The shelves themselves are very sturdy real wood (or at least look and feel like it). I love that the mounting brackets are one long bracket so that it’s easy to make sure it’s level. However, the instructions say that for best results, use the drywall anchors provided. But in actuality, for best results, take those out of the package and throw them in the trash because that is where they do their best work. Get yourself some good 30-50lb drywall anchors and use those with the screws that’s come with the shelves.
