Trio 180° is the space-saving staircase with a prestigious design, born from the collaboration between Rintal and Giugiaro Architettura to enhance small spaces.

It takes up half the space of a spiral staircase

The modern and attractive design makes it unique among indoor space-saving stairs which can rarely boast of such a successful mix between functionality and aesthetics.

Trio 180° in fact takes up only half the space compared to prefabricated indoor stairs, helical or spiral, allowing you to reach the upper floors in half the space and without sacrificing design. Its special shape allows you not only to use any architectural space available but also to turn it into a beautiful and innovative design solution. This is possible thanks to the particular shape of the steps that reduce the tread without reducing the support of the foot surface. Furthermore, their sinuous and undulating shapes follow the embrace of the spiral structure, creating a composition of great modernity and aesthetic harmony that enhances the surrounding environment.

Design and functionality

The mini spiral staircase Trio 180° is made of a central pole to which the steps are attached. The pole is in black painted steel, matching the handrail in Moplen and the railing Tube. The steps are made of solid finger joint beech wood and are available in various finishes. They can all be painted the same color, choosing between the natural tones, or turned into the two-color version, choosing a color sample to alternate with black, always present to maintain chromatic harmony.

No other model of space-saving stairs for mezzanines offers the same versatility of design: the exclusive design of Trio 180°, thanks to Rintal Stair System, can be declined in several colors to make it consistent with the environment in which it is inserted.

Great design by Giugiaro Architettura

A solution not only practical and sturdy, but also a high aesthetic level which allows you to furnish even small apartments with high quality design. With Trio 180°, a mini staircase for small spaces becomes a furnishing element in rooms with a contemporary décor, able to satisfy all the needs related to functionality as well as fulfilling the wishes of the designer.
