Great Value
Size: 4 Panels, Color: Grey, Size: 4 Panels, Color: Grey
These are great value and ideal for a divider that needs to be moved or maneuvered a small distance on a regular basis. Assembly is quick with a drill (don't over-tighten). Fabric seems of good quality and the unit seems sturdy expecially when linked together.

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.

Great for creating a workspace
Color: Grey
I needed a room divider that could be easily folded for storing to put behind my chair during my work calls. This works perfectly! Was very easy to put together. Lightweight but sturdy enough that it won’t fall over.

Base part of it
Color: Black
Even though I kept this it’s very uncomfortable because of the way the base works . They are very long at the bottom and it’s hard to open and close
