Purchased new on Yahoo! Shopping and used at home for about two months after being discharged from the hospital. It was then home-cleaned and stored. I had a long breastfeeding period after childbirth, and poor posture and dehydration worsened my hemorrhoids, leading to surgery and hospitalization. After being discharged, I couldn't live without this. The zipper is not too difficult to open and close, making it easy to put the cover on and take it off for washing, which is hygienic. Please consider this item only if you understand that it has been in someone else's possession. Thank you very much. m(_ _*)m Donut cushion Round cushion Childbirth Postpartum Breastfeeding Constipation Hemorrhoids Surgery Discharge Desk work Office work
