Easy and convenient way to block off space!
Color: Brown, Size: 4 Panel, Color: Brown, Size: 4 Panel
Turned part of my basement into a dressing room. Ordered several of these and they worked out perfectly. I was able to separate the “guest room” area as well as our gym! Kept my space neat and private. And no assembly!

Great visual barrier for home office
Color: Brown, Size: 4 Panel
This is going to work perfectly for me to create a visual barrier in my home office. No assembly required. Literally took it out of the box and stood it up on carpet. No concern that it will randomly fall over. Would buy again.

Good product. Wrong color!!
Color: Brown, Size: 6 Panel
The product is great but it's not as advertised. It's supposed to have bamboo-colored panels. The color of light bamboo. It has dark panels. Mahogany colored panels. Way too dark!!! Looks nothing like the picture on the website. Made a dark space even darker.

Light weight and large privacy screen
Color: Black, Color: Black
The privacy screen is light weight and of great quality. The screen can block sight and also is easy to set up. It screen is sturdy and stable. It is a cheap solution for separating paces in rooms. The privacy screen is of black color and good good in many places. It can be folded when not used and does not take much space for storage.
