Technical specifications for the Shzond 28-Inch Swivel Chair Base describe a high-mass mechanical substrate designed for structural restoration. The 28-inch diameter provides a wider footprint than standard 24-inch OEM bases, which increases the center-of-gravity stability and reduces the risk of tipping during high-recline operations. The assembly consists of a reinforced steel plate/hub in a 5-leg star configuration with a matte black scuff-resistant finish.
Material analysis confirms a 2500lb static load rating for the steel geometry. Performance metrics indicate that signal fidelity depends on the central cylinder interface, which accommodates standard 17-50mm gas lift tapers. Included with the base are standard nylon dual-wheel casters with universal 11mm x 22mm sockets. These wheels are optimized for low-pile carpets but lack the acoustic dampening required for hard surfaces.
Installation requires a heavy rubber mallet to seat the gas cylinder into the central hub. Technical audits suggest the application of lithium grease to the cylinder taper before insertion to prevent mechanical creaking during swivel maneuvers.
This heavy-duty chair base is an appropriate alternative for oversized or "Big & Tall" seating systems requiring a stable mechanical foundation.
This product is classified under custom chair components as a primary load-bearing structural element.
