This is not your grandmother's float cushion: unlike traditional flat float cushions, this ergonomic cushion has three pressure points to relieve your pressure: two in front of your legs and one behind your tailbone, so so you can sit comfortably and pain- free for longer. Stress relief anytime, anywhere: contouring allows for better weight distribution, circulation, posture and alignment, no matter where you use it. Use it at home or at work, in the car, on the bus, on the train or on the plane, at the cinema, in a wheelchair... anywhere you need to be seated comfortably. Helps pad stay in place Comfortable and Cool All Day: Premium foam dissipates heat without feeling too firm or soft, even after hours of use. And since it doesn't retain heat like most memory foam pillows, you'll stay cool and sweat-free. COMPACT, LIGHTWEIGHT AND WASHABLE: Weighing around 700 grams, this pillow is small and light enough to carry and store easily. Want to wash up? Simply remove the velvet cover and put it in the wash
