The JIPORIER 2-piece car seat cushion set gives you flexible support for everyday driving. The separate seat and back cushions can be positioned independently to match your posture and vehicle seat. The contoured design features a wider front and tapered rear that fits naturally between car seat bolsters. High-density foam provides firm support without sinking too deep. The 16.9-inch back cushion covers your lower and mid-back area for comfortable long drives. A multi-point stability system with anti-slip backing, anchor discs, a back strap and connecting buckles keeps everything in place during daily commutes. The removable zippered cover makes cleaning simple. Compare the product dimensions with your seat before ordering to ensure the best fit.
