92% Polyester Fiber, 8% Spandex Fiber
LUMBAR SUPPORT FOR LONG DAYS: The Purple Back Cushion molds 100 percent GelFlex Grid to the curve of your lower back, supporting posture and easing pressure so you stay comfortable through long days at your desk, in the car, or in a gaming chair.
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.
Customers find the back cushion provides excellent lumbar support and helps with back pain, with one customer noting they can sit or drive for longer durations. Moreover, the cushion quality receives positive feedback, particularly for car use. However, customers disagree on the size and value for money, with some finding it too small and not worth the price. Additionally, the cushion’s stability is a concern, as customers report it doesn’t stay in place.
