SIHOO B100-PRO-M101-JT Gaming Chair with Footrest, 4D Armrests, 330 lb Capacity

Adaptive Lumbar Support

The SIHOO B100 PRO is a new gaming chair built with a metal frame and breathable mesh upholstery. It supports users up to 330 lb and features an adaptive dynamic sacral pillow combined with a dual-back design to maintain spinal alignment during long sessions. The chair swivels and offers three recline positions at 113, 123 and 133 degrees for varied postures.

Integrated Footrest and 4D Armrests

A retractable footrest deploys to create a relaxation zone when the backrest reclines to 135 degrees. The 4D flip-up armrests adjust in height, depth, angle and 360-degree rotation, then fold up to save space when not needed. An ultra-wide 3D headrest moves on two joints to match the neck curve, while the mesh material promotes airflow across the back and seat.

Dimensions and Weight Check

Verify that the 21.08-inch back height, 19.7-inch shoulder width and 19.7-inch waist width suit your body proportions before ordering. Ensure your floor area accommodates the five-wheel base and the extended footrest when deployed. The chair is rated for 300 lb under SGS and BIFMA certification, so confirm the 330 lb maximum aligns with your requirements.
