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.
