Denver 41" Spiral Stair Kit | Compact Wood Indoor Spiral
The Denver 41" Spiral Stair Kit brings together the warmth of solid wood and the strength of powder-coated steel in the most compact diameter of the Denver line. At 41" (105 cm), this Italian-designed indoor spiral staircase features solid beech wood treads with Finger Joint technology and a non-toxic, water-based three-layer finish for lasting beauty.
Built for tight spaces, the Denver 41" requires only a 43" x 43" minimum opening, making it ideal for compact lofts, attic access, and secondary staircases where every inch counts. Adjustable rise options from 8-1/8" to 9-1/2" and a universal landing that adapts to square or round openings provide installation flexibility, and the kit ships ready for straightforward DIY installation with common tools.
Personalize your staircase by combining two beech wood tread finishes (Natural or Walnut) with a White or Black powder-coated steel structure and railing. Choose a plastic or composite (straight or helical) handrail to complete the design. Elevate your home with the Denver 41" Spiral Stair Kit, where the warmth of real wood meets the strength of steel in authentic Italian craftsmanship.
