Great for separation and stands on its on without issues.
Color: Midnight
Nice panel! But ... if you plan to use as a bulletin board, not great. We are going to place styrofoam in between to see if can get things to stay in place. We homeschool and it keeps our grands from distracting each other.

Provides privacy without being stanoffish
Color: Steel, Color: Steel
Its a perfect way to get a lil bit of privacy, its the color steel. Its a little darker than the picture but it works. Free standing doesn't attach to furniture and takes maybe 10 mins to put together. It's about 5 feet tall. Very lightweight cover slides over the steel frame and zips st the bottom.

Perfect for my office space!!
It's a well packaged item including a simple tool set and a clear instruction. I put it together just by myself in about 15-20 minutes without any problems. The base is solid pieces of metal, and it stands very sturdy. It's also light enough for me to move it around in my office to serve different purposes.
I like the color and the quality of the fabric. It blends in with my office space perfectly. I needed it as a partition between my desk and the door, and the background for my video conference call. Surprisingly, it can also deflect the air coming down from the AC vent behind my desk. I didn't expect it to 100% soundproofing (not its purpose), but I feel it did absorb some humming sound from my mini fridge behind my desk.
I would recommend this to my colleague.
