This is a cushion that comes with a KATOJI baby chair. It was very helpful during the time when the chair felt cold to sit on directly. The backrest cushion was also useful for protecting the baby's head during the months when they might bump it. It was used during mealtimes, so there is a sense of use, but I think it can still be used. How about it as a spare? #KATOJI #KATOJI #BabyChair #BabyChairCushion
