Chiavari chairs are typically manufactured from four main materials: Solid Wood (Beech or Locust), Resin (Polycarbonate), Aluminum, and Steel. Solid wood is the traditional choice, offering a classic aesthetic but requiring more maintenance; Resin is highly durable, waterproof, and ideal for outdoor events as it is often 'color-through' (scratches don't show); Aluminum is the most expensive due to its lightweight nature and rust resistance, making it perfect for high-end rental markets. Steel is the most budget-friendly option but is prone to rusting if the powder coating is damaged.
