Great value, perfect for our infant room!
Color: Black, Size: Standard - 4 Panel
Great product, sturdy design and easy to build! It is a fairly light weight item, which aids in the maneuverability of the divider. The color was as described and is dark enough to block the light from our sleeping infants! I do love that you are able to see through the slats and see the child sleeping- if you are looking for something with MORE privacy, this is not it. It has great coverage area and is dark and a wonderful value for the price, however, you are able to see through the areas where each panel connects!

Don’t waste your money or time!
Color: White, Size: Standard - 4 Panel
Don’t waste your money. The instructions make no sense and the metal poles are either sized wrong for the product or screw holes are incorrectly placed, but no two poles matched in size and placement making it impossible to put this together without the panels being warped. No matter how I tried to switch the poles to see if I had them wrong, they always turned out warped and incorrectly fit. I finally gave up and threw everything out - I wasted $50 on this junk and because I didn’t try to put it together immediately after I bought it, it is way too late for a refund. Lesson learned!

Sturdiness
Color: Black, Size: Standard - 4 Panel
Not so sturdy. It worked well for its intended job, but, it has to be secured to the floor for long term use.

Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.
