I'm the Gregory Boxta - Australia-made and designed by a leading physiotherapist to keep you supported, comfortable, and focused throughout your workday. With my modern square back, I bring both style and spinal care to any office.
My award-winning Dual Density Posture Support seat promotes perfect spinal alignment, reduces pressure points, and helps you stay productive without discomfort, even during long hours of sitting.
I'm fully adjustable - from seat height, tilt, and back angle, to anti-slip ratchet back height - ensuring a personalised fit for every body type. I'm AFRDI-certified to support up to 160 kg and built for long-lasting durability.
Choose from small, medium, or large seats, with medium or high back options, and customise my base, arms to suit your style and workspace. You can personalise me with your choice of home fabrics, premium wool, or anti-microbial vinyls ideal for healthcare settings. With me, you get proven ergonomic design, genuine Australian craftsmanship, and unbeatable comfort - the Gregory Boxta difference you can 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.
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.
