Meditation cushions, often called zafus, are specially designed pillows that provide support and comfort during meditation practices. They help maintain proper posture by elevating the hips above the knees, which can reduce strain on the lower back and promote a more stable sitting position. These cushions come in various shapes, sizes, and materials, catering to different preferences and meditation styles. Some are filled with natural materials like buckwheat hulls or kapok, while others may use foam or synthetic fillings. Using a meditation cushion can enhance the overall experience by allowing for longer, more comfortable sessions.
