This is a cushion with strings that can be tied to a chair. I haven't used it because I bought the wrong size. The size is about 35cm to 40cm. Please check the photos. It has a tag that says it can be hand-washed. The stitching on the strings in the second photo is rough, and the ends are frayed. Please purchase only if you understand this. Please refrain from purchasing if you are concerned, as it has been stored at home (⋆ᴗ͈ˬᴗ͈⋆) It will be compressed for shipping. Thank you for looking. #SeatCushion #Washable #DiningChair
