I'm the Gregory Inca Round Back Drafting Chair, designed in Australia by expert physiotherapists to deliver unmatched ergonomic support at elevated workstations. Perfect for architects, designers, and lab professionals, I keep your posture aligned and your comfort consistent - no matter how high your desk is.
My Dual Density Posture Support seat features a firm core for spinal stability and a softer outer layer for pressure relief, helping you stay comfortable and focused through long hours of standing-height work.
With my adjustable seat height, tilt, and ratchet back height, I adapt effortlessly to your body and workspace needs. My foot ring and drafting gas lift provide added balance and leg support, ensuring ease and stability while seated higher.
Built tough and AFRDI-certified, I can support up to 160 kg and am crafted to last in demanding environments. Choose from a range of seat sizes, premium fabrics, wools, or anti-microbial vinyls to match your workspace style.
Experience elevated ergonomic comfort with the Gregory Inca Drafting Chair - combining innovation, durability, and genuine Australian design for professionals who work above the rest.
Note: Seat height is measured under a 70 kg load for accuracy; an unloaded chair may read slightly higher.

Just wrapped: Our latest fitouts.
They’ve just been really easy to deal with. So an initial enquiry, a conversation with them and to be honest the process has been quite seemless from beginning to end. We’ve continued to use them for over five years now.
