Very pleased with this purchase
Size: 88‘’Wide-4 Panel, Color: Grey
This is very easy to assemble, light weight, and does exactly what it is supposed to. I thought it would be a little bit taller, but it gets the job done.

Worked well to separate space!
Size: 132‘’Wide-6 Panel, Color: Grey
Did the job I needed. I created a hang out area in part of the basement for my pre-teen and wanted a little privacy/separation for the area. Not hard to put together and was to move around. I do wish the legs Ira on with the rollers didn’t jet out so far.. is quite a tripping hazard..

Perfect!
Size: 88‘’Wide-4 Panel, Color: Grey, Size: 88‘’Wide-4 Panel, Color: Grey
This is exactly what I was looking for. I created essentially a doorway into the pantry area I have in my basement. I had the bought a screen years ago that hid most of it but this completed it. I ordered the 4 panels, for the size, and created a "door" of out the two.
