First the shelf itself is perfection. It is solid wood and beautiful. I ordered a shelf slightly too big for my space due to not being able to find something solid enough in a smaller size. I love the shelf. The issue is that the shelf needs to be hung in studs and with hardware that can hold its weight. I paid for professional install. Person came this morning. I thought marks on wall were crooked. He said he could adjust. Adjust meant removing the screw and placing it just above where it was. When he left shelf looked straight. As soon as I put weight on shelf, screw fell and shelf is crooked. Mayfair refused to help situation as they booked with Angie. I cannot get hold of Angie. Professional install is not professional at all.
