I bought this for my child who was experiencing severe reflux. The design is stylish and cute, and the colors are calming, so it blended well with the interior decor. When my child was crying or seemed uneasy, they would carry this cushion around and keep it nearby to observe. The cover is removable and made of 100% cotton, making it easy to wash. Both siblings used it, and because they took good care of it, there were no stains on either the cover or the filling (please forgive any oversight). The filling is still bouncy and hasn't lost its shape. The cover has been home-cleaned. The dedicated storage bag has some stains (yellowing?). The following is quoted from the official website: *Product Size W480 x D600 x H200mm *Product Weight 1,780g Please feel free to contact me if you have any questions! Thank you for looking.
