Cocoon Chill Memory Foam Mattress

The Cocoon Chill Memory Foam Mattress is a supportive and comfortable option.

It utilizes layers of foam in varying densities to provide comfort and support and prevent motion transfer. The mattress may suit side sleepers or back sleepers who need pressure relief and comfort.

Memory foam mattresses have a reputation for being warm. Cocoon mattresses include a top layer of patented “phase change technology” designed to move body heat away from the body and keep the mattress feeling cool. This may help prevent some sleepers from overheating when using the mattress.

Cocoon Chill Hybrid Mattress

The Cocoon Chill Hybrid Mattress utilizes the same technology and foam as the standard foam mattress, but it also includes coils.

The layer of individually pocketed coils sits at the bottom, and the edge of the mattress is reinforced with steel. These features help provide structure and support.

This choice of mattress may suit people who need more support and those who prefer the sturdy feeling of a standard innerspring mattress.

Purple offer a few different mattress options, all utilizing their patented Purple grid technology.

The Purple grid technology is an elastic polymer gel that responds to the sleeper’s body, weight, and position. Purple claim that this can provide comfort and pressure relief.

The Purple website notes that the Purple grid features more than 1,800 air channels to help move air away from the body and prevent overheating.

All their mattresses are medium firm.

Purple Mattress

The original Purple Mattress uses multiple foam layers, together with the patented Purple grid, to provide comfort and support.

It is designed for all types of sleeper but may specifically suit those who need pressure relief and comfort.

Purple Hybrid Mattress

The Purple Hybrid Mattress combines the patented gel grid with the support of individual support coils.

Individually wrapped stainless steel coils give the hybrid model a more supportive feel.

Purple Hybrid Premier Mattress

This mattress is available in different thickness options. Users can choose either 3 or 4 inches (in) of material, with larger thicknesses providing a more weightless feeling.

Beneath this grid sit the supportive coils, which offer a more responsive feeling from the mattress.

This is a high comfort option. It may suit couples with different sleep needs or people with more body weight who need more comfort and relief from a mattress.

There are a few factors to consider when choosing a mattress. These include:


Support and firmness are two important factors for any mattress. Some people may need the added support and edge support that comes from a hybrid mattress, compared with foam mattresses. Both Purple and Cocoon offer hybrid mattresses with this extra support.

Purple’s unique grid technology gives their mattresses a unique feel and support system. Cocoon mattresses provide a more standard memory foam support and feel.

Motion isolation

Motion isolation may be important for people who move in the night and do not want to wake themselves, or a partner, up.

Both Cocoon and Purple mattresses should help isolate motion. For people who are more sensitive to these movements, Purple offer a very plush 4-in grid that may help with motion isolation.

Temperature regulation

Temperature regulation refers to how well a mattress can help manage the temperature near the body. Foam-style mattresses tend to absorb more heat and may cause overheating, so mattress manufacturers find ways to regulate this effect.

For example, Cocoon mattresses use a patented cover that moves heat away from the body. Likewise, the gel grid from Purple contains many channels that move air away from the body.


Both Cocoon and Purple mattresses use CertiPUR-US certified foam. This means that they are free from:

  • compounds that deplete ozone
  • formaldehyde
  • lead, mercury, or other heavy metals
  • regulated phthalates
  • volatile organic compounds

Also, Purple’s patented hyper elastic polymer is made from food- and food contact-grade ingredients.

When purchasing a new mattress, it is also important to consider how to dispose of an old one responsibly.

Most adults need at least 7 hours of sleep each night, according to the Centers for Disease Control and Prevention (CDC). People who regularly get less sleep than necessary may be at a greater risk of heart disease, diabetes, and high blood pressure, among other issues.

There are many things that a person can do to improve their sleep quality and overall sleep health. One of these things is to ensure that they are sleeping on the right mattress for their unique needs and preferences.

One survey found links between sleeping on a comfortable mattress and having better sleep quality. People who had less comfortable mattresses stayed in bed for just as long but had worse sleep quality.

Good sleep quality is important for overall health. Research in the Journal of Chiropractic Medicine notes that good sleep quality helps reduce fatigue and improve physical regeneration.

What makes a mattress comfortable will vary from person to person, and self-rated comfort levels may be most important.

Research notes that mattresses subjectively rated as medium firm or custom-inflated may promote sleep quality and improve spinal alignment.

Cocoon and Purple offer similar products and services.

Cocoon offer memory foam and hybrid options, with a cooling topper to help prevent overheating. Purple use patented gel technology, providing a unique feel.

Their mattresses have similar firmness levels and ratings but use different materials. The other major differences between these brands may be in their subjective comfort and price differences.
