*In a study performed at the University of Central Lancashire, our APEX POSTURE chair was found to improve spinal alignment and reduce peak seating pressure.

APEX POSTURE is the cornerstone of the PSI Seating Posture Range. The chair features a synchro mechanism with independent forward seat tilt, back angle adjustment and multi-position lock. Each control has been designed with ergonomics in mind to enable the user to adjust their body for optimal posture and maximum comfort.
