We were looking for a bookshelf to act as a open storage cabinet. The Mainstay we bought was just what we wanted. It was easy to assemble, looks very nice, and for a pre-cut, mass-produced unit, it is sturdy enough for our use. The cardboard back piece is the only part that isn't the quality you would find in a furniture store book shelf. Good product for the money. We would recommend it.

I bought a total of 4 bookcases easy to put together with minimum tools however if you don't line the backing up correctly you will have an issue with that however adding rods in lot the ones without the back should give it the sturdiness I'm looking for

The most wobbly shelf I have ever seen. Looks like it'll disintegrate if someone bumps into it. We aren't able to wall mount it since we're renting, though, so that might detract from the overall sturdiness. Regardless, it's difficult to imagine a single nail will do that much to keep it together.
