The Extended Tush-Cush orthopedic seat cushion is scientifically designed to relieve and prevent back pain, numb buttocks and other discomforts associated with sitting. The unique cutout section of the cushion suspends the tailbone providing comfort and relief to areas sensitive to sitting. Wedge shape tilts your pelvis forward to restore your spine's natural lumbar curve. The Extended Tush Cush is the original design of the wedge shaped cushion with cutout. Our cushion is made of the highest quality foam to maintain the integrity of the wedge and give you the best support possible every time you sit. 90% of all Americans suffer from lower back pain! Back pain has edged out the common cold as the primary reason for lost work time. Increase productivity by using a Tush-Cush/Car-Cush at work. Business executives, secretaries, pilots, travelers, truck and bus drivers and any persons who sit for prolonged periods of time will benefit from a Tush-Cush/Car-Cush.
