When sourcing VIP seating, the structural integrity begins with the wood type. Prioritize kiln-dried hardwoods such as Oak, Walnut, or Beech, as they offer superior resistance to warping and cracking. For the finish, ensure the supplier uses eco-friendly, non-toxic lacquers (such as PU or water-based paints) that meet EN71-3 or ASTM standards for chemical safety. If the chair includes upholstery, the foam should be high-resilience (HR) flame-retardant foam with a density of at least 35kg/m³ to prevent sagging over time.
