By combining structural and flexible zones in its plastic frame, Sequa’s mesh backrest forms a highly adaptive structure which can dynamically follow every movement while always providing optimal support. For this chair Itoki developed a frame that moves in a 3-dimensional way never seen before in a mesh chair. The sides of the frame move inwards when under tension, which results in a highly comfortable self-adjusting pelvis support. The height adjustable lumbar support is mounted on a flexible rail which bends forward when reclining. This feature allows to increase support when reclining instead of decreasing like on conventional chairs.
