What should I know about the swivel base and five-star base on an office chair?

Five-star base specification at OfficeFurniture2go.com follows load requirements. Standard commercial: reinforced nylon base (28-inch diameter minimum) for users up to 300 lbs. Premium commercial: polished aluminum base for executive chair applications. Heavy-duty: steel base (30-inch diameter) for 400+ lb rated chairs. Base diameter is often overlooked — a narrow-diameter base on a high-back chair is a tip-risk for heavy users. We specify base diameter and material as part of the complete chair specification.
