The two intricately carved wooden thrones date from the reign of King Rama I. The lower, square throne in front is the Phra Racha Bunlang which has gilded garudas and devas surrounding the base. It is surmounted with a nine-tiered white umbrella on the occasion of the Grand Audience. The Phuttan Kanchanasinghat throne is topped with boat-shaped Busabok Maha Mala Chakraphat Phiman throne, which elaborately gilded and decorated with glass mosaic, rests on a gilded masonry dais surrounded by wooden deva figures. Four pillars support the superstructure of the throne. The elevated dais, which was constructed by King Rama III, represents Mount Meru. The top level is decorated with garuda holding naga.
