    Works great but lacking value
    Color: Nocturne
    It's a well packaged item including a simple tool set and a clear instruction. No smell. 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. Sturdy metal for free-standing, yet pretty light weight for easy assemble and to move around. Keeping it beside my desk to separate lounging and work area, and I could move it easily if I want a conference-call backdrop. I can tell some difference in the sound absorption, as my all-in-one space (kitchen, dining, work, living) area can sound loud at times, it does provide some damping effect. But I must say for the price I was expecting more. More solidity and weight. More privacy. It's just not very big for the price paid. A good price for two panels but this was just a single.

    High quality divider, but at a high cost
    Color: Nocturne
    So if you've ever been into an office setting you've likely encountered some variety of this divider. There's a bunch of good things about this product. -It's a nice size -There are great color options, went with Nocturne and no regrets with that -It's sturdy with a good base -Offers a bit of sound deadening The biggest drawback of this product is the cost. It's pricey for ONE divider. I'm sure it would make a great set, although for me it would fiscally irresponsible.
