Product Details

Cosm’s Auto-Harmonic Tilt puts the person first and responds to them – no matter their posture – providing a balanced recline and personalised comfort. Studio 7.5 and Herman Miller perfected the self-adjusting tilt by inventing and engineering a complex finely tuned mechanism. Accounting for the sitter’s vertical force the gears within the tilt move the fulcrum along a leaf spring to automatically adjust the tilt’s tension.

Cosm’s Leaf Arms which feature a soft but firm cradle design that provides a large cosy resting place for your elbows. The sling design makes holding a phone or book natural and comfortable and the angle of the arms means that they don’t get in the way of a desk.

Cosm has achieved Ergonomics Excellence certification from FIRA which is in addition to BS EN ISO9241-5:1999 and BS EN 1335 Part 1
