REVIEW AFTER A YEAR! People who are over six feet tall should not sit in this chair. A year later, the materials used for sheathing burst and tore all over the place. Seat, backrest, and armrests are included. I would strongly suggest looking in other places. Choose not to go with "eco-leather" at all costs! You should make your own decisions on the rest of the elements; for example, I recommend that you buy a chair yourself because, in the end, it should be comfortable for you; to determine whether or not a chair is comfortable for you, sit in it.
