Frequently asked questions
What is The Cuddle Effect™?
Medical experts agree: it’s not just the swaddling, the rocking, the lullabies that soothe your baby to sleep. It’s your touch. And it’s vital to your baby’s well-being. Recent scientific research on Deep Touch Pressure (DTP) shows that babies experience the Cuddle Effect when they feel gentle pressure in the places you naturally hold them. That means longer, sweeter sleep—until they’re back in your arms.
Which size is best for my baby?
For the product you are considering check its size chart. Your baby should not be below the minimum weight and should have at least 2-3 inches to grow before growing past the maximum height.
What’s the difference between Classic, Premier, and Winter products?
The Classic line is perfect for year-round use! The fabric is 100% cotton.
The Premier line is more lightweight and breathable than the Classic line, making it perfect for warmer climates or babies who overheat easily! The fabric is a blend of 70% bamboo + 30% cotton.
The Winter line is the warmest option, perfect for cooler climates or A/C in the summer! The fabric has two layers of 100% cotton with a heavy poly-fiber filling in between.
Is the Zen Sack™ safe for babies who roll over?
The Zen Sack is perfectly safe for babies who roll during sleep! The weight is light and flexible, so it will nearly flatten underneath your baby's body. For tummy sleepers - who can roll completely independently - the Zen Sack can be worn backwards!
How much weight is in each product?
Physiotherapy standards were used to determine the appropriate weight in the Zen Sleepwear. These weight requirements ensure that the weight to body-weight ratio is maintained well below the recommended Physiotherapy standard of 1:10. Depending on the size of the product, the weighted parts range from 1 to 5 ounces.
