This is a set of Topvalu low-rebound round cushion and low-rebound lumbar support cushion. I used them for about 5 days when visiting my child during their hospitalization. After that, I stored them at home for about a year and a half. The color is listed as navy. I didn't see any noticeable stains or dirt, but the round cushion has some yellowing due to aging, so please check the photos. Only the round cushion cover can be removed. The lumbar support can be fixed to a chair with Velcro. Thank you.
