Sturdy, snug work chair designed for long sessions over 8 hours of desk work. It features micro-adjust lumbar support, flip-up arms, and a flexible headrest to accommodate individuals from 5'5" to 6'2", extending comfort. BIFMA X5.1 certification confirms the reliability of its robust, durable structure, ensuring sustained performance. The lumbar micro-adjust provides 2 inches of adjustable support across 8 levels, aligning precisely with the L1-L5 lumbar spine. This reduces lower back pressure by 50% and diminishes fatigue by distributing weight evenly. The larger, cooler seat includes an enlarged cushion (19.3"D x 20"W / 18.5"-22.05"H), made from exclusive Aerovith Mesh. It maintains continuous cooling while boosting support by 30% and cutting pelvic pressure by 20%. It is paired with a durable stainless steel base that holds up to 400 lbs. Detail-oriented features comprise wide, non-peeling soft armrests with a 90° flip-up function, combined with silent PU wheels. This enables the chair to roll smoothly under the desk to optimize your workspace without leaving marks on the floor. The flexible head and backrest can be adjusted in both height and depth for customized head and neck support for people between 5'5" and 6'2". The backrest can be locked at 90, 110, or 125 degrees to match your changing focus needs throughout the day. Choosing the right chair is crucial for prolonged comfort and steady productivity.
