We got 2 of the 58 inch 4 shelf bookcases and 5 white ,5 shelf bookcases...for our office ...they are a good quality...and they were so easy to put together..I was surprised at how the directions were very clear..I did it myself ...and I am a small womam....It recommended not using an electric drill but I used one.and it was even easier....the top piece tho that comes down from the top does need s Phillips screwdriver...but its still so easy....we left the backs off...and we will be using metal shelf pins..the plastic ones don't want to stay put.I highly recommend these bookcases..
