Perfect & light weight divider
Color: Charcoal Gray, Size: 8 Panel
I really like this divider. I have it in my bedroom which is also where my "work from home office" is. The divider blocks my bedroom and dresser perfectly. It's very light weight and very easy to move.

Room Divider
Color: Beige, Size: 8 Panel
I received my 8 panel folding divider and realized that I probably should have just ordered the 6 panel one. But it is nice and sturdy and was already put together. I am very pleased with the product.

Great Dividers
Size: 6 Panel-120"W, Color: Beige
Love these!! Many uses. Simple, nice looking, sturdy overall. Well made.
Bought to divide the unsightly storage area from the calm rest area in the basement.
Also, these worked well for our garage party where the dividers let light and air in, though blocked the view of our party area from the cars driving by.

Just what I needed
Size: 4 Panel-136"W, Color: Black
I have a one bedroom apt and my son stays with me half the time. He has an air mattress in the living room until I can afford a 2 bedroom. But he’s in his early teens and needs privacy. I bought this after looking online at may of these. I’m so glad I went with this one. It covers his air mattress 3/4 of the way around and now he has his own little nook. I also gave him some led lamps and he might it like his own little nightclub. He LOVES it. And now he’s excited to be in his space. The quality is so good and there’s no see through, no gaps, it’s perfect.
