Used by the thousands and successfully tested under the toughest conditions, these chairs can be found in trade fair halls, event halls, museums, churches, town halls and cafeterias. They fulfill the requirements of mass seating: they can be stacked, easily connected, are easy to take care of and are very comfortable. The clever row connection (Thonet patent) makes them additionally special. The frames are connected without any extra parts. This system offers two economical advantages: the comfortable chair width of 58 cm has a row axis dimension of only 53 cm. Several chairs can thus be placed on a surface and handling the chairs is so simple that assembly and disassembly times are clearly reduced.
