ADJUSTABLE STRAP FITS ANY SEAT: A strap and buckle hold the back cushion in place on office chairs, gaming chairs, car seats, and recliners, no sliding. Measures 15.75 by 9.25 by 2.5 inches and pairs perfectly with any Purple seat cushion. WASHABLE AND BUILT TO LAST: The cover comes off for cleaning, machine wash cold and tumble dry low. Underneath, the GelFlex Grid is built to bounce back, day after day, holding its shape and support without going flat. STAYS COOL ALL DAY: Hundreds of tiny air channels run through the GelFlex Grid, and the temperature-neutral material won't trap heat. Air keeps moving so the lumbar support pillow stays cool and breathable, even through the longest days. CUSHION INNOVATION YOU CAN FEEL: Born from over 30 years of innovation and 200-plus patents, the GelFlex Grid delivers cool, no-pressure comfort unlike anything else. Purple feels different because it is different. Try it to believe it.
