Thank you for viewing my products! This is a child's cushion, perfect for use in kindergarten or elementary school. It can also be used on bicycles or chairs for meals, as long as the size is appropriate. This listing includes the cushion itself, not just the cover. When washing, please remove the inner cushion and wash the cover only in a laundry net. Size: Approximately 30cm x 28cm, with a depth of approximately 3cm (slight variations are possible) Material: 100% cotton (seersucker fabric, so it's a bit thin) Commercially available cushions are often thick, making them difficult for young children, especially those in lower grades, to sit on. Cuddly uses slightly thinner cushions. If you prefer a thicker cushion, you may find this one a bit lacking. 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 regular 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.
