A design that has stood the test of time. Used by different people. Day after day. And it has coped with every demand. Collection TEC is based on pioneering active sitting technology from MartinStoll, combined with top-quality materials and manufacturing. A chair that is a delight to sit in and to look at. And great value for money. The Synchronous-Torsion-System (STS) with its adjustable backrest tension can be optionally equipped with the active pelvic support. This prevents the pelvis from backward inclination and maintains the vertebral column in its physiologically correct position. In the version featuring a shoulder support, the swivel chairs provide extra comfort for the back. For the visitor segment, the Collection TEC is complemented by cantilever chairs. Due to their unpretentious design language, the chairs of the Collection TEC correspond with the most diverse office furnishings and interior designs. They can be combined to harmonise with every desk series in the Kinnarps ranges.
