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.

Good price

Pretty good for the price. We move them around a lot and use them as a room divider in school. It gets roughed up and has held pretty well. Needs to be tuned up by tightening all the screws or will fall apart.

Not sturdy but does the job.

Bought this to block an electrical panel in a room. Fabric is good. Frame is good but not sturdy. Pipes would not connect without strong force and once assembled, frame bends and can easily topple over.
