Short answer: compare Sihoo chairs by seat fit, desk clearance, and the controls you will actually use; then check the current UK price and return route. The M18 and M57 are simpler starting points, the Doro C300 family adds a broader support and adjustment case, and the S300 and B300 Pro belong in the higher-spec comparison.How to choose a Sihoo chairStart with measurements: compare seat height, usable depth and width, armrest clearance, and the space beneath your desk.Choose controls for a reason: flip-up arms help with a tight desk; adjustable seat depth helps when a fixed seat is a borderline fit; extra recline controls matter only if you will use them.Match the exact version: names such as C300, C300 Pro, and C300 Pro V2 do not describe the same controls. Confirm the selected model and configuration before comparing prices.Where the B300 Pro fitsSihoo lists the B300 Pro in its performance chair range.
