This ergonomic saddle stool chair is a perfect blend of comfort and functionality, ideal for medical, dental, and office environments. The one-piece backrest, made from a robust combination of 70% PP and 30% fibreglass, naturally fits the neck and spine, providing excellent support. The premium 3D flocked nylon mesh is not only skin-friendly but also anti-slip, ensuring a comfortable and secure seating experience. The flip-up armrests allow the chair to slide easily under desks, saving space and making storage and room placement incredibly convenient. The fully unified colour scheme across all components, including the backrest, armrests, seat, base, and casters, adds a vibrant and cohesive look that complements any home or office space. The soothing rocking mechanism allows for smooth forward and backward tilt, enhancing lumbar comfort during long periods of sitting. Built with a 10-layer curved board, premium moulded foam, and a PP base shell, the cushion meets US fire resistance standards, ensuring durability and safety. The medium butterfly chassis with an upright position lock and a robust 2.5mm thick explosion-proof mechanism guarantees daily safety and stability. The thickened aluminum alloy track provides superior lumbar support, being significantly sturdier, rust-proof, and unbreakable compared to plastic tracks. The dual-function lever simplifies operation, allowing for easy control of both seat height and the rocking mechanism. Supported by a durable nylon 5-star base, this chair has passed the BIFMA 1136kg static pressure test, ensuring structural stability and reliability.
