Bionic Design Concept and Easy Sleep: The baby lounger simulates a 360-degree surround compact space, making the baby feel that he/she is staying in a comfortable uterine environment. This brings a sense of security to the baby, helping to reduce anxiety and making the baby comfortable to play, rest, and nap. The bed nest snuggle pillow is used from birth until the baby can roll over. Fully Breathable Fabric, Refreshing and not Stuffy: The baby nest uses a 3D fabric honeycomb structure, which is comfortable and breathable, removes excess heat and moisture, and can keep the bed breathable and fresh after a long time sleeping. It is suitable for hand washing and dry cleaning. The crib measures approximately 20 x 14 inches, and it fits a 0-6 months' baby comfortably. Growing Design, Double U-Shape Pillow Cushion With Detachable Structure: Our baby sleep positioner is an adjustable baby recliner. You can adjust the U-shaped headrest and U-shaped leg rest at any time according to your baby's size. The baby recliner adapts perfectly to your baby's body, providing optimal head and back support and elevating the newborn's head and legs. 1.96 in High Side Fence for Protective Pad: The right height creates a safety cover for the baby, which the baby won't roll out from. Moreover, it can effectively isolate the baby, prevent adults from pressing the baby when they fall asleep, creating a separate sleeping space for baby when sleeping in bed with the parents, encouraging your baby to develop independent sleeping habits, and helping her/him sleep better than ever. Portable And Fit Anywhere: The portable crib is lightweight (9.8 ounces) and the foldable design makes it easy to insert into any stroller, baby rocker, rocking chair, crib bedding, cradle or car seat, and more. Whether your baby sleeps at home in their nest sleeper or on a trip, you can secure your baby in a portable bed.
