Great product
Size: 4 Panels, Color: Beige
We needed something too block off a corner of a room. I looked through a ton of different room divider options on Amazon. I’m glad I did. I’ve had it up for about up about 4 months now, and it’s holding up well. Not too difficult to put together you just got to pay attention and make sure you’re putting it together the right way. The fabric is of good quality. It doesn’t feel flimsy.

Decent room divider for a good price.
Size: 4 Panels, Color: Grey
Honestly I'm pretty happy with the product for the price paid. The instructions were relatively easy to figure out and I put it together myself in an afternoon. Looks good for how cheap it was, and does exactly what I wanted. Double check your measurements before buying, but this worked out great for me.

Great solution if you need some privacy!
Size: 6 Panels, Color: Beige
I had my family and relatives came over last holiday and I needed to provide a make shift rooms for them. I have a finished basement. I purchased 2 sets of VEVOR 6 Panel Room Divider and solved my problem.
The VEVOR 6 Panel Room Divider is a practical and affordable way to create privacy in any space. It’s easy to set up and the folding design makes it simple to adjust or store when not in use. The panels are lightweight but still feel sturdy enough. Assembly needs some extra patience
Overall, a great value option for flexible and convenient room separation. Highly recommended.
