The Bottom Line
The SIHOO Doro C300 delivers where it counts for long desk days: adaptive lumbar support, breathable mesh, and safety-tested build quality. Just know the armrests won’t support your weight when you stand, and taller users may find the lumbar sits too low. For average-height users who sit all day, it’s a strong, comfortable pick.
