Cocoon Bed: are Baby Sleep Positioners Safe?



We know that a healthy newborn sleeps up to 20 hours a day and requires a bed where they will feel comfy and safe. That why it’s so important to choose an appropriate bed for your baby and a cocoon bed is one option to consider. Let’s talk about the advantages and disadvantages of this bed.



The original idea of the ergonomic cocoon bed belongs to Daniel Saldutti, a French kinesiologist who specializes in pediatric research and works together with pediatricians to make the dream of an ideal bed for premature babies come true. After long-term observations and tries, the cocoon bed was developed and brought to many hospitals in France for a probation period.  It got really good reviews and was recommended not only for premature babies but for full-term babies too. It was prepared in three different categories. The first two are used only in clinical settings.



  • ·      S1– primarily for premature babies with a weight of more than 1200 gr (for use in hospitals)


  • ·      S2- mainly for premature and full-term babies with a weight of more than 2 kg. This model is also for hospital use.


  • ·      S3– the most popular model which can be used at home for babies with a weight of more than 2800 kg


There are cocoons that are approved for use until 8 months of age.



This type of bed initially became popular, especially in European countries, because parents noticed that their child felt comfy and protected when placed in a cocoon. They fell asleep faster and slept more soundly. The semi-fetal position soothes and reassures him. It helps limit the onset of problems that could affect him during the first few months, like colic, and encourages physical development. Manufacturers state that their product helps to reduce Moro reflex, limits reflux problems, minimizes the risk of flathead, and improves the visual-motor coordination of the baby.




you have to pay special attention to the period of time when a baby starts to roll over because your presence is necessary to avoid any sort of accident to do with the cocoon bed.



Some details about the cocoon mattress:


  • ·     It has a pear shape with a dip that helps the baby curl up.
  • ·      The incline of the bed is 20 degrees, which helps the baby see more than just the ceiling and helps them develop coordination.
  • ·      The material used for this bed is penopolyurethane, which has a specific density and hardness that helps avoid flat head syndrome, or plagiocephaly.
  • ·      The mattress has a special adjusted roll for legs that help keep the body in the right position. It is beneficial for digestion.




There are also disadvantages to the cocoon beds.


  • ·      Some parents noted that during the summer their babies became hot very easily because of the material that is used for the bed.
  • ·      This type of bed doesn’t have protective borders, just a security belt



There are a few companies on the market that specialize in this type of bed. Among them are French companies Red Castle and Babymoov, and Swedish companies Babynest and Sleepyhead (Docatot).


The US brand Woombie stopped producing cocoon beds due to FDA regulations. Parents were warned that sleep positioners such as cocoon beds can be a cause of suffocation and are considered dangerous to use. The FDA reminds parents about the recommendations of the American Academy of Pediatrics to position babies on a firm and empty surface for sleep. This surface should not contain any loose bedding, toys, or pillows. The FDA states that cocoon beds, as well as other types of sleep positioners, are not safe and also what led to a few numbers of deaths among infants in past years. Hence, you, as a parent, have to think twice before buying the cocoon sleep positioner, which is still available on Amazon, Ebay, etc.






At the same time, going through the official reports of European authorities, as well as through the reviews of many satisfied and happy parents, we found that there were no confirmed deaths of infants in Europe related to the use of cocoon beds. And if you read the instructions for cocoon beds, you will see that the manufacturers warn parents that they cannot leave the baby unattended in this bed.



We informed you about all the risks associated with the sleep positioners and about the pros and cons of this type of product, but ultimately, you should use your discretion to make the best choice for your child.
