Travel becomes less of a hassle with nuna's SENA crib—now with an advanced design that allows airflow from every angle. The easy-open playspace features a ventilated, quilted mattress that pulls away heat and humidity from baby's skin. The mattress can be placed in a higher bassinet position that’s easy to reach when baby is tiny, then moved to a lower position when your little one starts pulling up and getting more mobile, and eight zigzag, skid-proof support legs help to increase stability. The smart leg design allows one-hand fold-up, and everything folds with the frame and slides into the included travel bag for easy packing or storage. Skid-proof feet and padded edges ensure quiet, pinch-free operation, so you and baby both get a good night's sleep.
