The biggest highlight of this bookshelf is that it can be combined. It never looks monotonous because there are 4 types of bookcases instead of a single bookshelf combination. Put the 4 bookshelves together, it will look like a bookshelf wall, which looks more grand and elegant in the living room. The bookshelves can also be used as kitchen shelves and display cabinets. The combination bookcase set measures 13.8"D x 94.4" W x 71"H. The A bookshelf contains 2 doors and 2 glass doors. The B cabinet contains 4 doors. The C cabinet contains 2 doors and 3 large drawers. The D cabinet contains 2 glass doors and 3 large drawers. The storage cabinet is made of high-quality MDF and selected high-quality hardware accessories. The bookcase has strong load-bearing capacity, structural stability, and durability. The surface of this cabinet is finely polished, smooth, and easy to clean. It is also equipped with an Anti-toppling Device. This bookcase requires assembly.
