The Nuna LEAF™ grow is a stylish seat that's designed specially for them. A gentle nudge from you starts a smooth and rhythmic side-to-side motion that lasts unassisted for over two minutes. It soundlessly operates without the use of batteries and its sway-safe base ensures that they're secure and relaxed. With breathable mesh backing and a super-soft organic insert, it's a safer and healthier choice for baby.
