Waterproof chair covers, gray beige, set of 4. 92% polyester, 8% spandex. Hand wash or machine wash. I am selling these because the size didn't fit my chairs at home, as the chair seats are rounded towards the front. I only tried them on the chairs once, but there are wrinkles and scratches as if something had caught on them since I bought them. They seem less noticeable if you use them taut, without any slack.
