Ready for the best sleep of your life?

Purple delivers an instant upgrade over traditional mattresses thanks to our patented GelFlex Grid technology. 1,400+ gel columns work together to support broad surfaces like your back while cradling pressure points like shoulders, hips, and knees. Unlike memory foam, the GelFlex Grid doesn’t trap body heat, and instantly adapts to movement for proven deeper sleep.

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.
