Protect a musician's valuable asset! Sitting long hours in rehearsal-in the orchestra, band, choir, or at the keyboard, can be painful on a musician's back or bottom! Highly recommended by professional musicians, this orthopedic seat cushion acts as a dual action kinetic therapy system to relieve and prevent back pain, numb buttocks and other discomforts associated with sitting. The Tush Cush suspends the tailbone in the air, reducing the pressure on the lower spinal disks, tips the pelvis forward more in line with the natural lumbar curve, and provides seating comfort for hours on end.
