Pretty and easy to put up.

Better built then expected. Easy to get out of box. Easy to put up. Not to heavy. I am 75 yo and this was easy.

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.
