We tried others that were nice but this particular room divider adds total privacy. We were looking for that. Easy to assemble. There is no gap if you position each petition close enough. The guality is very nice. Exactly what we were looking for.

Nice room divider!
Color: White, Size: 8 Panel
The white panels are a nice off-white color. shipped in perfect condition. Already assembled so set up was quick. We use them to separate a photo studio from the main entry. Easily covers a 6 Ft. opening to the room. They are a woven material with wood colored sticks to support the weave. They are about 6 Ft. tall at the top of the curved section but less at the hinged sections. Light and easy to set up and take down. We are straddling two different floors so the extended legs at the bottom make this easy. Not sure how to clean them but they look great so far!

Instant Privacy
Color: Beige, Size: 8 Panel
Bought this to separate a ground level living area used as an office. Works well to cover visual clutter; allows a clean look when entering the front door. Comes fully assembled. Hinges are sturdy enough, as long as the panels aren’t stretched too far; have to allow some bend between them. For the price point, quality and functionality are satisfactory.
