The history of the Italian design manufacturer Opinion Ciatti goes back to the 50s. In the 3rd Generation the company is now led by Lapo Ciatti, who joined the company in 2006. At the same time, the brand name CCR was renamed to OC. Bruno Rainaldi, who had been leading the company for years, retired in 2011 and left a major cultural and creative heritage behind. Lapo Ciatti and his unexhausted passion for design, are since the driving force Opinion Ciatti's. The collection today includes bookcases, mirrors and chairs. It extends to the design of the future but of any room with functionally necessary items that will last for form and function, their time. Among the well-known products are the books column Ptolomeo and the the system 5 blocks.
