WITH GLOBAL MATERIALS // All Cooper Preassembled Stairs are engineered and handcrafted to order at our manufacturing facility in Somerset, MA. When you choose a Cooper Preassembled Stair, not only are you guaranteed a safe and reliable stair that will add beauty to your home for years to come, you are also helping to employ local craftsmen and artisans.


5 YEAR WARRANTY // We take great pride in our workmanship and undertakes to manufacture the very best preassembled staircase product possible. This commitment to quality allows us to offer a 5 year warranty covering defects in material or workmanship.


THE DIFFERENCE IS IN THE DETAILS // Cooper Preassembled Stairs perform better because they are built better. For example, a pocket screw from riser into the tread ensures a tight connection without relying on glue. On the other side, a tongue and groove connection between the riser and tread creates a sure fit that virtually eliminates squeaks.


GLASS, CABLE, AND MORE // Today’s contemporary design trend demands untraditional stair building materials and designs that push the limits of engineering. We have a full line of stair options to meet the modern design aesthetic and the capability to engineer stairs that seem to defy gravity. We challenge you to dream big, you trust us to deliver.
