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.

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.
