Metamorphic Library ChairView progress: 1 | 2 | 3
  

This rare and unusual metamorphic library chair from the Regency period had extensive previous repairs that were now failing. When upright the chair functions as usual, but when it is turned over and released, stair steps form to reach the upper shelves of books. The back legs were split and detached, with one of the mortise and tenon joins drilled out. All the joins on the bottom half of the chair were glued with polyvinyl acetate adhesive on top of the original hide skin glue. These joins were also failing. The caned seat had obviously been replaced at least once, and it too was now ripped and torn along the back edge.

The bottom half of the chair was dismantled and all previous adhesives cleared from the joins. The damaged mortise and tenon join was reworked as a two-sided tenon. All splits were secured and reconstruction was with traditional hide glue, used both for its durability as well as its reversibility. The cane seat was rewoven and stained. All dents and scratches in the surface coating were filled and touched in to integrate the appearance. A final application of wax was applied overall and polished.
