This extremely large Arts & Crafts revolving bookcase is of commercial grade. The solid oak frame revolves using a heavy duty cast iron system for ease in rotating. Revolving bookcases are great for placing in those odd corners and hold an amazing number of books. Notice how the sides are cleverly designed to graduate in depth allowing books of various widths to be stored. The 9” tall top shelf is completely open and will hold such items as newspapers, large folio books. Etc. The next 4 shelves graduate in depth from 5 ½” to 8 ½” on two sides. The height also graduates from 9” tall to 14” tall. The other two sides have removable rods allowing full depth to store books. Notice the simple applied wooden buttons on the 2 sides. The quality and construction are impressive. The revolving mechanism works smoothly. The finish appears original and is in excellent condition having a warm color and rich patina. This handsome piece would work well in any home or office.
