This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

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.
