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

Nice divider. Set up is a bear. I am a bit concerned with stability. Overall I like it.

Great privacy room divider
Color: Black, Size: 6 Panel, Color: Black, Size: 6 Panel
I got this room divider for our game room that shares the garage/laundry room, to separate the spaces. I was happy that it was relatively easy to put together in less than an hour with nothing more than a screwdriver (provided) although I used a small handheld drill. The instructions were pretty straightforward and easy to understand as everything was labeled. I have 2 small grandkids at home running around while I put this together so my timeline to completion might be longer than others. It recommends 2 people to assemble, but I was able to complete alone in about 40 minutes total and as I said I used a small handheld drill, (although it does come with a small Philips screwdriver) which is the only tool you need for assembly. The first two panels took me about 20 minutes but the other 4 were simple repeats after the initial 2. After all 6 panels were assembled the plastic clips to piece them together were literally a "SNAP" to put on. The poles are made of metal and the panels are made of a very sturdy almost canvas like fabric. When held up to the light not a lot shined through so very good for privacy. You can snap them together in sections and have 2 separate panels of 3 or what ever configuration you want. They are easy to move and bend around furniture or other obstacles, also fold flat together if you need to put them aside for storage. This worked out just as we had planned, very easy to move around when needed and I am very happy with this product. I loved how simple it was to put together, easy instructions, and the durability and functionality of it.
