    Know what you're doing before you order
    Color: Grey
    There's a very high quality item easy to assemble last a long time it was pretty nice. For the first one. My roommate talked me into buying the second one and then he backed out of the deal he didn't have the money. So I returned it at the Amazon store and like a boomerang it came back. I end up having to buy it anyway you're still sitting in the box

    Must have for at home workers!
    I bought this divider because I work from home and wanted to have a professional and neutral background for video conferencing. There were other dividers that I contemplated purchasing because of the variety of colors but ultimately decided to go with this divider because of prime shipping. I noticed in the reviews of other dividers on Amazon a lot of people talked about cracks. I noticed a few cracks on mine but they are small and minimal in appearance so it does not bother me (see pictures). Overall, it came in great shape. I love the color of the divider. I was concerned it would come solid brown based on the pictures but it is more rustic, which I love. The dividers are tall and long so it covers a great amount of space. The hinges go either way which is also a plus. I will say it seems slightly unstable on carpet but it would only move if bumped into so that is not much of a concern. Most likely would be more sturdy on solid/ hardwood floors. Overall, I am super happy with my purchase. Definitely worth the price with fast 2 day prime shipping and no assembly needed.

    Game-Changer for My Space!
    Color: White, Size: 4 Panel Basic
    I recently purchased the Kecreque 4-Panel Room Divider, and it has completely transformed my living area. At 88" wide, it provides ample coverage, creating a private nook in my open-concept home. The white polyester fabric is not only sleek and modern but also wrinkle-resistant and easy to clean—just a quick wipe with a damp cloth, and it looks brand new. Assembly was a breeze; I had it set up in about 20 minutes. The metal frame feels sturdy and durable, and the three extra-wide metal feet offer excellent stability, ensuring it doesn't tip over easily. I love how the panels are connected with flexible buckles, allowing me to adjust the configuration to suit my needs—be it a straight line or an angled setup. This divider has been perfect for creating a dressing area in my bedroom, and I've also used it to section off a workspace in my living room. Its versatility is unmatched, and it folds down compactly when not in use, making storage hassle-free. If you're looking for a stylish, functional, and easy-to-use room divider, I highly recommend this one. It's been a fantastic addition to my home!
