers and heavier bodies.
Pros & Cons
| Pros | Cons |
| Buoyant feel; easier to move around | More motion transfer than the all-foam model |
| Better edge stability for sitting and sleeping near the side | Can feel firm for very light side sleepers |
| Strong airflow for hot sleepers | Less deep hug if you love classic memory foam |
| Responsive surface helps restless sleepers change positions easily | Price sits above the foam Chill, though still budget-friendly for a hybrid |

Across our scoring, the all-foam model wins on motion isolation and that classic memory-foam contouring. The hybrid scores higher for edge support, ease of movement, and airflow—making it the better “one mattress for most people” choice if you’re unsure between the two.
Best Picks
- Best Cocoon Mattress for Hot Sleepers on a Budget: Cocoon Chill Memory Foam. If you like classic memory foam contouring and want a cool-to-the-touch cover, this is the value choice in the line.
- Best Cocoon Mattress for Heavy and Combo Sleepers: Cocoon Chill Hybrid. The hybrid core adds lift, stronger edges, and better airflow for cooling—helpful if you move a lot or need sturdier support.
- Best Cocoon Mattress for Motion-Sensitive Couples: Cocoon Chill Memory Foam. The all-foam build isolates movement better. If you’re shopping for Couples, that low motion transfer is the main advantage.
How to Choose the Cocoon Mattress?
Choosing between the two Cocoon models mostly comes down to feel and body type. If you like a deeper memory-foam cradle and want the quietest motion control, start with the Chill Memory Foam. If you want more lift and easier movement, the Chill Hybrid is the safer default.
If you’re a hot sleeper, the hybrid generally stays more even later in the night thanks to the coil airflow. The all-foam model still offers a cool first touch, but it can feel warmer for people who retain heat in foam.
For a guest room, the all-foam model is a straightforward choice because it’s quiet and easy to live with. If the bed will see nightly use—or higher body weight—the hybrid’s coil support is the safer long-term bet.
If you’re a lighter side sleeper, pay attention to how the mattress treats your shoulders and hips—the foam model tends to feel more forgiving there. A back sleeper who wants a flatter, more lifted feel will usually like the hybrid better.

Limitations
Cocoon keeps the lineup simple, which also means fewer niche options. Both models sit around a medium-firm feel, so shoppers looking for an ultra-plush or extra-firm mattress won’t find a true match here.
The all-foam model also isn’t designed to feel “springy,” and its edges are more flexible than many hybrids. If you want a very responsive, traditional innerspring feel—or you rely heavily on a firm perimeter—the hybrid is the better fit in this line.

FAQs
How many Cocoon mattress models are there right now?
Cocoon’s Chill Collection is centered on two options: the Chill Memory Foam and the Chill Hybrid.
Is the Cocoon Chill Memory Foam good for side sleepers?
For many average-weight side sleepers, yes—the foam contours well at the shoulder and hip. If you’re very light, it may feel a bit firm; if you’re heavier, you may prefer the hybrid’s extra lift.
Who should pick the Cocoon Chill Hybrid instead?
Choose the hybrid if you want easier movement, stronger edges, and a more buoyant feel—especially if you’re a combination sleeper or carry more body weight.

How cool do Cocoon mattresses actually sleep?
Both models start cool to the touch thanks to the cover. Over a full night, the hybrid usually stays more temperature-neutral because the coil layer lets more air move through the mattress.
Related: The 10 Best Cooling Mattresses
How do Cocoon mattresses perform for couples?
The all-foam model isolates motion best and keeps the surface quieter. The hybrid still does well, but the springier core makes larger movements easier to notice.

Are Cocoon mattresses supportive enough for stomach sleepers?
For lighter-to-average stomach sleepers, either model can work at a medium-firm feel. Heavier stomach sleepers generally do better on the hybrid, which holds the midsection up more evenly.
What about edge support on Cocoon mattresses?
The hybrid has the stronger perimeter for sitting and sleeping near the side. The all-foam model is usable, but you’ll feel more compression at the edge.
