Thank you for looking. This is a set of two living room cushions, pink and brown. These are low-resilience urethane cushions with a thickness of 13cm. I purchased them more for interior decoration than for sitting, so I believe they have not become flattened or dirty. I didn't sit on them very often, so I had them on the floor in the living room for about six months, and then they were stored in the closet. I think I bought them at Nitori. The covers are washable. The low-resilience material is not flattened. The covers have some fading due to age. Thank you to those who can understand this. Thank you.
