The SUPREX is a simple yet durable mechanism designed for economical office chairs. One of its key advantages is the integrated connection between the backrest and the seat within a single mechanism.

The mechanism features built-in backrest height adjustment. The adjustment is made using a ratchet system.

Due to its design, SUPREX is intended to be used in the locked position — the user selects the desired tilt angle and then locks it in place.

The backrest support bar and cover are supplied as a complete set.
