The chairs appear to have been reassembled, with certain elements having been replaced or restored.
Chair 1: The chair has most likely been reassembled in the past, leaving glue residue at the joints. It has since been properly restored, but visible traces of the restoration remain (see photo). The square rattan seat has been reinforced to make it more durable and structurally stronger.
Chair 2: The chair has been reassembled in a similar manner and is in a less stable condition than Chair 1. Missing parts have been replaced (see photos). The most significant restoration is the horseshoe-shaped back, which was broken and has been reattached. The woven mat seat shows some staining.
