I purchased this for my son's room and it fits very nicely in the corner.  It did come with a wall mount so that the shelves will not tip, but they are very stable so we didn't need to use it.  There is plenty of space on the shelves, but it doesn't take up too much room which makes them ideal for small spaces.  The shelves were very easy to put together in less than 10 minutes.  Would definitely recommend these shelves! 

Pros: Great value, easy to assemble, good quality
