Assembly is harder than it should be; you get what you paid for
Color: Black, Size: 4 Panel-88''
Review of SUNALLY Room Divider 6FT Folding Privacy Screens, 4 Panel Fabric Divider for Room Separation, 88" W Freestanding Portable Wall Dividers Screen for Home Dorm Studio Office, Black
I hate when I have to leave products a not so good review...
Assembly is harder than it should be, mainly because there shouldn't BE any assembly. I have ordered several room divider privacy screens over the last couple of years and not one of them needed any kind of assembly. With that aside, it STILL was a pain in the sphincter to assemble. One of the "legs" just sits on top of a foot plate - it's not screwed in to anything.
It's kind of flimsy and the base plates don't have anything on them to not scuff up the floor.
With all that said, though, it does stand up and will block out what I need to block out. At the less-than-$50 price-point, it's kind of what should be expected. If I had purchased this outright, I would have considered sending it back and getting a higher quality. But if you only have $50 to spare and don't mind assembling things, it could be good for you.

Great buy
Color: Black, Size: 4 Panel-88''
This room divider is exactly what I needed. When you have 2 kids sharing a room and don’t want to spend a lot of money to divide their space this is what you can use. Believe it or not they are much happier now. This came in a small box which scared me but once I was able to get this up I was very pleased. It was easy to put together. The fabric is pretty good quality, it’s stable and stands up fine. Good value and worth it to have peace and quiet in the house.

Junk
Color: Black, Size: 4 Panel-88'', Color: Black, Size: 4 Panel-88''
Horrible. The parts are not right. It won’t fit together or disassemble and can’t return it like this. Parts won’t fit properly and missing holes for screws. Also, can’t get through to a person for any assistance. Picture shows the hole and then the lack of a hole where a screw belongs.

Great investment, and easy to assemble.
Color: Grey
Excellent dividers for the home. I purchased this set 3 years ago and recently had to place another order because the first order proved to be a perfect accessory in my basement apartment.
As previously mentioned, I am in a basement apartment, and with these dividers, I can take an open space and create compartments. After a while, you forget that that open space was once a single room. These options added a great deal to my "Fonshuay," and lifestyle. This is a great investment and it was easy to assemble.
