These are the terrible. They keep falling down. The bottom part doesn't stay tight so it keeps turning making it in possible to stay standing. Its the absolute worst!

Decent value for the money.
Size: 6FT*6FT, Color: Grey
Was easy to assemble. Instructions were clear. Tools were supplied. It really needs to be assembled wherever you're going to be putting it as it can come apart easily when moved. The cross bars simply fit into open ended plastic 90 degree female ends. Overall for the money and to just have some division in a room it's a good value.
