Chair Cushion for Sciatica/Lower Back Pain/Posture Correction/Hemorrhoids - Chair Pad, Low-Rebound, Seat Cushion, Doesn't Hurt Your Butt, Pressure Distribution, Breathable, Non-Slip Bottom 【Ergonomic U-shaped design cares for the lower back and coccyx】The W-shaped design at the front 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, 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. 【Designed to naturally guide 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 doesn't hurt your buttocks. 【High-density memory foam supports long hours of sitting】It uses a low-rebound cushion (low-rebound seat cushion) material 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. It has a durability that does not lose its shape even after sitting for long periods, and 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 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.
