What Makes a Chair Ergonomic?
What makes an office chair ergonomic? It’s a question we’re often asked, and it comes down to adjustability. While a standard chair provides a fixed seating position with little or no flexibility, an ergonomic chair is adaptable to suit each user’s unique physique and posture.
Features range from seat height and depth adjustments to customisable back, head and armrest support. These office chairs are flexible, versatile and designed to provide personalised comfort during long shifts at work.

Your Guide to Ergonomic Office Chair Features

Seat Height
Gas lift adjustments to raise or lower your seat height. Helps keep thighs angled correctly and feet flat on the floor, preventing leg strain and back pain.

Seat Slide
Seat slide adjustments to suit your body height. Keeps a small gap between the seat edge and the back of your knees to improve circulation and comfort.

Backrest Height
Height-adjustable backrest can be raised or lowered to suit the natural curve of your spine. Aligns with your lower back shape for better posture support.

Independent Seat Tilt
Tilts the seat independently from the backrest. Makes it easier to find a comfortable seating position to suit your work. Various lockable positions for firm support.

Synchro Tilt
Aligns the back recline and seat angle together for a synchronised tilt. Often set at a 2:1 ratio to promote natural movement, improve circulation and ease strain.

Tilt Tension Control
Weight tension control lets you adjust tilt resistance for a smooth and supportive recline. Encourages natural movement to prevent aches, strains or stiffness.

Standard Lockable Tilt
Locks the chair in various seating positions for firm support during key tasks. Tilt can also be unlocked for ‘free float’ mode, offering greater freedom of movement.

Adjustable Lumbar Support
Fills the gap between your lower back and the backrest. Maintains the spine’s natural inward curve for better posture. Prevents slouching and reduces back pain.

Inflatable Lumbar Support
Inflated using a connected hand pump. Same benefits as adjustable lumbar support. Stops your back from flattening and distributes upper body weight evenly.

Non-Adjustable Fixed Armrests
Strong and robust, providing fixed support for the elbow and forearm. Great for resting your arms during a break. Fixed arms make it easier to get in and out of the chair.

Height-Adjustable Armrests
Arms can be raised or lowered to suit your desk height and seating position. Stable support for the elbow and forearm. Reduces RSI when using a keyboard and mouse.

Multi-Directional Armrests
Armrests move up, down, forwards or backwards. Some also pivot inwards or outwards for unrivalled versatility. Prevents RSI. Eases strain on the back, shoulders and neck.

Height-Adjustable Headrest
Headrest can be raised or lowered for personalised head, neck and shoulder support. Prevents hunching and eases tension, reducing the risk of headaches or migraines.

Height & Tilt-Adjustable Headrest
A height-adjustable headrest that can also be tilted for even greater support and comfort. Reduces neck and shoulder complaints while helping to prevent headaches.
