Bistro chairs come in all types and styles, constructed of almost every imaginable type of material. At the present time, cast iron bistro chairs for outdoor use are very much in vogue. These usually are sold as a set with a matching cast iron table. The tables are actually a knockoff of the familiar British pub table with its heavy cast iron base and marble top. The original bistro chair, as designed in the late 1870s by Michael Thonet, was made of thin wood and featured a caned seat bottom.
Present versions of that same chair are almost identical, although materials made for construction range from flat wood to molded plastic. Very often bistro chairs are created using bent aluminum tubing. Inexpensive bistro furniture made with brightly colored molded plastic is also perfect for outdoor events. These have taken the place of the familiar folding chair based on their light weight and ability be stacked one on the other. Of course these are not suitable for actual restaurant use and should never be used in replacement of high quality restaurant grade chairs.
