In a Mid-century modern style, this three-tiered lamp shade measures 18" at the largest diameter and is 12" tall. Fits a standard harp. Requires some assembly of tiers. (Note: Although assembly is very simple, it is a little fiddly. So, keep a handy person nearby.) Shown on "Perico" floor lamp in "Summer Nights" and "Terra Ceia" floor lamp in "White Heron." Does not include lamps in photos.
