        Nice, large room divider for privacy
        Color: Black, Size: 1 Large Panel
        Easy to assemble. Fabric screen covers the large frame very well and provides privacy by separating spaces. I would not exactly call it sturdy, but it does the job and stands freely with no problem. It’s lightweight and portable if you need to move it. Came with a screwdriver and wrench tool for assembly.

        Solid divider
        Color: Black, Size: 1 Large Panel
        Easy to assemble, is not see through and seems sturdy. The optional wheels are a nice touch.

        Perfect solution
        Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
        Was a perfect solution to blocking off a part of a room for guest stay. My only wish was a bag for it to go in while not in use. Right now we’ve got it tucked away in a corner where it’s waiting to be used again. I put one wheel through a wooden partition gate (for dogs) and pushed a couch up against it and it held great keeping young kids out of the room. Though the dog figured it out pretty quickly haha I love the fabric in between the sections as well as the fact that they can be completely separate for individual use as needed. Makes it very useful in more scenarios.

        Great Divider, bad instructions
        Color: Black, Size: 1 Large Panel
        Happy with this as a room divider. Good price point and sturdy. I suggest skipping the directions and using common sense! The steps are made complicated when they are not ... and if you follow the directions you will have to go back and fix the skipped step of inserting the rods into the screen BEFORE securing the frame. Would buy again.
