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.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
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!
