Set up shelves and not sturdy at all. Followed the instructions perfectly. Very poorly made. I don’t have the box and now I’m stuck with the item. Garbage can here it comes.

There are better floating shelves
Color: Rustic Brwon, Size: 16in
Doesn’t feel very sturdy like other floating shelves I’ve bought, and they slant a little. The anchors and screws that it came with all broke so we had to get our own for it to feel more secure on the wall, but still feels wobbly. Overall, it looks good on the wall after the fact, but won’t be adding too much weight on it.

Very solid and nice looking
Color: Natural, Size: 72 Inch
Very solid. Mounting hardware is sturdy when you mount it into the studs of the wall. I weigh 180 lbs and I sat on it with no issue
