Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!

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.
