Nice quality, looks brand new even with daily use! Worth it!
Size: 6 Panel, Color: White
I got the Rose Home 6 panel room divider folding privacy screen and I LOVE it. I use it every day - extending it out to both block the sun, provide a backdrop for my plant wall, use as a backdrop for zoom calls, create privacy at night in front of the big windows and clear doors, and make impromptu study privacy walls in the office. This 6-panel has been the GOAT! Even though the screen is made of a woven paper material, it is still going strong despite daily use and has NOT broken anywhere. The frame is taller than other folding screens I've purchased and this one is also heavier and sturdy. Additionally the hinges fold open in BOTH directions (some screens only fold open in 1 direction like a Z). I use the folding screens indoors, but they have no issue with the AC or fans for wind resistance indoors. Sometimes I use them to hide storage or junk in the corner and make the room look neater. I also have a different brand that is the same material but has 8 panels and I love them both. I got 2 others that were made from synthetic canvas webbing belt/leash fabric and those break so fast - I just had to throw 1 away. This one is worth the money, even after daily use, it looks brand new!

Already assembled!
Size: 8 Panel, Color: Natural
Came way sooner than the estimated delivery date and it looks awesome! Biggest plus is it came ALREADY ASSEMBLED! I was expecting self assembly but maybe that's on me for not reading the specifics. Hoping it's the right size for my new studio apartment. So far the look and functionality is 10/10

Light weight & Sturdy
Size: 6 Panel, Color: Dark Coffee
I am so pleased with them. My lanai gets morning sun and I am concerned about the UV rays fading the
fabric of my furniture No more having to cover each piece at night. The screens are great.
Thank YOU
