Knot Ball Pillow or Knot Cushion.

Design: Often handwoven using long, stuffed tubes of fabric (typically cotton or velvet) that are intricately knotted together.

Material: Usually filled with soft PP cotton for a plush feel, while the outer fabric varies from soft jersey to elegant velvet.

Versatility: Beyond being a decorative throw for sofas or beds, they are often used as sensory or fidget items due to their unique texture.
