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.

Not 6 ft
Color: Grey, Size: 34" - 3 Panel
I bought this for filming my auditions. I am 5’4” .The height lists is 6 ft but the fabric only reaches 5’9 1/2 “! when I must film myself head to toe, the top bars are showing. It’s easy to set up. But when I film I must tilt my camera to keep the top bars out of frame which is not acceptable.

Perfect for what I needed - getting a 2nd one.
Color: Black, Size: 22" - 4 Panel
Putting it together was a BEE-OTCH!! Yes, one of the tubes had the top cap installed at the wrong end (& getting it off required tools), and yes, stretching the fabric to get the screws in was incredibly hard...but am I buying another one? YES! After all is said and done, this is a great room divider. I opted out of installing the paddle feet & it still works perfect. It won't filter light all that great and even though it stands on its own, it can be blown over easily - but for the price? Excellent. If I wanted a heavy duty, thicker, more expensive one, I would've bought one. The 2nd one is on the way. Perfect height, no weird smell, nice and light and easy to move around.

WHERE HAVE YOU BEEN 😊
Color: Grey, Size: 34" - 3 Panel
I purchased RANTILA 3 Panel Room Divider, 6 Ft Tall Folding Privacy Screen Freestanding Room Partition Wall Dividers, 102''W x 20''D x 71''H, Grey. For outdoor use on my patio is perfect . PRIVACY!!! YAY! It was packaged very carefully. There were no missing parts. Instructions were there but I still had to use the video visually. A few screws would not screw in. So I used a hammer with a few good taps that helped using the screw driver. 😊 It was easy putting it together following the directions. Everything is well made. Love the height, functionality and it’s definitely light it works. Thank you
