Herman Miller Setu chair

Setu Chair - Material Innovation

The details are in the materials.

From the tip of Setu Chair's polypropylene kinematic spine down to its category-first H-Alloy base, there isn't a molecule we haven't mulled. Because, as with every Herman Miller design, our products and materials are one. This honesty in materials has long been the cornerstone of design at Herman Miller, and Setu firmly holds true to this principle.

Setu Chair's not-so-secret secret-polypropylene.

After testing dozens of different materials for Setu Chair's kinematic spine we discovered the smartest solution was also the simplest. Yes, polypropylene. The same material used to make toothbrushes and garbage cans. But it's the unique combination of two different polypropylenes - a thermoplastic polymer for the spine's composite and ethylene-propylene for the spokes - that helps create Setu's kinematic spine for the perfect combination of strength and flex in such a lightweight form.

The fabric of Setu Chair's performance.

Setu Chair's suspension material, Lyris, works in concert with the spine to distribute your weight evenly and conform to your contours like no other chair. You'll discover it's a finely tuned elastomeric material designed to provide superior suspension as well as aeration and temperature control. It's yet another example of elegance in the name of performance.

Setu Chair's foundation innovation.

A proven material in other industries, H-Alloy aluminum has never been used in a chair. But, to us, this material made perfect sense for the base of the Setu Chair. Not only is it durable and anti-corrosive, the unpolished and uncoated aesthetic means no added labor or harmful toxins. The result - less eco impact and a lighter carbon footprint.

All Setu chairs are also available with a semi-polished base, manufactured from the same durable but lightweight anti-corrosive H-Alloy aluminium as the original. The top surface has been polished; the sides and bottom of the base retain the blasted finish. Providing a polish to the top surface of the base takes nothing away from Setu's environmental credentials, with this range still containing 44% recycled content and still be 93% recyclable at the end of its life. This is achieved by keeping the H-Alloy aluminium base uncoated and unpainted, reducing the harmful toxins associated with the manufacture of this material.
