We tried others that were nice but this particular room divider adds total privacy. We were looking for that. Easy to assemble. There is no gap if you position each petition close enough. The guality is very nice. Exactly what we were looking for.

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.
