It aligns with the natural curves of the hips and thighs, evenly distributing weight, relieving coccyx pressure, easing sciatica, and ensuring long-lasting comfort. 【Enlarged Size, Multi-Scene Use】 Enlarged 46 cm × 43 cm × 11.5 cm design office chair cushion provides wider seating coverage for different body types and helps distribute sitting weight more evenly, making it suitable for office chairs, car seats, dining chairs at home, and gaming chairs across various everyday sitting environments. 【Triple-Layer Structure, Adaptive Rebound】 Layered coccyx cushion for tailbone pain design with cool-touch fabric, high-density slow-rebound memory foam, and a non-slip silicone grid base, maintaining shape under use and providing stable support for everyday sitting and standing. 【From Office to Car, Stay Cool All Day】 Whether you're an office worker, long-distance driver, student, or casual user, this ice silk blended pressure relief cushion provides customised support. Its breathable bottom layer helps dissipate heat and moisture, ensuring a fresh, comfortable experience even during long periods of sitting. 【Shape Retention, Everyday Comfort】 Memory foam sciatica cushion designed to retain its shape while adapting to body contours, providing consistent support for use on aircraft seats, car seats and office chairs during extended sitting.
