The chair is a mini one. Although it is not big, it sits really strong and solid. The joints are strongly fastened together, without using any iron nails but the bamboo-made nails. Oftentimes, the iron nails become corroded and the whole structure will be disrupted as time goes on. But, with the bamboo-made mails, such chair will last much, much longer.
See the video clip and know how the mini wood chair is completed. It really takes professional skills.
