BabyBjorn One Kai Air - Mesh Usable from newborn to around 3 years old. Used for a little over a year. The instruction manual is not included, so please refer to the tag attached to the main unit or search online (there are also videos on YouTube). It has been home-cleaned, but since I have a cat, I can't completely remove all the hair even with thorough use of a lint roller. Please purchase only if you are not overly concerned about this.
