The Frassie 25-Inch Heavy Duty Office Chair Base is a mechanical foundation utilizing reinforced polymer injection molding. Technical data indicates a standard 50mm (2-inch) center hub diameter, compatible with Class 3 and Class 4 gas cylinders. The 25-inch diameter conforms to standard executive chair specifications, with internal ribbing designed to support static loads of approximately 350-400 lbs.
Material analysis confirms the use of non-corrosive nylon, which prevents oxidation in high-humidity environments. The base features five 11mm x 22mm sockets for universal caster integration. Textured finishing on the leg surfaces is provided to reduce foot-slip during use. However, the nylon construction does not offer the absolute rigidity of aluminum alloy frames and may exhibit scuffing from hard-soled footwear.
Structural integrity is maintained through the reinforcement ribbing, though the 25-inch footprint provides less tip-over resistance than 28-inch professional-grade bases. Proper mechanical alignment during cylinder installation is required to prevent socket widening and subsequent lateral shear.
The Frassie 25-inch base is suggested for users seeking a lightweight, corrosion-resistant replacement for standard-sized task chairs.
This component is found in the custom chair components category for furniture maintenance and repair.
