I can't say enough about the quality of this panel system. The vertical sides of the panels have aluminum that acts like a sprocket when the panels are folded. This, along with the metal hinges keep the panels in alignment for years. (Most folding panel systems use the fabric as the hinge.)

Each panel has adjustable feet.
Note the hidden metal hinges. The fabric was cut away to show you the construction. There are 2 per panel. 

This photo is of a top and bottom panel. The arrows point to the metal hinges. The top section of panels is lifted into place and stacked using aligning pins. The display is then unfolded into the configuration desired. The pins are very large and easy to align.

The endcap unhooks and folds flat for shipping. It attaches separately so the panels are easier to lift and stack.

To the right is the alcove counter with the curved tabletop. It has a hinged door. The instruction booklet is very easy to follow and shows other options for the display.

The counter has sliding doors on the back side and an interior shelf.

A 10 foot panel display can be setup in any of these designs. The limiting factors would be the alcove counter and the length of the backlit header.
