Pro tip: For best stability on leather or mesh chairs, ensure the grip side is fully in contact with the seat surface. MACHINE WASHABLE - INCLUDES 2 COVERS IN SEALED, QUALITY-CHECKED
PACKAGING: Every cushion ships with both a primary cover AND one spare cover - fully factory-sealed and quality inspected before dispatch.
