This came in pieces wrapped is Styrofoam batting with a bag of bolts, washers, 3M squares, and an instruction sheet that left little to desired.
If you are a guy, you won't even bother looking at them. As for this gal, they weren't exactly helpful as the way the suggest was more awkward and I flipped the unit to make life easier when putting it together on the kitchen counter.
Hubby was impressed with my skill set but came back later to tighten the flange nuts. I appreciated his concern.
The bar that is supposed to hold a hanging plant is a nice idea but not recommended with what was included in the packaging.
I'm sorry, two squares of 3M tape will not pull the unit together and support a bar that needs to be screwed into place.
An adaption was made by us. As a team we pushed the towers closer to tap the panels to drill holes (which by the way are on the bar) but not on the shelves. A simple black screw works great but we'll be careful not to reach underneath as they are sharp.
The unit comes with 4 curved legs or 4 caster wheels with locks. We chose the wheels for easy mobility when cleaning the house. If you use the legs , I would suggest not dragging the unit loaded with plants across the floor as the plastic leg protectors are cheap and the framework might bend.
