Thank you for viewing. I purchased this for my second child, but I didn't use it much. However, I did take it out of the bag and stored it, so there may be some slight deterioration. Otherwise, there are no stains, and there are no functional problems. It's made of vinyl material, so you can easily wipe it clean if it gets dirty. It's also compact, making it convenient to carry when you go out. Size: Approximately 70cm (height) x 46cm (width)
