I hardly used pillows or mats, and instead used a triangular cushion directly in the baby bed for about a month. The baby bed sheets were gauze, and the gauze stuck to the Velcro, causing some fuzzing on the Velcro parts. The adhesive strength is perfectly fine, and it's still usable! There's also a pillow. The box is available, but I will use it for shipping this item, so it will arrive with tape on it.
