The brand Pedrali can realize itself every object of its collection, thanks to the high specialization of its production departments. Until the end of the ‘90s metal has dominated Pedrali’s whole production. Afterwards the company has focused mainly on the research and on the introduction of innovative materials, such as plastics, which are well combined with metal, glass and other materials. The continuous research of new materials, technologies and innovative solutions has enabled the growth of new seats collections. Very important is the attention reserved to the quality and the resistance of the products. The department of Research and Development has at its disposal machines which test the resistance of chairs before they are produced. For this purpose, special certificates are given by the authorities in charge, according to the European laws valid both for seats and for bases. This makes every product suitable either for private or for public use. Technological research and experimentation are two fundamental aspects in which Pedrali continuously invests.
