Mario Bellini’s MB1 Chair is a masterwork of modern indoor-outdoor seating, designed in 2003 and honored with both the iF Design Award and Red Dot in 2004 . Made from self-cushioning, roto-molded polyethylene with Worry Free Plastics™, it’s impressively lightweight, yet durable enough to withstand heat, moisture, and everyday use . Whether on your patio, home office, or a sophisticated hospitality space, the MB1 delivers exceptional comfort and sculptural elegance. Available in crisp white and deep dark grey, this iconic chair is a timeless commitment to sustainable design.

For over 50 years, Heller has redefined what modern furniture can be—industrial in process, sculptural in form, and endlessly sustainable in spirit. Founded in 1971 and proudly manufactured in the USA, Heller partners with some of the most celebrated names in design—Massimo and Lella Vignelli, Sergio Asti, Mario Bellini, and Frank Gehry, among others—to create bold, enduring pieces that are as collectible as they are functional. Their designs live in the permanent collections of MoMA, the Centre Pompidou, and the Philadelphia Museum of Art, and remain icons of modern living—equally at home in an urban loft or a sunlit patio.

At Comosum, we’re proud to carry Heller because their values mirror ours: timeless design, radical sustainability, and a commitment to originality. Every product is crafted using recycled or recyclable materials and part of a groundbreaking closed-loop take-back program—meaning nothing ever ends up in a landfill. With innovations like Worry Free Plastics™ and NFT-backed certificates of authenticity, Heller is setting new standards in circular manufacturing and design transparency. This is furniture made for now, designed for forever, and backed by a vision of modernism that never imitates—only evolves.
