Improve posture and reduce pain while sitting in any seat with this helpful seat cushion. As seen on TV, OntelÃÂ¢ÃÂÃÂs Seat Solution Ultra Orthopedic Seat Cushion encourages the spineÃÂ¢ÃÂÃÂs S-shaped curve for perfect posture by tipping the lower back forward with its wedge-shaped design. Meanwhile, pressure on the tailbone is alleviated by the seatÃÂ¢ÃÂÃÂs U-shaped cutaway. Ideal for individuals with tailbone, pelvis, hip, and lower back issues, the clever cushion offers additional comfort and support with its high-density, furniture-grade memory foam construction. The 100-percent polyurethane foam cushion responds to the userÃÂ¢ÃÂÃÂs weight and temperature, molding around his or her natural curves to facilitate proper alignment and relieve pressure points for better circulation. Hypoallergenic, the memory foam cushion suits those afflicted with allergies. A built-in handle enables easy cushion transportation, from an office chair to stadium bleacher seats to the car to a church pew. With its dual-sided cover, the cushion further adapts for multiple applications. Water- and stain-resistant faux leather covers one side of the cushion, great for use in a boat, while soft, breathable micro-suede covers the other side. To clean the micro-suede, unzip and remove the cover. The faux leather is simply wiped clean. The seat cushion measures 12 inches wide by 10 inches deep by 4 inches high and weighs 2 pounds.
