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."

Very useful
Color: Black
I’ve been using this room divider to separate my space from my daughter’s, and it has worked out really well. It provides just the right amount of privacy while still keeping the room feeling open and comfortable. The design is simple yet stylish, so it blends nicely with our decor. It’s also lightweight and easy to move when needed, which is a big plus. The material feels durable and well-made, not flimsy at all. Overall, it’s a practical and attractive solution for shared spaces, and I’m very happy with this purchase. I would definitely recommend it to others.

Great Room Divider
Color: Black
This product is a great room divider that decent quality and worth the price tag. The look is sleek and fits seamlessly into any room without complaint. The assembly was easy to follow and the quality is long lasting. Not only that, I need it as my sons share a room and we’re looking for some privacy. The divider is able to extend across a decently large area really divide the room as it has 4 panels. Overall, this is a great product for its cost and if your looking for a room divider that’s not too costly, this is the pick.
