Summa, Humanscale’s first executive chair product for today’s C-Suite leaders, is pure function and simplicity, featuring a sleek, clean aesthetic from every angle. Unlike most chairs which have exposed levers for adjusting height, recline and tension, Summa’s height-adjustment lever is seamlessly sculpted into the seat. Like all Humanscale chairs, recline tension is automatically established by the sitter’s weight. For added support and comfort, the chair also features integrated armrests that move with the user as the chair reclines.
 
For twenty years, Humanscale has created high-performance, supportive chairs with a weight-compensating recline, instantly accommodating each unique sitter by automatically adjusting to his or her weight. Providing long-lasting ergonomic comfort, Summa is one of the brand’s first entry into conference seating and the result of a design collaboration with Gensler, the world-renowned architecture firm. While designed for boardrooms, Summa’s versatility takes it from the corner office to the boardroom to the executive home office.
 
“Comfort and the ability to move freely are important everywhere in an office — including the boardroom,” says Humanscale Founder and CEO Robert King. "We are thrilled to offer a simple and elegant executive chair that elevates the sitting experience."
 
Summa’s multiple configurations, finishes, and leather options offer the opportunity to create a truly custom chair. Launching in Quarter 4 2019, Summa will be available in an upholstered back with wood back options to follow. Summa can be specified with casters or glides for added flexibility. In line with Humanscale’s mission to use Red List-free materials, Summa’s cylinder base utilizes environmentally neutral Chrome 3 instead of Red-Listed Chrome 6, which can pose health risks during the manufacturing process.
 
Humanscale is introducing Summa in a new line of chrome-free leathers available in seven colors. Luxurious, elegant and enduring, Humanscale’s new chrome-free leathers are better for both the user and the environment. Its alternatively tanned leather collection is manufactured by Wollsdorf Leather – a carbon neutral tannery – and does not utilize chromium, a harmful chemical used in most methods for tanning leathers. In addition to being more environmentally conscious, Humanscale’s premium leathers exceed industry standards in performance and durability. Humanscale is aiming to become the first manufacturer to offer chrome free leathers exclusively for its entire line of upholstered seating within the year.
