【Adaptive Dual-Wing Lumbar Support】The dual-piece lumbar system gently wraps your lower back and adapts to your movement, maintaining consistent contact for balanced support during long hours of sitting.
【7D Synchronized Armrests】Engineered for multidirectional adjustment, the 7D armrests move with your posture to support typing, reclining, and focused tasks while reducing shoulder strain.
【Dynamic Recline】Featuring 4 locking positions, the backrest reclines up to 145°. The upper back tilts and the lumbar glides in sync, maintaining ergonomic alignment as you lean back.
【Height-Adjustable Structural Backrest】The backrest lifts up to 1.57″ to achieve a more precise fit for different torso heights, ensuring proper support across a wide range of users.
【Premium Construction & Smooth Mobility】Built with a durable metal base, integrated footrest, wired control system, and quiet-rolling casters for long-term stability and seamless movement across floors.
