Here is a really interlocking four piece cool stool from British manufacturer Established and Sons that gives you a variety of seating arrangements, and all of them look great. Designer and architect Zaha Hadid has created some head turning modern furniture for famous names including B & B Italia, Moroni Leather, and Sawaya, and I have a feeling the list will go on. Zaha makes great use of clean flowing organic shapes with the Nekton interlocking stools that can be used individually or as a larger seating system. The Nekton is a production version of the original that was part of the “Seemless” collection comprised from rotation molded Fordacal. Established and Sons has a wonderful assortment of furniture that ranges from very modern to classical contemporary.
