How it works

Hover over a card, or tap it, to see how it works.

Seat Height

Lift the lever under the seat. Take your weight off to go up, sit down to go down. Let go to fix it.
Tilt Multiple Positions

Pull up the lever to unlock, lean back to the angle you like, then push it down to lock it there.
Synchronised Mechanism

Just lean back. Back and seat work in a 2:1 ratio when tilting back.
Manual Tension Control

Turn the knob under the seat. Turn to + for a firmer rock, − for a softer, easier lean.
3D Arms

Three ways: up and down, forward and back and swivel the pad (seen from above) to follow your arms.
2D Adjustable Headrest

Slide it up or down to meet the back of your head, then tilt it to suit.
Up to 110 kg

Built and tested for people up to 110 kg (about 17 stone), for everyday office use.
8 Hour Use

Made for a full working day comfortable for up to 8 hours’ sitting, every day.
5 Year Warranty

5 years of cover on every part, if a component fails through a manufacturing fault, we’ll sort it.
EN 1335

A high back posture chair in black fabric, made for people who shift about in their seat. The seat and back pivot together from a point behind the back, so the support follows you as you lean, with a headrest and 3D arms to finish the fit.
