Great Floating Shelves
Color: Oak, Size: 30W x 11.6D x 2H, 2 Pack
Really pleased with the look, feel and quality of these floating shelves. Installation was easier than I imagined and the size fit my space perfectly. And best part - affordable. Would recommend and buy again.

Cute and stylish
Color: Oak, Size: 24W x 11.6D x 2H, 2 Pack, Color: Oak, Size: 24W x 11.6D x 2H, 2 Pack
The shelves look super cute in my laundry closet redesign. Not heavy duty, but that’s okay for my purposes.

Shelf is nice, bracing is garbage.
Color: Black, Size: 35.6W x 11.6D x 2H, 2 Pack
Just like all the other reviews, it sags. Regardless of how its mounted to the wall, the bracing itself is weak. Shelf is nice though, definitely would have to get different brackets to make this worth it.

Decent shelf
Color: Walnut, Size: 35.6W x 11.6D x 2H, 2 Pack, Color: Walnut, Size: 35.6W x 11.6D x 2H, 2 Pack
They look great and come exactly as described. They were super easy to install and came with everything you need. Sizing is exactly as described. For the price they’re all around a great purchase. I bought these to mount under our tv for video game consoles and they are perfect.
However, they do not sit well on the wall. There’s only two mounting points when they should definitely have 3. We had to go get a shelf bracket from lowe’s to get it to sit right and not lean forward. So just beware if you want it to sit flush, you’re going to need something additional. Still worth it for the price!
