Hello, I'm the Gregory Slimline - a high-back ergonomic task chair proudly designed and made right here in Australia. I was created with physiotherapist expertise to keep you supported, comfortable, and focused throughout your workday.

My contoured back gives you exceptional lateral and lumbar support, plus increased thoracic support to keep your posture perfectly aligned, even through long hours of sitting. My fully upholstered outer back adds a touch of softness and sophistication - because great ergonomics should look and feel good.

Inside, my Dual Density Posture Support seat blends firm inner support with gentle cushioning to relieve pressure points and promote healthy spinal alignment - so you can stay comfortable and productive all day long.

I adjust to fit you perfectly, with seat height, tilt, back angle, and anti-slip ratchet back height adjustments that make sure every position feels just right. I'm AFRDI-certified and built to support up to 160 kg, so you can count on me for strength, comfort, and durability.

You can choose my seat size and back height - small, medium, or large seats, with medium or high back options - and customise me with height-adjustable arms, aluminium bases, and a wide range of fabrics, from stylish wools to anti-microbial vinyls ideal for healthcare environments.

Choose me for proven ergonomic design, superior support, and genuine Australian craftsmanship. I'm the Gregory Slimline - and I'm here to support you every day.

Note: My seat height is measured under a 70 kg load for accuracy; when I'm unoccupied, I might sit a little higher.
