Our California Crafted Mission Spindle Bookcases are built to last. We first built these Solid Oak bookcases in 1967 and haven't changed them. Solid Plain Cut Oak with Solid shelves and frame. These come in many sizes and all have flush sides to build a wall of bookcases. These are built using the design elements from Stickley, Roycroft and Charles Rene Macintosh. The design of this furniture creates a simple, yet elegant look. These are also high quality and budget-priced. No particle board, pressboard or MDF is used in these bookcases. They have adjustable shelves. They ship fully assembled.
