Australian Made

The story began in the mid 1980’s when physiotherapist and company founder, Peter Gregory, was commissioned by Colgate-Palmolive to investigate injuries in the office workplace. The culmination of his research was the unique and patented Dual Density Posture Support System, which has been recognised by ergonomists and occupational health and medical professionals as providing a superior seating solution for improved office efficiency.

Peter Gregory’s findings led to a patenting the award winning Gregory seat design Dual Density Posture Support.

Dual Density features firmer foam in the front half of the seat and softer foam in the back half. The separation of the two foam densities is indicated by the split. The pelvis gently ‘sinks’ and is supported in the softer section in the correct seating position at the back of the chair. Firmer foam at the front discourages the pelvis from sliding forward into the slouching “C” curve of poor posture. The moulded foam also encourages and improves blood circulation behind the thighs. With the added height adjustable lumbar support the spine is maintained in the healthy, upright “S” curve of good posture which also creates less stress on the arms, shoulders and neck throughout the day.

I wanted to thank you for the quick delivery of the Gregory Inca chair. I am a trained ergonomist and have recommended these chairs to clients when I was a rehab consultant for many years. I have an acute episode of backpain and it is such a relief to have a chair which is fully ergonomic.

I've had a Gregory chair at work for the last 15 years and found it the most comfortable for my body shape. During the Covid lockdown I needed to find a work chair for home and was so happy to be able to find the same chair after enduring a couple of week of back pain without my work chair.
