Divider
Color: Beige, Size: 4-panel
Looove this so much. No assembly needed just opened the box and it was ready. The quality feels okay, pretty sturdy and does its job. It’s very versatile i use it as a backdrop or a divider. It’s stable and a good value

Elegant with subtle tones
Color: Beige, Size: 5-panel
Well made, and rather elegant. It has more subtle tones in the weave than the picture can depict. Nice and lightweight so they are easy to move. Very lovely.

Pretty and useful
Color: Beige, Size: 6-panel
Bought this room divider as an alternative to installing a balcony shade and I'm so happy with it. It comes assembled and it's light to carry but stands firm once its placed. The bamboo material is a little sheer so the color gives the balcony a boho vibe. Very pretty way to block the sun and get some privacy.

Works very well, and good-looking
Color: Beige, Size: 6-panel
This is attractive and sturdy, and tall enough that my cat cannot get over it as long as there is no furniture nearby that she can launch herself from, which is why I got it. The bamboo is tightly woven, she can't get her nails into it. I installed some brass drawer pulls in strategic places so I can grab them to move the folding screens in different positions, depending on where I don't want my cat to go. So it gets moved around, dragged around, constantly and still looks in mint condition after almost 3 years of constant use. I highly recommend. The lightest version is very attractive.
