Thank you for viewing. 【Specifications】Size: Small Round: 42cm, thickness 6-8cm; Large Round: 55cm, thickness 10-12cm. Please allow for a 5% error in the fluffiness of the seat cushion. The marked sizes are measured straight from corner to corner. If you have strict size requirements, please choose carefully. 【Material】Outer layer: Corduroy fabric; Filling: Polyester fiber cotton. Corduroy fabric: High-quality luxurious fabric, warm, soft, thick, delicate, soft and breathable, making it the perfect product for autumn and winter homes. I purchased this around August of last year and used it at home for about 3 months, but I stopped using it due to moving and have been storing it. There is a black ink mark from a pen, about 1cm in size, in one place. I think it will come off if washed. I usually take care of my belongings, but please understand that this is due to amateur handling.
