Clean and functional
Color: Grey
This room divider is very functional and sturdy for a single-panel divider and stands securely without wobbling. The extra-thick material provides great privacy and helps visually separate the space.
The neutral grey color looks clean and modern, blending nicely with my décor. It was easy to set up right out of the box and didn’t require any complicated assembly. The height and width are perfect for creating a defined my home office space.

Not so good as expected.
Color: Grey
Pretty poor quality partition. It should hold up to normal indoor ware as long as to don’t touch it. If it is used in a garage (as I did) it will collapse.when subjected to any kind of a breeze at all. I had to reinforce the partition with cross-wires for added support and it was still not enough.

Functional but not attractive
Color: Black, Color: Black
I purchased this to hide my cats liter boxes as he refuses to use them unless they are on the finished side of our basement which is also my kids play room. This functions as I’d expect. It isn’t great to look at but better than cat boxes. Overall it might make a good backdrop if needed. My only complaint is the hex/allen wrench doesn’t fit in the screws provided. If you don’t have an alternative tool that’s a smaller hex it will be annoying to put together.
