I ordered the 36" shelf thinking it would be like other floating shelves I've bought: supported by a solid metal bracket with adequate anchoring into the sheetrock. And I believed it was "solid wood" as advertised.  Neither could be farther from the truth. The bracket that screws to the wall is soft pine rather than a steel bracket. Rickety. The unit itself is totally hollow and of very low quality.  All 6 of the anchors supplied failed to make adequate "purchase" within the sheetrock, so I put 2 additional screws into the studs inside the wall, but it's still barely supporting the items I chose to display.
