This room divider is exactly what I needed! The metal frame feels very sturdy and stable, and the wider bases keep it from tipping over easily. The fabric provides great privacy and blocks light much better than expected. I also love how lightweight and foldable it is, making it easy to move around or store when not in use. Assembly was simple and only took a short time with the included instructions. Overall, it looks great, feels high quality, and works perfectly for creating a private space at home. Highly recommend!

Not bad

Color: Grey, Size: 88" W

Claims to be non see through but you can, easy to assemble but instructions aren't good. Decent money value, quality is okay. Good fit, not very sturdy.

They bend easily and hard to keep up

Color: Black, Size: 88" W

To flimsy, they are see through, not at all what is pictured

Lighter Than Expected — Perfect for My Garage Workspace!

I just received this room divider and haven’t had a chance to set it up yet, but I’m already impressed. It’s much lighter than I expected — I was worried it would be bulky and unstable, but that doesn’t seem to be the case at all. It feels easy to handle and still solid enough for what I need. I plan to use it in my garage to section off a small workspace, and it looks like it’s going to work perfectly!
