Know before you buy
The lumbar support is designed to move with your body, providing constant pressure and alignment as you shift positions throughout the day. It automatically adjusts to your lower back's curvature to ensure consistent support without requiring manual tweaks.
Yes, the 3D armrests are synchronized to move with the backrest. As you recline up to 130 degrees, the armrests adjust their angle to maintain support for your forearms in any position.
The SIHOO C300 is built to support a maximum weight capacity of 300 pounds. It is BIFMA and TUV certified, ensuring it meets rigorous safety and durability standards for daily use.
The backrest features four distinct height levels. This allows you to align the lumbar support and back frame precisely with your spine length for a more customized fit.
Yes, the breathable mesh is designed to promote airflow, which helps regulate body temperature and prevents heat buildup during extended work sessions. It provides a firm, supportive feel compared to traditional foam cushions.
The intelligent gravity mechanism uses your body weight to provide a smooth, balanced recline. It allows you to rock back comfortably with adjustable resilience, ensuring the chair feels stable and controlled rather than loose or jerky.
