We threw it away
Color: Grey
This thing cannot stand on its own, the side bars bend since it is not sturdy enough to handle the material screens. After assembly, I was so mad at it, the pleasure of crushing it was better than returning it. I tryed to think of other ways to use it, but could not… i kept the screens, they are the strongest part of this thing. Very disappointing

Works well
Color: Beige
Does the trick for privacy and some noise blockage. This takes two people to put together. The construction make it easy to assemble, but makes it just as easy to come apart on its own.

I love this room divider! Was easy to put together. It's easy to move around. I also bought the eight panel. I move it and change it around all the time. Good color good material good privacy.

It works to divide a room, but it's not easy to use.
Color: Grey, Size: 6 Panel
This comes in multiple pieces and you have to build every single piece including the cloth that is between the two poles. There are plastic clips to hold the sections together, but they easily come off if you move the dividers the wrong way or try to reposition it. The only thing holding it up is rectangular shaped feet on the bottom and they are a pain when you hit it with your toes. It works if you need to divide a room, but its not pretty and there are far better options. It's cheaply made and has a habit of falling down if you are trying to use it in a straight or slightly angled line.

Nice divider
Color: Black, Size: 6 Panel
Nice divider. Set up is a bear. I am a bit concerned with stability. Overall I like it.
