This photograph is a good example of a traditional uweni from the Tuapurie community, where the chairs are made with a more elaborate back. The uweni, often referred to in the literature as the 'shaman's chair,' is used by persons of religious and political authority, but is not exclusive to them. It is strong and usually lasts for generations if it is well made of the right materials and is not abused. The back of the uweni is supported by two legs that are reinforced by a sturdy cross frame that is tied and then glued with the native plant mixture called kuetsukuai. The preferable wood for the frame of the chair is brazilwood, itzate, used in combination with mature Mexican bamboo or otate, hakute. The woven otate seat is adjusted using pieces of otate twisted together and then tied with a leather rope. The backrest is made with pieces of otate that have been debarked so that they can be twisted without breaking them.
Two different native plants are individually ground, burned, and then combined with the ashes to make a sticky substance, called kuetsukuai, which is used to reinforce the chair and fix the decorative backrest. These two plants must be ground when they are mature or they do not produce a strong enough adhesive.
