The shelving unit arrived in two large boxes. The instructions were clear and all the material to set up the unit was included. Assembling the unit was a two person job, yet very simple. 

In general, the shelving unit looks nice, but I don't know if I would pay $800+ if I had to do it again. It does have a VERY strong chemical odor that gave both my husband and son head and stomach aches in the time it took them to assemble the unit. The day after assembly, the open 13X13 room housing the shelving, smells of chemical and the odor is noticeable from the entry and dining room. I am sure, in time, the odor will dissipate. Unfortunately for me, we are having a heat wave and windows cannot be opened.
