Thank you for viewing my products♡ This is a cushion for children, perfect for use in kindergartens, elementary schools, and more. It can also be used on bicycles or chairs for meals if the size is appropriate. This listing includes both the cushion cover and the cushion itself. When washing, please remove the cushion from the cover and wash the cover only in a laundry net. Size: Approximately 30cm x approximately 28cm, with a depth of approximately 3cm (slight variations are possible) Fabric: Car pattern (American) - 100% cotton The fabric is not pure white, but rather a natural off-white color, making stains less noticeable. Commercially available cushions are often thick, making them difficult for young children, especially those in lower grades, to sit on. At Cuddly, we use slightly thinner cushions. If you prefer a thicker cushion, you may find this one a bit less supportive. We create our cushions in Cuddly's original size, so we do not accept size changes for the cushion covers. To prevent issues such as the cover not fitting your existing cushion, Cuddly sells the cushion and cover as a set. Thank you for your understanding. The inner cushion is made to fit a square shape of approximately 28cm. Shipping will be in a clear bag and a simple envelope. We plan to ship via non-standard mail, so please understand that there is no compensation for loss or damage. The pattern appearance will vary. Please feel free to ask if you have any questions. Please understand that this is a handmade product.
