Dimensions ..... height limitations .....
just semantics.

Semantics? How about common sense?
I was looking for book shelves a couple of months ago. Was searching online and reading reviews to see how a given shelf is, particularly how easy or difficult it is to assemble. I found this book shelf I really liked and available locally, but the reviews on how difficult it was and how long it took made me take a pause. People were saying stuff like "no directions", "can't figure it out", etc. Anyways, there were also a number of positive reviews, but without mention of easy of assembly. I ended up buying two.
Got them home and yeah, the directions are minimum. However, with just a LITTLE bit of common sense, it was pretty easy to figure out how to assemble. Yeah, better directions probably could have made it easier, but I had zero issues assembling them. I think people have become so used to people telling them exactly what to do that they have lost the ability to think for themselves and figure things out.
