This is a dosa cushion I purchased a few years ago from Les Fées in Nagasaki. It includes the original cushion insert. I've only used it as a backrest about twice. It has been stored in a room I don't usually use. (The room is ventilated.) However, the cushion insert has some yellowing. The cover is made from vintage fabric, so some aging is to be expected. Turning the cover inside out reveals some color transfer from the indigo dyeing (?). The cushion itself has no sagging. Size: Approximately 50cm wide x 30cm high (with the cushion insert inside) For those who understand the characteristics of dosa fabrics and vintage fabrics. For those who understand that this item has been stored at home. Please refrain from returns, refunds, or cancellations. Thank you.
