Construction Materials
Hypoallergenic and organic materials are the best for sensitive babies. Chemically laden products may cause itching and allergic symptoms when they come into contact with the sensitive skin.
Mostly, the outside cover is cotton but it can be another material. Just make sure it’s sufficiently soft and comfy and does not overheat the baby.
Size
There are small models exclusively for infants as well as longer ones that grows with the baby from birth to toddlerhood. However, it should fit perfectly between both of you without taking a huge space in the king or queen size bed.
High Sides
The elevated sides will stop the baby from rolling down at night. They position the baby centrally and make the child feel like they’re being cuddled the same way like the mom’s arms.
They also give the baby a sense of security that the environment they’re changing to is secure since it is similar to the crib. This makes transitioning into larger bed from crib a breeze.
The bumpers help create a familiar sleeping environment to the baby everywhere they sleep whether at home or away.
Removable Cover
Zippered models are the best when it comes to taking the cover out for laundering. But make sure the material is soft and derived from high quality fabrics. Stay away from those material that get discolored from frequent washing, or do not clean easily after a series of spit ups or diaper blowouts episodes.
Lightweight
Super-light model is simplest for travelling. But another important feature that you need to consider is the top carry handle to hold the lounger and transfer to another place so your baby can nap and rest safely where you are.
