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 investment, and easy to assemble.
Color: Grey
Excellent dividers for the home. I purchased this set 3 years ago and recently had to place another order because the first order proved to be a perfect accessory in my basement apartment. As previously mentioned, I am in a basement apartment, and with these dividers, I can take an open space and create compartments. After a while, you forget that that open space was once a single room. These options added a great deal to my "Fonshuay," and lifestyle. This is a great investment and it was easy to assemble.
