The description of these say the fabric is linen.  Its definitely a polyester linen-like fabric... not real linen.  It has a sheen.  These need to be assembled which takes about 15 mins.  They give you the wrench you need and isn't too difficult. There is a small gap in the piping between the seat and the back of the chair since they aren't pre-assembled which is noticeable to me although I am very particular.   The seat is also very hard, not soft at all.    They look pretty enough when assembled but I bought over others because I thought they were true linen so am disappointed.
