      Cute backdrop for videos and room separation
      Color: Black
      Bought this because sometimes you need emotional boundaries AND physical ones. Surprisingly sturdy, looks nice on camera, and makes a room feel more peaceful instantly. Side note I have 2 cats and 2 large dogs and it has took a couple of beatings but did not damage at all!

      Transforming Space: A Tale of Two Stunning Room Dividers
      Color: Black, Color: Black
      The four-panel screen room divider is absolutely stunning! Unfortunately, the first one the FedEx driver delivered ended up at the wrong address. After notifying Amazon, they promptly sent me a “replacement” room divider through UPS, which arrived right on schedule. Now, I find myself with two beautiful dividers! They both enhance the aesthetic of my home. I informed Amazon that my first room divider magically appeared today in my building’s lobby. I’ve placed one of the new screen dividers in front of an old one, and the modern Roundhill divider really makes my older piece look outdated! The Roundhill screen divider is sleek, bold, and refreshing—I’m in love with it. The second divider serves a practical purpose by hiding my bulky grocery cart, fan, and vacuum cleaner. These items used to clutter my living room closet, making it difficult to access due to the abundance of coats I had stuffed in there. Now, all those items are neatly tucked away behind the elegant Roundhill four-panel screen divider, bringing a sense of order to my space. Thanks, Amazon! ♥️ Thanks, Roundhill! ♥️

      Beautiful, Sturdy, Well Made, good Value for the money
      Color: Black
      I don’t know what the bad reviews are about. This is a beautiful, well made 4 panel screen. The screen print appears to be a standard print that is likely the same on every screen they produce (not hand painted by two different people). It is beautiful. Everything about it, including the colors and the screen print image on rice paper, is more lovely than the photos. The wooden frame (black) is solid and sturdy. The hinges are stable and well positioned. When people say lightweight it sounds misleading. It is lightweight enough to easily maneuver but this four panel screen is sturdy and stable. It is slim and tall so someone could conceivably bump into it and jostle it. But no more so than any number of other items in one’s home. I highly recommend this beautiful, lovely, fine piece of home decor. I purchased this as a divider between my work station (office) and my living room. Also, even though there was a slight dent in the package when it was delivered, it wasn’t a deep enough gash to damage the screen. When I pulled the screen from the box my first thought was just how study it is. So very pleased with this purchase.

      Beautiful Room Divider
      Color: Black
      This room divider is so beautiful and elegant yet very functional, study and very well made! I have had many compliments on its beauty and elegance. They have said it is much nicer than blurring my background. Which affects how you look on a teleconferencing meeting. I do zoom meetings at times for my religious meetings when I cannot go in person! And this is exactly what I have needed to obscure my private bedroom space. The size is perfect for my size desk. It covers completely the whole area not showing any of my bedroom to the public. When not in use I fold it up and put it away. It is lightweight and very easy to move around. The height doesn’t make it awkward to move and yet tall enough to obscure my whole background. MORE IMPORTANTLY~NO ASSEMBLY NECESSARY ‼️ You will not be at one moment disappointed by this purchase instead you will love it!💖💕💖
