【Online Price】 ¥2,480 【Two-Layer Structure to Reduce Sitting Fatigue】This cushion is neither too soft nor too hard. The top layer of memory foam cushions the body, while the bottom layer of high-resilience foam maintains posture. It provides double care for "aching buttocks" and "lower back fatigue" when sitting for long periods, ensuring a comfortable sitting experience that prevents buttock pain whether you're desk-working or sitting on the floor in the living room. 【Choose Your Preference with Front and Back】The surface is soft memory foam, and the back is firm high-resilience foam, with a reversible design. Whether used as a chair cushion or a floor cushion, simply flip it over to suit your body type and the situation. Even if the family shares one, everyone can find their "just right" comfort. 【Designed to Adhere to Chairs】Silicone granules on the bottom of the cushion prevent slipping on any chair. No need to worry about the cushion sliding when you quickly stand up during a phone call. Keeps you focused on work or hobbies. 【Easy-to-Remove, Washable Cover】With a zipper, the cover is easy to remove and attach♪ Coffee spills can be easily washed in the washing machine. The fabric is designed to maintain its shape, so the "fluffy comfort" lasts even after repeated washing. 【Solves Hard Chair Problems Throughout the House with One Cushion】This chair cushion can be easily placed on office chairs, dining chairs, car driver's seats, and even floor chairs in Japanese-style rooms. Those who "dislike sitting on hard chairs" will especially appreciate the difference this chair cushion makes, offering versatile convenience. ※We have compressed the product as much as possible.
