An extreme and praise-worthy focus on sustainable, eco-friendly design and gorgeous aesthetics come together with research-backed ergonomics at Humanscale. A through-line can be seen in all Humanscale’s more recent products — simplicity. Simplicity urged forward by the late American industrial designer Niels Diffrient in his partnership with Humanscale, which yielded two of the most notable and respected chairs ever — the Freedom and Diffrient World.
Summa, an executive chair by Humanscale made for today’s dynamic leaders, is now ready to order. An effortless blend of luxury and simplicity, Summa’s defined aesthetic and sophisticated palette is well-suited to high-end executive spaces within the workplace. The executive chair has a single, discrete height-adjustment lever seamlessly designed into the seat, unlike most chairs which have multiple exposed adjustment levers. Complementing its enveloping shape and sculpted materials, Summa features Humanscale’s signature weight-compensating recline mechanism and integrated arm-rests for exceptional ergonomic comfort and support.
