As a replacement for the existing loose tables, a fixed table system with invisible fastening in plug sleeves previously integrated in the floor structure was developed. The tables are interconnected and are therefore always in perfect alignment. Electrical sockets with a cable channel in the table cross-beam integrated below the table top solve the previously chaotic cabling problem. The multiplex table tops were covered with a rubber covering. In the rear area of the hall, two rows of tables can be converted into a large conference table using table tops that can be placed loosely.
