IKEA / Cushion Cover Size: Approximately 50cm x 50cm There is no material tag, so it's not entirely clear, but I usually avoid synthetic fibers, so I believe it's 100% cotton. This is an IKEA cushion cover that has already been discontinued. It fits the cushion (FJÄDRAR) that is still sold. It has been washed and stored. It was only used for decoration, so it's in a clean condition.
