Very sturdy!
Size: 31.5 Inch, Color: Rustic Brown
I absolutely love these shelves. They were easy to put together and hang up and they look fantastic. I ended up having to use extra boards to screw it to the wall just because of the location of the wall stud, but you can't notice it at all, really. They are pretty big , the picture doesn't do it justice. I'm very pleased with this purchase.

Beautiful Shelves.
Color: Brown, Size: 3Tier48in, Color: Brown, Size: 3Tier48in
Did not come with instructions but easy to assemble once you start putting together. Very sturdy and well made, real wood shelves, not too heavy but can definitely hold a decent amount of weight. The shelves themselves are rough (could have been sanded better) but where it’s for decor and not every day use, no one would ever know. I love it.
