Purchased from Tamahiyo Shop for about 6400 yen. Can be used from pregnancy through postpartum. During pregnancy, it can be used as a body pillow, allowing you to lie down in a comfortable position. After the baby is born, it can be used as a nursing pillow. The cover is 100% cotton. According to the shop website, the cushion has anti-mite fabric, 0% mite passage rate, and is washable. I have a cat (=^・^=), and it seems the cushion was kneaded, resulting in scratches inside. Please check the photos. We appreciate your consideration if you understand this point. Thank you for viewing.
