Cocoon Chill Memory Foam Mattress

The Cocoon Chill mattress is medium-firm. It may suit people who want to reduce pressure points and prefer comfort over firmness.

The top layer consists of memory foam that adapts to the individual’s body shape and sleeping position. Below this, a layer of comfort foam helps prevent motion transfer. The bottom layer uses the hardest foam, providing support.

Cocoon have designed the cover of the mattress to keep the sleeper cool, using a proprietary “Phase Change Material” to absorb and dissipate heat.

Cocoon Chill Hybrid Mattress

This medium-firm mattress combines foam with a supportive innerspring base.

The upper memory foam layer adapts to body shape and position, allowing the mattress to reduce pressure points and cushion the body.

Each coil in the layers beneath the foam moves independently. The company use this feature to provide additional support and reduce motion transfer more than a standard innerspring mattress does.

They also use the cooling cover with Phase Change Material on their hybrid mattresses to help keep the sleeper cool.

This option may suit people who need more support, including edge support, such as those who are switching from a standard innerspring to a hybrid mattress.

The range of Casper mattresses includes both foam and hybrid options:

Casper Original Mattress

This mattress provides a combination of support and comfort to suit all sleep preferences. People can choose between an all-foam mattress and a hybrid option.

The upper layer of foam — a perforated foam designed to absorb and release heat from the body — uses the company’s “Airscape” technology.

Below this, a “Zoned Support” layer uses three areas of varying foam densities to provide targeted support. Softer foam near the shoulders provides more relief to the upper body, while firmer foam under the hips helps align the spine.

Beneath this, a layer of dense foam provides structure and support. In the hybrid version, this layer includes pocketed coil springs for added support.

People choosing between Cocoon and Casper may wish to consider the following factors when deciding what mattress to purchase:

  • Feel: Cocoon mattresses have fewer plush options than Casper. The Casper Nova Hybrid offers highly plush comfort.
  • Support: Both Casper and Cocoon offer mattresses with good firmness and support levels, with the hybrid options adding even more support.
  • Cooling: Cocoon mattresses have an active cooling layer, which may make them better for people who tend to get hot during sleep. Casper use a variety of cooling technologies across their mattress range.
  • Price: Cocoon mattresses generally have a lower price point than Casper mattresses with comparable features. However, many of the higher price Casper mattresses have more features.

Sustainability

Sustainability is an important factor for many sleepers. Both Cocoon and Casper mattress are CertiPUR-US-certified. This certification means that a mattress has low volatile organic compound (VOC) emissions and does not contain:

  • ozone depleters
  • formaldehyde
  • heavy metals, such as lead and mercury
  • regulated phthalates

When replacing a mattress, it is important to consider how to dispose of a used mattress responsibly. Learn about recycling a mattress here.

Sleep is an important factor in overall health. The Centers for Disease Control and Prevention (CDC) note that adults need at least 7 hours of sleep each night. Regularly getting too little sleep may increase the risk of conditions such as heart disease, high blood pressure, and diabetes.

Research in the Journal of Chiropractic Medicine notes that good sleep quality plays a role in overall well-being by:

  • reducing fatigue
  • maintaining a normal circadian rhythm
  • improving physical regeneration

One review found that medium-firm or self-adjusted mattresses may best promote sleep quality and reduce pain.

Cocoon and Casper both offer bed-in-a-box mattresses. Casper’s mattress range includes a wider variety of features and options to meet different needs. Cocoon offer a more standardized approach but have a lower price point.

A person’s health needs, budget, and support and comfort preferences are likely to be the factors that contribute most to their mattress choice.
