This set of floating shelves was a disappointment. They’re advertised as holding 20 pounds, but mine began to bend with barely 10 pounds on them. All the screws and anchors were installed tightly and correctly, yet the metal brackets still warped under minimal weight. The shelves look fine on the wall, but I’m leaving them up only because I don’t want to patch a dozen holes—not because they’re sturdy. Definitely not the quality or strength I expected.

Clean look and very sturdy

Color: Brown, Number Of Shelves: 2, Size: 36"W x 6.5"D

These floating shelves look great and were easy to install. The invisible brackets give them a clean, modern look, and they feel sturdy once mounted. Perfect for adding storage or décor in a bathroom, living room, or bedroom. Great quality for the price.
