Optional Installation, Set Up and Training

Select this option to get the most from your purchase. One of our highly trained IST team will deliver the chair, show you what the knobs and levers do, explain good posture and demonstrate how to adjust everything for maximum comfort so that you can do it yourself in future.


The RH-300 features a lower back height and a choice of two different seat sizes. Pivot points at the rear and front of the seat help to maintain both a good posture and the natural s-curve of the spine. The chair is simple to adjust and the controls are easy to access.
