★ New, Unused Chair Cushion, Ergonomically Designed Pressure-Relieving Chair Pad Low-Rebound Type Retail Price: ¥3,790 Shipped via Yamato Transport courier service. Thank you very much m(_ _)m Brand: Vivirose Features: Breathable Color: Black Size: Standard Material: Memory Foam Shape: Square 【Ergonomic U-Shaped Design Cares for Hips and Coccyx】The W-shaped design of the front of the chair cushion wraps around both sides of the buttocks, effectively distributing pressure on the ischial bones. The U-shaped cut at the rear avoids contact with the coccyx, eliminating the "pressure on the coccyx" that was not improved with conventional cushions and seat cushions. 【Design that Naturally Guides Correct Posture】A slight forward tilt naturally straightens the pelvis and extends the back just by sitting. Maintains correct posture without strain. Reduces the burden on the lower back even during long hours of desk work, and provides a comfortable sitting experience that prevents buttock pain. 【High-Density Memory Foam Supports Long-Term Comfort】Employs a low-rebound cushion (low-rebound seat cushion) material that disperses body pressure. As a chair cushion, it fits softly while providing firm support, making it ideal for use as a seat cushion for chairs, with durability that prevents deformation even after sitting for long periods. *Recommended for those weighing 90kg or less. 【Highly Breathable Mesh Material and Non-Slip Processing】The surface is made of highly breathable mesh fabric, so it is comfortable and does not get stuffy even when sitting for long periods. The cover is washable and can be kept clean. The bottom is non-slip, so it does not slip on chairs or car seats, and provides stable use as a seat cushion. 【Convenient Size for Use in Various Scenes】Size: (approx.) 40.5 x 48.5 x 5-11cm (U-shaped type), fits various chairs such as office chairs, gaming chairs, car seats, and wheelchairs. Can be used as an office cushion, driving cushion, living room cushion, and outdoor cushion. #Chair #Cushion #Ergonomics #PressureDistribution #Chair #Pad #LowRebound #SeatCushion #NoButtockPain #Breathable #NonSlipBottom #RemovableCover #Home #OfficeChair #Wheelchair #Automobile #Presentation
