MB1 Lounge Chair
Self-cushioning polymer flexes as you settle in — a trick that won Mario Bellini's lounge chair the Red Dot and iF awards.
The MB group — armchair, sofa, and ottoman table — is roto-molded from a polymer that gives slightly under weight, so the comfort comes from the material itself rather than upholstery. It serves homes, offices, and hospitality settings, indoors and out. Find the matching MB 2 and MB 5 in the Heller collection.

Common Questions
Is it comfortable without cushions?
Yes. The self-cushioning polymer flexes slightly under body weight, which is the design's core idea — juries at the Red Dot and iF Design awards recognized it in 2004.
Can it stay outdoors?
Yes. The molded polymer withstands heat, moisture, and daily use, so it moves between living room, patio, and lobby without covers. Wipe clean with a damp cloth and a mild, bleach-free cleaner.
