I priced and ordered these chairs under the impression they were real genuine authentic "leather." The last time I checked, the material on these chairs was called "vinyl." Beware of the word "bicast" in front of the word. leather. I guess it means "man made?" Otherwise the chairs are nice looking and comfortable. They take about 45 minutes to assemble from the time you open the box to the time you get to sit in them. All assembly is via hex screws and the hex wrench is included in each box. I could have purchased vinyl chairs at a lower price.
