I purchased this new and used it for 3 days after being discharged from the hospital. I am no longer using it as the wounds from childbirth have completely healed. 【Regarding the odor of the U-shaped cushion】Due to the nature of the cushion material (polyurethane foam), an odor may be present. There is no harm, so please try airing it out in a well-ventilated area for 2-3 days, which should eliminate the smell. 【Original Mold】This U-shaped high-resilience maternity cushion is something that didn't exist before. The reason is that there was no mold needed to form the cushion. Creating a mold from scratch is costly, so existing molds are generally used. However, because the O-shape couldn't fully support the affected area, we decided to create an original mold and commercialize the product. We hope it can alleviate your discomfort. 【Water-repellent and stain-resistant】Unlike fabric products, you can easily clean it by simply wiping it if you spill water or get it dirty. It is also resistant to dust, hair, and dirt, making it safe for homes with small children or pets. 【Good because it's analog】Symptoms vary from person to person. You know your own pain better than anyone else. It's difficult to conform your body to a pre-made shape. Therefore, we took a different approach. Please adjust the shape manually to suit your symptoms. You should be able to find your best position. 【Freedom of body pressure】The opening angle of the U-shape changes the area of pressure. And the way the body pressure is applied is completely different. Please check the comparison images using a body pressure measuring device. 【Especially great for postpartum mothers】We have received many comments such as: "It reduces the tendency to lean forward," "It alleviates pain from the wound," "You can sit avoiding the painful area," "You can sit for long periods," and "I like that I can adjust it myself." Of course, we also recommend it to pregnant mothers before childbirth, so please give it a try. 【Safe and clean】The back has a non-slip feature, reducing the risk of slipping off the chair. Also, the cover is removable and washable, so you can always keep it clean. 【Size and Weight】Width: 38cm, Depth: 30cm, Height: 7cm *Tip 4cm, Hole: Width 18cm, Length 9-19cm, Gap: 4cm~, Weight: Approximately 400g *Compact and lightweight, making it easy to carry around.
