Very Pleased with Room Divider
Size: 4 Panel, Color: Brown
This room divider is even better than I expected. It's sturdy but is lightweight enough that I could get the box up a flight of stairs with no problem whatsoever. It folds and unfolds easily and is very easy to move. And there's no assembly required! It really is woven and is quite attractive. The main reason I chose this item was price (although I did like the way it looked) and I got more for my money than I thought I would.

Works well
Size: 4 Panel, Color: Coal Black
i bought this for 3 reasons.
1. Privacy when changing so I don't have to lock dog out of room.
2. In case MIL comes over and wants to snoop. She won't be able to see my bedroom.
3. A nice backdrop to use when taking photos of the clothing I make.
This is perfect for me.
My only "complaint" is that it is not the most sturdy thing. I have to finagle it in a way that keeps it from falling over.
But for the price, it can't be beat!

Cheap and unstable
Size: 4 Panel, Color: Black, Size: 4 Panel, Color: Black
Although this has nothing to do with the product, it arrived a day later than previously stated. Making me have to create a makeshift room divider the day it was actually needed. When the product arrived it arrived in a box that showed no evidence of damage. Once opened, divider was found inside a plastic cover. Great protector for dust or scratching. The divider was fully assembled so there was nothing for me to do but remove it from packaging and use it where needed. After further inspection the divider was not only cheap and flimsy looking it was absolutely unstable. It would wobble and appears to have been assembled in a rush making some panels crooked. I noted significant damage to the bottom portion of some of the panels both front and back. It does not feel like an item worth the price. The color is as advertised and the product had no smell. The sizing was accurate.

Excellent privacy shade.
Color: Coal Black
This delivered on exactly what it promises. So happy with the quality for the value. The shades are a fabric, nylon like, that are attached with a pocket on one end and velcro that adheres around the bar on the other.
This was incredibly easy and straightforward to put together. Every piece was clearly labeled, coordinated with the instruction sheet, and fit perfectly. Honestly, I wasn’t planning to leave a review but I was so impressed by how clearly labeled and well explained the instructions were that I felt compelled to note it. Especially for anyone who doesn’t like putting things together, or is used to subpar instructions, this is leagues above the rest. It’s such a simple build anyway, but after buying so many things that barely fit as they should, this stands out.
It is lightweight and easy to move. Offers privacy when opened, then can be folded out of the way. It looks exactly as pictured. No complaints, it’s a solid item and worth the price.
