A square spiral staircase, ideal for optimizing space in confined environments, providing both functionality and adaptability. QUADRA is the square spiral staircase, designed for installation in spaces confined by two or more walls. Its unique configuration allows it to be mounted close to perimeter or interior walls, with steps designed to maximize the available space and perfectly fit any corner. This solution is particularly practical and functional in settings where space optimization is a key requirement. STEPS: Made of solid beech wood, 40 mm thick. Knot-free and crack-free, ensuring maximum stability and mechanical strength thanks to Finger Joint technology. Non-toxic water-based paint: 3 layers of varnish.
