PRESSURE RELIEF FOR LONG DAYS: The Purple Ultimate Seat Cushion cradles your tailbone in 100 percent GelFlex Grid, easing pressure and spreading weight so you stay comfortable through the longest days at your desk, on the road, or in a gaming chair.
SIZED FOR BIGGER CHAIRS: A large seat cushion, 21.75 by 18 by 2.5 inches, made for wide chairs and long hours. It fits office chairs, gaming chairs, and desk chairs, and slips right onto a car or truck seat for the commute.
NO-SLIP AND EASY TO CLEAN: A grippy bottom keeps the chair cushion from sliding, and the two-way stretch cover moves with you. Toss the cover in the wash and tumble dry low. The GelFlex Grid is built to bounce back, day after day, 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 travel cushion 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 seat cushion comfortable, reporting significant pain relief and immediate back pain relief. Moreover, the cushioning receives positive feedback, with one customer noting it’s ideal for 11-hour daily sitting. However, customers disagree on the size, with some finding it too large for kitchen and office chairs. Additionally, stability is a concern as it keeps sliding forward on chairs, and durability varies, with some reporting it’s still holding up well while others say it breaks down. Value for money is also mixed, with some finding it worth the price while others disagree.
