Thank you for viewing my products! This is a zabuton (floor cushion) that is needed for kindergartens and elementary schools. This includes not only the zabuton cover but also the zabuton itself. When washing, please remove the filling and wash it in a laundry net. Size: Approximately 30cm x approximately 28cm, gusset approximately 3cm (slight variations are acceptable) Thick zabutons can be difficult for children to sit on at kindergarten and elementary school, so this is a slightly thinner zabuton. Those who prefer a thicker zabuton may find this a little lacking. Because this is an original Cuddly size, we do not accept size changes for the zabuton cover. To prevent issues such as the cover not fitting your existing zabuton, Cuddly sells the zabuton and cover as a set, so please understand. The inner zabuton is made to fit a square shape of approximately 28cm. Shipping will be in a clear bag and a simple envelope. Please feel free to ask if you have any questions. Please purchase with the understanding that this is a handmade product. To prevent any problems, please read Cuddly's profile carefully and understand it before purchasing.
