I had another (similar) bookcase in mind that I ran across on Pinterest which was $4,500.  Uh, yeah, no.  So I looked on Wayfair to find something comparable and I found these!  I ordered the set of three bookcases for my home office and am very happy with my purchase.  Assembly was very easy.  Most difficult part was getting the cabinet doors to align, but after taking breaks once in a while to "hydrate" myself, per the instructions, which were hilarious, I was able to complete the assebly and attach to the wall by myself.  *Note:  Instructions mention you need two people to lift the bookcases.  I don't follow directions very well.
