  • BEFORE YOU BUY (OFFICE OPTIMIZED): Designed for maximum tailbone relief, our XL memory foam cushion requires a minimum chair surface of 18.7" x 16.3". Please note that its premium dense core will elevate your seating height by approximately 4.6 inches. Perfect for spacious office chairs, ensuring you get the ultimate ergonomic support without bottoming out.
  • U-SHAPED COCCYX CUTOUT — Rear opening reduces direct contact under the tailbone area for everyday comfort.
  • CONTOURED MEMORY FOAM — Raised sides and sloped front edge support a stable position without a sharp leg edge.
  • NON-SLIP BOTTOM — Grip dots help reduce movement; performance varies on curved, leather or narrow seats.
  • BREATHABLE REMOVABLE COVER — Mesh cover promotes airflow and removes through a concealed zipper for washing.
