Paint Ready

Because the stair comes primed black, it’s ready to customize to the exact color you want to match the unique settings of your office. Or, if it already suits your décor, just leave it black as many often do.


Resting Platforms

If you need a stair that reaches a higher than average height, you might find a resting platform helpful or even required. This stair comes outfitted with a generous platform to make it easier to make the climb


One-Piece Look

Our proprietary continuous stacking tread sleeve approach for the center column allows you the convenience of a kit stair with the solid look and feel of a one-piece stair. So you’re left with a clean silhouette for your office.
