A STEEL ROCKING CHAIR

The use of iron tube frames in the manufacture of chairs was developed around 1828 by the Parisian firm Gandillot & Cie and became widespread in Europe and America during the nineteenth century. A rocking chair of essentially the same design was shown by Winfield and Co. of Birmingham at the Great Exhibition of 1851 as part of a large display of metal furniture.
A similar chair is illustrated in D. Ostergard (ed.),Bentwood and Metal Furniture 1850 - 1946, New York, 1987, no. 11, p. 210-211.
