The U-shaped cut at the rear avoids contact with the tailbone, making it suitable for those suffering from hemorrhoids or sciatica. Eliminates the "pressure on the tailbone" that was not improved by conventional cushions or seat cushions. As a chair cushion, it naturally supports lower back pain, posture correction, and pelvic correction. 【Design that naturally leads to correct posture】A slight forward tilt naturally raises the pelvis and straightens the back just by sitting. As a posture correction cushion, it 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 doesn't hurt the buttocks. 【High-density memory foam supports long hours of sitting comfort】Adopts 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 for use as a seat cushion for chairs. Durable enough not to lose its shape even after sitting for long periods, it is a countermeasure for lower back pain during desk work and driving. *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 after 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 it provides a stable feel as a seat cushion. 【Convenient size that can be used 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. As a pelvic correction chair for desk work, as a seat cushion for driving, and as a seat cushion for living rooms and outdoors. Please use it to counter sciatica and lower back pain for everyone who sits for long hours.
