The stools are made of scented Lebanese cedar wood or American walnut and come into two different heights. The shape of the stools reminds of the characteristic thread of screws, basic elements for construction. The seat can be both slightly concave, this more ergonomically comfortable (standard version), and straight (available upon request). Any cracks or splits, before or after sale, are absolutely normal, being typical features of solid wood that, as it ages and becomes seasoned, moves according to the different conditions of the setting and humidity of the air. They can not be a reason for claims.
