Made from select high-density flannel/crystal velvet fabric, the pile is delicate and dense, soft and fluffy to the touch, without any cold feeling. It's gentle on the skin without causing irritation, providing warmth and comfort in autumn and winter, and breathability in summer. The inner core is filled with high-elasticity 3D PP cotton, which is highly fluffy and resilient, preventing sagging even after prolonged sitting or leaning, maintaining its full shape.

Ergonomically designed to conform to the curves of the waist, effectively distributing pressure on the lower back and relieving back pain from prolonged sitting at work, watching TV, or driving. Its moderate thickness provides just the right amount of support, whether placed behind the lower back, against the shoulder, or held in one's arms.
