Sturdy and Easy to Move
Color: Black, Size: 132"- 6 Panel
This 6 ft black partition on wheels is exactly what I needed to divide space without sacrificing style or stability. It’s sleek, professional-looking, and blends in well with any environment—from office spaces to home studios.
The build quality is impressive—very sturdy and doesn’t wobble at all once it’s in place. The wheels glide smoothly and lock securely, making it easy to reposition or keep stationary as needed. Assembly was quick and straightforward, with all parts clearly labeled.
Overall, this partition is a perfect combination of functionality and design. Highly recommend it if you need a durable, mobile room divider that looks great and performs even better.

Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!

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.
