Aylio Comfort Seat Cushion - Tailbone, Coccyx, Sciatica, Back Pain Relief Soft Velvet Cover Made in USA or Imported CUT-OUT DESIGN TAKES PRESSURE OFF YOUR SPINE: Sit in comfort as your coccyx hovers above the U-shaped rear cut-out, preventing lower back soreness and discomfort from prolonged sitting. CONTOURED SURFACE FOR BUTTOCKS, HIPS AND THIGHS: This cushion gently cradles your buttocks, while the ergonomic wedge structure distributes weight evenly and promotes healthy spine alignment. LIGHTWEIGHT FOR TAKE-ANYWHERE COMFORT: Measuring 18x14x3 inches and weighing only 1 pound, this seat pillow can be carried everywhere you need support- home, office desk, wheelchair, car or plane. SCIATICA AND LOWER BACK PAIN RELIEF: The chair pad provides back support by reducing pressure on the tailbone, which can help with sciatica, back pain or a herniated disc. HYGIENIC VELVET COVER ZIPS OFF FOR EASY WASHING: Don't worry about getting your seat cushion soiled or dirty from daily use. Just machine wash and air dry for fresh and clean sitting all the time.
