SERAPID's patented Quick Seat eXchange (QSX) auditorium conversion system brings new possibilities to variable auditoriums and multi-purpose halls.

It allows fast, fully automated conversion from a free, flat parquet floor to an auditorium with flat or staggered seating tiers, and works not only with straight but also with beveled and curved seating tiers. A conversion takes only a few minutes and allows for a wide variety of performances with optimal utilization and cost-effectiveness.

The basis for the lift systems used in QSX is the rigid chain technology developed by SERAPID.
