These shelves are poorly made. Not very sturdy. No wall anchors are supplied.
The back shelving boards do not line up with the pre drilled bolt holes on the frame, on either of the two shelves I got. Managed to flip the back boards upside down but they now have a big gap rather than the flush look like in the pictures and instructions. The hardware for the bolts is embedded in the shelves so cannot drill your own holes in the shelves to fix the issue. I don't have the tools to drill through the metal frame.
Some base boards also don't line up, less of an issue, but makes it less stable overall if everything isn't bolted down
Have been waiting a week for someone from Mighty Ape to reply.
