I used this for about a month after being discharged from the hospital. The cover has been washed. Please purchase only if you understand that this is a used item. Product Information Material/Composition: Cushion: High-resilience urethane Cover: Brushed material (nylon) Size/Dimensions: 【Outer circumference】: 40cm (length) x 32cm (width) x 6.5cm (thickness) 【Hole】: 17cm (length) x 10cm (width) Weight: Approximately 400g Design/Concept: 【For postpartum mothers!】 This "donut cushion" was created for those who find it painful to sit due to episiotomy, hemorrhoids, etc., that occur during childbirth. It is a donut-shaped (oval) cushion designed to prevent the perineum and buttocks from touching the ground when sitting. 【Commitment to Product Development】 While various manufacturers sell "donut cushions" and "postpartum cushions," Rozally's donut cushion offers a unique "comfort" and "durability." We have obtained samples from over 20 factories that handle cushions and manufacture only at a select factory that meets international quality standards. 【Differences from other companies】 Some products, even those of similar design, tend to "lose their shape" quickly with use. According to the factory, this often happens with products where the sponge formation process is not given enough time to prioritize production speed. Rozally's donut cushion takes its time in the sponge formation process and sells only products with a recovery rate exceeding 99.6%. Please experience the difference in "commitment" from inferior products that only look the same. 【Improved Cover】 Regarding the cover, we have incorporated valuable feedback from customers, such as "I want to wash it because I sweat," and made improvements. The cover is removable and can be easily washed in a home washing machine. Also, we compared various samples of cover materials, including mesh, cotton, linen, and brushed materials, and adopted a gentle brushed material with a suitable texture for a delicate period. 【Target Audience】 The design prevents the perineum and buttocks, which are common postpartum concerns, from touching the ground, so it is also used by customers who suffer from sciatica, prostatitis, coccyx pain, etc. Donut cushion Hole cushion Donut-shaped cushion Preparation for childbirth
