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.

  • Wood

    Wipe with a soft, slightly damp cloth and dry immediately — do not allow moisture to sit on the surface. For marks, use a furniture-grade cleaner suited to wood. Avoid abrasive pads and prolonged direct sunlight, which can affect the finish over time.

  • Frame, Base & Components

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

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

An effortless blend of luxury and simplicity.

    Stunning craftsmanship

    Stunning craftsmanship. The wood back really stands out and makes a bold impression. I docked one star only because I wish it had a few more stain options, there's not really a nice neutral in between color option.

    The wood back gives this chair such a refined, sculptural look. It feels solid and luxurious, yet the ergonomic design still makes it comfortable for long meetings.
