Equipped with 4 universal wheels, it is flexible in steering and can be easily placed in any corner of the living room, bedroom, or study. It is also equipped with a brake device, which can be firmly fixed with simple operation to eliminate the risk of displacement. The thickened base greatly enhances the overall stability. On the one hand, the stable base ensures that the bookshelf can remain stable when carrying a large number of books, eliminating the risk of shaking; on the other hand, when moving the bookshelf, it will not fall over due to unstable center of gravity. As an adapter for small spaces, this rotating bookshelf can easily fit into the narrow corners of bedrooms and living rooms, making the most of limited space and injecting vitality into small spaces.
