Introduction
Werner Löffler, an expert in ergonomic seating and a passionate collector of seating furniture, developed the ERGO TOP technology in collaboration with the Technical University of Munich. This technology has been incorporated into Löffler's swivel chairs for 18 years, promoting dynamic sitting. The Tango chair is a notable piece in the Löffler collection, designed by Werner Löffler.

ERGO TOP Technology
The patented ERGO TOP technology is based on the concept of "dynamic sitting," featuring a fully movable seat surface that counters static sitting. This movement nourishes the intervertebral discs, keeping them elastic, and promotes an ergonomic posture by tilting the pelvis forward, maintaining an upright position without backrest contact. The IGR recommends this technology for unrestricted dynamic sitting, and it is certified by the LGA.
