Product Snapshot
Overview
The Sihoo Doro C300 Pro is designed to provide ergonomic support during extended desk use. This chair features a 300-pound weight capacity, BIFMA and TÜV safety certifications, 4D adjustable armrests, and a self-adaptive lumbar support system that adjusts automatically with body movement. The streamlined mesh backrest promotes airflow, while the waterfall-shaped seat aims to reduce pressure on thighs and hips during long sitting periods. The chair incorporates a weight-sensing mechanism that intends to create balanced reclining without manual adjustments and comes with a 3-year warranty coverage.
Consensus
our Verdict
The Sihoo Doro C300 Pro delivers exceptional ergonomic comfort with its self-adaptive lumbar support, breathable mesh design, and innovative 6D armrests. Supporting up to 300 pounds, it’s ideal for users facing 8+ hour workdays who need reliable back pain relief. While typically available for $399 (down from $699 MSRP), it offers adjustable seat depth (16.81″-17.76″), height (18.11″-22.32″), and a wide 20.28″ seat through an intuitive single-lever control system.
Main drawbacks include armrests that shift too easily without locking, a headrest too low for taller users (above 6′), and insufficient recline tension with no adjustment option. Despite these limitations, the C300 Pro represents excellent value for those seeking high-quality ergonomics at a mid-range price.
