This bookcase is easy to assemble and took about 20 minutes to put together. The only issue is that the wood was splintered on the edges because the top layer is very thin. I had to use wood stain to cover up where it was splintered. You may want to anchor this bookcase to the wall or put heavy objects only on the bottom shelves as it can be easily tipped. Shelves are deep enough for very large books and the adjustable shelves make it easy to fit even the largest of your books.
