I just received this room divider and haven’t had a chance to set it up yet, but I’m already impressed. It’s much lighter than I expected — I was worried it would be bulky and unstable, but that doesn’t seem to be the case at all. It feels easy to handle and still solid enough for what I need. I plan to use it in my garage to section off a small workspace, and it looks like it’s going to work perfectly!
