Sturdy, Easy to Use, and Great for Privacy
Color: Black, Size: 88" W, Color: Black, Size: 88" W
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
