No.
Color: Coal Black, Color: Coal Black
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

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.

Beautiful room dividers! I'm glad I bought several.
Color: Light Beige, Size: 6-Panel
This room divider is perfect for my use. I bought one with 6 panels and another with 4 panels, mostly to hide areas of my living space when guests come over. The screens are attractive, a pleasing color, just the right height and width, and a very pretty design. They require no assembly and are easy to put in place. When not in use, they store in a compact fashion. The only drawback is the odor from the manufacturing process. I left the screens on an enclosed porch with the windows open for about two weeks before I could tolerate the odor inside the house. After that, there was no problem.
