Assembly of the shelves was very easy and took less than an hour. The shelves are sturdy and well made.  I had been looking for something to fill a narrow space next to my desk in my home office.  Prior to buying this bookcase, I tried a tall potted plant and then a floor lamp to fill the space, neither looking quite right.  These shelves fit perfectly.  Please note that I ordered the ebonized acacia which was darker than I had expected - still looks great.  I am very happy with this purchase.
