Key features of the Sihoo B300 Pro
Adaptive 4D MicroFit Lumbar Support
Sihoo's 4D MicroFit lumbar support system offers 50mm of height adjustment, 20mm of depth adjustment, forward-and-back movement and lateral tilt to help users customize support as their sitting position changes. The system is designed to stay aligned with your lower back across multiple sitting positions.
6D All-Around Armrests
The B300 Pro's 6D armrests are designed for more than standard height adjustment. They move vertically, forward and backward, inward and outward, rotate and flip upward when not in use. This means users can position their arms more naturally whether they're typing at a desk, reading, using a phone or gaming for extended periods.
Adjustable Backrest & Intelligent Recline System
Finding the right chair fit can be challenging, particularly in households or workspaces shared by multiple people. The B300 Pro addresses that with a multi-level backrest height adjustment range of 5.5cm and a three-level seat-depth adjustment range of 5cm. The adjustments help users tailor support to their torso length and leg positioning. The chair's intelligent recline system also automatically adjusts tension based on user weight, eliminating the need for manual recline tuning. The B300 Pro supports three primary recline positions:
- 105 degrees for focused work
- 120 degrees for relaxed activities
- Up to 135 degrees for deeper relaxation (with a footrest-equipped model)
Premium Breathable Mesh
For anyone avoiding heat buildup during long work or gaming sessions, the B300 Pro uses a premium breathable mesh material throughout the chair. Designed to promote airflow and elasticity, it provides a more comfortable yet supportive experience.
