This is built to last--great quality.  Love the ability to install just the parts you want to achieve the look you like, although I don't think the listing made it clear that this would work in any of the three styles shown. Installation took about and hour and at times required two people because of the weight, but the job was not difficult and all parts needed were included. We had planned to put up just the shelf, but decided to go with the corbels and arch, and we're not sorry.  Another win for the Wayfair team!
