Sturdiness
Color: Black, Size: Standard - 4 Panel
Not so sturdy. It worked well for its intended job, but, it has to be secured to the floor for long term use.

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!
