Who Should Choose the Cocoon Mattress?

  • Hot sleepers who like the feel of memory foam. While this is an all-foam mattress, Phase Change Material in the cover can help regulate body temperature for cooler sleep.
  • Average-weight back and side sleepers. The all-foam construction accommodates back and side sleepers in the average weight range nicely.
  • Shoppers on a budget. Looking to save money but still sleep comfortably? This is a good pick.

Who Should Choose the Nectar Mattress?

  • Sleepers looking to alleviate body aches. If you’re dealing with joint or hip pain, this medium-firm mattress has the pressure relief you need.
  • Couples looking for great motion isolation. The cushioning memory foam means minimal motion transfer if you share your bed.
  • Combination. It’s a firmer mattress, so it’ll accommodate people who move around in their sleep.

Cocoon vs. Nectar: Top Similarities 

  • Mattress type: Both mattresses are constructed with layers of foam only – no innerspring coils.
  • Value: Both mattresses offer good value for the money, though you will spend a little more on the Nectar.
  • Bed-in-a-box: Both mattresses are compressed, rolled, and shipped to your door in a box.

Cocoon vs. Nectar: Top Differences 

  • Mattress firmness: While both mattresses have a medium firmness, the Cocoon Chill is on the softer side, while the Nectar is firmer.
  • Cooling features: The Nectar has a gel-infused layer, while the Cocoon Chill has Phase Change Material in the cover.
  • Sleep positions: The Nectar is better suited to combination sleepers because of its firmer feel, while the Cocoon Chill works well for side and back sleepers under 230 pounds.

Cocoon vs. Nectar: Firmness & Feel Differences

The Cocoon and the Nectar are both considered medium-firm mattresses, but they fall on different sides of the scale.

What’s the Firmness Of the Cocoon vs. Nectar Mattresses? 

The Cocoon Chill is a 5 on the 10-scale (10 being firmest), which means it’s medium-soft. Average and lightweight sleepers will find it soft and doughy, but it may be too squishy and lacking in support for heavier sleepers.

The Nectar mattress is a medium-firm mattress – a 6 out of 10 on the firmness scale. It offers lightweight and average sleepers a hugging sensation, without feeling trapped. Heavyweight sleepers, however, may find themselves sinking too deeply into the mattress.

What Do the Cocoon vs. Nectar Mattresses Feel Like?

The Cocoon Chill mattress has a soft, contouring feel. When you lie down, it molds to your shape with minimal bounce. The Nectar mattress is a little firmer – you feel like you’re being hugged but you’re a little more elevated instead of cradled.

What’s It Like to Sleep On the Cocoon vs. Nectar Mattresses?

Side sleepers will find the cushioning and pressure relief they need on the Cocoon by Sealy, but stomach sleepers will likely find it lacks the support they need for proper alignment. Back sleepers, however, should find the mattress maintains the curve of their back nicely. Combination sleepers will likely do better on a firmer mattress that makes it easier to move around.

On the Nectar, back and side sleepers will find themselves supported comfortably. Combination sleepers should also fare well, though stomach sleepers in heavier weight ranges may need to consider a hybrid mattress for more support in the hips.

The Cocoon vs. Nectar Mattresses By Body Type

Cocoon Performance By Body Type & Sleeping Position:

Lightweight (< 130 lbs): 535
Average-weight (130–230 lbs):425
Heavyweight (> 230 lbs): 313

Nectar Performance By Body Type & Sleeping Position:

Lightweight (< 130 lbs): 433
Average-weight (130–230 lbs):425
Heavyweight (> 230 lbs): 223

1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent

Average-Weight Sleepers (130–230 lbs)

Average-weight back and side sleepers will likely find the Cocoon has the support and pressure relief they need for comfortable sleep. Stomach and combination sleepers will likely find it too soft to properly elevate the hips and make it easy to switch positions.

The Nectar mattress will also work well for average-weight back and side sleepers. It’s firm enough that combination sleepers can move easily, but stomach sleepers should consider a more supportive mattress.

Heavyweight Sleepers (> 230 lbs)

Heavyweight back sleepers should find the Cocoon Chill supportive, but it may veer too soft. Side sleepers with heavier weight may find themselves sinking too deeply for adequate pressure relief, and stomach sleepers may also find this doesn’t have the firmness and support to keep the hips elevated. That makes this a poor choice for heavyweight combination sleepers too.

The Nectar mattress may not support heavyweight back or stomach sleepers adequately enough either. But most heavyweight side sleepers should find the contouring layers work well for spinal alignment and pressure point relief. Combination sleepers in this weight range will probably do better with a mattress designed to support higher body weights.

