I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!

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!
