You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

The snap to put them together.
Color: Coal Black
This came in handy in the foyer. I didn’t want to see the door from my couch. I must be weak found it hard to snap them together. I kept 2 my daughter took the other 2.

I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.

Great shelves at an even better price
Color: Brown, Size: 15.7in, Color: Brown, Size: 15.7in
These shelves are great quality. Easy to hang and come with all the hardware you need. No matter what type of wall you are hanging them on. Saved me a bunch of space. Gave me a place to place some of my books without having to take up floor space with a bookshelf. Light weight material with a durable quality. Stable for lots of things. Fits my space needs
