Product Use and Safety


The Zen Swaddle® and Zen Sack™ are equally effective for naps and nighttime sleeping. With consistent use, our products will become a key part of your baby's sleep routine, signaling that it is time to fall asleep! For a step by step explanation of how to use the Zen Swaddle, please click here.


Both the Zen Swaddle and the Zen Sack can be washed frequently. The materials we use in our products are designed to withstand frequent spit-ups and the subsequent multiple washes, as well as your little one’s vigorous kicks and wiggles.The garment’s construction ensures filling stays in place through repeated washes. To protect the quality of fabric, we recommend washing in cold water, on a gentle cycle and drying using low heat.


At Nested Bean, we take infant safety very seriously. First and foremost, all of our products have been designed according to the AAP's Guidelines for Safe Sleep. Additionally, the weight in our products is maintained well below the recommended weight to body-weight ratio according to physiotherapy therapy standards (1:10). Throughout the development process, we worked with multiple safety laboratories, all of whom are accredited by the Consumer Product Safety Commission. These safety firms were involved at multiple stages of our product's design, to ensure safety in both design and quality. The Zen Swaddle and Zen Sack have undergone many tests, to meet both mandatory as well as voluntary safety standards. Below is a list of the specific safety tests that our products have undergone:

Test Name Description

Construction Safety Tests:

  • CO2 Rebreathing
  • Suffocation Hazard
  • Seam Strength
  • Sharp Edges and Sharp Objects

Construction of the Zen Swaddle and Zen Sack has gone through many rigorous voluntary and mandatory tests. We ensure that: 1) The swaddle, under intended and unintended use, will never pose any risk of suffocation in a baby's sleep environment, 2) Pellet pockets are sewn strong enough to prevent the poly-beads from escaping, 3) Velcro and zipper ends are not sharp or abrasive to cause the baby accidental harm.

Fabric Quality Tests:

  • Shrinkage
  • Pilling
  • Color Fastness
  • Flammability

We ensure that our products are manufactured with the highest quality fabric, that will withstand multiple washes and be thick enough to pass flammability tests without needing to be treated with flame retardant chemicals.

Chemical Detection Tests:

  • Lead Detection
  • Phthalate Detection
  • Azo Dyes Detection
  • Formaldehyde Detection

All raw materials used to construct the Zen Swaddle and Zen Sack are thoroughly tested to ensure that they do not contain harmful chemicals or dyes.


Temperature control is important as newborns are not good at regulating their own temperatures. The temperature in your baby’s room should feel comfortable to an adult in light clothing. The light-weight fabric our products are constructed from ensures your baby will not overheat due to swaddling alone. The filling density in the weighted parts of the swaddle or sleep sack is kept to the minimum to balance effectiveness and your baby’s safety.


• When laying baby down for swaddling ensure proper positioning of swaddle wings and weighted areas around your baby, by placing infant’s shoulders no lower than 1 ½ inches below the top edge of the back panel.
• Do not allow infants to slide down inside swaddle. Place infants less than 23” tall or less than 1 month old with feet inside the inner pocket and pull pocket over waist. Fold any extra fabric at the bottom of the swaddle up over torso and secure with swaddle wings.
• Swaddle wings must be securely tucked under your infant’s body. However, ensure swaddle is not too tight by slipping your hand between baby and swaddle; it should feel snug but not uncomfortable.
• Ensure the Loving Embrace™ is placed on each side starting under infant’s arms down to the thigh. Do not allow to move up onto infant’s chest.
• Ensure the Peaceful Touch™ is always placed on the lower chest and the top edge of blanket covering the baby is always at the chest level, never above your infant’s neck or covering his or her nose and mouth.
• Never use swaddle with products with restraints such as car seats, strollers, swings, etc.


• Experts say proper swaddling reduces the risk of SIDS. However following safe swaddling practice is just as important for the safety of your baby.
• A swaddle must be securely tucked under infant’s body. However ensure that swaddle is not too tight by slipping an adult hand between baby and swaddle; it should feel snug but not uncomfortable.
• Never swaddle using any product when your baby is sick, has a cough or fever in order to prevent restriction in breathing.
• Always place baby on their back to sleep, especially when swaddled.
• Always remove swaddle from crib when not in use.
• Never use a swaddle with products with restraints such as car seats, strollers, swings, etc.


• Do not use any objects such as pillows or soft toys in your infant’s sleeping environment.
• Never place your swaddled infant on soft surfaces such as your bed, a couch, an air mattress etc. as your baby can rollover and suffocate.
• Never sleep with your child in an adult bed, an adult can roll on top of an infant and suffocate them.
• Place your baby to sleep in an appropriate sleep product such as a crib, cradle, or bassinet.
• Use discretion when using any covering on your infant in warm rooms. Take care and periodically check that your baby is not overheated. Overheating may be a factor in SIDS. Do not over bundle.
Always provide supervision for continued safety of your child. When not sleeping, never leave your baby unattended.
