Hardly used. I washed the cover with water, but it seems I threw away the main body at some point. Only the cover for the Sandesica Sleeping Pillow, Colorful Animal pattern. Perfect for a change of mood, etc. Sandesica Baby cushion Inclined pillow Baby anti-vomiting pillow Anti-vomiting cushion Both the cover and the inner cushion can be washed, so you can use them cleanly. The back side uses non-slip fabric to prevent slippage. [Cover] Surface: 100% cotton Back: 100% polyester (non-slip fabric) Baby mat with colorful animal patterns
