Breathable skin-friendly fabric on both Car Back Support and Car Seat Cushion keeps users feeling fresh, even during extended periods of sitting. Black Car Cushions set is designed for durability; memory foam retains shape over time, and fabric resists wear for lasting use. Integrated Lumbar Support Pillow for Car features a 28.74inch tall design that provides continuous support from neck to hips, fitting natural spinal curves for dynamic body alignment during drives. Integrated Car Seat Back Support installs easily to most vehicle seats, staying securely in place without shifting while driving.
