I was sadly surprised at the poor quality of this bookcase as I have been very pleased with other bookcases that I have bought from Wayfair. The photo is deceptive in that what appears to be paneling in the back of the bookcase is a very thin piece of pressed wood. The cardboard packaging was sturdier than several of the pieces; and a piece of paper in the packaging even warned not to mistakenly throw out the "paneling."  We stopped half-way through constructing the bookcase as we needed to glue two areas that had split and clamp them to dry before proceeding. I bought two of these and will be returning at least one. I would return both but the hassle of dissembling it to ship it back may not be worth the effort.
