K22 Operator Chair

Synchronised recline with floating lumbar support, at a genuine everyday price point – The K22 is a high-back ergonomic chair built for versatile workspace fitouts and everyday professional use, combining a 2:1 synchronised recline mechanism with floating lumbar and pelvic support (available with a mesh or fabric seat, and an optional ergonomic headrest).

Rated to 150kg and specified for use up to 24 hours a day – K22 carries a 10-year manufacturer's warranty in single-shift settings, reducing to 3 years in continuous 24-hour environments. It features a single-paddle lever control for seat height and dynamic movement, direct tension control calibrated for users from 51kg to 149kg, and multifunctional armrests with soft-touch pads that can be removed entirely.

Key Highlights:

• Synchronised recline mechanism (2:1 ratio): Seat and back move together in a coordinated motion as you lean back
• Floating lumbar and pelvic support: An integrated lumbar curvature that moves with you, supporting the lower back and pelvis
• Height-adjustable backrest: Five settings, with reinforced upper-back thoracic support
• Multifunctional armrests: Soft-touch pads, fully removable without compromising the chair's design
• Optional ergonomic headrest: Retro-fittable, with independent height and angle adjustment
• Aluminium five-star base: Polished finish fitted as standard

Straightforward controls built for consistent, correct use across an organisation – K22's pictorial button layout is designed so adjustment stays intuitive whoever is sitting in it, encouraging the postural changes that reduce strain over a working day.

• Seat height (lift): Sit on the seat and pull the lift lever to set your feet flat with knees near a 90° angle
• Seat slide (depth): Lift the slide button and adjust so there's a 20–40mm gap behind the knees
• Tilt tension control: Pull out and turn the mechanism to set neutral resistance for your weight, or leave unlocked for free-float dynamic movement
• Back height: Lift the back of the chair until you hear it click into your preferred position; lift to full height and drop to release
• Ergonomic headrest (where fitted): Tilt, lift or lower to your preferred position

Why it matters

Even a well-engineered chair won't help if it's set up incorrectly — you'll carry the same aches into a new chair. This guide covers the small, high-impact adjustments that fix the cause, not the symptom, so your chair delivers the comfort and support it's built for.

How you receive it

Place any order and we'll email your download link as soon as your order is confirmed. Open it on your phone, tablet or laptop and follow the steps as you set up your chair.

The Apex Ergonomics Pack is available only to Apex Comfort customers — not included when the same chairs are bought from general retailers or marketplaces.
