After more than 21,500 examples sold world-wide, Trasforma develops and becomes Trasforma Design, the new project where Rintal re-invents the wooden stair for interiors that has made "Climbing Made in Italy" part of the story.

Safe and functional design
Trasforma Design distinguishes itself from the other staircases for its large adaptation to every style and space requirement, guaranteeing functionality, safety and design in every installation enviroment.

Eco-sustainable design
The restyling from where Trasforma Design comes is also from the ISO 9001/2008 certified production processes and use of innovative and eco-sustainable materials. The steps and structures are made of multi-layer beech wood; this material allows reducing the amount of wood alternatively used for producing the same components in solid wood, without jeopardising the final product's quality and aesthetics.

Customisable Design
Trasforma Design was conceived all Customer freedom to choose from a wide range of finishes, components and accessories to create the most suitable stair for interiors for one's own style and furnishing requirements.
And, thanks to the product configurator, creating one's dream stair is even easier and intuitive.
