YOWOS Circinus Core 360° Rotating Storage Rack Wood Walnut 2 Tiers

The bookshelf is easy to put together with a clear (to me) manual. It is sturdy, and the swivel is smooth. I have a total of 45 books on it, individual shelves either having 5, 6, or 7 books. I have the whole of Tamora Pierce's writing (US editions, mostly paperback with a few hardbacks), 2 special editions of the entire Percy Jackson and the Olympians series (both US hardbacks, both editions have their own shelves that they fit great into) and a shelf for my current reads/a journal. Each shelf seems to have ~6 1/4" width, 11.5" height, 8 3/4" depth at the longest point, 6" depth at the shortest point.
