Not as tall as anticipated
Color: Black, Size: Wheel-6 Panel
Definitely not 6 feet tall, more like 5 1/2. Very sturdy and the fabric is thick. Works well for what we're using it for.

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well.
Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely.
One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs.
The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers.
Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster.
Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality.
Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.

Stable, flexible in deployment configuration, creates true privacy and looks great.
Size: 3 Panel 12FT W
This is the second room divider panel I have installed, and there are several features about this one that I like much better than my older one.
The fact that there are no gaps and that the material is thicker means you get more privacy or more hiding power, if you wish. My older divider has vertical spaces between each of the panels and the panels are half as wide as the Siebwin panels, so there are many vertical spaces. The Siebwin divider really creates privacy.
Another feature that I really appreciate is that the legs are wider and stand off from the floor. On my older one the legs are flat and they're rather awkward to adjust because they create more drag on the floor. The feet on the older one also loosen if you turn them counter clockwise, so adjustments of configuration that require the feet to be moved are more complex.
The older divider also must be deployed in a zig-zag fashion because he feet are not as wide, but this new one can be deployed and stable in a straight, an "N" shape or an arc. They are both the same length, but because the older one must be use in a zig-zag deployment it doesn't reach to the length of the new one.
The Siebwin divider definitely costs more at $103.48, but it sports several features and advantages over the other brand, so it does a better job and is worth the extra cost.
