This Book case is more solid and sturdier than another ladder bookcase that I have from another company. It takes the weight of more books much better than the other one. 

I like this bookcase a great deal and am happy with the purchase. I do have 2 complaints, though. The first is that it did not come with instructions for putting it together (though I figured if out with several tries as I was not familiar with one of the locking mechanisms). The second and more important is that the case does not stand without sliding and falling (while scratching the wall). I had to adhere rubber kitchen shelf liners across the bottom to keep it in place. I'm not sure if this is a one time issue that I simply had or if other consumers have had these problems as well.
