I bought 4 chairs in the lighter brown color. They are extremely comfortable and well made. 
Though I wont remove a star, as it wasnt related to how well-made the chairs are, the box they came in was filled with tiny and very sharp metal particles, which got all over the living room and were getting stepped on. It might have been from the powder coated legs. 
Also, the chairs have to be put together in a certain way or it is extremely difficult and makes you think the netal needs to be bent to fit,  which is not the case.
