Najell Sleep Carrier in excellent condition, bought late last year. As good as new. Use as a carrycot and play mat: The Najell Baby Nest SleepCarrier has several functions, all designed to complement your needs as a parent. You can adapt the size of the infant baby nest according to your baby. By adjusting the drawstrings, you can easily change the newborn nest size. Opening it up partially or fully. When fully flat, it transforms into a soft play mat so you and your baby can practice tummy time together.
