When an idea is a good one, it naturally tends to evolve into new shapes. This also happened with the Dua project by Läufer & Keichel: starting with a small upholstered chair consisting of two curved and elliptical surfaces, hence the name Dua, a rich and extensive family of products was created, which now also includes a lounge chair. The seat cushion, thicker than before, is embraced by a wide and inviting backrest. Upholstered in fabric or leather, Dua Lounge is comfortable, elegant and visually light thanks to the slimline metal trestle base. Frame finish: polished aluminum, "Exclusive" painted aluminumUpholstery finish: in fabric, leather, synthetic leatherThe Berlin-based studio Läufer & Keichel has created a chair and an armchair for Kristalia with soft, embracing lines. The name recalls the number two, which recurs throughout the design project starting with the two elliptical surfaces of the seat and backrest, which sensually revolves around the seat. Available with a slide-frame base or with four solid wood legs, the chair and armchair can be upholstered with the fabrics and leather in the catalogue, with the option of different upholstery for the seat and backrest to create contrasting or matching combinations.Dua also comes in a stool version with a slide-frame base.