Lightweight Sleepers (< 130 lbs)

Lightweight back and side sleepers will find the Cocoon Chill a great mattress. Stomach sleepers in this weight range who like a soft feel should also feel supported, but lightweight combination sleepers will likely find it too soft to move around comfortably.

The Nectar is a great pick for lightweight back and stomach sleepers, but side sleepers in this weight range may not sink in enough to benefit from the pressure-relieving benefits. Lightweight combination sleepers who primarily move from stomach to back should find the Nectar works well, but if you spend a lot of time on your side, there are better options.

Differences In Mattress Construction 

The 10-inch Cocoon Chill has three layers of foam for comfort and support. The Nectar is a 12-inch mattress with three layers of foam.

Cocoon Mattress Materials Nectar Mattress Materials
Cooling cover with Phase Change MaterialQuilted memory foam cover
Memory foam layerMemory foam comfort layer
Responsive foam comfort layerAdaptive memory foam support layer
Dense foam support layerFoam base layer


The Cocoon Chill uses what it calls Phase Change Material in the cover, which is intended to draw away body heat. The Nectar mattress is wrapped in a quilted poly-blend memory foam cover that’s breathable and soft to the touch.

Comfort Layers

The Cocoon Chill has two comfort layers – a “Perfect Fit Memory Foam” layer that adapts to your shape over a responsive foam layer that minimizes motion transfer. The comfort layer on the Nectar is memory foam that’s been infused with cooling gel to help neutralize body heat.

Support Layers

The support layer on the Cocoon Chill is its base layer – thick and dense for resilience and durability. On the Nectar, adaptive memory foam in the base layer makes it responsive, while a thick base layer offers stability and edge support.

Cocoon vs. Nectar Mattress Performance Ratings & Differences


It’s called the Cocoon “Chill,” and the Phase Change Material can help regulate body heat. But that’s the only cooling feature, and it should be said – there are better mattresses out there if that’s a big consideration. The Nectar mattress uses cooling gel, which neutralizes body heat to some extent. Still, it does get warm.

Motion Transfer

The Cocoon Chill isn’t a great choice for motion isolation, despite being foam. The Nectar, however, absorbs motion well, so it’s a good pick for couples.

Edge Support 

The Cocoon mattress came up short here too. All-foam beds tend to lack decent edge support, and the Cocoon is no exception. While the Nectar is an all-foam mattress, its edge support is much better. You’ll sink a bit if you’re sitting on the edge, but you probably won’t slide off.

Pressure Relief 

Both mattresses should offer adequate pressure relief for average-weight sleepers, but lightweight and heavyweight sleepers may find themselves too high or too deep in the Nectar mattress to be comfortable.

Pain Relief 

Sleepers with back pain in light to average weight ranges will find the Cocoon a good option, but heavier sleepers should look for mattresses with more support. The Nectar is a good pick for shoulder or hip pain, but lacks the firmness necessary to alleviate back pain.


The softer foam in the Cocoon Chill means below-average durability. Fortunately, Sealy offers a 10-year warranty that covers sagging. The Nectar has better durability and should stay supportive for sleepers under 230 pounds for 6 to 7 years.

Shipping, Returns, & Warranties 


The Cocoon Chill mattress ships free via UPS Ground in the U.S. It has a 100-day trial window and a 10-year limited warranty.


The Nectar mattress also ships free in the contiguous U.S. It has a generous 365-night sleep trial and a lifetime warranty with the Nectar Forever warranty.

Other Models Available

Our Final Take

Both all-foam mattresses will show up on your doorstep and offer reasonable pressure relief for average-weight sleepers. But the Cocoon Chill is definitely a softer pick, so stomach sleepers or heavier people may find it lacks support. While the Cocoon is a better budget buy, the Nectar will probably accommodate combination sleepers better.

Cocoon vs. Nectar FAQs

Is the Cocoon Chill worth it?

It’s a great value mattress for lightweight and average-weight side and back sleepers. Those who love the feel of memory foam but worry about overheating will also find the Cocoon Chill a good mattress for the money. Combination sleepers should look for a firmer mattress, however.

What are the cons of a Nectar mattress?

The Nectar mattress may not be supportive enough to heavyweight sleepers. Some customers have also experienced lengthy shipping delays and find customer service disappointing, with long chat wait times and unanswered calls and emails. That can be a problem if you run into any issues with your mattress.

How long does the Cocoon mattress last?

The soft foam in the Cocoon mattress will break down faster than latex or coils, so you shouldn’t expect it to last longer than ten years.  But if the mattress sags while under its 10-year warranty, you should be able to get it repaired or replaced.
