Purchased around May 2025. Used for about 2 months, but unfortunately, I spilled a lot of milk on it, causing stains. The outer cover has been washed, so the stains aren't very noticeable, but the inner cushion cannot be washed. I only wiped it with a towel and dried it, so the stains are quite visible. Please check the photos for the extent of the stains. Please refer to photo 7 for the material and size. Although the stains are noticeable, there shouldn't be any problems with using it.
