Entretien, maintenance et longévité

  • Upholstery

    Care instructions vary depending on the selected upholstery. Vacuum regularly using a soft brush attachment to remove dust and prevent dirt from working into the fibers. For spills, act quickly — blot liquids with an absorbent cloth before they set. Stains should be removed by gently dabbing with a lint-free cloth or sponge dampened with clean, warm water. If necessary, add a small amount of mild dish soap, then finish by dabbing with clean water. Avoid rubbing, as this may damage the textile surface. For wool textiles, professional dry cleaning is recommended for anything beyond surface stains. For detailed care instructions by upholstery type, refer to the Humanscale Care Guide.

  • Frame, Base & Components

    Clean metal and plastic components with a soft, damp cloth and mild soap if needed. Dry thoroughly.

An effortless blend of luxury and simplicity.

Summa's versatility takes it from the corner office to the boardroom to the executive home office.

    Chair feels like it

    This chair feels like it belongs in a Forbes cover shot. The leather is buttery soft, the lines are clean, and it just feels… indulgent. I can sit here for hours and still feel supported.

    Enveloping back and integrated

    The enveloping back and integrated arms make it feel like the chair hugs you. Definitely a different level from other executive chairs I’ve tried. Worth the price.

    Really elegant

    Really elegant, very well made. I love all the color options, but the price increase for leather seems a little unreasonable. Ended up going with a more basic fabric
