I bought these 12-inch deep floating shelves for my son’s room and they turned out great. The extra depth makes a big difference compared to standard floating shelves. He’s able to fit books, trophies, and some of his collectibles on them without everything feeling cramped. The shelves feel sturdy and well made once installed. The hardware that came with them worked well, and they sit flush against the wall which gives that nice clean floating look. They really helped add storage while also making the room look more organized and put together. I added lights underneath which I also bought here on Amazon... I also like that they’re deep enough to actually be functional, not just decorative. My son is using them every day and they’re holding up really well. Overall I’m very happy with this purchase and would definitely buy them again for another room.

Good looking shelves

These shelves turned out perfect for my bedroom project! I read lots of reviews about people having trouble with the wall anchors not holding up, but I’m going to equate that to user error. I had no trouble installing these and even took a couple shortcuts. I only used two wall anchors per shelf, but also pre checked the holes for studs. I used one dry wall screw per shelf as well. Knowing how wall anchors can be, I used one drill bit size smaller than the directions suggested. They said use 1/4, but I used 15/64. Probably could have gotten away with one smaller than that at 7/32. With all screws, I made sure not to press too hard into the wall and just turn the screw. That helps the anchors and threads stay snug in the dry wall. There was only one shelf that came out feeling a little saggy, but I think it’s because the holes in the shelf are not quite right. However, it still holds strong and no problem with a box of shoes on it. All this being said, I pre weighed my shoe boxes and knew I only needed to hold about 5-7 lbs. I was super detailed with measuring the bracket spots to make sure everything was spaced and leveled appropriately. The wood on the shelves does feel a little cheap, but it looks great so I couldn’t care less. I would purchase these shelves again and might have to as my display collection continues to grow.

Easy install, wide and sturdy

I put these shelves in a strange little cubby that was created in my kitchen by removing the sad excuse for a pantry that was once there. Super easy to hang, I’ve only hung two here and have other plans for the 3rd one. Good purchase for sure. Very sturdy and look expensive, without the high cost.

Great shelves!

Size: 12"D x 35.4"W, Color: Black

These were perfect for what I needed & easy to install with included hardware; looks great and looks like quality item. I like that they will hold 20 lbs so I can change what I place on them with no worries.
