Since the mid 1960’s, Grassoler has been manufacturing the inside structure of our sofas with metal frames, which were patented as Intelligent System®. The laminated steel makes the sofa frame structures indestructible so that they can be enjoyed for many more years than traditional wooden frames. The Intelligent System® provides you with a “customized suspension system” meaning that you can personalize the level of firmness in the seat to your own desire. There are three different firmness options: soft, middle and firm.
As a result of the exellent material quality, we offer a 25 year warranty of the steel structure, absolutely exceptional in this market sector.
