The U-shaped cut at the rear avoids contact with the coccyx, making it suitable for those suffering from hemorrhoids or sciatica. It eliminates the "pressure on the coccyx" that was not improved by conventional cushions and seat cushions. As a chair cushion, it naturally supports lower back pain, posture correction, and pelvic correction. 【Design that naturally guides you to the correct posture】A slight forward tilt naturally straightens the pelvis and extends the back just by sitting. As a posture correction cushion, it maintains the correct posture without strain. It reduces the burden on the lower back even during long hours of desk work, and provides a comfortable sitting experience that prevents buttocks pain. 【High-density memory foam supports long hours of sitting】It uses a memory foam material (memory foam seat cushion) that distributes 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 its durability that does not lose its shape even after sitting for long periods, it is a countermeasure for lower back pain during desk work and driving. 【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 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. 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 countermeasure sciatica and lower back pain for everyone who sits for long hours.
