Made with high-quality memory foam, it's comfortable even for long periods of sitting, such as desk work, long drives, and working from home. It naturally conforms to the body's lines, reducing stress on the lower back, and can be stacked to use as a stool. Offers peace of mind with a 5-year deformation guarantee (small air bubbles on the cushion surface are a natural result of foaming and enhance breathability). 【Full Silicone Non-Slip! Stable and Secure】 The entire bottom of the cushion is covered with high-density silicone particles, providing a "firm grip" on any chair, including office chairs (leather/fabric), car seats, and wooden dining chairs. Significantly reduces unconscious posture adjustments during work and slipping during meals, creating a comfortable seating space for concentration. 【Machine Washable! 100% Polyester Cover】 The removable 100% polyester cover can be machine-washed to remove pet hair and everyday dirt, keeping it fluffy and clean. It's breathable, making it less stuffy in the summer, and provides moderate warmth in the winter, allowing for year-round use. (Note: The cushion itself is not washable.) 【Suitable for All Indoor and Outdoor Scenes! Perfect for Gifts】 Can be used in various indoor and outdoor settings, such as offices, homes (telework/kotatsu), cars (driving), balconies, and tents. Its versatility allows it to be placed on low tables and wheelchairs, making it a great gift for family and friends. Instant purchase 〇 Silent purchase at midnight 〇 Thank you for viewing.
