The price of Chiavari chairs is primarily driven by the base material: Resin (Polycarbonate), Wood, or Metal (Aluminum/Steel). Resin chairs are often more expensive due to their high durability, UV resistance, and 'color-through' properties which hide scratches. Wood chairs offer a classic aesthetic but require more maintenance; ensure they use beech or acacia wood for structural integrity. Metal versions are cost-effective for high-traffic rental businesses but check for multi-layer powder coating to prevent chipping.
