Static and fatigue performances of seat foundations of natural rattan chairs subjected to vertical loads were investigated. Static performance evaluation results indicated that rattan strip weaving patterns had significant effects on the vertical load-carrying capacity and stiffness performance of chair seat foundations. Herringbone-and grid-pattern woven seat foundations had significantly greater vertical load-carrying capacity than those made with a square-corner pattern. Square-corner-pattern seat foundations yielded a softer sitting surface than herringbone and grid patterns. Herringbone-and grid-pattern seat foundations provided firmer sitting feel and better deep down support for heavier sitters. The Burger model could be used to describe the force deflection time behavior of a rattan woven seat foundation subjected to vertical cyclic loading.
