Twin Size Academie Bed Frame. The bed employs industrial materials and masterful finishing techniques, with their reproduction looking much like its early-20th-century French predecessor. It is crafted of iron and steel with cast rosettes at the joints. Includes a metal support system; requires a standard mattress and box spring and is sealed with a distressed, oxidized finish that lends the patina of age. The frame is in good overall condition with wear that is consistent with usage.
