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.

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.
