The chair Solitär was the first chair designed by John Kandell for Källemo in 1985. The model was shown at the Stockholm furniture fair in 1986 and was then much debated and called "the most idiosyncratic chair of the year". It was executed in mahogany and later in birch with leather seat. Borås city later ordered a chair in patinated bronze. According to Källemo this is one of only three chairs executed.
Solitär was the beginning of a lifelong friendship between John Kandell and Källemo's director Sven Lundh. The duo had a great influence on Sweden's design scene during the 1980s and 1990s. John Kandell is known for choosing his own path throughout his career. He was educated both as a designer and as a sculptor which influenced his approach and practice in furniture design. Solitär does in many ways represent the essence of Kandell's playful and sculptural aesthetics.
