Specification AgeRangeDescription : Adult Brand : AUVON BulletPoint1 : Innovative Composite Materials for Balanced Support & Softness: AUVON's team conducted market research on seat cushions and discovered that users needed a balance of firm support and softness. As a result, the team innovated a chair cushion with a new combination of soft-cloud and extra support memory foam, achieving an ideal balance comfort. The soft memory foam conforms to your legs, while the support layer offers long-lasting support without flattening. BulletPoint2 : 5 Scientific Areas for Contoured Relief: This office chair cushion is designed using ergonomic principles and features 5 scientific areas. The upward area provides contoured comfort for your buttocks, while the tailbone area includes a cutout for tailbone pressure relief. There is also a scientific hole for hemorrhoids to reduce compressive pain, a W-shape design to support your thighs and promote correct sitting posture, and a hip-wrap area to distribute sitting pressure evenly. BulletPoint3 : Scientific Design of Central Hole: Unlike the traditional donut pillows with over large central holes, this hemorrhoid seat cushion is designed with a scientific central cutout of 3.4''L x 9''W based on anatomy for hemorrhoid relief. The seat pillow can accurately match the lower body structure by suspending the hemorrhoidal area to care for sensitive areas. Ergonomic designs can meet your real soothing needs of sitting.
