Features

  • Thoughtfully Sustainable - Summa’s cylinder and base are made with an environmentally neutral Chrome 3 finish, rather than Chrome 6, a finish often used in the manufacturing process that is hazardous to users and the environment. The chair also features our chrome-free leather, an alternatively tanned leather that eliminates chromium, a harmful chemical used in most methods for tanning leathers.

  • Refined Comfort - Utilizing only one discreet height adjustment lever, Summa features a weight-compensating recline mechanism for unexpected ergonomic comfort and support. Integrated armrests attached to the chair back move with the user for complete support throughout the workday.

  • Visually Timeless - Summa's sleek contours extenuate the chair's thoughtful design. Utilizing only one simple yet discreet height adjustment lever, Summa eliminates large knobs for a perfectly contoured and timeless aesthetic. Between seven leather finishes and two back options, Summa can be customized to match any palette in any environment.

Design Story

The goal for Summa was to create a chair that was comfortable while exuding beauty and luxury. For executive conference chairs, this combination is quite uncommon - although beautiful, most are stiff and uncompromising to the user.

Summa’s shape is enveloping and inviting, while its crafted materials create a sense of visual harmony. Coupled with Humanscale’s self-adjusting technology, Summa eliminates the need for bulky knobs or levers to provide visual consistency from every angle.

Designed specifically with executive boardrooms and offices in mind, Summa’s enveloping shape and sculpted materials converge for a truly harmonious design that exudes luxury in every detail. Utilizing only one discreet height adjustment lever, Summa features a weight-compensating recline mechanism and integrated arm-rests for exceptional ergonomic comfort and support.
