Three-dimensional breathable mesh fabric: Both the backrest and seat cushion are made of a special breathable mesh fabric with high toughness and elasticity, forming a comprehensive three-dimensional ventilation system. This effectively promotes air circulation and quickly dissipates heat and moisture, keeping the back and legs dry even after prolonged sitting in summer. Scientific zoned support structure: The mesh fabric is not a flat sheet but is scientifically woven in zones according to the curves of the human body. Differentiated tension designs are used in the lumbar, shoulder, and seat cushion weight-bearing areas, providing elastic support while ensuring strong support for key areas and relieving pressure concentration. Adaptive dynamic lumbar support: The backrest has a built-in adjustable curved lumbar support that actively adapts to changes in the lumbar curve under different sitting postures, providing continuous and flexible support to help correct posture and reduce spinal burden. Multi-dimensional flexible adjustment: Supports personalized adjustments to seat height, armrest height, backrest recline angle, and elasticity. Combined with a synchronized tilt system, the seat cushion angle moves accordingly when reclining, ensuring body balance and providing consistent support from sitting upright to relaxing in a reclined position. Soothing and stress-relieving seat cushion: The seat cushion is filled with high-resilience sponge, and the front edge adopts a waterfall edge design to reduce pressure on the back of the thighs, promote blood circulation in the legs, and make you feel relaxed even when sitting for a long time.
