Thank you for viewing. This is a rack baby cushion, size M. I used it for about 2 to 5 months. I am selling it because I stopped using it when the baby started to roll over. I used it with a bath towel and waterproof sheet over it, so I don't think there are any noticeable stains, but there is some slight wear and tear. You can also adjust it by adding more cotton.
