This is a kids' mattress from Yamatoya Soinel. I accidentally purchased this and couldn't return it, so I've been storing it at home. I thought I'd use it when my child turned 2, but my storage space is limited, so I'm selling it. - Product Name: Dreamy Cloud - Target Age: For children - Breathability: Excellent breathability - Structure: Structure that facilitates air circulation - Material: Fiber mat Original price: 14,300 yen Includes shipping Thank you for looking.
