The cushion cover is 50 x 50. So very large! The back is made of soft cotton fabric with a zipper. At a price of between 26 - 30 euros, depending on the promotion and the size of the cushion, you should not expect top quality. There are a few knots and threads in the woven wool fabric on the front that you can get used to. After a while you will only see the pretty pattern. Do not wash the cushion cover in the washing machine as it will discolor. Either dry clean or hand wash. I use the aloe vera liquid soap from Styxx for hand washing in the shower. It is also available here on amazon. This liquid soap from Styxx leaves the wool material nice and fresh and soft. Do not leave the cushion cover in the soapy water for too long, as the colors will come off. Do not use fabric softener. The Styxx liquid soap softens enough.
