Stands well on high-pile carpet
Color: Beige, Size: 5-panel
Great product! Stands up sturdy on my high-pile carpet. Not too heavy, not too light. It comes pre-assembled in a MASSIVE box, so just be aware. The condition was great, minus one spot that looks like the fabric weave was stained. Not noticeable. Kindof a pain to adjust, but that's not necessarily the fault of the product. Just a finnicky thing to get "just right."

Sturdy, Easy to Use, and Great for Privacy
Color: Black, Size: 88" W, Color: Black, Size: 88" W
This room divider is exactly what I needed! The metal frame feels very sturdy and stable, and the wider bases keep it from tipping over easily. The fabric provides great privacy and blocks light much better than expected. I also love how lightweight and foldable it is, making it easy to move around or store when not in use. Assembly was simple and only took a short time with the included instructions. Overall, it looks great, feels high quality, and works perfectly for creating a private space at home. Highly recommend!
