Solid bookcase. I will say I was happy to see that the materials were metal and real wood for the shelves (no plastic or MDF). It was easy to put together, however it is a heavy bookcase once it's set up. So if you need to move it, I'd suggest asking someone to help you. The reason I gave it 4 out of 5 stars is because it's made in China & the welding where the metal ends meet is "cheaply" done (see attached photo). However, for "accent" shelving I would recommend it.
