I prepared this before giving birth and used it for about a month when sleeping in the Sims position. After giving birth, I used formula, so I didn't use it for breastfeeding and stored it away. I will ship it in the box. The cover and cushion have been cleaned at home. There is no sagging, and I think you can use it comfortably. A soft fabric nursing pillow, large size for comfortable breastfeeding support. - Type: Nursing pillow - Color: Blue - Size: Large - Material: Soft fabric Thank you for looking.
