■ Product Chair Cushion Ergonomic Pressure Dispersion Chair Pad Low-Resilience Seat Cushion Doesn't Hurt Your Buttocks Breathable Non-Slip Bottom Removable Cover Home/Office Chair/Wheelchair/Car ※Please purchase if you don't mind that it's stored at home. ■ Product Description 【Ergonomic U-shaped Design Cares for Your Lower Back and Coccyx】The W-shaped design at the front of the chair cushion wraps around both sides of the buttocks, effectively dispersing the 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 by conventional cushions and seat cushions. 【Design that Naturally Guides You to the Correct Posture】A slight forward tilt naturally straightens the pelvis and extends the back just by sitting. Maintains the correct posture without strain. Reduces the burden on the lower back even during long hours of desk work, and achieves a comfortable sitting experience that doesn't hurt your buttocks. 【High-Density Memory Foam Supports Long Hours of Sitting】Employs a low-resilience cushion (low-resilience seat cushion) material that disperses body pressure. As a chair cushion, it fits softly while providing firm support, making it ideal as a seat cushion for chairs, with durability that doesn't lose its shape 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's comfortable and doesn't get stuffy even when sitting for long periods. The cover is washable and can be kept clean. The bottom is non-slip, so it doesn't slip on chairs or car seats, and it provides a stable feel as a seat cushion. 【Convenient Size for Use in Various Scenes】Size: (approx.) Length 40.5 x Width 48.5 x Thickness 5-11cm (U-shaped type), fits various chairs such as office chairs, gaming chairs, car seats, and wheelchairs.
