i29 – Mesh Office Chair


The i29’s ergonomic engineering delivers superb support and dynamic movement

The i29 boasts one of the most intuitive mechanisms on the market. With three easy-to use pictorial controls on the right-hand side operating seat height, seat depth and advanced dynamic movement, the mechanism can also be locked at any angle. This works like a knee tilt mechanism with the first articulation at the underside of the thighs and the second point under your sitting bones (ischial tuberosities), delivering constant support in active mode and reducing the pressure on the underside of the user’s thighs.

The extendable direct tension control adjusts the resistance of the chair to comfortably balance users weighing from 8 to 23.5 stone.

The fully patented floating lumbar support automatically moves with you when in dynamic mode, giving continuous lumbar support. The chair’s split back is designed to deliver independent upper back support as well as ensuring the patented lumbar system protects the lower regions – keeping the user’s pelvis rotated.

The back can easily be height adjusted for each user’s anthropometic measurements by releasing two buttons on the back of the chair.

The i29 is fitted with an aluminium five-star base as standard.

The 4D multi-functional arms incorporate three buttons to increase armrest length, width and height which can be locked in position. The angle of the armpads can also be adjusted to suit. The chair arms of the i29 can be removed easily leaving the design uncompromised and safe for users.
