I'm the original Gregory Inca - trusted by Australians for over 40 years. Designed by leading physiotherapist Peter Gregory and crafted locally in Australia, I'm built to keep you comfortable, supported, and focused through even the longest workdays.
My award-winning Dual Density Posture Support seat promotes perfect spinal alignment and relieves pressure where it counts most - helping you stay productive without the pain.
I'm fully adjustable - from seat height and tilt, to back angle and ratchet back height - ensuring a fit that's made just for you. My heavy-duty build supports up to 160 kg, and I've been AFRDI-tested to the highest standards for durability and ergonomic performance.
Want choice? I offer four seat sizes and three back sizes, making me ideal for every body type. Plus, as an Australian-made chair, I can be finished in your choice of house fabrics, premium wools, or anti-microbial vinyls for healthcare environments.
Choose me for proven ergonomic design, genuine Australian craftsmanship, and unbeatable comfort - the Gregory Inca difference you'll feel every day.
Note: Seat height is measured under a 70 kg load for accuracy; an unloaded chair may read slightly higher. Adding the optional "Seat Slide" raises the seat height by ~25 mm.

Just wrapped: Our latest fitouts.
I would certainly recommend JasonL to anyone looking for a fitout. The best thing about JasonL was not only the quality of the furniture, but how smooth the whole process was—easy to deal with, easy to arrange, including the installation.
