This bookcase is perfect and just what I needed for my living room. I have it vertical in my room. I am not sure why the picture would suggest it be used horizontal. This is great to display my treasures from all my travels. It is so pleasing to have the variety of shelves and heights rather than a standard bookcase. I have received many compliments. Also, it was very easy to put together. The instructions were simple and easy to follow. Just be sure to lay out the pieces first and go step-by-step. Simple for one person to put together in less than an hour. Amazing value for the price.
