About this item——SIHOO DORO C300 PRO V2 2026
A NEW ERA OF ADAPTIVE COMFORT
True comfort moves with you. This ergonomic chair supports your lower back immediately when you lean forward to type. When you lean back to think, the chair perfectly follows the curvature of your spine. The C300 Pro V2's DynaCore Full-Body Support – a system designed to move with you – responds to every movement, ensuring you stay supported and focused. No more fidgeting – just seamless comfort from your first cup of coffee to your last email.
LESS PRESSURE, LESS FATIGUE
Experience a larger contact surface that distributes pressure evenly across your back. The SynchroFlex backrest molds directly to your unique spine, adapting to your specific curvature for a perfect fit. This floating feeling takes pressure off your spine, making long periods of sitting feel much more pleasant. You can work or game on this comfortable ergonomic chair without that heavy, tired feeling at the end of the day.
STAY SUPPORTED, STAY FOCUSED
When your back feels good, you can think better. The self-adjusting lumbar support 2.0 works like a second pair of hands, intelligently embracing your lower back in real time. Whether you're leaning, twisting, or slouching, the support automatically fills the gap and follows every movement, keeping your spine in a natural, pain-free curve. You won't be distracted by pain, allowing you to fully concentrate on your work or game from morning until night.
UPPER BODY CUSTOMIZATION
This office chair is easy to adjust, making it feel like it was made just for you. Ensure this chair fits you perfectly. The 3D super-wide headrest has a 28% larger surface area to support your neck from any angle, providing full support and no strain. Combined with the 8D bionic armrests, it relieves tension in your shoulders and supports your arms, whether you are gaming, typing, or relaxing.
SEAMLESS ADJUSTMENT WITH SMART GRAVITY RESPONSE
All essential adjustments — height, backrest, and seat depth — are easily reached via the right-side lever, without needing to bend down or fiddle. The Smart Adaptive Mechanism 2.0 automatically adjusts the backrest resistance to your weight and locks at 105°, 125°, or 135° for work or rest. Adjust the seat depth to perfectly match your leg length, relieving pressure on your thighs and promoting blood circulation. This office chair feels like it was made especially for you.
