This is a cushion cover from IKEA. It's 50x50cm, but I was using it with a 45x45cm cushion inside. The fabric is firm, making it very easy to use. The design is different on the front and back, which is nice because you can change it depending on your mood. I don't use cushions very often, so I've mostly just had it out as decoration. I've washed it regularly, and it's in relatively good condition. I would appreciate it if you could understand that this is a used item that has been in someone else's home.
