This seat cushion uses a low-resilience filling material that easily conforms to the body. Purchased in December 2025, I am selling it because the size did not fit my existing furniture. I have tried placing it on a chair and sitting on it, but there are no stains or anything. If you would like to purchase individual items, please comment. 【Features】 This seat cushion provides comfortable seating with its soft, low-resilience urethane filling. 【Material】 The cover fabric is a soft, stretchy fabric made by mixing elastic polyurethane with polyester. 【Thickness】 3cm 【Care Instructions】 This product cannot be machine washed. If it gets dirty, dilute a mild detergent with water, soak a towel in the solution, and gently blot the stain. Then, wipe off the detergent with a water-dampened towel and dry immediately.
