The U-shaped cut at the rear avoids contact with the coccyx, eliminating the "pressure on the tailbone" 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 provides a comfortable sitting experience that prevents your buttocks from hurting. ❇️ 【Supports comfortable sitting for long hours with high-density memory foam】 Uses 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 for use as a seat cushion for chairs, with durability that does not 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 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 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. Can be used as an office cushion, driving cushion, living room cushion, and outdoor cushion. Meets the needs of everyone who sits for long periods. s142-02302
